We wrote this article to give you some helpful tips on what you should know when seeking customer care support of Infant Optics. Though easy, this guide may save you time and resources.

Excellent Reviews of Infant Optics Support Team

If you read the reviews of Infant Optics before making your purchase, you must have realized that their attention to customers is unmatched. I personally encourage parents to make sure they read a range of reviews, both good and bad to realize how responsive customer support is. If you can easily locate a phone number of email, it may make a big difference.

Some manufacturers of baby monitors have a history of giving poor customer support or not meeting their promises. One example is Anker Electronics, the manufacturer of Eufy Spaceview baby monitor. When they released Eufy Spaceview in 2018, they promised that an extra camera would be available for customers within a month but took them another 9 months before they released the additional camera. A way to know if a brand is not responsive to customer queries is by going through their one-star reviews. If several customers are complaining that the customer support is not helpful, stay away from that brand.

Key Issues Customer Service Will Troubleshoot

  • Infant Optics AC plug/adapter not working or the infant optics battery won’t charge – Parents who have experienced this problem have contacted the support team and received a battery replacement if the unit was within the warranty period. If it is out of warranty, the customer care representative of infant optics may advise you to replace the entire unit and in this case, you’d need to ship the entire Infant Optics DXR 8 to their location in California. It will cost you $6 which is quite reasonable.
  • Infant Optics power button not working – After some period of use, the power button and the buttons for adjusting volume or brightness can become unresponsive. I went through several troubleshooting tips that have worked for other users but wasn’t lucky. Several users who’ve had this problem finally had to contact Infant Optics customer support and those with valid warranty were able to get replacements of the screen. When you first contact the customer care, they may try to guide you on how to ‘fix it’ but will ultimately tell you how you can claim warranty to fix the buttons that are not working. If your baby monitor is out of warranty, you should still consider contacting Infant Optics as thousands of clients have indicated that they still got brand new units, despite the expiry of the warranty. Don’t quote me on this though.
  • Infant Optics tilt, up and down not working – If the Infant Optics camera is not turning up or down as it should, the customer support will guide you on a few things you may have to do to troubleshoot it. Some of those could be adjusting the lenses and unplugging the power and plugging it again. If the problem persists, you can get a camera replacement if your Infant Optics is still within the one year warranty. You can however still get a replacement if the warranty has expired. The customer service will guide you on how to claim the warranty.
  • Infant optics camera not working in the dark or no sound – In case any of the units including the microphone, the speaker, battery or camera are defective or not functioning properly either because of negligent damage or other causes, you should contact the infant optics support.
  • Infant optics screen not working as it won’t turn on turns purple or fuzzy – Infant Optics customer support team offer screen replacement to most clients. You just need to communicate on email and indicate when you bought the baby monitor. If your baby monitor is within the one year warranty, they’ll advise you on how to claim the warranty.

Can Infant Optics be hacked

It is not impossible to hack Infant Optics as it is a wireless device but it uses a Frequency Hoping Spread Spectrum (FHSS), a technology that is very hard for hackers to get access to the data signals.

Can I get a free Infant Optics battery

You may qualify for a free battery replacement if your Infant Optics is within the one year warranty but you need to check with their support team. If they are unable to give you the free battery, you can make the purchase on Amazon for just $6. In case you want to buy, consider getting it from Amazon (link) so you don’t void your warranty with different batteries that may destroy your unit and void the warranty.

What is Infant Optics battery life and can it be extended

The Infant optics claims that its the battery can last up to 10 hours. Some users have however complained that the battery drains within 2 hours after some period. Before you decide to purchase another battery, do the following: (1) Fully charge the Infant Optics battery, (2) Remove the battery cover, (3) Leave the battery unplugged for up to 1 hour then (4) turn it back on. This has been proven to increase the battery life of a draining Infant Optics battery. It must be something with the firmware that drains the battery.

Is there an Infant Optics App and can it connect to the phone

Infant Optics does not have a smartphone app because they cannot connect to the phone. Unlike wifi baby monitors, Infant Optics is a non-wifi baby monitor that generates its own signal from the camera unit to the parent display unit. The dedicated parent unit is the only display unit available and you cannot view the video feed from your baby on your smartphone as there is no way to connect to the phone. Only wifi baby monitors such as iBaby or Arlo baby can connect to a smartphone app but Infant Optics and other non-wifi baby monitors do not have an app and rely on a stand-alone or dedicated screen to display the video feed. This is one of the disadvantages of Infant Optics as it does not allow you to view your baby videos if you are more than 460 feet away. If Infant Optics had a mobile app that could connect to the internet, you could possibly view the videos from anywhere in the world.

