At over $200, are advanced audio/video monitoring systems with multiple cameras and receivers with large screens, as well as the ability to connect to several mobile devices. While they are loaded with features, it’s important to look closely at the audio and video quality. Expensive monitors are just as susceptible to interference as inexpensive ones.
Encrypted Wireless Communications: Here's something creepy and strange - there are reports of people tapping into even the best baby monitors and getting some bizarre pleasure from watching your baby sleep or watching you feed the baby in the middle of the night. A few of the manufacturers have included wireless encryption on their systems to make this much less likely.
BabyPing also works over 3G/4G and Wi-Fi networks. With easy set-up directly on your mobile device (no computer necessary), the BabyPing app enables parents to be one tap away from seeing and hearing what their baby is up to. The unit's Smart Filter ensures that all you hear is the baby, not background noise in the house. There is no functionality to talk to the baby through the app, but what differentiates BabyPing is its password-protected double-layer encrypted security, which gives parents the ability to give access to only those they wish to. BabyPing offers night vision to give parents full visibility into the dark nursery without disturbing the sleeping baby.
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.
