Axis 01575-001 Device Microphone A
The Axis 01575-001 is a professional omnidirectional microphone designed to retrofit audio recording capability into Axis IP cameras and network devices that have 3.5mm audio input ports but lack integrated microphones. It bridges a common gap in surveillance deployments where video alone is insufficient — adding synchronized audio for event verification, compliance recording, and real-time incident response without requiring hardware replacement.
Key Features
- Omnidirectional Pickup Pattern: Captures sound equally from all 360 degrees around the microphone. This means you get consistent audio coverage in open offices, retail spaces, and facility lobbies without needing to aim or reposition the mic. No audio blind spots when mounted above or beside the camera.
- Standard 3.5mm Connector: Connects directly to any Axis device with a 3.5mm audio input jack—no proprietary adapters, no USB converters, no power injectors. Installation is literally plug-and-play: insert the connector and the device auto-detects the audio source.
- Compatibility with Q35 and P33 Series: Works with Axis Q35 series indoor cameras and P33 series devices. When using the optional Axis TP3201 Recessed Mount, the 01575-001 can be mounted flush in ceilings or walls, keeping the form factor clean and vandalism-resistant in high-traffic areas.
- No External Power Required: The microphone draws minimal power through the audio connection itself. There's no separate 12V supply to run, no PoE+ splitter to deploy—simplifies cabling and reduces points of failure in the field.
- Audio Analytics Integration: Once connected, audio streams directly into your NVR or VMS alongside the video feed. Enables sound-based event rules: detect glass breaking, gunshots, screams, loitering conversations, or other acoustic signatures for faster response and secondary verification of incidents.
- Tool-Free Installation: Requires no soldering, crimping, or terminal blocks. Field techs can deploy this in minutes without specialist audio training. Ideal for retrofitting dozens of existing cameras across a campus or multi-site facility.
Integration and Compatibility
Audio input works with any Axis device sporting a standard 3.5mm jack and audio input support in its firmware. Verify your camera's spec sheet confirms audio input capability—not all Axis models include this port. Once connected, audio encodes in the same bitstream as video (typically AAC or G.726 depending on device), so your storage and bandwidth calculations remain unchanged. Most VMS platforms support Axis audio natively via ONVIF, so no special drivers or codec packs are needed.
The 01575-001 (often searched as 01575 001) pairs well with fixed dome or box cameras where a built-in microphone isn't practical. It's also suitable for retrofitting older camera models still in service—budget-friendly way to add audio without wholesale equipment refresh.
Frequently Asked Questions
Q: Does the Axis 01575-001 work with all Axis cameras?
A: No. It only works with Axis devices that have a 3.5mm audio input jack and audio input support enabled in firmware. Check your camera's datasheet to confirm the 3.5mm port is present. Q35 and P33 series are confirmed compatible; other series may vary.
Q: Can I use the 01575-001 in a noisy warehouse or factory?
A: Yes. The omnidirectional design captures all sound equally, so it will pick up speech, machinery, and ambient noise. If you need to filter high-frequency hum or machinery noise, that filtering is typically done in the VMS or NVR software post-capture, not in the microphone hardware.
Q: What's the range of audio capture?
A: Omnidirectional microphones don't have a specified 'range' like cameras do. Audio quality depends on proximity to the sound source and ambient noise levels. In a typical 15–20 foot office, normal conversation will record clearly. In a large echoing space, sound will be more distant. Position the microphone centrally for balanced coverage.
Q: Is the 01575-001 weatherproof for outdoor use?
A: No. The microphone is designed for indoor use. If you need outdoor audio, you'll require a weatherproof microphone enclosure or a microphone model rated IP66 or higher—check with the camera or mounting accessory manufacturer for recommendations.
Q: Does the microphone require audio licensing or subscription?
A: No. Once installed, audio recording and storage are handled by your existing NVR or VMS. Some VMS platforms may offer optional audio analytics add-ons (speech recognition, gunshot detection), but the baseline audio capture and playback are included.
Q: Can I daisy-chain multiple Axis 01575-001 microphones to one camera?
A: No. Each Axis device typically has a single 3.5mm audio input jack. Only one microphone can be connected directly. If you need multi-location audio, deploy separate microphones on separate cameras.

The 01575-001 fills a real gap in retrofit deployments. Many mid-range Axis cameras—especially older Q35 and P33 domes—were built without integrated mics, but they have the 3.5mm jack and firmware support waiting to be activated. This microphone unlocks that capability without forcing a hardware swap. The omnidirectional pattern means you aren't buying a second tool to solve a directional-coverage problem; one unit covers the full 360° audio space around its mounting point.
Technical Highlights:
- 3.5mm Standard Connector: No proprietary connectors, no audio over Ethernet workarounds. Plug directly into the camera's audio input jack. Simplifies field support and reduces spare-parts complexity.
- No External Power Draw: Audio input is passive in most Axis devices—the microphone pulls what little power it needs from the audio line itself. Zero impact on your PoE switch power budget or camera battery drain if you're working with mobile units.
- Omnidirectional + Recessed Mount Option: Pair with the Axis TP3201 to mount flush in a ceiling or wall soffit. Omnidirectional design means you don't lose audio quality when the mic is above, beside, or at an angle to the camera lens—both devices capture the same spatial audio.
Deployment Considerations:
- Audio Input Port Verification is Critical: Not all Axis cameras have a 3.5mm audio input jack. Before ordering, physically check the device or pull the datasheet. Confusing audio output (line-out) with audio input is a common mistake that delays installation.
- Codec and Bitrate Impact is Minimal: Audio typically adds 64–128 kbps to your stream depending on codec (AAC vs. G.726). Storage and bandwidth impact is negligible compared to video, but verify your NVR has audio recording enabled in the channel settings—it's often disabled by default.
- Placement Matters for Clarity: Even though the microphone is omnidirectional, mounting it away from strong HVAC vents, machinery hum, or electrical noise sources improves usable audio quality. In retail or office environments, ceiling-mount centrally for best pickup of normal conversation.
Best suited for office security, retail point-of-sale verification, conference room incident documentation, and facility access-point monitoring where synchronized video-plus-audio creates stronger evidentiary records than video alone. If your deployment requires directional audio (e.g., pointing a mic at a specific speaker across a large room), you'll need a cardioid or shotgun microphone instead—outside the scope of the 01575-001.
