Most of the parents fail to understand their baby’s observation and basic functions of baby monitor frequencies. Baby monitors function on a specific frequency. They transmit and receive the signals on a frequency, which is more of a defined network. Basically, they are radio transmitters that work on a fixed frequency. If there is a slightly different frequency, the camera or baby unit might not send and receive signals from the parent unit.
That is why you should be careful when setting the frequency of your baby monitor. We understand that it can be difficult to understand the monitor frequencies. That is why we came up with this article to help you understand them and know how they work. That being said, here is detailed information on frequencies of a baby monitor.

Patterns of Frequencies for a Baby Monitor
Well, not all baby monitors function on a fixed frequency. Instead, only digital and analog units are the ones that transmit and receive signals through a frequency. The analog monitors use 49MHz or 900MHz radio frequencies, while the digital monitors use a default, 2.4GHz frequency. These frequencies can be adjusted according to stay safe and prevent hacking.
The Range of Monitor Frequencies
The baby monitor range can be an issue if the house is too big or if you hang out of the house too often. Most baby monitors come with limited coverage, which means that the frequency will also be affected. The frequency will remain the same, regardless of the range, but it will become weaker.
Frequencies Used in Baby Monitors
Baby monitors come in different categories, but most monitors on the market use the 2.4GHz frequency. This is also the same frequency used by most modern devices including Bluetooth headsets and wireless routers.
What Technologies Are Used on Baby Monitor?
Due to the vulnerability and openness of the monitor frequencies, manufacturers and technology experts introduced unique technologies that prevent hacking and eavesdropping. Technically, there are two main technologies used on these frequencies. They include the following;
Digitally Enhanced Cordless Telecommunications(DECT)technology.
This is a technology that utilizes a unique 1.9GHz frequency to minimize background interference. It helps to prevent the interference of other devices like cordless phones.
Frequency Hopping Spread Spectrum(FHSS).
This supposedly the best technology any baby monitor should have, especially if you are concerned about your privacy. With this technology, your digital baby monitor can switch signals automatically to prevent eavesdropping. If you are going for a digital baby monitor, check that it features the FHSS technology.
These technologies help to make your baby monitor not only perform better but also make them more secure. They will be less susceptible to a hack, thanks to the FHSS technology.
Baby Monitor Frequency Interference
Most commonly, modern devices will easily interfere with the frequencies of the baby monitor. The baby monitor can be affected if it is near a device like a cordless phone. If the monitor is near the cordless phone, you will experience some static, irritating noises. There can also be cross-talking in the event.
In this case, a 1.9GHz frequency band would be good enough for the baby monitor. However, the 1.9GHz frequency will only work for voice-only procedures. The DECT technology will help to make the audio signals clear without background interference.
It should also be noted that there only be interference if the frequency of the baby monitor and the other device are similar.
How To Fix Frequency Interference
The first option is to ensure that the baby monitor has the DECT technology. If not, you should try to fix the interference manually. First off, check if there is any device near the baby monitor, which might affect the frequency of the monitor.
Keep the devices away from the baby and parent unit, or switch them off when they are not in use. You should also try to adjust the frequency manually.
Tips on Controlling and Preventing Baby Monitor Interference
There are various ways you can control the interference of your baby monitors. Here is a guide to help you;
• Check your WiFi frequency to ensure it is not on the same frequency as the baby monitor
• Modify the channel to make it unique
• Turn on the baby monitor first to prevent interference of other devices
• Maintain a safe and secure distance
• Choose a digital baby monitor that has the DECT technology
It is all about choosing a baby monitor that has the right technology/features to enhance the signals transmitted and also keep the frequency safe and secure. Always ensure that you test the monitor before you decide to buy it.
