CCTV cameras are very sensitive to electrical problems.
First of all, Voltage surges are very dangerous for
CCTV systems. Electrical machine tools, short-circuit, or nearby lightning
strikes may create high voltage surges that can seriously damage
cameras and other video equipment in a matter of instants.
When occasional surges occur in a CCTV system, the video signals from one or
more cameras suddenly disappear. This
happen out of the blue, without any previous sign of irregular service. Very
often the users tent to believe that the high quantity of faults is due to
low quality CCTV products.
Ground loops are another potential
trouble source, mainly in large CCTV systems.
Low currents, due to different ground potential, may flow along the shield of the coaxial cable, creating unwanted video effects.
(See tutorial)
DSE video protection devices are specifically designed for protecting the
video input of CCTV equipment. They can be used on coaxial cable or twisted
pairs, if video balun are used.
RE-PR1/2/3 Surge suppressors
RE-BNCG1 Ground loop insulator
RE-PR1 video protection for coaxial
cables
Surge suppressor for BNC
video input
RE-PR1 protection module must be connected to the end of coaxial
cables, right before the device to be protected (camera, monitor, DVR etc.).
The product has one female BNC connector on one side (cable IN) and one male
BNC connector on the other side in order to be fitted straight to the camera
(device) video input. Besides, the module has a ground cable that need to be
connected to the ground for ensuring the effective protection of the device.
In case of voltage surge, the RE-PR1 module is able to react in less than
100 ns. protecting the camera from current up to 5000A.
The module can bear up to 300 surges of 100A each before being replaced.
Protection device does not need to be powered.
Overall size: 25x25x78 mm. Weight: 80 gr.
RE-PR2 video protection for twisted
pair
Surge suppressor for RJ45
video input
RE-PR2 protection module, is similar to the previous model, but
has been developed to protect video inputs over twisted pair cables when
video baluns are used. RE-PR2 can
be used with both passive (RE-BNCRJ1) and active (RE-BNCRJ2) baluns.
RE-PR2 module must be connected to the end of the twisted pair cable, right
before the video balun which is then connected to the camera. For this
reason the product come with 2 RJ45 jacks (IN/OUT). Besides, the module has
a ground cable that need to be connected to the ground for ensuring the
effective protection of the device.
Protection device does not need to be powered.
Overall size: 25x25x85 mm.
Weight: 90 gr.
RE-PR3 video protection for coaxial
cable + data
Surge suppressor for BNC
video input and RS485 serial bus, to be used with speed-dome cameras
RE-PR3 protection module, is similar to the RE-PR1 type, but
besides the video protection, has been designed to protect one RS485 data
input, widely used for speed-dome cameras control.
The protection module must be installed between the video/RS485 cables and
the speed dome camera. It protects both the video circuit and the Pan/Tilt
control of the speed-dome camera.
RE-PR3 module comes with 2 female BNC connectors (IN/OUT) and 2 DATA IN + 2
DATA OUT terminals. Besides, the module has a ground terminal that needs to
be connected to the ground for ensuring the effective protection of the
device.
Protection device does not need to be powered.
Overall size: 67x27x87 mm. Weight : 136 gr.
RE-BNCG1 ground loop protection for coaxial
cable
BNC video input insulator
RE-BNCG1 protection module, must be connected straight to the camera's video output and cut down the effect of ground loops.
The module also includes a surge suppressor against voltage spikes. RE-BNCG1 does not require any power and can be easily installed
both on new CCTV systems or existing systems where ground loop problems already exist.
BNC male (camera side) + BNC female (cable side)
Size: 28x21x84 mm. Weight: 80 gr.
