Technical notes

x20 pinout

Luma x20 cameras use T568B.

Wiring the alarms

When wiring the alarms on the 420 and 820 NVRs, use adjacent COM and NO ports on the Phoenix connectors (for example, COM1 and NO1 as shown to the left).

There are four alarms available: number 1 and 3 on the top connector, and 2 and 4 on the bottom connector.
