Feature 1 Remote Video Calls: Through an APP and mobile network, when a visitor presses the doorbell, a notification will be pushed to your phone. You can then enter the mobile video call interface to remotely view the situation at your doorstep in real time. 2 High Fidelity Microphone: With a two way talk design and a high power speaker paired with a highly sensitive microphone, the visual call at your front door is really clear. It supports adjusting the volume to avoid disturbing your family. 3 Wide Angle Lens: The wide angle lens records the entire scene in front of your door, leaving no "security blind spots" and allowing you to clearly see multiple visitors. 4 HD Camera: The high definition camera can record 1080P level HD videos, providing rich details and allowing you to see the facial features of the visitors clearly. 5 Day and Night Camera: The built in high power infrared night vision light, combined with an ICR infrared filter, automatically switches between day and night modes. Even in pitch black environments, you can see and record clear images.Item Type: Wireless Doorbell CameraMaterial: ABS, metalWeight: Approx. 141g/5.0ozColor: BlackLens Angle: 80 degreeNumber of Infrared Lights: 4Night Vision Distance: 5 to 10 metersConnection Method: Mobile phone APPPickup Distance: 5 metersStorage: Cloud storageDoorbell Camera Battery Type: Lithium ion batteryDoorbell Camera Battery Capacity: 800mAh (shipped with built in battery)Charging Port Type: Type CAPP Name: KementWiFi Version: 2.4GHZMobile Phone System Support: for Android 4.3 or for IOS 9.0 or above versionReceiving Port: USB Package List1 x Doorbell Camera1 x Receiver1 x Adhesive Backing1 x Specification1 x Charging Cable2 x Big Screw1 x Small Screw2 x Expansion Tube
