Alarm Input/Output Terminal Connection

Connect the alarm input/output terminals with external devices, such as a sensor or buzzer. Plug/Unplug the cable while pressing the button as shown in the diagram below.

Cable to use

●Shielded cable

●Length of 50 m or shorter

Caution:

●Noises from an external source may cause the camera to malfunction even when the cable used is within 50 m. In this case, move the cable away from the noise source.

Alarm Input Terminal

Connect this terminal to sensor devices, such as an infrared sensor, door sensor, metal sensor or manual switch.

Input requirements

●No-voltage relay NPN open collector input

●Polarity of input detection can be selected using a software

●Make/Break (500 ms and above)

●Circuit current at low level: 1 mA

●Applied voltage at high level: 3.3 V

Alarm Output Terminal

Connect this terminal to annunciating devices, such as annunciators, indicators, lights, or buzzers.

Output requirements

●Equivalent to NPN open collector output (Set the output logic using the Internet Explorer)

●Allowable applied voltage: DC12 V and below

●Allowable inflow current: 50 mA

●Momentary (100 ms - 5000 ms) output (Set time using the Internet Explorer (A Page 46))
