Baby monitors may have a visible signal as well as repeating the sound. This is often in the form of a set of lights to indicate the noise level, allowing the device to be used when it is inappropriate or impractical for the receiver to play the sound. Other monitors have a vibrating alert on the receiver making it particularly useful for people with hearing difficulties.
For roughly a third of the price of our pick, the VTech is far more affordable. Losing video is a major sacrifice, of course, and we’re certain most parents looking for a first monitor will prefer being able to do a visual check-in on a baby. Budget advantages aside, we could see this being best for parents of toddlers who are considering replacing a failing monitor, and who know they will likely use a monitor only at night as a way to hear a kid crying out from a distant bedroom. Many reviewers have also found it useful as a way for adults to communicate, especially for caretakers who need to be able to hear when adults with mobility or medical issues need help in another room.
Wireless encryption: This ensures that no one else can tap into your monitor’s “feed” and see what’s going on in your house. WiFi-enabled monitors are great for portability and range, but may be more susceptible to hacking. If you go this route, be sure to secure your home wireless network and keep the monitor’s firmware updated. Otherwise look for digital monitors with a 2.4 GHz FHSS wireless transmission.
