Knok Video Doorbell


Momentum KNOK is a video doorbell that alerts you of visitors at your front door from anywhere. The Knok is equipped with a HD 1080P resolution camera and infrared LEDs to see clearly during day or night. Motion detection alerts and recordings are captured through a customizable, 130 degree view angle motion zone, and you can see a live feed from your camera with the easy-to-use Momentum app. Knok also comes with two-way communication, remote siren, interchangeable color case, and included mounting kit, and can be wired to your existing chime and transformer.
