VIDEO SURVEILLANCE > Video protections

CCTV cameras are very sensitive to electrical noises.

Voltage surges are very dangerous for CCTV systems.
Electrical machine tools, short-circuits, or nearby lightning strikes may create high voltage surges that can seriously damage cameras and other video equipments in a matter of instants.
When occasional surges occur in a CCTV system, the video signals from one or more cameras suddenly disappears. This happens out of the blue, without any previous sign of abnormal service.

Ground loops are another potential trouble source, mainly in large CCTV systems. Low currents, due to different ground potentials, may flow along the shield of the coaxial cable, creating unwanted video effects.

VSE video protection devices are specifically designed for protecting video inputs of CCTV equipments. They can be used on coaxial cable or twisted pairs, if video balun are used.

SUR-VRE-SPR1E


Protection for BNC video input (Video surge protections)
BNC video protection for cameras connected to coaxial cables.

 

Features

  • BNC
  • No power required
  • 5000A protection
  • 100 ns attack time
  • Long durability

Applications

NPR1S 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 needs to be connected to the ground for ensuring the effective protection of the device.
In case of voltage surge, the NPR1S module is able to react in less than 100 ns protecting the camera from currents up to 5000A.
NPR1S 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 g.
Don't forget to order the adapters NBNCRCA1S and NBNCRCAS2 should the video cable, or the device, have RCA connectors.

SUR-VRE-SPR2E


Protection for RJ45 video input (Video surge protections)
RJ45 video protection for cameras connected to twisted pairs.

 

Features

  • CAT5
  • No power required
  • 5000A protection
  • 100 ns attack time
  • Long durability

Applications

NPR2S protection module, is similar to NPR1S, but has been developed to protect video inputs over twisted pair cables when video baluns are used. NPR2S can be used with both passive (NBNCRJ1S) and active ((NBNCRJ2S) baluns.
NPR2S 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 g.
Don't forget to order the adapters NBNCRJ1S and NBNCRJ2S for video transmission on twisted pair cable.

SUR-VRE-SPR3E


Protection for BNC video input and RS485 serial bus (Video surge protections)
BNC video protection and RS485 data bus for speed dome cameras connected to coaxial cables and twisted pair.

 

Features

  • BNC, DATA
  • No power required
  • 5000A protection
  • 100 ns attack time
  • Long durability

Applications

NPR3S protection module is similar to NPR1S, but besides the video protection, it 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.
NPR3S 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 g.
Don't forget to order 2 adapters NBNCRCA1S should the input video cable or the output cable to the device, have RCA connectors.

SUR-VRE-SBNCG1E


Protection for BNC video input against ground loop (Video surge protections)
BNC ground loop insulator for cameras connected to coaxial cables.

 

Features

  • BNC
  • No power required
  • No ground required

Applications

NBNCG1S protection module, must be connected straight to the camera's video output to cut down the effect of ground loops. The module also includes a surge suppressor against voltage spikes. NBNCG1S 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).

 
Overall size: 28x21x84 mm. Weight: 80 g.
Don't forget to order 2 adapters NBNCRCA1S should the input video cable or the output cable to the device, have RCA connectors.
