Digital Door Viewer with Bell
Mul-T-Lock’s Digital Door Viewer is a fine complement to a high security locking system. This informative device with bell gives notice of a guest’s arrival as well as a snapshot of the visitor. When visitors press the door bell button on the door viewer camera, the door bell will ring inside of the room while the screen inside the door will turn on automatically to show the outside images and will last for 20 seconds before turning itself off. Also as the door bell is pressed, the camera will automatically take a photo of the visitors and the photo will be stored in the TF card in case the host is out, so as to check the visitors identity or to use the information for security purposes.
