And at night, the camera’s IR night vision function will automatically activate, with its IR LEDs that allow you to see everything in crystal clear detail even in total darkness. This door monitoring camera ensures that you’ll have the peace of mind even when you’re away from home. Not only will you be able to get a good view of your front door from your mobile device, you can also hear and talk to whoever’s at the door, no matter where you are. That’s all thanks to the system’s real time two way audio feature, with its built in microphone and speaker. The VueBell WiFi HD Camera Video Doorbell also comes built with a motion sensor technology called Smart Guard Function that triggers an alert and sends real time push notifications, along with a snapshot, to your smartphone or tablet. This is triggered whenever motion is detected or when someone rings the doorbell or have not pressed the button.
