Surge Protectors

Network and AC surge protection for outdoor cameras, access control panels, intercoms, and infrastructure exposed to lightning, power transients, and inductive switching. Surge protective devices (SPDs) prevent damage to ports, power supplies, and integrated electronics — the failure mode that quietly takes systems offline after every storm season.

Where Surge Protection Belongs in a Security System

  • Outdoor PoE devices: at the camera, intercom, or AP end of the run — inline Ethernet surge protectors clamp transients before they reach the device PHY.
  • Building entrance: service entrance SPDs protect the panel and downstream gear from utility transients and nearby strikes.
  • Long copper runs: RS-485 access readers, coax video, and twisted-pair video benefit from inline signal-line SPDs.
  • Cabinet level: rack-mount AC SPDs and Type 3 plug-in SPDs protect recorders, controllers, and managed switches.

Match the SPD type to the location and energy class: Type 1 at the service entrance, Type 2 at distribution panels, Type 3 at the equipment outlet. For outdoor camera installations, look for SPDs with low clamping voltage and pass-through PoE budget that matches the camera's 802.3af/at/bt class.
