Alarm in
Connect an alarm-in device to this port. Connect a
mechanical or electrical switch to the IN and GND
(ground) connectors. 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.
•
Alarm Out
If the camera is
DC-T1234WR
, connect an alarm out
device's mechanical or electrical switch to the OUT+
and the OUT- connectors. (Supported Types: NO
(Normally Open), Electrical Specs: 0.3A sync current
at 125 VAC, 1A sync current at 30 VDC)
If the camera is
DC-T1233WHR
, it is the BJT (Bipolar
Junction Transistor) - open collector output. If the
voltage and current exceed the specification limit
(max. load: 50mA, max. voltage: 30VDC), 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 parallerl with the load
for protection. Otherwise, the product could be
damaged.

•
Check your local laws and regulations on making
video or audio recordings. The user will be held
liable for any violation of the law. (Article 25-5
of the Personal Information Protection Act:
Operators of image data processing devices
may not operate such devices for purposes
other than as originally intended during device
installation, place such devices at locations other
than as originally intended, or use such devices
to record audio.)
•
When switching over from 12 VDC to PoE as the
power source, the system will be rebooted once
the power adapter is disconnected.
•
Organize the power cable so that it will not
cause people to trip over or become damaged
from chairs, cabinets, desks, and other objects
in the vicinity. Do not run the power cable
underneath carpet or a rug or plug the cable
into a power outlet shared by a number of other
devices.
•
Wrap the camera-end of the network cable twice
around the provided ferrite core (28A2024-0A2,
Laird Technologies) to subdue electromagnetic
wave generation.

•
The network connector is not designed to be
connected directly with cable or wire intended
for outdoor use.
