Why Choose the AXIS D3110 Mk II
The AXIS D3110 Mk II is ideal for customers who need to connect non-visual sensors and audio devices into a network video system without replacing existing cameras or infrastructure. Its eight supervised configurable I/Os can be used with devices such as door contacts, panic buttons, smoke detectors, temperature sensors, motion sensors and glass break detectors, helping trigger alerts and events based on real-world conditions. The two audio inputs and one audio output add sound awareness and communication capability, while VAPIX, MQTT and SIP support make it flexible for automation, security, access control and third-party integrations.
Key Capabilities
Eight Supervised Configurable I/Os
The AXIS D3110 Mk II includes eight supervised configurable input/output ports, allowing a broad range of sensors and external devices to be connected to the surveillance system. This helps link physical events such as door openings, alarms, motion detection, or environmental changes to video and audio workflows.
RS485/RS422 and Relay Integration
The RS485/RS422 port and relay support make the hub useful for connecting serial devices and external equipment into an Axis ecosystem. This provides additional flexibility for access control, automation, alarms, legacy device integration, and site-specific control workflows where standard camera I/O is not enough.
Audio Input and Output Support
With two audio-in ports and one audio-out port, the hub can add audio capability to systems that need microphones, speakers, or two-way communication. Voice enhancement, automatic gain control and equalisation support help improve usability for scene awareness, announcements, event verification, and security response.
AXIS Audio Analytics Included
AXIS Audio Analytics is preinstalled, allowing the hub to notify users when relevant audio events occur even if there is no visual indication. This adds another layer of awareness for environments where sounds such as shouting, breaking glass, alarms, or sudden noise changes may indicate an incident.
Secure and Flexible Network Integration
VAPIX, MQTT and SIP support make the AXIS D3110 Mk II highly adaptable for Axis systems, IoT workflows, communication platforms, access control and automation. Axis Edge Vault helps protect the device and sensitive information with hardware-based cybersecurity and certified secure key storage.
Key Features
-
Eight Supervised I/O Ports: The eight supervised configurable I/Os allow external sensors and devices to be connected to the surveillance system. This is useful for door switches, motion sensors, smoke detectors, temperature sensors, glass break detectors, panic buttons, access control triggers and other site-specific security inputs.
-
RS485/RS422 Port: RS485/RS422 support allows compatible serial devices to be integrated into the system. This gives installers additional flexibility when connecting external control devices, automation equipment, legacy interfaces, access control components, or site-specific hardware that requires serial communication.
-
Relay Output: The built-in relay allows the hub to control or trigger connected external devices as part of an event workflow. This can be used for alarms, lights, door equipment, sirens, access-related outputs, or other compatible devices depending on system design and electrical requirements.
-
Two Audio Inputs and One Audio Output: The hub supports two audio-in ports and one audio-out port, allowing microphones and speakers to be added where audio capability is required. This can support two-way communication, audio verification, announcements, incident response and sound-based awareness beyond video.
-
AXIS Audio Analytics Preinstalled: AXIS Audio Analytics can detect relevant audio events and help trigger alerts even when nothing obvious is visible on camera. This is useful in sites where sound can provide early warning, such as glass break events, loud voices, alarms, machinery changes or sudden noise increases.
-
VAPIX, MQTT and SIP Integration: Support for VAPIX, MQTT and SIP allows the AXIS D3110 Mk II to integrate with Axis products, automation platforms, IoT systems, audio workflows and communication systems. This makes it flexible for both security and operational event handling across complex installations.
-
PoE or DC Power: The device can be powered using Power over Ethernet or 10–28 V DC, giving installers flexibility depending on the available infrastructure. PoE helps simplify cabling by carrying power and data through one network connection, while DC power provides an alternative for cabinet-based installations.
-
Compact DIN-Rail Friendly Design: The compact form factor is suitable for installation in cabinets, equipment rooms and control panels. AXIS T91A03 DIN Rail Clip A is recommended for DIN rail mounting, while AXIS TD3901 Strain Relief can support secure cable management in more demanding installations.
-
microSD Storage Support: microSD, microSDHC and microSDXC card support provides local storage flexibility for supported use cases. This can be useful for event handling, analytics, system support or applications where local storage is part of the project design.
-
Axis Edge Vault Cybersecurity: Axis Edge Vault helps safeguard the device and protect sensitive information from unauthorised access. It includes FIPS 140-3 Level 3 certified secure cryptographic key storage and operations, supporting stronger cybersecurity practices for professional network security systems.
