AXIS A9161 Network I/O Relay Module – Extension Module
The AXIS A9161 Network I/O Relay Module is a compact, high‑performance extension designed to expand the functionality of Axis network cameras and video encoders. It provides six configurable digital/analog input or output channels that can be used as relays, enabling seamless integration with building automation systems, security infrastructure, and industrial control networks.
Key Technical Specifications
- Operating Temperature: -40 °C to +55 °C (±20 °C tolerance) – suitable for harsh outdoor environments and indoor installations with extreme temperature variations.
- Relative Humidity: 20 %–85 % RH – ensures reliable operation in humid climates without condensation issues.
- Dimensions: Width 120 mm, Depth 35 mm, Height 178 mm – a slim profile that fits easily into standard Axis chassis or rack mounts.
- Power Supply: External DC input of 8–28 V (12/24 V nominal) – compatible with most industrial power supplies and camera power modules.
- Network Interface: Single RJ‑45 Ethernet port supporting IPv4, IPv6, HTTP, HTTPS, TLS, QoS Layer 3 DiffServ, FTP, SFTP, SMTP, Bonjour, UPnP, SNMPv1/v2c/v3 (MIB‑II), DNS, DynDNS, NTP, RTSP, RTP, TCP, UDP, IGMP, RTCP, ICMP, DHCP, ARP, SOCKS.
- Channel Type: Relay – each of the six channels can be configured as a digital input or output, allowing for versatile control schemes.
Design and Build Quality
The module is finished in a clean white (Blanco) chassis that matches the aesthetic of Axis products. Its robust construction weighs only 500 g, making it lightweight yet durable for long‑term deployment. The single RJ‑45 port is protected by an integrated locking mechanism to prevent accidental disconnection during operation.
Installation and Integration
Installing the A9161 is straightforward:
- Mount the module into a compatible Axis chassis or rack using standard screws.
- Connect the external DC power supply (8–28 V) to the designated input terminals.
- Attach an Ethernet cable from the RJ‑45 port to your network switch or router.
- Use the Axis web interface or configuration utility to assign each channel as an input or output, set trigger conditions, and define relay behavior.
The module’s firmware supports automatic discovery via UPnP and Bonjour, simplifying initial setup in complex networks. Once configured, the relays can be controlled remotely through standard HTTP/HTTPS requests or SNMP commands, enabling integration with third‑party building management systems.
Typical Use Cases
- Security Systems: Trigger alarms, activate sirens, or control access doors based on camera events.
- Building Automation: Manage HVAC units, lighting circuits, or power distribution panels from a central video management platform.
- Industrial Control: Interface with PLCs or SCADA systems to monitor process variables and actuate machinery.
- Remote Monitoring: Provide real‑time status updates of critical infrastructure via the network, allowing proactive maintenance.
Reliability and Compliance
The A9161 meets stringent industrial standards for temperature, humidity, and electromagnetic compatibility. Its firmware is regularly updated to support emerging protocols such as IPv6 and TLS 1.2/1.3, ensuring secure communication in modern networks.
Conclusion
With its compact size, extensive network protocol support, and flexible relay channels, the AXIS A9161 Network I/O Relay Module – Extension Module is an essential component for professionals looking to extend the capabilities of Axis cameras and encoders. Whether you’re building a sophisticated security system or integrating video surveillance into a broader automation platform, this module delivers reliable performance in demanding environments.
