What is DECT Baby Monitor?

DECT baby monitors are audio baby monitors and video baby monitors that rely on 1.9 GHz frequency and use Digital Enhanced Cordless Telecommunications(DECT) technology. This technology is principally known for cordless phones but major baby monitor brands such as Panasonic and VTech rely on this technology for their long-range baby monitors.

As you may have seen above, DECT stands for Digital Enhanced Cordless Communications and was initially rolled out in Europe following the delay in radio frequency regulations in the US. Unlike other digital baby monitors that use 2.4 GHz frequency, DECT baby monitors use an uncommon frequency making it experiences less interference with other gadgets. This is the principal reason why DECT was chosen for telecommunication.

The biggest challenge faced when using a 2.4 GHz baby monitor and an analog baby monitor is the interference of the signal. DECT baby monitors overcome this challenge by using an uncommon 1.9 GHz frequency band for audio baby monitors.

DECT Baby Monitor Safety: Can it be hacked?

Wondering whether DECT baby monitors are safe?

DECT baby monitors are not hack-proof but similar to FHSS baby monitors, they are almost impossible to hack as they rely on their own network to transmit the signal from the baby unit to the parent unit.

A DECT baby monitor is very similar to a DECT phone, the cordless phone. In fact, the audio transfer is very similar. DECT baby monitors have a superior sound quality and do not suffer from interference caused by other wireless networks. DECT 6.0 uses a lower frequency band, 1.9 GHz which has low electromagnetic radiations.

DECT 6.0 technology is widespread in Europe and has been in use since 1987. North America licensed the DECT 6.0 in 2005 after sufficient proof that it has reliable transmission range and less interference. Like other digital baby monitors, the DECT baby monitors are not emission-free.

VTech has developed several products that use DECT technology as the company has emphasized its focus on sound clarity and less interference in their baby monitors. The DECT baby monitors are considered safe as they do not emit radiations as wireless baby monitors that use 2.4 GHz band, essentially all wifi-baby monitors.

Features of DECT Baby Monitors

1. Continuous Broadcast – The DECT baby monitors continuously transmit signal from the baby unit to the parent unit. As the baby monitor transmits the signal, it emits electromagnetic radiations and parents who are concerned with radiations, DECT baby monitors are not the best as they emit a lot of radiation. You can opt for a baby monitor that only transmits the signal when a particular activity is reached (movement or particular sound level). You can opt for Voice-Activated (VOX) Baby Monitors

2. Minimal Interference – DECT baby monitors became popular mainly because it has minimal interference from other devices. The signal is transmitted via several channels and the handover of the signal to the parent unit is done automatically. Channels with less interference are the handover channels and the channel selections feature enables multi-channel DECT monitor to avoid channels with interference.

3. Security & Encryption– When pairing the baby and the parent units, a secret subscription pin is required. The unique code which is entered once minimizes the risk of misuse. In addition, the parent unit needs to be close to the baby monitor unit to establish connections. The location limits the vulnerability of the baby monitor and since the signal is not transmitted over the internet, there is a limited possibility of hacking. DECT technology encrypts data in transit and an authentication process is required. Both the receiving and the transmitting units of the baby monitor have to decipher the information that would unlock the data.

DECT Baby Monitor Radiation

There has been a lot of push to regulate and perhaps phase out DECT baby monitors as experts claim that it emits more EMF radiation compared to its peers, FHSS baby monitors. DECT baby monitor transmits a burst of radiations every time it is powered and a comparison showed that DECT devices including DECT phones can be dangerous as they expose high people with high EMF radiation. You can read more about baby monitor radiation and how to be safe. The article has more details on DECT technology baby monitor dangers.

In our 2019 list of best non-wifi baby monitors, we did not include any DECT baby monitor as I fully agree with arguments against using this DECT technology as it emits high EMF radiation. All the best non-wifi baby monitors are therefore FHSS baby monitors or non-DECT baby monitors.

DECT Baby Monitor FAQs

What is DECT technology baby monitors

DECT technology baby monitors are baby monitors that use 1.9 GHz frequency to facilitate the transfer of signals from the baby unit to the parent unit. DECT baby monitors are preferred as they have less interference compared to other baby monitors that use 2.4GHz frequency band such as FHSS baby monitors.

Can DECT baby monitors be hacked

DECT baby monitors do not rely on the internet but a spread spectrum technology also called DECT 6.0 in North America. DECT’s signal has a limited range as it does not rely on long-range Wifi technology in the 2.4GHz frequency. DECT baby monitors cannot be hacked as the DECT spread-spectrum infrastructure relies on a reliable local-area connectivity and is not prone to hacking.

Which DECT baby monitors have temperature sensor

Philips Avent 630 is a DECT baby monitor that comes with a temperature sensor and you can rely on it to alert you when the temperature in the baby’s room is out of the set, normal range. Philips Avent SCD 630 has a camera with an inbuilt temperature sensor.
