above table, a camera may malfunction if there is an excessively long cable run.
Resistance of copper wire [at 20C˚ (68˚F)]
* Voltage for camera operation: 12V DC ±10%
* Voltage drops in the above table are variable according to types of cable manufacturer.
Connecting to RS-485 Control Cable
• Be sure to connect power only after all the installation is complete.
• Note that AC or DC adaptor is not supplied with camera.
• Use the UL listed, class 2 power transformer of AC 24V adaptor.
• Ground should be connected to the GND terminal.
