Phoenix TechnoBell 101 is a smart Video DoorBell that comes with a free Mobile App.
The doorbell connects to your Home WiFi or wired LAN and achieves 2-way intercom
with your mobile phone, via the app. Whenever a visitor presses your doorbell, you
get a video call on your mobile phone. On accepting the call, you can see the live-video
of your visitor and talk to him/her from your smart phone. No matter where you are,
you can check who is at your door.