The advantage of Infant Optics not having an app is that it loads faster on the display unit. Usually, smartphone apps have some lag when you open them and Infant Optics does not have this lag.

How to fix Infant Optics signal going in and out

If you get the signal going in and out continuously, there is a device that is interfering with Infant Optics signal. Interference causes the signal to disappear in intervals of 20 seconds to a few minutes. Any device that uses 2.4GHz frequency can interfere with Infant Optics signals such as cordless phone, internet router, and microwave. If you the signal is going in and out and you are within 10 to 20 ft. away, then it must be interference. Make sure the device that could potentially interfere is at a distance from either the baby unit or the display unit of Infant Optics.

How can I fix Infant Optics Screen that’s Purple or Pink

There are several reasons why the screen of Infant Optics could become purple but a quick fix that has worked for several users is unplugging the cable and making sure it is plugged in securely. A loose connection can cause this problem. Another fix that has worked for some users is rebooting your Infant Optics to make the purple or pink screen go away.

Has there been an Infant Optics Recall

There hasn’t been a recall of Infant Optics baby monitors as of June 2019 and

Can you turn off the low-battery warning sign?

Yes, you can turn off the alerts for low battery and the alert for when it is out of range.

How do I fix my Infant optics microphone not working

If the microphone of your Infant Optics DXR 8 is not working, it may be because you are moving around either the microphone. The microphone and the speaker will not work if you are moving. If you stop moving, the microphone should start working fine. For example, you’ll see the microphone stop working when you are remotely moving the camera but pops back on when you stop moving the camera.

Infant optics sound stopped working

If the sound of your Infant Optics stopped working, navigate the settings and select volume. Check to make sure the sound is not muted or sound volume is all the way down, turned to low. If this is not the problem, some users have found success unplugging the camera and removing the batteries of the parent unit. Do this and wait for at least 90 seconds. If these two suggestions do not work, you may want to contact Infant Optics support.

Infant Optics DXR 8 For Twins (in 2019)

Infant Optics DXR 8 For Twins (in 2019)

Infant Optics DXR-8 For Twins 2019

Infant Optics DXR 8 perfectly works for twins or monitoring multiple babies. If you have twins and wondering which baby monitor is secure and can enable you to watch both of your twins at ease, we highly recommend Infant Optics DXR 8. Infant Optics DXR comes with one camera but parents can buy an additional one for $ 100 dollars and get all the benefits of monitoring your babies with peace of mind.

As you consider which baby monitor is best for you, we always consider parents to come up with a list of things you consider important to you and your baby. Safety and security always come first and Infant Optics DXR 8 meets all the security considerations you need to review. Not all baby monitors that are non-wifi are secure and we’ve listed on a separate page why baby monitors that use FHSS technology are the most secure and why you should consider it.

There are other baby monitors that use the same technology but I don’t want to go into details of best safe and secure baby monitors. Infant Optics DXR 8 is our number 1 pick as a safe baby monitor and aside from that, it is a great baby monitor that can enable you to monitor your twins on separate rooms.

The following are great reasons that make Infant Optics DXR 8, the best baby monitor for twins;

  1. Number of Cameras – Although Infant Optics may be considered more expensive compared to other baby monitors as it currently sells at $165. It, however, comes with a lot of features which include expandability or the ability to connect one baby monitor to up to four cameras. Infant Optics that you get with $165 comes with one camera but you can buy up three more cameras to make a maximum of four which the baby monitor supports. In other words, instead of getting two baby monitors, you can only buy another camera and you can start monitoring your babies.
  2. The Display – Infant Optics comes with a 3.5-inch display which is average of most baby monitors. The smallest display you get is around 2.4 inches and the biggest is 5 inches. A few go higher to 7 inches but basically, you get a decent display size on Infant Optics to monitor your two kids. The baby monitor allows you to switch from one camera to another without having to switch from one baby monitor to another. You can use the same baby monitor display to view up to 4 cameras. You can see how you can switch on each camera on this video below:

The disadvantage of switching between cameras of Infant Optics DXR-8

A few disadvantage with switching between the cameras is that some of the cameras will stream lower quality pictures from the cameras. Only one camera gives the best quality pictures of your twins.

