Installation and connection
The maximum connection distance varies with
the type of cable used. Please refer carefully to
the table for each cable during connection.
* Be sure to turn off the power of devices before
connecting cables.
Video signal cables
Connect the coaxial cables (BNC) to the video
signal output connector (BNC).
DC 12 V or AC 24 V power supply cable
Connect the DC 12 V or the AC 24 V power
supply to the DC 12 V/AC 24 V terminals on the
terminal board. To prevent connection errors or a
cable disconnection, we recommend the use of
lug plates for the connections. The following table
shows the connection distances and connection
cables provided that 2-conductor VVF cables
(vinyl-insulated vinyl sheath cables) are used.
CAUTION:
●
If thin cables are used (i.e. with a high
resistance), a significant voltage drop will occur
when the unit is at its maximum power
consumption.
Either use a thick cable to restrict the voltage
drop at the camera side to below 10 %, or place
the power supply near to the camera.
When the voltage is low, the protection circuit
within the camera may be triggered and the
power of the camera may turn off automatically.
●
Do not allow input from both a DC 12 V and AC
24 V power supply at the same time.
●
When using a DC 12 V power supply, ensure
that the polarities of the cable are correct.
●
The product shall be powered by Class 2 only.
