5026-401: T8640 PoE+ over Coax Adapter Kit, BNC & RJ45

Axis' PoE+ over Coax Adapter Kit that gives cost-efficient migration to network video for smaller installations

Product Rating
Product Overview
If you want to move to IP and it is time to replace your analogue video cameras, the AXIS T8640 PoE+ over Coax Adapter Kit is an efficient way to make the switch - and keep your Coax cabling. The AXIS T8640 PoE+ over Coax Adapter Kit includes two adapters, one for connecting a network camera to a Coax cable and one for connecting it to the network.

The T8640 PoE+ over Coax Adapter Kit from Axis Communications enables camera installers to keep previously installed coax cabling when converting an analog system into digital. It delivers standard PoE and centrally sourced power with no new cables required.

The T8640 kit is comprised of the T8641 Ethernet over Coax Base Unit PoE+ and the 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.

The PoE over Coax Adapter Kit is suitable for installation of network cameras where coax cables are already present and may be very long or inaccessible. For ease of installation, the adapter features an intuitive LED display, which gives confirmation of network and power status via the cable, so that you do not need to access remote equipment to check connections.

The T8640 adapter can be used in installations that require Power over Ethernet (PoE) transmission over 328' (100m). A full-rate network connection is delivered over maximum cable ranges that exceed recommended distances for analog video installation, so conversion of all existing coaxial cable types is predictable and reliable.

  • Reuse Coax cables and benefit from Power over Ethernet (PoE)
  • Suitable for long-range coax installations
  • Low upfront investment
