Alarm I/O
-
Out
: It is the BJT (Bipolar Junction Transistor) -
open collector output. If the voltage and current
exceed the specification limit (Max load: 30mA,
Max Voltage: 5VDC), the product could be
damaged. When connecting the device which
exceeds the specification limit, refer to the picture
(circuit) below.
If used with an external inductive load (e.g.
relay), a diode must be connected in parallel
with the load for protection. Otherwise, the
product could be damaged.
-
In
: Connect an alarm-in device to this port.
(Mechanism: Choose between an NC (Normally
Closed) type or an NO (Normally Open) type)
Connect a mechanical or electrical switch to the
alarm in port and the GND (ground) connector.
Alarm in range is 0V to 5V. In order to detect alarm
input from an electrical switch, the signal must be
higher than 4.3V from an NC switch or less than
0.3V from an NO switch and must last for longer
than 0.5 seconds.

Factory Reset Switch
Restores the camera's default factory settings. For
more information, refer to the
When inserting an , audio in/out, or RS485 connector,
hold down the button and push the connector in
through the exposed hole. Release the button and
then gently pull on the wire to ensure a secure
connection. To disconnect the cable, press down on
the button again and pull the cable out.
•
Check your local laws and regulations on making
video or audio recordings. The user will be held
liable for any violation of the law.
•
The network connector is not designed to be
connected directly with cable or wire intended for
outdoor use.
