Product SKU: TU8003
Product Overview
When high-power PTZ cameras or advanced surveillance devices exceed the output capacity of standard network switches, the AXIS TU8003 90W PoE Midspan provides a direct solution. Designed as a single-port connectivity injector, it delivers up to 90W of power and Gigabit data over a single Ethernet cable in compliance with the IEEE 802.3bt Type 4 standard, making it suited to demanding Axis installations where existing switch infrastructure cannot be replaced. Featuring Axis Portcast technology, the TU8003 extends audio and I/O connectivity to the connected device using the camera’s own IP address, allowing audio and control signals to travel in the same network stream as video without additional VMS licensing. It also includes an integrated SFP slot for installations where fibre connectivity is required. This makes it a practical infrastructure component for integrators deploying high-power Axis cameras in commercial, industrial, or long-distance network environments.
Key Capabilities
90W IEEE 802.3bt Type 4 Power Delivery
The TU8003 meets the IEEE 802.3bt Type 4 standard and supplies up to 90W per port, providing sufficient power for high-demand devices such as Axis PTZ cameras that draw well beyond the 30W ceiling of standard 802.3at switches. It is also backward-compatible with 802.3af and 802.3at devices.
Axis Portcast Audio and I/O Integration
Portcast technology routes audio inputs and digital I/O signals through the same Ethernet connection used for camera data, presenting these interfaces under the camera’s IP address. This removes the need for separate cabling runs or additional VMS licences to access microphone and I/O functionality.
Integrated SFP Slot for Fibre Networks
The built-in SFP port allows the TU8003 to connect into fibre network infrastructure, supporting longer cable runs that exceed the 100-metre limit of standard Ethernet. This is particularly useful for cameras mounted at distance from the main network rack or IDF.
Gigabit Single-Cable Power and Data
By combining 10/100/1000 Mbps data throughput with up to 90W of electrical power over one Ethernet cable, the TU8003 simplifies installation at the camera end and avoids the need for a secondary power circuit at the mounting location.
Flexible Deployment Without Switch Replacement
Installed inline between an existing network switch and the camera, the TU8003 adds high-power PoE capability without requiring the switch itself to be upgraded. This reduces infrastructure cost when only one or a small number of high-power devices need to be added to an existing installation.
Best For
- High-Power PTZ Camera Deployments: Provides the 90W output required by advanced Axis PTZ cameras that draw beyond the capacity of standard 802.3at PoE switches.
- Audio-Integrated Surveillance Systems: Portcast technology allows microphones and I/O devices connected to the TU8003 to appear as native camera functions, simplifying audio-enabled installations.
- Fibre-Extended Network Runs: The integrated SFP slot supports fibre uplinks where camera locations are beyond standard Ethernet cable length limits.
- Infrastructure Upgrades on Existing Switches: Inline installation means high-power PoE can be added to specific ports without replacing a functional existing switch.
Why Choose the AXIS TU8003
The TU8003 addresses a specific gap in surveillance infrastructure: the need to power IEEE 802.3bt-class devices from network environments built around lower-power switches. Unlike a generic PoE injector, the TU8003 incorporates Axis Portcast technology, which means audio inputs and I/O connections wired to the midspan are addressable through the camera’s IP address directly in the video management system, without additional licensing or a separate network device. The SFP slot further distinguishes it from basic injectors by supporting fibre uplinks for long-distance runs. With a universal 100-240V AC input and support for desktop, shelf, or rack mounting, it integrates cleanly into professional AV and security rack builds. Available through Security Wholesalers, the TU8003 is a purpose-built Axis accessory designed to complement high-power Axis camera deployments rather than serve as a generic PoE solution.
Buyer Decision Tips
Buyer Tip: Confirm that your target Axis camera actually requires IEEE 802.3bt Type 4 power before specifying the TU8003. Cameras drawing under 30W are already served by standard 802.3at PoE switches, and the TU8003 is best justified where Portcast audio/I/O integration or fibre uplink support is also needed. If only basic high-power PoE is required and neither Portcast nor SFP is relevant to the site design, a simpler 802.3bt injector may suit the budget better.

Ideal Use Cases
PTZ Camera Installations
High-power Axis PTZ cameras requiring up to 90W of PoE power are directly supported by the TU8003’s IEEE 802.3bt Type 4 output, removing dependence on a high-power switch at the rack.
Audio-Enabled Security Zones
Where microphones or I/O devices need to be integrated without additional network hardware, Portcast technology allows these connections to appear as camera-native functions within the VMS, reducing system complexity.
Long-Distance Camera Runs via Fibre
The integrated SFP slot allows the TU8003 to bridge fibre and copper segments, making it suitable for cameras installed at distances that exceed the standard 100-metre Ethernet cable limit in large facilities or campus environments.
Existing Switch Infrastructure Upgrades
Installed inline between an existing lower-power switch and a high-power camera, the TU8003 adds 802.3bt PoE capability on a per-port basis without requiring a full switch replacement, controlling upgrade costs in staged rollouts.
Choosing the Right Model
- Choose this model if: Your Axis PTZ or high-power camera requires IEEE 802.3bt Type 4 power delivery, and you also want to route microphone or I/O signals through the same network connection using Portcast, or need a fibre uplink via SFP without adding another switch.
- Choose a different model if: Your camera draws 30W or less, in which case a standard 802.3at PoE switch port is sufficient and a dedicated midspan adds unnecessary cost. Similarly, if Portcast audio integration is not required and fibre connectivity is not needed, a lower-specification 802.3bt injector may be more cost-effective for the installation.
FAQs
- What does the AXIS TU8003 do that a standard PoE switch cannot?
A standard 802.3at PoE switch is limited to 30W per port, which is insufficient for high-power Axis PTZ cameras. The TU8003 supplies up to 90W per the IEEE 802.3bt Type 4 standard, and also adds Portcast audio and I/O integration plus an SFP fibre uplink port, none of which are typically available on a standard switch port.
- Does the TU8003 require any software configuration to use Portcast features?
Portcast technology presents audio and I/O connections through the camera’s existing IP address, so they appear as native camera functions within compatible video management systems. No additional VMS licences are required to access these interfaces, though the connected Axis camera must support Portcast for the feature to operate.
- What type of audio input does the TU8003 support via Portcast?
The TU8003 supports both digital and unbalanced microphone inputs through its Portcast interface. These signals are then transmitted over the same Ethernet connection as the camera’s video stream, avoiding the need for a separate audio cable run back to the recording system.
- How is the TU8003 installed in an existing network?
The TU8003 is inserted inline between the existing network switch and the high-power camera. The switch connects to the data-in port, and the camera connects to the PoE output port. The midspan injects power onto the cable while passing the network signal through, requiring no changes to the upstream switch configuration.
- Can the TU8003 be used with non-Axis cameras or third-party PoE devices?
The 90W IEEE 802.3bt Type 4 PoE output is a standards-based function and will deliver power to any compliant 802.3bt device. However, Portcast audio and I/O integration is an Axis-specific technology and will only function with compatible Axis cameras and devices.
- Where can I purchase the AXIS TU8003 in Australia?
