External Alarm In/Out Connection and RS485 connections

This DVR has 4 alarm inputs with two connections for ground and one output alarm.

Note that if you remove the alarm input terminal connection block, the connections are

detailed on the DVR case.

The RS485 connections for controlling up to 4 x PTZ cameras must be connected to the T+

and T- terminal block as shown above.

1 x Alarm Output Connection

Please note the usage of jumper JJ1. If you use DC, either connection is okay. It is

suggested that you use 12vDC at less than 1 Amp. If you use AC, ensure the jumper is

opened. There is a jumper on the mainboard corresponding with the alarm output. The

default is closed.

WARNING: IF YOU USE AC FOR RELAY OUTPUT, ENSURE THE JUMPER IS

OPENED.
