Camera cable guidelines
When installing camera cable, follow these guidelines:
• Avoid excessive lengths of cable at the control and device end. Pull back
excess cable to a duct area where it can be folded and secured. Leave a
service loop as directed for specific devices.
• Cables should not come into contact with bare metal edges, light ballasts, or
magnetic speaker coils. If ballasts and speaker coils cannot be avoided, cross
them perpendicularly.
• Do not tighten cables that are secured with cable-ties to the extent that the
cable is compressed or damaged. Do not crimp, crush, or severely bend the
cables.
• When passing cables through tapping plates or metal sidewalls of the vehicle,
if possible, insert grommets in the holes to protect the cables. If it is not
possible, make sure that the protective outer CL2 jacket is maintained when
passing the cables through the holes.
• When pulling cable through the conduit, do not jerk or overpull the cables.
These actions will stretch and damage the cable. If you must pull cables
through vehicle walls with limited access or conduit, attach a pull line to the
cable jacket, not to the connector, and gently pull the cable through the
appropriate routing paths.
• Route cables from each camera location to the DVR location as determined
by your specific system layout. Figure 3 on page 10 shows an example of
cabling layout.
• After reaching camera locations, leave enough cable for a 12 to 18 in. (152
mm) service loop at each location.
