Outdoor RJ45 Ethernet Surge Protector SPD Lightning Arrester, Gigabit LAN Surge Suppressor Compatible with PoE PoE+ PoE++ Switch IP Camera, Inline Network Overvoltage Protection Device

This RJ45 network surge protector is a dedicated SPD (Surge Protective Device) lightning arrester designed for outdoor and surveillance network wiring. It effectively absorbs lightning-induced surges, static electricity and industrial voltage spikes to safeguard expensive PoE IP cameras, network switches, NVR recorders and wireless access points from burnout during thunderstorms.

It fully supports PoE, PoE+ and PoE++ power supply, transmitting data and power simultaneously without network lag or bandwidth loss, compatible with Cat5/Cat5e/Cat6/Cat7 ethernet cables. The sturdy metal shell delivers stable outdoor durability, suitable for monitoring poles, construction sites, garden and open-air wiring environments.

Equipped with an easy-to-wire grounding cable, simply connect the ground wire to a reliable earth terminal to maximize protection efficiency. Compact inline structure fits seamlessly between network cable and terminal equipment, no complicated tools or software required. Widely used for security monitoring systems, industrial control networks, outdoor smart devices and commercial PoE network projects.
