General Cautions and Notes for All Cable Installations
Maximum Cabling Distances

Caution
•
Faulty cable or wiring can cause all domes to fail or malfunction.
•
If several domes are powered from a single power source (multiple tap)
and noise is experienced on the UTP video output or coax video, then
an isolated power supply should be used to correct the problem.
•
Never run the cables close to potential sources of electromagnetic
interference such as motors, dimmers, and high-speed data trunk
cables.
•
For CE compliance, the power supply must be connected to a
CE-approved 240V UPS (uninterruptible power supply). See below for a
list of the power supplies which must be used to meet FCC and UL
requirements.
Note
For all cables:
•
The quality and specification of any cable used has a direct effect on the
quality of the video signal at the control equipment end of the system.
Compromising the cable quality and specification can lead to poor
video quality and system performance.
•
When other cables cannot be avoided, run cables perpendicular to
each other, not alongside, and keep this distance as short as possible.
Note
The terms shielded and unshielded are interchangable with screened and
unscreened, respectively.
