Dahua ePoE IP system delivers up to 800 metres transmission between ePoE camera and ePoE network switch or ePoE NVR at 10Mbps & 13W or 300m @ 100Mbps & 25.5W. It overcomes the limitation of traditional Ethernet and PoE (both restrict cable distances to 100 metres between network ports) and eliminates the need for Ethernet extension devices or additional network switches. Moreover, according to test results, an ePoE IP system will not increase transmission delay or package loss rate compared to a traditional IP system.

For surveillance of large spaces such as big warehouses, parks and outdoor parking, cameras are usually over 100 metres away from the control centre. Conventional approaches, such as adding repeater devices and fibre optics, increase equipment and installation costs and also often form too complicated a system. Dahua's ePoE IP system, with 300-metre transmission at 100Mbit/s via network cable and only one cable required to connect front-ends and back-ends, offers a simple, cost-effective and reliable solution.

A proper solution to migrate analogue surveillance system to IP needs to adapt the IP video signal and RJ45 connection to coaxial cable, support the length of coaxial cable and transmit power over coaxial cable. Dahua ePoE IP system, uses PoC Extender LR1002 to connect the IP camera Ethernet port or network switch on the one end and a BNC connector of coaxial cable on the other, supports up to 1,000-metre transmission over coaxial cable at 10Mbit/s, and delivers PoE power to IP cameras. This is a simple and effective solution that significantly reduces the cost of analogue to IP migration.

The enriched Dahua ePoE IP system, which will be on display at Ifsec International later this month in London, offers a better way to accomplish long-distance transmission between IP cameras and network switches or recorders and allows more flexible system design, improves reliability and saves construction and wiring costs.
