Description 1: RJ45 Connector Description 2: POE Splitter for IP Camera Description 3: POE Injector for IP Security Camera Description 4: POE Connector for IP Camera Application 1: Power Adapter Feature 1: Mini POE Splitter Feature 2: Mini Injector For optimal wireless LAN performance, careful placement of access points is crucial. Powering these access points often presents a challenge. Power over Ethernet (PoE) technology offers the ideal power solution to overcome these obstacles. In Ethernet, four pairs of C5 or C5E twisted pair cables are used as the transmission medium. However, actual data transmission utilizes only 4 pairs of wires (pairs 1 to 8). PoE technology leverages the remaining pairs (pairs 4-5 and 7-8) to conduct electricity. Data Pins: 1/2, 3/6 Power Pins: 4/5 and 7/8 Data Input: Connects to a computer, hub, or switch Ethernet Data Rate: 10/100 Ethernet Cable: / EIA 568 .5 Ethernet Cable Connector: RJ-45 Operating Temperature: 0 to 40 degrees Celsius Storage Temperature: -40 to 70 degrees Celsius Operating Humidity: 10% to 80% Storage Humidity: 5% to 90% Please note: This is for 10M/100M, adapter and network cable not included.