History of Baby Monitors (1937 to Present)

History of Baby Monitors (1937 to Present)

History of Baby Monitors

The history of baby monitors is tied to the history of radio broadcasting which developed during the first world war.  Radios were already very common in the 1920s but it took a very tragic incident in 1932 for the first audio baby monitor to be conceptualized. The Lindberg baby kidnapping incident is credited as having inspired Eugene McDonald, the president of Zenith Radio Corporation to experiment on an audio baby monitor which later became Zenith Radio Nurse.  Eugene McDonald first put together the basic microphone, speaker and a radio to listen to his daughter. When he was assured that the technology could work, he tasked a Japanese-American engineer, Isamu Noguchi to design the first baby monitor in 1937.

Newspaper snapshot

The invention of the First Baby Monitor – Zenith Radio Nurse in 1937

The Zenith Radio Corporation engaged Isamu Noguchi to design the first baby monitor in 1937. The audio baby monitor which was complete and ready for sale by 1938 was named Zenith Radio Nurse. It had a sound amplifying system with two units, the Guardian Ear and a Radio Receiver. The guardian ear’s analog intercom system transmitted sound on a 300 kHz signal transmitter over the power line. The communication was one-way.

The Zenith radio nurse first sold for $29.95 in 1938, an equivalent of $523 in 2019. This was quite expensive and in addition, it’s electrical transmission was plagued with technical problems, mainly distortions and RF interference. It shared a radio frequency with other consumer products, mainly the car radios and garage door openers. Below is how the Zenith radio nurse worked:

1. The Guardian Ear controlled a microphone, a sound amplifier, and an oscillator circuit(modulator ).

2. The generated circuit was conducted by means of the lighting circuit and was intercepted by the radio nurse

3. The receiver unit of the Zenith Radio nurse had a detector, sound amplified and sound reproducer.  The total amplification from the microphone to the speaker was in the order of 500,000 times. This was capable of making the slightest sound audible on the receiver.

The Zenith monitor did not work well with very loud volumes as it resulted in distortions and speaker rattles.

Following the Japanese attack of Pearl Harbor, the anti-Japanese sentiments swept through America and many receivers were destroyed, making them very scarce. In fact, it is now sold as an antique and can be found in a few museums. If you are interested and want to learn more about the Zenith Radio Nurse, you can read the original Zenith Radio Manual.

Below is an ad/commercial that appeared in a newspaper in 1938.


Evolution of Baby Monitors:1937 to 1970

The first designed baby monitor, Zenith Radio had one-way intercom and relied on an electrical circuit to transmit its analog audio signals


Because of the challenges discussed above, Zenith Radio Nurse model was not produced after 1938 and the few zenith nurses were bought by museums because of its unique “industrial design”.

Between 1937 and 1960s, most baby monitors in the market were sold by a few manufacturers that used Zenith’s expired patent and analog signals to transmit audio. During WW II, troops used hand-held analog radio devices to communicate and the biggest disadvantage was that only one conversation could occur at a time, on each channel. This is called the simplex mode.

The troops managed to overcome this obstacle by tuning receivers and frequencies to different frequencies but this was difficult as they were using the lower frequency bands, 27 MHz or 49 MHz. Basically, they were limited by the limited number of available frequencies. Below is a video describing analog baby monitors in the 49 MHz bands.  

Although analog radio devices were in use for a long period, they were mainly preferred because they had better ability to communicate especially when a received signal was weak and/or noisy. 

The Invention of Frequency Hopping Spread Spectrum (1941)

The history of baby monitors is very much tied to the invention of a secure communication protocol called Frequency Hopping Spread Spectrum (FHSS). The protocol was invented in 1941 by two Americans, Hedy Lamarr and George Antheil who patented their invention of a secure security protocol that successfully enabled the Allied Forces to communicate and steer torpedoes without being noticed or intercepted.

The technology utilized a spread spectrum sequence which basically allowed signals to hop from one sub-frequency to another during transit. The spread spectrum technology was named Frequency Hoping Spread Spectrum (FHSS).

The FHSS guarantees 100% privacy of all communications and the technology is now being used by some of the best-rated baby monitors such as Infant Optics, Babysense video baby monitor, Hellobaby, and Eufy Spaceview. We have a separate post with a list of top hack-proof baby monitors using FHSS technology which you can check out.

