2.4 Connections
• Connecting the Network
Connect a standard RJ-45 cable to the network port of the camera. Generally a crossover cable
is used for directly connection to PC, while a direct cable is used for connection to a hub.
• Connecting Audio
Connect speaker to audio output line and external mic to audio input line.
• Connecting Alarms
– A1, A2, A3, A4 (Alarm Input 1, 2, 3, 4)
You can use external devices to signal the camera to react on events. Mechanical or electrical
switches can be wired to the A1, A2, A3, A4 (Alarm Input 1, 2, 3, 4) and G (Ground)
connectors.
– G (Ground)
NOTE: All the connectors marked G or GND are common.
Connect the ground side of the alarm input and/or alarm output to the G (Ground) connector.
– AO (Alarm Output)
The camera can activate external devices such as buzzers or lights. Connect the device to
the AO (Alarm Output) and G (Ground) connectors.
• Connecting the Power
Connect power of 12VDC or 24VAC for the camera.
When using a 12VDC adapter, connect the positive (+) pole to the ‘+’ position and
the negative (-) pole to the ‘-’ position.
Use satisfy clause 2.5 of IEC60950-1/UL60950-1 or Certified/Listed Class 2 power source only.
– Be careful not to reverse the polarity when you connect the power cable.
– You can also use a router featuring PoE (Power over Ethernet) to supply power to the
camera.
– 24VAC is recommended to use for the camera power for stable operation with heater kit.
If using 12VDC or PoE, the heater will not operate at all.
