The most recognized cause of transient voltage is lightning; however, the most frequent source is the local power grid.
Axis network cameras for outdoor installation are protected by design against power surges and transients. Part of this design involves using a shielded network cable STP between the PSE (Power Sourcing Equipment)* and the camera to ensure a path for the power surge to reach ground.
The installation of Axis cameras using a shielded cable STP and a properly grounded PSE has been tested to comply with industry immunity standards levels, for example for surge protection. Any other installation method will void the warranty and leave the unit at risk.
Always use a shielded network cable STP between the camera and the PSE, and ensure that the PSE is properly grounded.

* The term PSE defines any device connected at the camera end of the cable, such as a midspan, endspan, network switch, network hub or power injector.
