To protect camera systems from lightning and surge voltages, the type of camera must first be identified. The protection requirements differ depending on whether it is an IP camera or an analog camera.

Analog Camera Protection
1- Power Supply Protection | Class C SPD
2- Video Signal Protection | Class D SPD BNC Protection 12 V
3- Control Cable Protection | Class D SPD Data Line Protection

As you can see, protecting cameras against lightning and surges requires a **coordinated multi-stage protection**. Sensitive devices can be protected using products selected according to the appropriate Up protection level. Accordingly, in main panels use B+C class, in secondary panels use Class C, and finally, in front of the device, a Class D SPD should be installed according to the system specifications.
