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 for the camera.
When using a 12VDC adapter, connect the positive (+) p
ole 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.
– If you use PoE to supply power to the camera, this must be from a PoE+ switch or use the
PoE injector provided with the camera. Note that this is an injector, not a midspan
– so
standard network distances apply (90m).
