•
Network Port
Connect a network cable with an RJ-45 connector to
this port. If using a PoE switch, you can supply power
to the camera using an ethernet cable. For more
information on PoE switch use, refer to the switch
manufacturer's operation manual. You can configure,
manage, and upgrade this camera and monitor its
images from a remote computer over the network.
For more information on network connection setup,
refer to the
INIT operation manual
.
•
Video Out (BNC)
Connect the monitor. Use these ports for previewing
video and not monitoring video.
• Power In
Connect to the power adapter (12 VDC).
•
FGND (Frame Ground)
Used to ground the device.
• Audio In
Connect an audio source to this port. (line in)
•
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.
•
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
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.
