Caution:
To prevent fire or shock hazard, the UL listed
wire VW-1, style 1007 should be used for the
cable for AC 24V Input Terminal.
Video Cable
1. It is recommended to use a video monitor whose
resolution is at least equal to the camera's.
2. Terminate the camera output with 75-ohm resistor
at the furthest end of its cable run.
• It is recommended to use 75-ohm coaxial cable.
• Always set the last monitor's termination switch to
75 ohms, and set the termination switches of inter¬
mediate monitors to high impedance (Hi-Z) posi¬
tion.

Wiring precautions:
• Do not bend coaxial cable into a curve whose
radius is smaller than 10 times the cables diame¬
ter.
• Never staple the cable-not even with circular sta¬
ples. Mismatching will occur.
• Never crush or pinch the cable.
All of these will change the impedance of the
cable and cause poor picture quality.
♦ The maximum extensible coaxial cable length
between the camera and the monitor is shown in
the table 1. Since cable quality varies among man¬
ufactures, verify video quality before final installa¬
tion if maximum lengths are to be used.
