All of the products in our review have features for convenience and overall function, but some also offer features for fun or additional information. All of the products have night vision with sensors for automatic adjustment with light changes, and all offer 2-way communication with baby through the camera. Some of them come with lullabies, and others have nifty temperature and humidity sensors. Overall, whatever you might be looking for, or never knew existed but now want, can probably be found in the products we tested.
There are two basic types: audio and video/audio. Some are analog, others are digital. All monitors operate within a selected radio frequency band to send sound from a baby's room to a receiver in another room. Each monitor consists of a transmitter (the child/nursery unit) and one or more receivers. Prices range from about $25 to $150 for audio monitors and about $80 to $300 for audio/video monitors.
The iBaby M6S Wi-Fi is the easiest Wi-Fi monitor to setup and use with a score of 9 of 10. The Nest Cam Indoor Wi-Fi camera is hot on its heels with an 8. Both options walk users through the setup process step-by-step and have intuitive menus that will seem familiar to even the most novice user who is familiar with a smartphone. Both options come with a quick start guide that will have you up and watching your baby in no time.
A word of caution about extremely cheap baby video monitors (we're talking devices that cost less than $50): they're not known for their security and can be hacked. Be sure to always change the default password of any connected device you purchase. You can also protect yourself by sticking to known vendors who post frequent firmware updates and have easy-to-reach customer support.
