Axis 01561-001 Digital Microphone
The Axis 01561-001 (often searched as 01561 001) is a professional omnidirectional microphone built to extend audio monitoring capabilities into existing Axis IP camera and network device deployments. Where video alone leaves gaps in incident documentation, audio capture fills them — critical in retail loss prevention, facility security, and multi-space oversight. This unit plugs directly into compatible Axis devices via ring power, eliminating a separate power supply and simplifying the bill of materials on already-stretched installations.
Key Features
- Omnidirectional Pickup Pattern: Captures sound equally from all directions — essential for open lobbies, warehouse floors, or multi-entrance retail spaces where directional mics would miss coverage zones. You won't get dead spots from backing toward a wall.
- 100-Meter Transmission Range: Audio travels up to 100 meters (328 feet) from the connected Axis device without active amplification or relay hardware. Matters in sprawling facilities where a single NVR or recording appliance sits distant from monitored zones — avoids the cost and complexity of mid-run audio distribution boxes.
- Ring Power Integration: Draws power directly from compatible Axis network devices with digital inputs and ring power support. No separate 12V transformer, no additional outlet, no second cable run. Reduces installation labor and footprint in cable trays.
- Dual Connectivity Options: Accepts both 3.5mm jack and audio terminal block connections. Gives installers flexibility: 3.5mm for quick temporary setups or lab testing; terminal block for permanent installations where solder-free, screw-down termination prevents accidental disconnects.
- Audio Quality for Security Documentation: Delivers clear, uncompressed audio capture suited to incident reconstruction. Speech intelligibility is preserved well enough for voice identification and transaction capture — critical for disputes over what was actually said.
- Compact Physical Form: Small footprint and mounting flexibility mean it integrates into spaces without drawing attention or occupying valuable real estate alongside the camera housing.
Integration & Compatibility
The 01561-001 pairs with Axis surveillance products and compatible third-party devices that expose digital audio input pins and can supply ring power. Before ordering, verify that your target Axis camera, video encoder, or appliance supports audio input on its connector spec sheet — not all models include audio I/O. Ring power is a specific feature; older or entry-level devices may not support it, which means you'd need an external power supply to operate the microphone.
Audio feeds directly into the recording device's stream; no separate codec or gateway needed. That simplifies architecture in small to mid-sized deployments but means you're reliant on the host device's audio buffer and storage planning. If you're recording at high frame rate or bandwidth-constrained, audio can compete for buffer space — plan accordingly.
Typical Deployment Scenarios
- Retail & Loss Prevention: Pair with IP cameras at POS terminals, storage areas, or self-checkout zones to capture transaction audio alongside video. Dispute resolution and investigative detail improve measurably.
- Warehouse & Logistics: Omnidirectional coverage in receiving or packing areas documents forklift operations, verbal instructions, and incident circumstances without requiring sight lines.
- Corporate Meeting Spaces: Meetings rooms and collaboration areas benefit from full-spectrum audio capture, supporting training recordings or security audits.
- Multi-Zone Facilities: Run multiple 01561-001 units on separate devices across a large space for zoned audio monitoring — lobby, corridor, back office — each feeding its own recording stream for post-incident review.
When to Choose a Different Approach
If you need directional audio (e.g., focusing on a single speech area while rejecting crowd noise), look for a cardioid or shotgun microphone variant in the Axis range — the 01561-001's omnidirectional design is a strength in open spaces but a weakness in noisy multi-source environments. If your facility's audio devices lack ring power or digital audio input, you'll need an external powered mixer or audio injector — not a limitation of the microphone itself, but a prerequisite you must confirm before committing to this model.
Frequently Asked Questions
Q: Will the 01561-001 work with any Axis camera?
A: No. The 01561-001 requires a compatible Axis device with a digital audio input port and ring power support. Check the target camera or encoder's datasheet for audio input specification before ordering.
Q: Does the microphone require a separate power supply?
A: Not if your Axis device supports ring power. The microphone draws power directly from the connected device via the audio cable. If the host device lacks ring power, you'll need an external power supply.
Q: What's the maximum distance between the microphone and the recording device?
A: Audio transmission is rated to 100 meters (328 feet) from the compatible Axis device without active amplification or repeaters.
Q: Can I use a 3.5mm cable or does it require the terminal block?
A: Either connection method works. The 3.5mm jack suits temporary or lab setups; the audio terminal block is preferred for permanent installations because screw-down termination resists accidental disconnects.
Q: Is the audio compressed during transmission?
A: Audio quality depends on the host device's recording format and codec. The 01561-001 itself outputs uncompressed audio; the recording device applies any compression as part of its stream encoding.

The Axis 01561-001 is a straightforward audio input solution that solves a real problem: you've got video coverage, but no sound. Ring power eliminates one integration hurdle, and the 100-meter range means you don't have to install a relay or powered mixer in the middle of a long cable run. But—and this is critical—it only works with Axis devices that explicitly support audio input and ring power. I've seen integrators spec this assuming compatibility only to find out at site visit that the selected camera lacks the port. Verify the host device's audio I/O pins before you quote it.
Technical Highlights:
- Omnidirectional Pattern: Equal pickup from all directions eliminates dead zones in open spaces. Tradeoff: in noisy multi-source environments (busy retail floor, warehouse shift change), you'll capture everything — which is sometimes what you want for incident reconstruction, but not ideal if you need speech isolation.
- 100-Meter Transmission Range: Avoids the need for powered repeaters or intermediate distribution boxes. Matters when your recording appliance sits distant from the monitored space — saves you hardware cost and cable management complexity.
- Ring Power Support: Power flows through the audio cable from the host Axis device. Prerequisite: the device must support ring power in its digital I/O pins. If it doesn't, you'll need an external 12V supply — check the host device spec before committing.
Deployment Considerations:
- Compatibility is the gating factor. The 01561-001 works only with Axis devices that have audio input and ring power. Don't assume older models or lower-cost lines support it — review the host device's pin-out diagram and audio I/O section of its datasheet.
- Ring power draw is minimal, but if you're already pushing the host device's power budget (especially on battery-backed or low-power cameras), adding the microphone means you need to revalidate total current draw and battery runtime.
Good fit: retail environments where every transaction and incident needs audio backup, logistics facilities capturing operational chatter and equipment noise, and corporate campuses requiring full-spectrum meeting room recording. Skip this if you need cardioid or shotgun pickup — Axis offers directional options in their microphone catalog.
