AXIS T8129 2 Port Plug & Play PoE Extender, 10/100 Mbps, IEEE 802.3af/t, Up to 200m

AXIS T8129 PoE Extender — Use Cases

The AXIS T8129 PoE Extender is used when a PoE camera needs to be installed beyond the normal 100m Ethernet limit. It is installed inline on the Cat5e/Cat6 cable and does not require a separate power supply, as it passes power and data through from the PoE switch or midspan. Axis states that depending on the camera and power source, total cable distance can reach 200–400m.

Common use cases

1. Long camera runs over 100m
Ideal when a camera is slightly too far from the switch/NVR location, such as a warehouse, car park, driveway, factory, school, farm shed, or gate entry.

2. Avoiding an extra switch in the field
Instead of installing a powered network switch halfway along the run, the T8129 can extend the PoE cable inline without needing a local power point.

3. Retrofitting existing cable paths
Useful when the cable has already been run but exceeds normal Ethernet distance. The extender can be added at around the 100m point to continue the run.

4. Axis PTZ or higher-power camera installations
For higher-power PoE/PoE+ devices, range is more limited. Axis gives the example of a 25W PTZ dome camera reaching up to 200m using a single T8129, depending on the power source and cable conditions.

5. Low-power fixed camera runs up to 400m
For low-power cameras, Axis states that a regular 5W network camera may reach up to 400m by using three T8129 extenders at 100m intervals.

6. Clean indoor comms/security installations
The T8129 is listed for indoor use, so it suits comms rooms, risers, ceiling spaces, indoor warehouses, office buildings, corridors, plant rooms, and protected indoor cable routes.

When not to use it

Do not treat this as a universal fix for every long cable run.

For very long outdoor runs, lightning-prone areas, inter-building links, or electrically noisy industrial sites, fibre is often the better solution. The T8129 is also not ideal if the camera’s power draw is too high for the available PoE budget, or if the extender would need to be installed outdoors without a suitable enclosure.

FAQs

What does the AXIS T8129 PoE Extender do?

It extends a PoE network connection beyond the standard 100m Ethernet limit, carrying both network data and PoE power further along the cable.

Does the AXIS T8129 need its own power supply?

No. Axis states that the T8129 does not require an additional power supply. It is powered from the PoE switch or PoE midspan and passes power through to the connected device.

How far can it extend a PoE camera?

It depends on the camera’s power draw, the PoE source, and the cable used. Axis states total distance can be between 200m and 400m depending on the setup.

Can I use more than one extender?

Yes, for low-power devices. Axis gives the example of using three T8129 extenders at 100m intervals to reach up to 400m for a regular 5W network camera.

Will it work with PTZ cameras?

Yes, but distance depends heavily on the PTZ camera’s power requirement. Axis gives an example of a 25W PTZ dome camera being installed up to 200m away using a single T8129.

Is it compatible with PoE and PoE+?

Yes. Axis lists the T8129 as compatible with IEEE 802.3af, IEEE 802.3at and High PoE 60W power sources.

Is it only for Axis cameras?

Axis states it is compatible with all Axis network video products with PoE. For non-Axis PoE cameras, compatibility may depend on power class, cable quality, and PoE standard, so it should be checked case by case.

Can it be used outdoors?

The product is listed by Axis for indoor use. For outdoor use, it would need appropriate environmental protection, but for exposed outdoor installations a purpose-built outdoor extender or fibre solution may be more suitable.

What cable should be used?

Axis specifies range figures based on 24AWG or heavier Cat5e/Cat6 cable, and notes that some higher-power 200m applications require 23AWG or heavier cable, typically Cat6.

Does it reduce network speed?

Axis states that the T8129 maintains full-rate network throughput, with the Ethernet ports automatically configured for link speed, duplex, and crossover.
