Icon

Function

1～16

ALARM1～ALARM16. The alarm becomes activated in the low level.

NO1 C1，NO2 C2，NO3 C3，NO4 C4

Four NO activation output groups. (On-off button).

NO5 C5 NC5

One NO/NC activation output group. (On-off button).

CTRL 12V

Control power output. Disable power output when alarm is canceled. Current is 500mA.

＋12V

Rated current output. Current is 500mA.

GND

A/B

485 communication port. They are used to control devices such as PTZ. Please parallel connect 120TΩ between A/B cables if there are too many PTZ decoders.

Note

  • Different models support different alarm input ports. Please refer to the specifications sheet for detailed information.
  • Slight difference may be found on the alarm port layout.

Alarm input port

Connect the positive end (+) of the alarm input device to the alarm input port (ALARM IN 1～16) of the NVR. Connect the negative end (-) of the alarm input device to the ground end (
