Portcast interface for adding two-way audio and digital I/O to compatible Axis network cameras without requiring a separate IP address

The AXIS T6101 Mk II Audio and I/O Interface 02553-001 is a portcast device designed to add two-way audio and configurable digital I/O connectivity to supported Axis network cameras that do not already provide the required connections directly.

Using Axis portcast technology, the interface transfers audio and I/O communication digitally over the network cable between the camera and the interface. The connected camera retains its existing IP address, so the T6101 Mk II does not require a separate network identity for normal supported operation.

The interface can be positioned between the Ethernet switch and compatible Axis camera, allowing microphone, audio output and I/O connections to be placed closer to where they are required.

What Is Axis Portcast?

Portcast is Axis technology designed to add connectivity to supported cameras through an interface positioned between the camera and network switch.

Rather than operating as another independent network camera or audio endpoint, the T6101 Mk II adds its audio and I/O functionality to the supported camera connection.

This can help simplify:

• Network addressing
• VMS integration
• Audio/video association
• Physical placement of ports
• External sensor connectivity

Axis states that supported installations do not require an additional IP address or separate VMS license for the interface.

Axis lists event actions including external output activation and event triggers from supervised external inputs.

PoE Connectivity

The T6101 Mk II uses Power over Ethernet.

PoE Input: RJ45 10BASE-T / 100BASE-TX

PoE Output: RJ45 10BASE-T / 100BASE-TX

PoE Standards:
IEEE 802.3af / 802.3at Type 1 Class 2 or Class 3, or IEEE 802.3at Type 2 Class 4 depending on the connected camera requirements.

The interface forwards power to the connected camera.

Axis notes that some camera combinations may require an additional compatible midspan to provide sufficient power.

Connectors

PoE In: RJ45

PoE Out: RJ45

I/O: 4-pin 2.5 mm terminal block

Audio Input: 3.5 mm mic/line input

Audio Output: 3.5 mm line output

These ports allow audio and external I/O hardware to be located near the desired installation position rather than necessarily at the camera body itself.

Installation

Axis describes the T6101 Mk II as a plug-and-play portcast interface installed between the network switch and compatible camera.

The datasheet specifies supported placement along the connection up to 100 m / 330 ft, subject to the network and camera installation requirements.

A typical architecture is:

PoE Switch / Midspan → AXIS T6101 Mk II → Compatible Axis Camera

The microphone, line output and external I/O devices connect to the T6101 Mk II.

Compatible Cameras

Axis currently maintains a broad compatibility list covering:

• Bullet cameras
• Dome cameras
• Modular cameras
• Onboard cameras
• PTZ cameras

Secure boot

The security of a surveillance installation still depends on the camera, network configuration, firmware management and access-control policies.

Operating Conditions

Operating Temperature: -40°C to 50°C

Operating Humidity: 10–85% RH, non-condensing

Storage Temperature: -40°C to 65°C

The T6101 Mk II should nevertheless be installed according to Axis environmental and mounting requirements. The interface itself should not automatically be treated as an outdoor exposed device simply because its operating temperature range is broad.

Dimensions and Weight

Dimensions: 89 × 63 × 29 mm
