The audio quality is excellent, thanks to VTech's use of DECT 6.0, so you shouldn't hear any interference, static, or echoing when you listen in on your baby. Since the monitor uses a special frequency to relay the signal from the monitor in your baby's room to the parental unit, everything is encrypted and secure. No one but you will hear your baby.
Electromagnetic fields (EMF), or dirty electricity, is something we think needs to be discussed when talking about wireless baby monitors. Given that all wireless devices give off some level of EMF, we feel it would be negligent not to discuss the potential for possible health risks associated with the kind of radiation emitted by wireless products. While the jury is still out, and studies being done are not conclusive yet, there is enough evidence that EMF might potentially cause health problems that we feel it is better to be cautious when it comes to children's exposure than to ignore the possibilities.
This baby monitor works very well. It has a very small footprint compared to my crib, seen in the picture. The night vision is clear and automatically turns on. The music it plays is very soothing and I can toggle it on and off easily. The range on it is far enough that I can be anywhere in my house and have good reception. The screen is also bright and has a very clear picture. The monitor also lasts a fair a mount of time on battery. It is not HD but for the price it works very well.
After testing more than half-a-dozen mounted cameras that beam live video from a nursery, the best baby monitor we've tested is Netgear's Arlo Baby. Netgear's baby monitor packs in a number of must-have features such as clear 1080p video, two-way audio and a host of sensors. Everything's easily accessible from a well-organized mobile app that puts the Arlo Baby's controls at your fingertips.
If you'd like the flexibility of having a dedicated handheld monitor for use in the home, while still being able to rely on your Internet network on a mobile device, the Peek Plus Internet Monitor System is worth looking at. The Peek Plus connects directly to your home wireless network for instant access. You can begin viewing the stream on the included handheld monitor or via a dedicated Internet browser or complementary smartphone app (for iOS, Android and Blackberry), or both. The secure Internet page of your baby's video stream gives family and friends the ability to look in on your baby as well.
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.
