Overview of the Axis T8640
The Axis T8640 adaptor kit allows the installer to keep existing coax cabling when converting analogue systems into digital IP systems. It provides a cost-effective solution of delivering PoE as no new cabling is required.
The kit consists of the AXIS T8641 PoE+ over coax base unit and the Axis T8642 PoE+ over coax device unit. The base unit receives PoE power and transmits it down the coax cable into the device unit, which then delivers up to full PoE+ power to the network camera.
The kit features a helpful LED display, which gives confirmation of network and power status via the cable, with no need to access remote equipment to check connections.
An additional power supply (please select from dropdown) can be used alongside the device unit if the cable run is too long or the IP camera requires a higher level of power.
Cable runs lengths for PoE power levels are determined by the cable used and also the use of either a PoE switch or additional power supply. For more information see the table below.

Custom High PoE cameras
that use AXIS T8124 High PoE 60 W Midspan 1-port |
PoE to the camera is not supported. The Axis T8642 Device can be powered over the coaxial cable, but an Axis High PoE midspan 60 W must be used to power the camera locally. |
Key features
- Allows analogue camera systems to be upgraded to digital systems without having to replace cabling
- Supports both standard and high Power-over-Ethernet
- Plug-and-play for easy installation and configuration
