i-PRO WV-PM500 Compact Microphone Unit
The i-PRO WV-PM500 is a compact microphone unit engineered to extend audio capture capabilities to compatible i-PRO IP cameras and network surveillance systems. Built to operate reliably in demanding field conditions, this accessory delivers real-time audio documentation alongside video evidence — a critical requirement when incident investigation, compliance recording, or access control verification depends on both visual and audio records.
Key Features
- IP65 Environmental Rating: Dust-tight and water-resistant protection means the WV-PM500 won't fail under direct spray, splash, or dust-laden environments — a serious consideration if you're deploying in loading docks, outdoor parking structures, or industrial zones where washdown or high-pressure cleaning is routine.
- Day/Night Audio Operation: Continuous 24/7 audio capture, independent of lighting conditions. Unlike passive audio solutions, the unit maintains consistent audio quality whether the scene is in daylight or infrared illumination — important for perimeter monitoring or facilities that operate around the clock.
- ONVIF Standard Compatibility: Integrates into multi-vendor surveillance architectures without proprietary driver dependencies. This means if you've standardized on ONVIF-compliant VMS platforms, the WV-PM500 plugs into your existing camera management workflow without custom integration work.
- Compact Form Factor: Minimal footprint reduces visual prominence and installation complexity. In retail or office settings where aesthetic discretion matters, the compact size allows mounting in or near camera housings without creating additional visual clutter or requiring separate conduit runs.
- Network-Ready Audio Delivery: Streams audio over IP directly into your surveillance recorder or VMS — no separate analog audio lines, no balanced/unbalanced converters. This simplifies cabling on large-scale deployments and eliminates the isolation and noise-susceptibility issues that plague long analog runs.
- Android OS Compatibility: Supports remote monitoring and control from mobile devices running Android, enabling field verification or real-time audio monitoring from your phone or tablet without requiring a dedicated workstation.
Integration & Compatibility
The WV-PM500 integrates seamlessly with network video recorders and ONVIF-compliant VMS platforms. When paired with compatible i-PRO cameras, audio and video streams are time-synchronized and recorded as a single evidence package — eliminating the lip-sync and timing mismatches that occur when audio and video originate from separate systems. Because the unit connects over IP, you avoid the grounding loops and RF interference common to analog audio circuits in long-distance deployments.
Deployment Contexts
The WV-PM500 performs well in retail loss prevention (capturing transaction disputes or employee incidents), office perimeter monitoring (vehicle access verification), warehouse receiving areas (package damage documentation), and outdoor property boundaries (intrusion detection with acoustic witness). The IP65 rating makes it suitable for uncovered loading docks, rooftop equipment access points, and external stairwells where rain or spray exposure is expected. Indoor deployments in climate-controlled spaces require no special consideration beyond standard surveillance mounting practice.
When to Choose a Different Model
If your deployment requires submersion-rated audio (wet-pit monitoring, underwater perimeter work), evaluate higher IP-rated alternatives — the WV-PM500's IP65 rating handles rain and spray, but not sustained water immersion. If directional audio capture or noise rejection is mission-critical, consult the microphone specification details in the datasheet to confirm pickup patterns and sensitivity thresholds align with your acoustic environment.

The i-PRO WV-PM500 is a straightforward audio accessory — no surprises, no exotic features. It does what a compact microphone should: deliver IP65-rated, ONVIF-compliant audio from a form factor that doesn't dominate your camera housing. If you're building a multi-camera surveillance network and need synchronized audio evidence without the cabling and isolation headaches of analog circuits, this is a solid fit.
Technical Highlights:
- IP65 Sealing: Eliminates moisture-related audio failures in outdoor or wet-environment mounts. No desiccant cartridge or potting compound to maintain — sealed and done.
- ONVIF Standardization: Cuts integration time in standards-based VMS deployments. No vendor lock-in, no firmware surprises when you upgrade your recorder.
- Day/Night Continuous Operation: Audio doesn't drop or degrade when the scene transitions to IR illumination — a small detail that prevents false gaps in your incident record.
Deployment Considerations:
- IP65 is splash and spray resistant, not submersion-rated. If you need audio from wet-pit monitoring or similar submerged applications, this isn't your solution.
- Verify microphone sensitivity and pickup pattern match your acoustic environment — use the datasheet to confirm frequency response and directional characteristics before deploying in high-ambient-noise zones.
Realistic use case: loss-prevention audio in a retail warehouse. You've got a dozen fixed cameras, three of which need audio to capture cross-dock disputes. IP65 durability covers accidental washdown in the receiving area, ONVIF integration avoids custom coding, and day/night operation means you're recording continuously without audio dead zones at shift changes. The WV-PM500 handles that deployment cleanly.
Frequently Asked Questions
Q: Is the WV-PM500 compatible with non-i-PRO cameras?
A: Yes, via ONVIF standard compatibility. Provided your camera or NVR supports ONVIF-compliant audio input, the WV-PM500 will integrate. Consult your camera or recorder documentation to confirm ONVIF audio support before purchase.
Q: Can the WV-PM500 be mounted outdoors year-round?
A: The IP65 rating handles rain, spray, and dust. It's suitable for outdoor mounting in most climates. In extreme cold (below -10°C) or high-humidity condensing environments, verify the datasheet for operating temperature and humidity ranges to avoid audio quality degradation.
Q: What power source does the WV-PM500 require?
A: The product datasheet will specify power delivery method — PoE, 12VDC, or other. Confirm with your specific camera or recorder model that its audio input supports the WV-PM500's power requirements before installation.
Q: Does the WV-PM500 support two-way audio or only recording?
A: The unit is described as a microphone input device. For two-way capability (microphone + speaker), confirm with the datasheet whether bidirectional audio is supported, or consult your VMS documentation for audio output capability.
Q: How do I integrate the WV-PM500 with my Milestone XProtect or Axis Camera Station system?
A: Because the WV-PM500 is ONVIF-compliant, it integrates into any ONVIF-compatible VMS (Milestone, Axis Camera Station, and most third-party recorders). Add the camera or recorder to your VMS, enable ONVIF audio discovery, and the WV-PM500 will appear as an audio input. Refer to your VMS documentation for audio input configuration steps.
Q: Is there a warranty on the WV-PM500?
A: Warranty terms are specified in your purchase documentation and i-PRO's standard product warranty. Contact the distributor or check the product datasheet for warranty period and coverage details.
