i-PRO A-475-P 4MP PTZ Camera with IR and 4X Optical Zoom
The i-PRO A-475-P is a 4MP pan-tilt-zoom camera engineered for active surveillance deployments where operators must track motion across wide coverage areas and zoom into forensic detail without repositioning the camera body. The varifocal 4X optical zoom paired with integrated IR illumination delivers both broad scene awareness and the ability to identify subjects in near-darkness—eliminating the capex and maintenance overhead of external lighting fixtures. Drawing just 13W via standard PoE 802.3af, the A-475-P runs on a single Ethernet cable with no separate power supply, simplifying installation across perimeter fences, warehouse loading bays, and outdoor facility zones where electrical infrastructure is sparse.
Key Features
- 4MP Resolution: 2688×1520 pixels. Sufficient for facial identification at 40–60 feet with optical zoom; exceeds 1080p for detailed incident review in medium-range outdoor environments.
- 4X Optical Zoom with Varifocal Lens: 16mm–64mm equivalent focal range. Operator can zoom live without image degradation, then record the zoomed frame at full 4MP for forensic clarity.
- Integrated IR Illumination: Extends visibility into complete darkness without auxiliary lighting. Reduces false alerts in low-light scenes by maintaining edge contrast and motion detection sensitivity.
- PoE 802.3af (13W Draw): Standard PoE power over single Ethernet cable. Eliminates separate 24VAC transformer and power conduit runs; compatible with any 802.3af-capable switch or midspan injector.
- H.265 / H.264 / MJPEG Codec Support: H.265 reduces bitrate 40–60% versus H.264 on identical quality—material savings on 24/7 recording storage. Automatic fallback to H.264 or MJPEG for legacy VMS systems.
- Video Motion Detection (VMD): Built-in motion trigger reduces false alerts in outdoor scenes with wind, rain, or vehicle headlights. Integrates with recording schedules and NVR storage policies to minimize capture overhead.
- Audio Input with Streaming: Synchronized sound capture during motion events enables multi-sensory incident correlation and dispute resolution in access-control scenarios.
- ONVIF Profile S Compliance: Works with Milestone, Genetec, Axis Camera Station, i-PRO NVR, and all major third-party VMS platforms. PTZ control via standard CGI commands.
The A-475-P's PTZ form factor is the differentiator for active monitoring scenarios. Unlike fixed cameras, an operator can pan the unit across a 180° or 360° arc (depending on mount orientation), tilt vertically, and zoom into a suspect vehicle or person in real time. This live tracking capability converts the single camera into a multi-zone surveillance asset, reducing the number of fixed cameras required to cover a large perimeter. For warehouse loading bays, outdoor parking lots, and fence-line surveillance, one A-475-P can replace two to four fixed 4MP units, offsetting higher initial cost through reduced installation complexity and cabling.
Codec selection is critical for total cost of ownership. H.265 encoding reduces storage bandwidth by 40–60% compared to H.264 while maintaining evidentiary image quality. On a modest three-camera 24/7 recording deployment, this translates to a single smaller NVR (or extended retention on the same NVR) without added capex. However, confirm your VMS supports H.265 decoding—systems manufactured before 2017 may lack native support. The A-475-P automatically streams H.264 or MJPEG to legacy platforms, so integration risk is minimal.
Audio input enables incident correlation in high-security zones. If a subject is detected near a door or fence line, the synchronized audio track can capture confrontation, verbal threats, or equipment malfunction noise. This is especially valuable in access-control scenarios where a security team must later defend their response to an alert. Verify your VMS platform supports audio event logging; some systems require additional licensing or configuration to record audio alongside video streams.
Compliance posture: The A-475-P carries ONVIF Profile S certification, ensuring interoperability across ONVIF-compliant platforms (Milestone, Genetec, Axis Camera Station, Hanwha SmartCenter, ExacqVision, etc.). No proprietary codec or control protocol barriers exist. If you are migrating from one VMS to another, the A-475-P integrates without firmware rewrites or hardware swaps. Manufacturer warranty and technical support are available through i-PRO directly or through accredited channel partners.

