Lightning Protection for Surveillance Cameras

By IPVM Team, Published Oct 12, 2022, 10:35am EDT (Info+)

Lightning strikes can cause significant damage and major expenses for surveillance systems, so how can integrators and end-users protect systems against this powerful, unpredictable and destructive force?

An unprotected hit by lightning will destroy a camera and put other connected devices, such as switches, recorders, and servers at risk. In this report, IPVM examines lightning protectors, their cost, usability, when they are needed, types to consider, and how to install them.
