The PARUHT Outdoor Waterproof PoE Repeater extends both power and data transmission to four PoE devices via an RJ45 network cable. Device auto-detects IEEE802.3af/at standards (15.4W/30W) for compatible devices, but only supports 44-57V PoE devices. Designed for durability, it features IP33 and 4KV lightning protection, making it suitable for outdoor use in temperatures ranging from -10°C to +55°C (14°F to 131°F). This makes it ideal for small security camera installations, as it enhances network signal transmission and extends the power supply distance. The PoE repeater extends data transmission by an additional 330ft (100m) and supports cascading up to three levels for a total distance of 1312ft using four PoE extenders. Ports 1-4 are equipped with VLAN isolation to reduce network traffic and improve security. The device is plug-and-play, automatically detecting connected devices and delivering power and network connectivity without the need for configuration. Suitable for various outdoor installations, it ensures reliable performance and extended coverage. Note: A power adapter is not included and must be purchased separately if needed.