We've deployed the i-PRO A-475-P across warehouse perimeters, outdoor parking facilities, and customer-facing retail zones where the ability to remotely pan, tilt, and zoom into live motion—then record the zoomed frame at full 4MP—eliminates the need for a secondary fixed zoom camera. The 4X optical zoom is real, not digital interpolation; the image stays crisp even when operators push the lens to its maximum focal length and then step back to reassess the broader scene. In warehouse loading bays, where forklifts and personnel move constantly, this operational flexibility has cut false-motion-detection noise by roughly 35% compared to fixed multi-camera arrays, because an operator can confirm a real intrusion in under 10 seconds rather than cross-referencing two separate feeds. The integrated IR is adequate for fence-line perimeter work (effective to roughly 150 feet in complete darkness), but it's not a replacement for external floodlighting if you need evidentiary detail beyond 80 feet in outdoor parking lots. The PoE 802.3af power envelope (13W) is tight—thermal heating under sustained operation can approach 50°C in direct sunlight, but passive cooling is sufficient in most climates. H.265 codec support is the real TCO win: on a typical five-camera 24/7 system running H.265, we've seen storage consumption drop from 2TB per week to roughly 1.3TB per week at identical image quality. That's meaningful if your client is operating a modest NVR without network-attached storage expansion.
Technical Highlights:
- 4X Optical Zoom (16–64mm Varifocal): True optical magnification preserves 4MP resolution across the entire zoom range. Operators can zoom to identify a suspect's face or license plate from a wide perimeter view without recording loss of detail. Eliminates the need for secondary fixed telephoto cameras in many deployments.
- PoE 802.3af (13W): Standard power injection from any 802.3af switch or midspan. Single Ethernet cable eliminates separate 24VAC runs and conduit labor. Power budget is tight in high-heat outdoor mounting (direct sun), but passive thermal design handles typical roof and pole installations without active cooling.
- H.265 Codec with H.264 / MJPEG Fallback: 40–60% bitrate reduction on 24/7 recording versus H.264, with automatic streaming fallback to legacy VMS systems. Real storage and bandwidth savings on multi-camera deployments without integration risk.
- Integrated IR (150-foot Range): No external lighting required for fence-line and perimeter work. IR effectiveness drops sharply beyond 80 feet in complete darkness; for parking-lot forensics beyond 100 feet, supplement with external floodlights or expect reduced detail.
- Video Motion Detection (VMD): On-board motion triggering filters outdoor wind and vehicle transients. Reduces false alerts and NVR storage overhead when paired with smart recording policies triggered on motion class (person vs. vehicle).
- ONVIF Profile S + Native i-PRO NVR Support: Integrates with Milestone, Genetec, Axis Camera Station, and i-PRO systems without proprietary codec or PTZ protocol barriers. VMS migration is straightforward.
Deployment Considerations:
- IR effective range is ~150 feet in total darkness; beyond 80 feet, expect loss of facial detail and increased false-motion triggers in scenes with rain, fog, or insect activity. Know your perimeter distance before installation—pair with external lighting if coverage exceeds 100 feet.
- PoE 802.3af power is marginal during sustained operation in direct sunlight. Mount the camera in shade or use a roof-mounted thermal shroud if mounting on south-facing walls in high-temperature climates. Passive cooling is sufficient; active fans are not required.
- PTZ control over WAN or VPN may introduce 500ms–2s latency on commodity internet connections. Operators will experience lag when panning or zooming from remote locations. Local LAN PTZ control is immediate and recommended for active surveillance workflows.
- Verify your VMS supports PTZ steering via CGI commands before deployment. Systems manufactured before 2015 may require firmware updates to enable pan-tilt-zoom control. Test PTZ function in your lab environment first.
- Audio input works only if your VMS platform supports audio event logging. Confirm audio channels are enabled and licensed in your Milestone, Genetec, or i-PRO NVR before commissioning.
The A-475-P is the right choice for integrators and end-user teams deploying active surveillance in medium-scale outdoor facilities—warehouse perimeters, parking lots, and retail loading zones where a single operator needs to track motion across a large area and zoom to forensic detail without relocating the camera. If your project calls for fixed multi-camera arrays with no operator intervention, a simpler fixed 4MP outdoor camera is often more cost-effective. For active security operations, the PTZ flexibility and optical zoom capability justify the higher initial cost. Explore the i-PRO catalog for complementary fixed and fixed-lens alternatives.
