International Orders*The Axis Communications T8640 Ethernet over Coax Adapter PoE+ enables camera installers to keep legacy coax cabling when converting an analog system into digital. It delivers standard PoE and centrally sourced power with no new cables required.
The Ethernet over Coax Adapter is an ideal choice for installation of network cameras where coax cables are already present and may be very long or inaccessible. For ease of installation and guaranteed performance, the adapter features an intuitive LED display, which gives confirmation of network and power status via the cable, with no need to access remote equipment to check connections.
The T8640 adapter can be used in those installations that require Power over Ethernet (PoE) transmission over 328' (100 m). A full-rate network connection is delivered over maximum cable ranges that exceed recommended distances for analog video installation, so conversion of all legacy coaxial cable types is predictable and reliable.
The T8640 adapter comprises a T8641 Ethernet over Coax Base Unit PoE+ and T8642 Ethernet over Coax Device Unit PoE+. The base unit receives PoE power and transmits it down the coax. The device unit receives power from the coax and delivers up to full PoE+ power to the network camera. An optional power supply can be used if PoE is not available or if higher power for the network camera is needed.
