Connect the alarm input/output cables with
external devices such as a sensor, buzzer, etc.
Note：
● Noises from an external source may cause
malfunctions even when the cable used is
shorter than 50 m. In this case, use a
shielded cable or move the cable away from
the noise source.
Alarm Input
Connect this terminal to sensor devices, such as
an infrared sensor, door sensor, metal sensor,
manual switch, etc.
Ⅵ 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: 0.3 mA
● Applied voltage at high level: 3.3 V
Alarm Output
Connect this terminal to annunciating devices, such
as annunciators, indicators, lights, buzzers, etc.
Ⅵ Output requirements
● Equivalent to NPN open collector output (Set
the output put logic via the Internet Explorer)
● Allowable applied voltage: DC12 V and below
● Allowable inflow current: 50 mA
● Momentary (100 ms to 5000 ms) output
(Set time via the Internet Explorer )
Note：
● Connect the GND cable of this camera to the
GND of the annunciating device.
