Video, Data and Power Surge Protector w/Built-In Balun

Installation and

Operation Manual

Description

The CAMTRV24 is a single channel video balun transceiver used for UTP video transmission combined with a
multi-function surge protector for in-line video, 2 wire P/T/Z control and the camera supply voltage. The CAMTRV24
is suited for outdoor cameras, where protection on all signal connections is required. The CAMTRV24 provides a
heavy-duty, single point ground connection. Proper installation is critical for proper operation of the unit. Please
read the instructions completely and insure good ground connections.

Installation

The CAMTRV24 must be properly installed to insure maximum
protection. The function of the CAMTRV24 is to allow a surge to be
routed to ground and to clamp the protected equipment inputs to a
minimum voltage.
There are three key points to remember when installing the
CAMTRV24. First, provide a low impedance connection between the
CAMTRV24 and your protected equipment. This is best done by keeping
the PROTECTED cable connections as short as possible.
Second, the system should use a single ground point. Connect
the grounding stud of the CAMTRV24 to a single ground point. A single
ground point is a proper building ground or earth ground to which
equipment grounds are connected. Ideally the protected equipment
should be isolated from ground. If the CAMTRV24 and the protected
equipment are both grounded you will provide a parallel path to ground
and a portion of the surge current can flow through that path.
Finally, the UNPROTECTED cables should not be crossed with
the PROTECTED cables. Crossing cables could provide a path for surge
currents to bypass the CAMTRV24 protection circuits.
