Axis 5026-401 Product Data Sheet
AXIS T8640 Ethernet over Coax Adaptor PoE+
Upgrade to IP but keep the coax.
DATASHEET
> No need for re-cabling,
keep the coax
> Carries PoE and PoE+
over the coax cable
> Ease of installation
> Reliable conguration
AXIS T8640 enables camera installers to keep the legacy coax cabling when converting an analog
system to digital. It delivers standard PoE and centrally-sourced power with no new cables required.
AXIS T8640 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, AXIS T8640 features an intuitive LED display, which gives conrmation of network
and power status via the cable, with no need to access
remote equipment to check connections.
AXIS T8640 can be used in those installations that
require Power over Ethernet transmission over 100 m
(328 ft.). A full-rate network connection is delivered
over maximum cable ranges that far exceed most recommended distances for analog video installation, so
conversion of all legacy coaxial cable types is predictable and reliable.
AXIS T8640 comprises AXIS T8641 Ethernet over Coax
Base Unit PoE+ and AXIS 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.

Low power PoE cameras
Network cameras that are PoE IEEE 802.3af Class
1 or 2 (<6 watts), for example:
AXIS M11 Network Camera Series
AXIS 221 Network Camera
AXIS M30, AXIS M31-R, AXIS M31-VE,
AXIS M32 Network Camera Series
AXIS P33 Network Cameras (Indoor models)
AXIS 212PTZ/-V Network Camera
Medium power PoE cameras
Network cameras that are PoE IEEE 802.3af Class
1, 2 or 3 (<10 watts), for example:
AXIS M1054 Network Camera
AXIS P13 Network Cameras (Indoor models)
AXIS Q16 Network Cameras (Indoor models)
AXIS Q1755 Network Camera
AXIS Q19 Network Camera Series
AXIS P33-VE Network Cameras
Full power PoE or PoE+ cameras
Network cameras that are PoE IEEE 802.3af Class
3 (>10 watts) or IEEE 802.3at, for example:
AXIS P13-E Network Cameras
AXIS Q16-E Network Cameras
AXIS Q1755-E Network Camera
AXIS P55 Network Camera Series
AXIS Q60 Network Cameras (Indoor models)
Custom High PoE cameras
Network cameras that use AXIS T8124 High PoE
60 W Midspan 1-port, for example:
AXIS Q60-E Network Cameras
150m (492 ft.) of CCS RG-59
350m (1148 ft.) of CC RG-59
400m (1312 ft.) of CC RG-6
500m (1640 ft.) of CC RG-11
CCS RG-59 not supported
350m (1148 ft.) of CC RG-59
400m (1312 ft.) of CC RG-6
500m (1640 ft.) of CC RG-11
Not supported 80m (262 ft.) of CCS RG-59
PoE to the camera is not supported. The AXIS T8642 Device can
be powered over the coaxial cable, but an A XIS T8124 60 W
midspan must be used to power the camera locally.

CC = Copper-Cored Cable (most common for correctly
installed analog video)
CCS = 22AWG Copper-Coated Steel (shows worst-case
performance if cable type is not known)
Note: The actual range depends on several factors such as cable quality, cable thickness, connectors and camera
power consumption.
Range figures assume short (<5 m or 16 ft.) Cat-5e cables between equipment.
