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.
The Philips Avent SCD630 is the easiest to use dedicated option with a score of 8 of 10. This monitor is a plug and play that pairs the camera and parent unit by itself. The parent unit has very few buttons, with the most frequently used buttons are on the face of the unit. The menu options are relatively intuitive with not much chance of taking a wrong turn or getting buried in a file menu system you can't get out of. The menu could be easier to use, but we think most parents will stick to the buttons on the front of the unit after a few weeks of regular use. The Levana Lila has fewer features and is even easier to use, thanks to a lack of convoluted menu options.
Notifications and alerts work by sending a message or email to your device when motion or sound has occurred. This feature is only found in the Wi-Fi monitors, and isn't the best feature for baby because it comes after the fact (sometimes up to 30 min or more after), it does not offer details of the type of sound or motion detected, and could get annoying with useless and excessive messages being sent. In the end, we prefer sound activation over notifications and feel that alerts and notifications aren't all that useful for keeping tabs on your 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.
