If you want to move to IP and it is time to replace your analog video cameras, AXIS T8640 PoE+ over Coax Adapter Kit is an efficient way to make the switch – and keep your Coax cabling. 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 (see Typical set-up).

Let your Coax cables do double-duty

AXIS T8640 PoE+ over Coax Adapter Kit lets you reuse hard-to-replace or long-range Coax cabling when you replace your analog cameras with Axis network cameras. And you can integrate Power over Ethernet over Coax for efficient power management. Range distances depend on the power required and the type of cable quality. With AXIS T8640 you can add local power to the device unit enabling higher power cameras to be used.

The right choice for smaller installations

With AXIS T8640 PoE+ over Coax Adapter Kit, you can replace your analog cameras with network video cameras at your own pace – one camera or several at a time. Because it is a single-channel solution, there is no need to invest in chassis or to replace more than one camera at a time. Simply add adapter kits as you need them.

Range table

The tables below shows the maximum distance from the network camera depending on cable quality and power source. When selecting your PoE+ over Coax device, both the range and camera installation needs to be taken into account.

For installations where a backbox or housing is available, AXIS T8645 or AXIS T8648 is recommended providing a compact and discreet installation.

For installations where long distances will be a limiting factor AXIS T8640 or AXIS T8646 is recommended since local power can be added to the device unit.

*The coaxial cable will power AXIS T8642 Device or AXIS T8643 Compact, but an AXIS 60W midspan is needed to power the camera locally.

Table 2:
Maximum range for PoE+ over Coax multi-channel kits (AXIS T8646 or AXIS T8648) being powered by either AXIS T8082 PS57 or AXIS T8085 PS57 power supply.
The same ranges apply to any single channel kit when powered with the AXIS T8003 PS57 power supply.
Power Source: Multi Channel with AXIS T8082 PS57 or AXIS T8085 PS57 power supply & Single Channel with AXIS T8003 PS57 power supply
