Universal PoE standard compliance: Works with IEEE 802.3af/at standard equipment to deliver 10/100 Mbps Ethernet. It powers standard PoE devices such as IP cameras, phones, and speakers. Not compatible with 24V PoE devices. Onsite IP camera configuration: Insert the extender into your existing network to adjust IP camera angles and settings from a laptop or CCTV tester. This device is designed specifically for standard PoE equipment. Extended range and cascade capability: Adds an extra 100 meters for both PoE power and data. Supports a twolevel cascade setup, allowing up to 200 meters of transmission range with a 30W input and dual 15W outputs. Dualport PoE power: Power two PoE devices over a single Cat5E/6 cable without an additional power adapter. Compatible with PoE switches and NVRs from 44V to 55V, simplifying the addition of devices to your network. Use scenarios Remote surveillance installations: Extend PoE and data to IP cameras located far from the main switch or NVR, while enabling onsite camera configuration via a laptop or CCTV tester. Longrun campus or facility deployments: Deploy along corridors or between buildings with cascade extension to achieve up to 200 meters of total transmission range for multiple PoE devices. Small office or retail setups: Power two PoE devices such as a camera and a VoIP phone over a single Cat5E/6 cable, without needing extra power adapters.