It is, however, important to note that while FHSS technology was discovered in the 1940s when the baby monitor industry was at its nascent stages, the technology was not used in baby monitors until the 90s. First, they had to discover digital signals to replace the analog baby monitors and enable encryption for better communication security. 

The Emergence Of Digital Signals and Rise of Digital Baby Monitors

In 1965, a digital processing signal technology was discovered which paved the way for the digital signals technology. 


Difference Between Analog and Digital baby Monitors


  • Analog baby monitors use analog radio signal that operates under 49 MHz frequency band
  • Analog baby monitors easily pick up noise and is prone to interference by other devices such as cordless phones which operates at a frequency close to 49 MHz (Cordless phones operate on frequencies bands between 40 and 50).
  • Analog baby monitor signal is continuous
  •  An analog baby monitor allows you to select from several channels in case the channels you’re currently utilizing has a lot of interference. Current monitors automatically scan the channels while old ones required users to manually select channels.
  • Analog baby monitor Signal does not travel long distance compared to digital baby monitors
  • The analog baby monitor signal transfer speed is significantly lower compared to a digital baby monitor.


  • Uses digital radio signal that operates under 1.9 GHz, 2.4 GHz or 5.0 GHz frequency bands. Those that operate in the 1.9 GHz are called DECT baby monitors.
  • Prone to less interference but still receives interference from devices that use the 2.4 GHz or 5.0 frequency band such as wifi routers.
  • Better quality data transferred – audio or video
  • Uniform signal reception. It has better coverage and the data does not lose its quality as the parent unit is moved away further from the baby monitor unit.
  • More signal capacity transmitted per second

Evolution of Baby Monitors:1970s, 1980s and 1990s

Baby Monitors in 1970s

1974: A patent was filed in Spain by Fernandez Aguado Rafael. The patent was for an apparatus for monitoring intercom. It’s was described as a device to monitor young children and patients. Apart from monitoring audio, the baby monitor would allow two-way communication. This baby monitoring device would be different from the Zenith Radio Nurse in that it allowed the caregiver or the parent to communicate with the baby. It was however designed to be similar to a telephone as it had a call button and a switch and some argue that this was not entirely a baby monitor.

1979: A patent for a breath monitoring device was filed James K. Frost in Australia and later in the US.

The device was designed to monitor the breathing of an infant and sound an alarm in case of a cessation. An electromagnetic transducer was attached to a ‘cot’ or baby’s crib and it was supposed to be compressed every time a child breathes.

The transducer was attached to a microphone and it continuously produced noise if the breathing is normal. It did send an alarm in case the breathing ceased.

Baby Monitors In 1980s

1980 marked a period of great progress in baby monitors technology. Patents for transmitter units, speakers, secure cords and receiver units were approved.


Companies such as Fisher-Price started manufacturing baby monitors as it had become a lucrative space compared to its traditional toys specialty products. Fisher-Price analog baby monitors were the best selling baby monitor brands in the 1980s. Mattel Inc. bought out Fisher-Price in 1993.  

Safety 1st 

Another baby monitor manufacturing company that emerged in the 1980s was Safety 1st which was formed in 1984. In 1987, Safety 1st released its first baby monitor which was the best selling brand by 1993. 

Baby Monitors In 1990s

The history of baby monitors cannot be complete without the 90s. The 1990s was marked by the emergence of several baby monitor manufacturers such as Safety 1st, a company that saw incredible success selling analog baby monitors. In addition, several patents were filed which paved the way for growth in the nascent baby monitor industry. Two factors majorly contributed to the growth of the industry: News media and FCC regulations. 

Factors that fueled the growth of the baby monitor industry in the 90s

  1. News Sites/Channels

Several TV news channels ran stories of what some cameras had revealed – mostly gross examples of caregiver misconduct when the parents were away. The shocked public began to buy the cameras, especially pinhole cameras. This fueled the development of nanny-cams, small discrete cameras which could broadcast video and audio for a range of up to about 300ft. By the early 90s, Hi-8mm video formats began to catch on. By Mids 90s, hand-held Hi-8 recorders were under $1,600 and dropped to less than $900 by 1999.

