Description
IP54/NEMA 2
Protected against splashing water and the ingress of most dust.
IP65/NEMA 4
Completely protected against the ingress of dust and against low
pressure water jets from all directions, (limited ingress permitted),
and to be undamaged by the formation of ice on the enclosure.
IP66/NEMA 4X
Completely protected against the ingress of dust and against high
pressure jets from all directions, (limited ingress permitted), to be
undamaged by the formation of ice on the enclosure with the added
benefit of being corrosion proof.
IP67/NEMA 6
Temporary immersion in water (15-100 cm/6-39 inches) and
completely protected against the ingress of dust, and to be
undamaged by the formation of ice on the enclosure.
Cabling 4.2
Cabling should be routed for the shortest path and minimizing impedance. Cabling routes should be
planned for the fewest bends. Avoid unnecessary connections and use only approved connectors in
locations that provide accessibility.
This section discusses different considerations for the different cabling types:
 Video Cable
 Electrical/Power Supply Cables
 Electrical Power Input
4.2.1 Video Cable
Use the appropriate connectors for indoor outdoor cabling. Cables should be maintained at
scheduled intervals, connections should be secured. Worn or damaged cables should be replaced to
ensure optimally low impedance.
Recommended Cable Specifications:
 75Ω coaxial cable impedance
Note:
Using a cable longer than the manufacturer’s specifications for optimal video signal
may result in degradation of color and video parameters.
Caution:
To avoid damage to the system and system interference, a certified electrician must
ensure that the ground voltage (ground loops and foreign stray voltage) is comparable
among all connected system components. Shielding of video cables and equipment racks,
as well as a ground isolation transformer, may be required to solve ground loop problems.
This relates to all grounded devices.
