Outer Application
Diameter
10.3 mm Used for long drops and underground, also available in
versions for plenum use
6.2 mm Main internal cable runs. May also be used externally in
containments or when damage is unlikely. Not very flexible.
2.54 mm Used for shorter drops, higher attenuation but is flexible
6.2 mm Main internal cable runs. May also be used externally in
containments or when damage is unlikely. Not very flexible.
5.8 mm Patch cables from main runs to equipment. Equipment
interconnection. Flexible and useful for tight bends.
7.8 mm Duct/containment rated cable for external main cable runs.
Some grades are suited for direct burial.
CAT5 cabling for video transmission allows multiple domes to be transmitted down the
same multicore CAT5 cable without dome video interference or crosstalk. Requires one
wire pair per dome. It can support up to four domes on a single CAT5 cable.
Adhere as closely as possible to the following recommendations when installing with
CAT5 cable and UTP receiving equipment.
• A UTP receiver module must be used at the control end of the system for every
dome that is transmitting video via CAT5. A UTP hub can be used to receive up to
16 domes using CAT5 cable.
• PTZ telemetry is possible when a passive UTP receiver module or hub is used at the
control end of the system. If an active receiver is used at the control end of the
system, then RS485 telemetry must be used. This requires another single twisted
pair per dome.
• When wiring via twisted pair, always ensure that you are actually using a twisted pair
by examining the cable. Failure to use wires from the same pair leads to noise
introduction and subsequent video and telemetry problems.
• The twisted pair cable used must not be shielded/screened in any way, either by
foil, braided shield, or any other means. The use of any cable other than unshielded
twisted pair (CAT5 or better) may lead to a reduction in performance and is solely
the responsibility of the installer.