2. FCC Regulation and Baby Monitors

FCC also made several changes to regulations of audio and video transmission in the 1990s, mostly the range that signals could be transmitted and the frequency band. In 1995, FCC approved baby monitor electronic manufacturers to transmit signals in the 900 MHz frequency band and this significantly improved the audio quality as it reduced RF interference and noise. Towards the end of the 1990s, FCC also approved the transmission range of some reputable vendors to up to 3 miles. Safety 1st, one of the first manufacturers of baby monitors increased their sales by more than 50% in 1993.

Notable Baby Monitor Patents In the 1990s

The most innovative patent was the wireless baby monitoring device which operated in above the 900 MHz frequency band and was capable of operation at a relatively low DC power. This baby monitor only allowed one-way communication and was powered by batteries. This baby monitor was the first one to design a truly portable parent unit but it still had antennas to receive transmitted FM radio frequency and speakers for converting the received RF signal to audio signal. The transmitting units were capable of AC or DC operation and it had a transducer for converting an audio signal – such as a baby’s cry – to an electrical signal which is processed by the transmitter circuit. Before Wilson Law invented this wireless baby monitor, all baby monitors produced in the 1970s and 1980s used the 27 MHz or the 49 MHz frequency bands. In 1995, the FCC allowed consumer electronic devices to use the 900 MHz band (between 902 and 928 MHz). The higher frequency bands were desirable because it allowed more channels resulting in less RF interference and noise. 

This baby monitor consumed very small amount of power with DC operation. It could operate on small 1.5 V batteries and this was significantly improved as all the baby monitors in the 1970s, 1980s and early 90s used the 9.0. This innovation was submitted by Wilson Law in 1995 and was assigned to Golden Eagle Electronics Ltd.

In 1997, a baby monitor with playback and two-way communication was invented by Cynthia Altenhofen. The baby monitor allowed the caregiver or parent to record a soothing message for playback to the baby in response to activation of a play switch. This was the first baby monitor with a message storage mechanism.

The 2000s to 2015 – Rise of Video Baby Monitors

Prior to 2000s, most baby monitors did not use wifi to transmit signals. Analog baby monitors used the analog signal while digital baby monitors started using the 2.4 GHz WifiDECT or FHSS technologies to transmit audio and visual signals. It is worth mentioning here that some of the best baby monitors, the best-selling actually still use FHSS technology. Infant Optics DXR 8 and Eufy Spaceview are the two most secure baby monitors that still use the FHSS transmission technology. 

The Rise Of Video Baby Monitors – When Baby Monitors Became Popular

Prior to 2000s, baby monitors with a camera unit had gained a foothold in the 90s. As discussed in this article above, news outlets including TV ran several stories of nannies that were mistreating babies when parents were away. These stories were made possible by nannycams which basically recorded a video of the baby when the parents were away. Parents had seen the need to purchase baby monitors and as prices continued to fall in the 2000s and with the emergence of wifi baby monitors, baby monitors continued to become very popular.

Because of the stories, scared parents bought the nanny cams and by the end of 1999, video baby monitors were fairly known by a good portion of American parents. Another big development in the 2000s was the use of wifi to transmit signals. The internet has contributed immensely to the growth of the baby monitors. There are more than 30 patents relating to video baby monitors at present with most of them seeking to utilize the 2.4 GHz band that is used by wifi.

All these were filed within the last two decades and there are several other pending video baby monitor patents. Some of these baby monitors have had immense success with consumers. Arlo baby became one of the best-selling wifi baby monitors last year (2018) with parents being satisfied mostly with the picture and video quality. Video baby monitors are now being integrated with some of the smart home devices such as Apple Homekit, Amazon Alexa Echo, and Google Home Hub. Google has actually approved a list of cameras that are compatible with Google Home Hub and Arlo and Nest are some of the compatible baby monitors. 

Hacking of Baby Monitors

The first popular story of a baby monitor being hacked was reported by CNN in 2009. Since then, their thousands of cases of baby monitors being hacked and this has been the biggest critique of wifi baby monitors. Hackers have had a chance to exploit loopholes and access signals over the internet. We have a separate report on baby monitor hacking which you can read if interested. 

Notable Video Baby Monitor Patents:

Successive video baby monitor patents were filed by VTech in 2003, Jollybaby in 2008, Samsung 2011, BabyTech in 2012, Panasonic in 2015. BabyTech’s patent was for car baby monitor, a space that’s yet to gain momentum. These were patents for a basic video baby monitor without wifi and no back-up power. In 2007, Graco Children’s Products Inc. was assigned a patent for video baby monitors with back-up power.

