All of our door cameras have connection cables terminated into the same 7 colour coordinated wires. 4 wires are used to connect to the monitor and then 2 of the 3 remaining wires are used to connect to an electronic door lock.
The common (COM) wire is always used along with either the normally open (NO) or normally closed (NC) wire depending on the lock type, power for the lock is separate as the Door Lock relay does not provide power output.
