Power connection
1. Use a class 2 power supply 24 VAC or +12 VDC.
2. Connect the power wires (red+ , brown-) to the power
supply.
3. Connect the earth wire (yellow/green) from the camera to
the system earth of the installation to ensure correct EMC/
RFI and safety protection.
Network (and PoE) connection
1. Use a shielded twisted pair (STP) Category 5e cable,
maximum length 100 meters.
2. Use the RJ45 female-to-female network cable connector to
connect the network cable of the system to the RJ45
connector of the camera (Auto MDIX compliant -
automatically detects the cable connection type).
Power is supplied to the camera via the Ethernet cable,
compliant with the Power-over-Ethernet standard.
Note:
The RJ45 female-to-female network cable connector supplied is
unshielded.
To comply with the EMC Alarm immunity standard (EN50130-4)
or the EMC Railway immunity standard (EN50121-4), a shielded
twisted pair (STP) connection cable and a shielded RJ45
female-to-female network cable connector (not supplied)
should be used.
Alarm Input
Use the alarm input to connect external alarm devices such as
door contacts or sensors. A zero potential make or break
contact can be used as the actuator (use a bounce-free contact
system).
– Refer to the cable tree table to identify the wire colors for
connecting the alarm input.
– Configurable as active low or active high.
