From 1937 to the 1960s, analog baby monitors with simplex communication mode (one-way) dominated the baby monitor industry. The digital processing technology which was discovered in 1965 paved the way for digital encrypted communication. More than 90% of the monitors in the market in 2019 are digital but about 10% of baby monitors still use analog transmission technology to transfer audio signals from the baby unit to the parent unit. We checked the market and could not find an analog video baby monitor.
What is Analog Baby Monitor
Analog baby monitors are devices that transmit audio signals using lower frequency bands using non-linear, unencrypted signals. Analog baby monitors utilize 49 MHz to around 900 MHz frequency bands which is lower than digital baby monitors’ frequency bands which range from 1.8 GHz to 5 GHz. Most digital baby monitors rely on 1.9 GHz to 2.4 GHz but some of the latest brands such as Nanit also rely on 5 GHz frequency band that has less interference.
Analog Vs Digital Baby Monitor
The table below shows the difference between Analog and Digital baby monitors. The table below will assist you to decide whether you can go for an analog or digital baby monitor in 2020.
|Analog Baby Monitor||Digital Baby Monitor|
|Unencrypted communication signals||Encrypted communication signals|
|Lower frequency band from 24 MHz to 900 MHz||Higher frequency band from 1900 MHz to 5000 MHz.|
|Has a lot of interference and noise is not very clear||Limited interference|
|Limited range||Longer range|
|Limited channels||Several channels|
Are analog baby monitors safe
Analog baby monitors use lower frequency bands from 24 MHz to 900 MHz to transmit signals from the baby unit to the parent unit. Graco baby monitors have been leading the way and have advocated making the case that analog baby monitors are safe and we sought to investigate this claim here at 10BabyGear.
Analog does not have several channels and are not encrypted. Another question we always get is whether analog baby monitors are safer than digital baby monitors.
Analog baby monitor radiation
Analog baby monitors use radio frequency to transmit signals. It, therefore, emits radiation as it is a wireless communication device.
Philips Avent analog baby monitor
Philips Avent Analog baby monitor, SCD485/01 is an analog baby monitor manufactured by Philips Avent. However, this analog baby monitor by Philips is no longer available as it has been discontinued. By the time we published this article in 2019, a few of these low-frequency analog baby monitors were still available on Amazon and you can check it today here.

Safety 1st Crystal Clear Audio Monitor, White
Safety 1st analog baby monitor challenges the Philips Avent analog baby monitor. Similar to VTech audio baby monitors, Safety 1st Analog baby monitor, it experiences interference.
It has a 600 ft. range and uses the 49 MHz frequency band, a band higher than Philips Avent’s analog baby monitor.
Unlike the Safety 1st Sure Glow audio baby monitor below, this brand uses 2 channels to minimize interference and comes with an audio jack for listening w/earphones.
This Safety 1st’s 49 MHz analog monitor is also among the few baby monitor with an audio jack and earphones. In addition, it has a convertible belt clip/carry loop.
Safety 1st Sure Glow Audio Monitor
Safety 1st Sure Glow in another analog baby monitor brand by Safety 1st. It uses the 49 MHz frequency and has a range of 600 ft. which is average that of most non-wifi baby monitors.
In case you miss the parent unit, you can use the pager as the parent unit as they use the same frequency. To assist you to easily use this baby monitor, power and low battery indicators and volume controls.
The table below summarizes the details of this analog monitor.
|Name||Safety 1st Sure Glow Audio Monitor|