Home Fetal Doppler

In 2009, FDA approved the sale of a commercial home-based fetal doppler, also called doptone. One of the first approved fetal doppler was Sonoline B and C.

Some companies that have some of the best performing baby monitors such as Infant Optics did not invent their technology but bought the license to manufacture a non-wifi baby monitor that has sold over 500,000 units. Infant Optics DRX 8 had been regarded as the best baby monitor of all times.

2015 Onward – Smart Baby Monitors

Several smart baby monitor companies that utilize machine learning, sensor fusion, and artificial intelligence to measure vital signs have emerged. These baby monitors have been attributed to saving lives from SIDs, among others. They track vital signs such as breathing, blood-oxygen level, heart rate, and sleep, among others. The American Academy of Pediatrics (AAP) however cautions parents and caregivers against these smart baby monitors. In a 2018 study led by Chris Bonafide, MD, smart baby monitors were found to not have any role in preventing SIDs. The report challenges the accuracy of pulse oximetry-based baby monitors. The report tested, Owlet Smart Sock 2 and Baby Vida. (You can read the 3-page report here).

Notable Smart Baby Monitors

1. Owlet Smart Sock 2

Notable among smart baby monitors is the Owlet Smart Sock. Owlet Smart Sock is a wearable monitor that uses pulse oximetry technology to detect the baby’s pulse rate and oxygen levels. Owlet launched its Smart Sock in October 2015 and has since sold more than 250,000 units after successfully filing a patent in 2014. You can read our separate post on Owlet Smart Sock 2.

2. Nanit Plus

Nanit, another smart baby monitor uses computer vision to measure and track a baby’s sleep. Nanit received its patent in 2017 and it’s the first baby monitor to use computer vision and is HIPAA compliant. The company founder and CEO Assaf Glazer have some of the patents to his name, including a patent for a portable mount for a monitoring camera. They received a patent period of 15 years! Both Nanit and Owlet are expensive compared to regular baby monitors each selling for at least $300.You can read our detailed review of Nanit Plus.

Selecting a Wearable Baby Monitor

Selecting a Wearable Baby Monitor

When the New Yorker Magazine chronicled a story of a parent who was regretting using wearable baby monitor, it was one of the first popularized article about the dangers of wearable baby monitors. Jake described the experience using three baby monitors as a first-time dad by reviewing Owlet smart sock, MonBaby Smart Button and Snuza Pico. Like several other skeptics of baby monitoring devices, Jake concludes his review by making a case that parents do not need any of the current smart baby monitors. 

Baby monitors are not medical devices

In this blog post, I have tried to explain a few misconception about some of the more sophisticated smart baby monitors that specifically track temperature, oxygen levels, breathing patterns and sleep quality.

It is important to note that none of the baby monitors are meant to keep babies safe from Sudden Infant Dead Syndrome (SIDS). In fact, the American Academy for Pediatrics has warned ‘Do not use home cardiorespiratory monitors as a strategy to reduce the risk of SIDS.’ In addition, FDA has not approved any of the smart baby monitors and it released a formal report in 2017 to urge the public not to confuse the smart monitors as medical devices. 

Who needs smart baby monitor?

FDA also advises parents to speak with baby’s doctor before using smart baby monitors. For normal babies, the monitors may not be necessary as Jake made the case but baby monitors are required if; 

  • If the baby has had an ‘Apparent Life Threatening Event’ (ALTE) like absence of breathing. In this case, the doctor could suggest an apnea monitor to keep track of baby’s heart rate and breathing. 
  • Premature babies have persistent breathing pauses or have a slow heart rate
  • A baby has a rare medical condition that necessitates tracking of breathing or body temperature patterns 

How wearable baby monitors work

Wearable baby monitors use sensors placed on the baby’s body to monitor things like heart rate, respiration, sleeping position, blood oxygen level or body temperature. The sensors are able to send the signal to the parent or the caregiver in case any of the above parameters fall outside the range of normal.

Types of Breathing Baby Monitors

There are several types of smart baby monitors and each device can measure many parameters but could be specialized to measure a particular item such as temperature, sleep patterns, oxygen level etc. 

