kelvinset 0 Posted July 5, 2011 dear everyone: I found some interesting electronics component TMOV (Thermally protected MOVs). they introduce it to me . they said this component could protect the damaged from lighting for CCTV. and it is cheaper than the surge protective device. anyone has any ideas? anyone know that? also i know the CCTV do use fuse. could anyone told me which kind of fuse they use? is it radial fuse, axial fuse, or alloy fuse? and where is the fuse? anyone has any simple CCTV Circuit diagram. so i could learn from that. thanks. look forwards to hear from your guys help.

cglaeser 0 Posted July 5, 2011 they said this component could protect the damaged from lighting for CCTV. What are you trying to protect? The camera mounted outside, or people and equipment inside? If a camera takes a direct hit from a lightning strike, it's toast. If you want to protect the camera, you have to do what you can to ensure lightning does not strike the camera using a lightning rod or some other diversion (it will be safe inside a car). If lightning strikes the grid, then yes, there are precautions that will save the equipment further down the grid. Best, Christopher Share this post Link to post Share on other sites
