Monitor DoorKnox

DoorKnox is a low-cost but feature packed video door entry system. In its basic format it consists of 1 monitor located inside a property and a camera with a “call-button” on the outside of the property. When someone presses the call-button it chimes the monitor and the person who is inside the property can see the visitor. A two-way intercom then allows the occupier to chat to the visitor and if they choose to they can then remotely operate a door release to let the visitor come in. As a stand-alone system the SD card will record 2 minutes or 80 still images every time the call-button is activated, which can be played after the event directly from the monitor or from a PC.
