Electrical spikes and overvoltages are very dangerous for both IP and analog CCTV cameras. High power equipment, lighting and short circuits can generate voltage spikes of various nature and duration which can destroy, in a fraction of a second, any camera. Depending on its power and duration, a spike can destroy the whole camera or just cause a small demage, leaving no evidence. In a CCTV system the presence of occasional overvoltages generates frequent damages to the cameras, causing sudden "no video" signal. Very often the large number of faults is wrongly attributed to a poor quality of the cameras.
All cameras installed outdoors, with underground or aerial cabling, are at risk of spikes.
These surge suppressor for CCTV cameras can protect your video surveillance system agains electrical spikes and overvoltages.
Overvoltage protection for analog cameras
This is an overvoltage protection for coaxial cable, perfect for analog cameras and DVRs, supporting CVBS, AHD, TVI and CVI video format.
It connects to the end of the coaxial cable , just before the device you wish to protect (camera, monitor, video recorder etc.). The product is equipped with a female BNC connector, for the coaxial cable, and a male BNC connector for the device. There is also a ground cable that must be connected to the earth and is essential to guarantee an effective protection.
This product protects your devices against any type of overvoltage, caused by lightning or faults.
In case of overvoltage, this surge suppressor is able to switch off in less than 100 ns. interrupting any currents up to 5000A. This lighting protection is able to withstand about 300 overcurrents of 100 A before needing replacement.
This device does not require power supply.
Dimensions: 25x25x78 mm. Weight: 80 gr.
Overvoltage protection for analog cameras on twisted-pair cable with balun
Just like the previous model, this is also an overvoltage protection device for analog cameras and DVRs, supporting CVBS, AHD, TVI and CVI video format. Unlike the previous model, it is used when the analog video signal runs through a twisted cable, by means of video baluns. This protection is suitable for both passive and active video baluns. It cannot be used to protect network devices, like IP cameras.
This surge suppressor connects between the incoming twisted cable and the device to be protected. It comes with 2 RJ45 sockets (IN-OUT) for the connection of the network cable that is normally used for this type of video wiring. There is also a ground cable that must be connected to the earth and is essential to guarantee an effective protection.

Dimensions: 25x25x85 mm. Weight: 90 gr.
RJ45 overvoltage protection for IP cameras and network devices
This is an overvoltge protection unit suitable for network devices. It is perfect for IP cameras, NVRs, switches and any kind of network peripheral. This protection module has to be placed between the incoming Ethernet cable and the device to be protected. It is equipped with 2 RJ45 sockets (IN-OUT). There is also a ground cable that must be connected to the earth and is essential to guarantee an effective protection.
This product protects the device against any type of overvoltage, caused by lightning or faults.

Overvoltage protection for motorized analog cameras
This is an overvoltage protection device for coaxial cable and RS485 serial line. It is perfect for analog motorized PTZ cameras, supporting CVBS, AHD, TVI and CVI video format.
This protection module is similar to the RE-PR1 module, but provides the additional protection of the RS485 serial line , which is used for sending PTZ commands to most motorized cameras.
This surge suppressor connects between the incoming video-RS485 cable and the camera/DVR to protect both the video circuit and the PTZ control.
There are 2 female BNC connectors (IN / OUT) and 2 DATA IN 2 DATA OUT terminals. There is also a ground cable that must be connected to the earth and is essential to guarantee an effective protection.
This product protects the device against any type of overvoltage, caused by lightning or faults.
In case of overvoltage, this surge suppressor is able to switch off in less than 100 ns. interrupting any currents up to 5000A. This lighting protection is able to withstand about 300 overcurrents of 100 A before needing replacement.

Dimensions: 67x27x87 mm. Weight: 136 gr.
The analog video signal, CVBS or high resolution AHD / CVI / TVI, can be polluted by interference due to electromagnetic fields along the cabling. The main causes of video noises are ground loops, due to the different potential of the ground points of the system, as well as AC currents flowing near the video cabling. The protection shield of the video cable is ineffective against this kind of low frequency interferences.
If your video surveillance system is effected by these problems, you can try these video noise suppression filters.
Ground loop isolator for analog cameras
Ground loops can cause serious problems to analog CCTV system, especially in medium / large systems. Small eddy-currents can flow through the cable shield, exploiting the different potential between the ground points of the system, generating unwanted video noises (See tutorial ).
If your monitor displays slightly distorted images or moving bands in the background , this ground isolator can help you because it interrupts the ground circuit, still allowing the video transmission. It connects along the video cable, preferably where the cable that comes from the camera connects to the rest of the system.
This isolator is suitable for analogue AHD, TVI, CVI cameras. In addition includes a surge suppressor against overvoltages.
The device requires no power supply.
Connectors: BNC male on camera side + BNC female / terminal block on wiring side.
Dimensions: 49x20x17 mm. Weight: 80 gr.
