Alarm Input
Connect the cable to sensors such as infrared 
sensors, door sensors, metal sensors and 
manual switches.
䡵 Input Requirements
● Non-voltage relay NPN open collector input
● Polarity of input detection can be selected 
using a software
● Make/break (500 ms and above)
● Circuit current of 1 mA during low-level input
● Applied voltage of 3.3 V during high-level 
input
Alarm output
Connect to alarm devices such as alarm, 
indicator, light or buzzer.
䡵 Output Requirements
● NPN open collector output equivalent (Refer 
to the INSTRUCTIONS (Setting) on 
procedures to set the output logic. )
● Allowable applied voltage: DC 12 V and 
below
● Allowable inflow current: 50 mA
● Momentary (100 ms to 5000 ms) output
(Refer to [INSTRUCTIONS (Setting)] for 
procedures to set the time. )
Note:
                                                          
● Connect the GND cable of the camera to the 
GND terminal of the alarm device.
