Video Cable
Use the appropriate connectors for indoor an outdoor cabling. Cables should be maintained at
scheduled intervals, connections should be secured, and worn or damaged cables should be
replaced to assure optimally low impedance.
Recommended Cable Specifications:
•
75
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.
Warning
To avoid damage to the system and system interference, a certified electrician must assure
that the ground voltage (ground loops and foreign stray voltage) is comparable among all
connected system components (ground isolation transformer may be required to solve
ground loop problems). This relates to all grounded devices as well as the shield of video
cables and equipment racks.
Electric/Power Supply Cables
The following should be considered for electrical wiring and cables:
Warning
To prevent bodily injury or possible death, shut off the electrical current at the main switch
before tying-in wiring.
Warning
:
The ioibox unit uses a three-wire power cord to make sure that the product is properly
grounded when in use. The plug on this cord will only fit into a grounding-type outlet. This is
a safety feature. If the intended power outlet does not support three prongs, one of which is a
ground, contact an electrician to install the appropriate outlet. NEVER remove or otherwise
attempt to defeat the ground pin of the power cord. Do not operate the ioibox unit in the
absence of a suitably installed ground conductor
