The best monitor for sound in our tests is the Philips Avent SCD630, with a score of 8 of 10. This monitor has the best sound activation and background cancellation features in the group, and while the sound is bright, it is also clear without an echo. Most of the competition earned 4s and 5s for sound, with all of the Wi-Fi monitors only earning 4s. It seems that no matter how good your parent device might be, the Wi-Fi cameras struggle for the most part to transmit clear sound with good sound features.
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.
