The features we focused on were those we thought either increased the performance of the monitor or made it more user-friendly for parents and increased the odds of getting good quality sleep. We looked for monitors that have sound activation that keeps the parent unit quiet when the baby isn't crying, so parents can potentially fall asleep faster because they don't have to listen to white noise. Some of the monitors were so loud, even at low volumes, that the white noise might keep light sleeping parents awake; this defeats the purpose of having a video product to begin with. We also liked the models with screens that automatically "wake" and/or go to sleep.
So we recommend choosing a baby monitor that uses a different frequency band from your cordless phone and other wireless products in your home. The band that your cordless phone operates on should be printed somewhere on it. Remember that interference can vary widely depending on where you live, the electronic devices you have at home, and the ones your neighbors have. If, for example, you have a 2.4 GHz wireless product, such as an older cordless phone, choose a baby monitor that doesn't operate on the 2.4 GHz frequency band. People with newer phones that use DECT will have fewer issues with interference.
However, the Baby Delight’s biggest flaw is one of technicality: Its button sensor is just large enough to avoid being labeled as a choking hazard, but it doesn’t leave a lot of room for error. In fact, the button does become a choking risk after your child is 3 years old, and the new parents we spoke to felt uneasy about using it after 12 months just to be safe. Still, if you’re only interested in monitoring movements for the first few months, the Baby Delight is a more user-friendly alternative to the Angelcare.
The Samsung's display, at 5 inches, is among the largest and crispest you'll find on a baby monitor. However, the touchscreen response is sluggish, which makes it difficult to smoothly pan or tilt the camera. And when you pull up the menu, you lose the video and the audio output—that's a weakness compared with our pick, which continues to display video and play sound while navigating menu functions.
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.
