Product Overview
Model: D3110
Who This Is For
When integrating multiple third-party devices into an Axis surveillance system is the priority, the AXIS D3110 Mk II Connectivity Hub fills a gap that cameras alone cannot cover. It is aimed at systems integrators, security installers, and commercial AV professionals who need to bridge door contacts, alarm inputs, PTZ serial control, and legacy RS485 devices into a single unified Axis ecosystem. The compact DIN-rail form factor means it sits cleanly inside an electrical cabinet or IDF alongside switchgear and patch panels, keeping the installation tidy and accessible. With 8 configurable I/O ports and RS485/RS422 serial support, it suits sites where a mix of input and output devices - barrier arms, sirens, card readers, PTZ cameras on serial control, or sensor arrays - need to terminate in one place and report back through a centralised Axis platform.
What This Device Actually Does
8 Configurable I/O Ports
Each port can be assigned as an input or output depending on what you are connecting. Door contacts, PIR sensors, relays, and alarm outputs can all terminate here, removing the need to run every sensor back to a camera's limited onboard I/O.
RS485/RS422 Serial Support
Native RS485 and RS422 interfaces allow the hub to communicate with PTZ cameras on serial control protocols, as well as intercoms, access control panels, and legacy serial devices that do not speak IP natively.
PoE Powered
The hub is powered via a single PoE network connection, which means no local 240V power supply is required at the cabinet. One Cat5e or Cat6 cable carries both data and power, simplifying installation inside comms rooms or smaller enclosures.
Compact DIN-Rail Form Factor
The DIN-rail mounting format is the standard for electrical and comms cabinets in commercial installations. The D3110 Mk II clips directly onto 35mm DIN rail, keeping the device secure, organised, and accessible for maintenance or reconfiguration.
Axis Ecosystem Integration
As a native Axis device, the D3110 Mk II appears directly in Axis Camera Station and AXIS Device Manager, allowing I/O events to trigger recording rules, alerts, and responses across the wider Axis system without third-party middleware.
Who Buys This Model
- Systems Integrators: Professionals building large Axis deployments who need a clean, cabinet-mounted termination point for sensors, door contacts, and relay outputs across a site.
- PTZ Installers: Technicians connecting serial-controlled PTZ cameras to an IP network where RS485 or RS422 bridging is required but camera-side serial ports are already in use or unavailable.
- Commercial Site Managers: Facilities teams expanding an existing Axis system to incorporate additional alarm inputs - perimeter fencing sensors, duress buttons, or environmental monitors - without adding more cameras.
- Retail and Industrial Electricians: Tradespeople specifying DIN-rail equipment for switchboard-based installations where a neat, snap-in Axis I/O module replaces ad hoc cabling workarounds.
Honest Assessment
The D3110 Mk II does one thing very well: it expands the I/O and serial connectivity of an Axis installation in a form factor that belongs in a comms cabinet. The 8 configurable ports give integrators genuine flexibility across a range of input and output device types, and RS485/RS422 support handles serial devices that most IP-only solutions cannot reach. PoE powering keeps the installation straightforward where a local power supply would otherwise add complexity. Where this device will not help is in providing video capture, analytics, or standalone operation - it has no camera function and is entirely dependent on an existing Axis network and management platform. It is also purpose-built for the Axis ecosystem; installations running third-party VMS platforms may find integration requires additional configuration or may not be fully supported. Available through Security Australia, the D3110 Mk II suits integrators already committed to Axis who need to extend peripheral connectivity at scale.
Before You Buy
Installer Note: Confirm that your PoE switch port can supply sufficient power for the D3110 Mk II before installation. Because the hub also drives output relays and connected serial devices, the PoE budget at the switch port needs to account for the hub's total load, not just the device idle draw. If the port is shared with high-demand equipment, consider a dedicated switch port or a PoE injector to avoid under-powering.
RS485 Wiring Note: RS485 is a differential bus topology - termination resistors at each end of the cable run are required for reliable communication, especially on runs exceeding 10 metres. Ensure the correct termination is applied at both the D3110 Mk II and the far-end serial device, and use shielded twisted-pair cable for the RS485 segment to reduce noise on industrial sites.
Quick Fit Check
- Good match if: You are expanding an Axis camera system and need additional alarm inputs or relay outputs in a cabinet-mounted device - the 8 configurable I/O ports and DIN-rail form factor are built for exactly this scenario.
- Good match if: Your site includes serial-controlled PTZ cameras or legacy RS485 devices that need to be bridged into an IP network managed through Axis Camera Station.
- You may need a different model if: Your project requires standalone video recording or edge-based analytics - a dedicated Axis camera or NVR is the appropriate product type for those functions, and Security Australia carries a full range of both.

Real-World Scenarios
How It Compares
- Choose this if: You need a dedicated, cabinet-mounted I/O expansion device with RS485/RS422 serial support that integrates natively into an existing Axis platform - the D3110 Mk II is purpose-built for this rather than using workarounds through camera onboard I/O ports.
- You may need a different model if: Your project requires video capture, edge analytics, or standalone recording alongside I/O management - a combined Axis camera with onboard I/O, or a dedicated NVR with alarm inputs, would be the more appropriate product type for those combined requirements.
- Pairs well with: Axis fixed cameras, Axis PTZ cameras on serial control, Axis access control hardware, and PoE managed switches with sufficient per-port PoE budget for the hub and its connected output loads.
Common Questions
-
Does the D3110 Mk II work as a standalone device without an Axis camera or NVR?
No. The D3110 Mk II is a connectivity hub that operates within the Axis ecosystem. It requires an Axis network infrastructure - typically Axis Camera Station or AXIS Device Manager - to configure I/O rules and respond to events. Without an Axis management platform, the hub has no standalone processing or recording function. -
Will this hub work for controlling a PTZ camera that uses RS485 protocol?
Yes. The D3110 Mk II includes RS485 and RS422 serial interfaces, which are the standard connection types for PTZ cameras using protocols such as Pelco-D and Pelco-P. This allows serial-controlled PTZ cameras to be integrated into an IP-based Axis system where a native IP PTZ is not available or not practical to deploy. -
How many devices can I connect to the 8 I/O ports simultaneously?
All 8 ports can be active at the same time. Each port is individually configurable as either an input or an output, so you can mix sensor inputs - door contacts, PIRs, loop detectors - with relay outputs for sirens, barrier arms, or locks, up to the total of 8 ports across the hub. Port assignment is managed through the Axis device interface. -
What PoE standard does the D3110 Mk II require?
The hub is powered via PoE. IEEE 802.3af is the base PoE standard and is compatible with the device. Confirm the available PoE budget on your switch port before installation, particularly if the hub is driving relay outputs with inductive loads that draw additional current at switching. A dedicated switch port is recommended for predictable power delivery. -
Is the DIN-rail format compatible with standard electrical cabinets used in Australian commercial installations?
Yes. The D3110 Mk II is designed for 35mm DIN rail, which is the standard rail profile used in Australian electrical switchboards, comms cabinets, and IDF enclosures. It clips directly onto the rail without additional mounting hardware, making it straightforward for electricians and data cabler to fit alongside standard switchgear and patch panels. -
Can I configure I/O events to trigger camera recording rules automatically?
Yes. Because the D3110 Mk II appears as a native Axis device in Axis Camera Station, any I/O event - a door contact opening, a sensor triggering, a duress button activating - can be used as the condition in an Axis event rule to start recording on one or more cameras, activate an output relay, or send an alert. This is configured within Axis Camera Station's rules engine without third-party middleware. The D3110 Mk II is part of the Security Australia range of Axis accessories and integration hardware.
