3.1 Cameras
All of the DoorKnox 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.

3.2 Monitors
Every monitor is supplied with 5x 4 wire y-leads, 1x 2 wire y-lead and 1x 3 wire y-
lead.
The 4 wire y-leads are terminated into 4 pin plugs which are simply inserted into the
sockets on the rear of the monitor. These are used for connecting door cameras,
auxiliary cameras and auxiliary monitors, the 4 wires are colour co-ordinated to
match the 4 wires from the door camera.
The 2 wire y-lead is terminated with a 2 pin plug and is used as the TV out for
connecting the door monitor to a TV monitor or DVR.
The 3 wire y-lead is terminated for the local relay plug and is used to unlock a local
relay like a door release local to the monitor.
3.3 Powering Cameras
Door cameras and auxiliary cameras can be powered in two ways, either locally or
via the main monitor.
The DoorKnox monitors can supply a 12V DC output to any of the four cameras but
can only supply a maximum of 400mA across all outputs.
To power a camera locally connect the Audio (white) and Video (yellow) to the door
monitor, the GND (black) to the PSU and the door monitor and then the 12V DC (red)
to the PSU only.
3.4 Powering Monitors
Door monitors are supplied with a 12V DC 2A plug-in PSU that terminates into a 2
pin plug which slots into the rear of the monitor.

3.5 Cable Runs
The maximum achievable cable run is limited by the voltage drop in the chosen cable
and also the quality of the video cable which can cause signal loss and interference.
Resistance differs depending on the cable used and the higher the resistance the
more the voltage drops hence the shorter cable run achievable.
It is recommended to use one of three types of cable, PTZ combo cable sometimes
known as RG59+4, CAT5+2 cable or 4 core cable with 0.3mm2 cores.
Below shows the maximum recommended cable run for each cable type. Cable runs
exceeding the stated maximum run are at risk of issues caused by voltage drop and
non performance of equipment.
