This articles discusses how minimize baby monitor interference to achieve the best possible sound qualiy.
What is Interference?
It is simply a clash of frequencies between two or more devices emitting similar frequencies.
Some of the most common wireless devices found in the home include:
Cordless telephones, Wireless toys, Computer networks, Bluetooth devices, Microwave oven
The interference may be in the form of static, buzzing or high pitched sounds. If you are using a digital monitor, the visual image of baby and surrounding elements may be fuzzy and blurred. It’s not uncommon for monitors to pick up the neighbor’s talking on their cordless phones. And if your monitor can hear them then chances are good that someone else’s monitor can hear your conversations.
When choosing the radio frequency for a wireless baby monitor, consider these factors:
- Signal range can be affected by obstructions within the home and interference from other electronic devices.
- Electronics using different frequencies will not interfere with each other.
- Lower frequencies, such as 900 MHz, can better penetrate solid objects, such as household walls, glass, brick, plastic, and trees.
- The 2.4 GHz bandwidth is widely used in other electronic devices like cordless phones and thus more susceptible to interference.
- The newer, less-crowded 1.9 GHz frequency virtually eliminates interference with other electronics, since they typically operate on different frequencies.
Enjoy Privacy With Zero Interference Using DECT Technology
A DECT ((Digital Enhanced Cordless Telecommunication) baby monitor will provide a crystal clear sound and is immune to household appliance interference as well as interference from other baby monitors. They have the ability to detect interference in a split second and automatically switch channel without you even noticing, within a blink of an eye.
You can be assured of a secure, private connection and crystal clear sound with DECT. Zero interference is achieved by automatic channel switching upon detection of any interference.

The Philips Avent SCD520 builds upon the basic model with the addition of a parent unit digital screen; temperature sensor; soothing lullabies and nightlight. It has a list price of $149.99.
4 Tips For Resolving Interference Problems
- All of the wireless equipment in your home should have the channels adjusted. To do this, simply locate the word “channel” on the cordless gadget, and select the one you want. The device doesn’t have to be in close proximity to the baby monitor in order to cause problems, therefore, adjusting the channels of all devices is recommended.
- Know that most cordless phones operate on the 2.4GHz frequency band and the cell phone on the 0.8GHz to 1.9GHz.These channels are not as commonly utilized as the 2.4GHz frequency band, making them less prone to interference. If your home’s cordless phone is the problem, try selecting a channel of either the 0.9 Ghz or 6 Ghz channel.
- Shut down any device that could be interfering with it. The list of possible offenders includes computer routers and cordless phones. Next, turn the baby monitor on, and then wait a few moments before turning all of the other devices back on. Doing this will allow the baby monitor to enjoy the clearest signal and avoid any interference problems.
- If interference continues to be a problem you can try moving your wireless devices into new locations, further away from the monitor. You should try to keep all of your wireless devices as far apart as you can. Think about the room in which you’ll mostly be keeping an eye on your child, and move any other wireless devices there to a room which is not as frequently occupied.
If all else fails and the sound quality is still less that desired from analog baby monitor, try getting a digital one instead to minimize baby monitor interference.
