•
Audio Out
Connect an amplifier to this port (line out). This device
does not feature a built-in audio amplifier unit and
therefore requires the user to purchase a separate
speaker system with a built-in amplifier.
•
Audio In
Connect an audio source to this port (line in). A built-
in microphone is featured on the front.
•
Alarm In / Out
-
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.
-
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 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.
•
When switching over from 12 VDC to PoE as the
power source, the system will be rebooted once the
power adapter is disconnected.
•
Ground the power port's frame ground terminal
before use.
•
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.
