Baby Monitor Frequencies

By Erika Holme

For those who want to know more about the frequencies that baby monitor is using, this will be the topic covered in this article. Broadly speaking, there are 2 types of audio baby monitor: analog and digital. Video baby monitors utilize digital.

Analog Baby Monitor

These are inexpensive and widely used in the market. It uses the 49 mHZ or 900 mHz frequency. It works like a radio frequency which carries with it some interference and static from nearby things that are using the same channel. Analog baby monitor comes with channel tuning so that you can choose the ones with the least interference.

Some allows you to choose 2.4GHz frequency which might have lesser interference.

One of the problems of analog baby monitor is if you live in close proximity with other people or if you r space has other devices like cordless phones which competing for the same frequency. If you are concerned about privacy, others are able to gain access to the frequency and hear what is being transmitted at home with your analog baby monitor.

Generally, analog baby monitors do not have strong signal strength but it is safe to be used within your home if you are not too far apart in a big house.

Digital Baby Monitor

Digital baby monitors are more popular than analog ones due to their advantages. Although it is still using 2.4GHz frequency, the signal is encrypted so that others won’t be able to hear what’s being transmitted.

While secured, interferences can still happen. There are many parents who spoke about how their digital baby monitors interfere with their wireless routers or devices like a cordless phone at home.

Most of the video baby monitors are using digital frequency.

DECT Digital Baby Monitors

It seems that the only way to have an encrypted frequency without interferences is to use DECT typed digital baby monitors. These baby monitors use 1.9GHz frequency which is newer and less commonly used.

Nowadays, baby monitors have developed a sensitive microphone that picks up noise from your baby with noise-canceling abilities.

Safety Concerns

We have to consider the harmfulness of pulsed signals, especially when we are dealing with baby products which might be in close proximity to babies. Although digital baby monitors emit stronger signals as compared to audio baby monitors, there has been a lack of evidence in regard to the harmful effects of signals.

Still, if you are concerned with EMF exposure, the recent baby monitors have quality cameras and camera functions to monitor your baby without being too close. So you can play safe by placing the device further away, which is also helpful as it avoids strangulation risks by having cables far away from your baby.

Final Thoughts

Nowadays, the baby monitors are packed with tons of features and they are all digital video baby monitors. It is hard to go back to using audio and analog baby monitors without all these functions. Unless you have a specific need for a simpler audio setup, look towards using digital and DECT baby monitors.

Devices are here to stay in our lives so what we can do is to put in safety measures like placing baby monitors away from our little ones to protect them.
