The FamiLock S3 Max can be unlocked using a key, touch keypad, app, or by scanning the vascular patterns underneath the skin of your palm. Palm unlocking may take a little while to get used to, but is a helpful feature if you've struggled to unlock devices with your fingerprints. The video doorbell can record 2K video with an 180 degree diagonal field of view, and both people and packages were clearly visible in our tests.
Signify is using both 2.4GHz and 5GHz Wi-Fi options on the Hue doorbell, as well as a Zigbee radio to pair with Hue lights. You can configure the Hue doorbell to automatically turn on other Hue lights when someone approaches your front door, and it also comes with a plug-in chime that can act as a siren for the Hue security system. The chime is also a requirement as the Hue doorbell won't work with any existing doorbell chime.
