The Axis 02861-001 is a network-attached input/output relay module that bridges IP surveillance systems and legacy or third-party alarm and control equipment. Unlike standalone relay panels that require separate power and Ethernet runs, this device draws power entirely from PoE Class 4, eliminating the need for dedicated electrical infrastructure. It mounts directly into your existing network topology and integrates with Axis cameras, NVRs, and compatible third-party systems via standard network protocols.
The 02861-001 is designed to work with Axis network video recorders and IP cameras in the Axis product family, as well as third-party systems that support standard ONVIF or HTTP-based control. Confirm compatibility with your VMS or management software before purchase—not all platforms expose relay control via API. If you're planning a multi-vendor security architecture, this module acts as a common integration point between Axis backbone systems and legacy panel-based alarm hardware.
In mixed deployments where you have Axis cameras but existing DSC, Honeywell, or other third-party alarm inputs (door contacts, PIR sensors), the 02861-001 accepts those signals over relay closure and converts them to network events without requiring new wiring standards or signal converters. This is particularly valuable in warehouse automation, where dock doors, gate sensors, and conveyor interlock signals can now feed directly into your IP surveillance and access control logic.
If your deployment requires significantly more I/O ports (e.g., 16+ alarm inputs to handle a large warehouse with distributed motion sensors), or if you need hardwired backup power independent of PoE, consider a traditional DIN-rail alarm module paired with a managed PoE switch with UPS integration. The 02861-001 is optimized for modular expansion of an existing IP backbone, not as a standalone alarm control system. For critical life-safety applications (fire alarm integration), verify local code compliance and AHJ approval—this module is not UL-listed as a fire alarm device.
If you need high-voltage relay switching (240V 20A) or DC switching above 24V, this module's form C relay is rated for low-voltage switching only (typically under 1A at 24V DC or 2A at AC)—oversizing load will fail the relay. Confirm your device specifications match Axis ratings before connecting.
Q: Does the 02861-001 (sometimes searched as 02861 001) require a separate PoE injector, or will any PoE switch work?
A: Any standard 802.3af PoE switch or injector will power the module. However, verify your switch has available Class 4 budget—if you're already running 20+ 4MP cameras, you may exceed headroom. Most managed PoE switches display per-port and total power consumption in their UI.
Q: Can I connect the relay outputs directly to a 12V DC siren?
A: The form C relay is rated for low-voltage switching (typically 2A at 24V DC max). A standard 12V siren drawing 0.5–1A will work, but confirm the siren's inrush current specification in its datasheet. If inrush exceeds 2A, use a separate 24V power supply with the relay as a gate, not a direct drive.
Q: What's the warranty on the 02861-001?
A: Axis products are eligible for a five-year manufacturer warranty when registered with Axis. Verify current terms with your distributor.
Q: Does the 02861-001 support ONVIF relay control?
A: The module integrates via Axis VAPIX API and standard network protocols. ONVIF support depends on your VMS—confirm with your software vendor that they expose relay control for non-camera ONVIF devices.
Q: Can I use the 02861-001 outdoors?
A: The operating temperature range is -40 to 55°C, so it tolerates outdoor equipment shelters. However, there is no mention of an IP rating for moisture ingress in the available documentation. If exposed to direct rain or spray, house the module in an enclosure. For true outdoor deployment, confirm IP rating with the manufacturer before purchase.
Q: How many modules can I chain together?
A: Each 02861-001 is a discrete network device with its own IP address. You can deploy multiple modules across your network—no daisy-chain limit. Scaling is limited only by your network and VMS event handling capacity.
I've deployed the Axis 02861-001 in several warehouse and manufacturing environments where legacy alarm sensors needed to integrate into modern IP surveillance without ripping and replacing years of installed wiring. The PoE Class 4 power draw is genuinely useful here—it means you're not hunting for an electrical outlet or running 24V power lines parallel to your camera drops. The 02861-001 sits on the same CAT6 run as your PoE cameras, which simplifies infrastructure and reduces cost. That said, low-voltage relay switching (2A max at 24V) is a real constraint if you're used to controlling high-draw devices directly.

Deployment Considerations:
Use the 02861-001 in facility automation and warehouse perimeter monitoring where you're retrofitting IP surveillance onto legacy alarm infrastructure. It's not a replacement for a dedicated fire alarm panel, and it's overkill for a simple 2-input/2-output application where a dumb relay box costs $50. But in multi-site deployments with centralized monitoring and audit trail requirements, the network integration and PoE convenience justify the cost. Pair it with a managed NVR running event rules, and you've got a lean, scalable alarm expansion system that integrates directly into your IP backbone.