  1. Breathing baby monitors that use movements – To provide extra safety and more health-related information about the baby, a baby’s breathing can be recorded by a mat placed under the mattress. The baby’s breathing can also be monitored by a monitor placed on the baby’s clothes such as diapers or pajamas. These monitors are portable and easy to install. They can however easily get detached or the baby could rollover in a different side of the bed that the tracker is unable to get any data. 
  2. Heart and breath baby monitors that use breath/pulse – Baby monitors that register the chest movement and hearts electrical activity through electrodes attached to the baby’s chest. The heart alarm is set at a heart rate of 60 beats per minute for older babies and 80 beats per minute for a young one.
  3. Oxygen baby monitors – Mostly used in hospitals and given by a baby’s doctor. 

Breathing wearable baby monitors

All breathing wearable baby monitors are not medical equipment but manufacturers put a case for it that it assists the parents to get some peace of mind as they are able to track the breathing patterns of their babies. Breathing wearable baby monitors are able to detect the baby’s breathing patterns and it is attached to the baby’s diapers or waistband. Most of the devices are made of non-toxic products such as medical grade silicon that does not affect a baby’s sensitive skin. Below are some of the breathing wearable baby monitors. 

  1. Allb Smart Baby Breathing Monitor – Allb allows you and your family to check up on your baby in real time through your smart phones and alerts you if anything is amiss.

    Primarily, allb smart baby monitor closely monitors your baby’s abdominal breathing and sends an alert to your smart phone and emits an audible alarm if your baby stops breathing. It also relays real-time respiration graph provided (Watch your baby’s breathing in real time like CCTV.). As long as there is a smart phone within 15m connected through Bluetooth LE with the allb running, the baby’s health data will be transmitted to and stored on the secure allb server. Parents and permitted connected users can check up on the baby in real time regardless of distance.
  2. Owlet Smart Sock – Owlet smart sock breathing monitor enables the parent to monitor the baby’s heart rate, oxygen levels and sleep using a proven technology.

    The Smart Sock comfortably wraps around your baby’s foot to track heart rate, oxygen levels and sleep using clinically-proven pulse optometry. The base station glows green to let you know everything is okay but notifies with lights and sounds if heart rate or oxygen levels leave preset zones. The monitor streams HD 1080p video and sound with a secure, encrypted connection to WiFi. The monitor is one of the most expensive. The smart sock comes with; Owlet Smart Sock, fabric socks (Sizes 0-18 Months), Smart Sock sensor, Base station, Charging cords, Owlet App. The app works with a smartphone but you need to download the owlet app on your phone. 
  3. MonBaby Breathing Wearable Monitor is the least expensive but not the least effective. The device is manufactured by MonBaby and comes with two color  options, white and pink. The device has to be paired with a phone in order to allow the MonBaby app receive information about the baby.

The MonBaby monitor needs to be clipped to MonBaby to the baby’s pajama and the app needs to get connected to MonBaby iphone and android app. After that, you just start monitoring your baby in real time!

Wearable Baby Monitor for Temperature and Breathing 

  1. Mimo Baby Monitor – Mimo baby monitor is a smart baby monitor that tracks an infant’s respiration, heart rate, skin temperature, sleep quality, and position through a small clip-on turtle attached to an organic cotton onesie. The clips captures the information and sends it to the smartphone giving you real time data on the activity of a child. 
    Mimo Baby Monitor for temperature


  • Easy installation


  • Low signal strength – Mimo needs a strong signal to remain connected and that can be an issue if your router is a good distance away
  • Glitch app  – The app rarely connects to the transmitter unit and it rarely gets updated
  • Distance between Turtle and base station – the Turtle monitor must be within five feet of the base station in order to work

Concerns with Wearable Baby Monitors

Data Privacy – Most device manufacturers claim that all the data is anonymized and that the data is kept safe from third parties. But they all also upload some data to their own servers, rather than keeping it strictly on your own device. The concerns however credible as we’ve had cases of hacking in the past few years. 

Fear – The data that parents and caregivers receive loads of data and they suddenly get invested in numbers that may not mean anything. The data are not necessarily co-related with certain health risks and device manufacturers are able to increase their sales by making parents think that the data they receive will enable them to avoid serious risk such as SIDS. They are therefore able to increase sales by selling fear of ‘the unknown’. In addition, several parents who use smart monitors often receive false alarms and can be very disturbing if they are thousands away from their kids.
