Axis 0639-001 P3905-R 1080p Mobile Network IP Camera PoE Digital PTZ

The Axis Communications AXIS P3905-R (part number 0639-001) is a high-performance mobile network IP camera engineered specifically for video surveillance in demanding transit and emergency-vehicle environments, including buses, trains, subway cars, and emergency response vehicles. Delivering full HDTV 1080p resolution at up to 1920×1080, it combines a 1/2.8-inch progressive-scan RGB CMOS sensor with digital PTZ, Wide Dynamic Range, and a proprietary Traffic Light mode that improves color differentiation of traffic signals in very low-light conditions. The camera is built to endure the continuous mechanical stress of mobile deployment—vibrations, shocks, bumps, and wide temperature swings from -30 °C to 60 °C—while an active tampering alarm monitors for blocking or spray-painting attempts. Power over Ethernet (IEEE 802.3af/802.3at Type 1 Class 2) condenses installation to a single cable run, and a shared physical interface with the preceding AXIS M31-R Series allows straightforward in-place upgrades of existing installations.

Key features & benefits

• HDTV 1080p Progressive-Scan Imaging — A 1/2.8-inch progressive-scan RGB CMOS sensor captures full 1920×1080 resolution at 30 fps across all supported resolutions, producing sharp, artifact-free images of moving objects in transit corridors.
• Traffic Light Mode — A dedicated image-processing mode improves color distinction of traffic lights in very dark scenes, a critical capability for in-cab and forward-facing vehicle installations.
• Wide Dynamic Range — Built-in WDR dynamic contrast technology handles scenes with extreme variations in brightness—such as tunnel entrances and exits—maintaining usable image quality throughout the exposure range.
• Digital PTZ with Preset Positions and Guard Tour — Electronic pan, tilt, and zoom with configurable preset positions and guard-tour capability allows operators to monitor specific zones of interest without any mechanical moving parts, improving reliability in high-vibration environments.
• Active Tampering Alarm — On-camera intelligence continuously monitors the video stream and triggers an alarm when tampering attempts such as lens blocking or spray-painting are detected, supporting uninterrupted surveillance integrity.
• Single-Cable Power over Ethernet Installation — IEEE 802.3af/802.3at Type 1 Class 2 PoE delivers both power and video over one Ethernet cable, simplifying installation in vehicle cable trays and reducing points of failure.
• On-Board Edge Storage — A microSD/microSDHC/microSDXC slot supports cards up to 64 GB, enabling local pre- and post-alarm video buffering and continuous recording independent of network availability.
• Wide Operating Temperature Range — Rated for -30 °C to 60 °C (-22 °F to 140 °F), the camera maintains full operation through the temperature extremes typical of outdoor vehicle exposure, cold-climate depot storage, and engine-bay heat.
• M12 Lens Mount with Adjustable Ball Housing — The M12 mount and ball-and-socket lens holder allow field-of-view adjustment and image leveling using the included lens tool, enabling fast, precise aiming without specialized equipment.
• Comprehensive Security and Authentication — Password protection, IP address filtering, HTTPS encryption, IEEE 802.1X network access control, digest authentication, and a user access log protect video streams and configuration access in shared-network vehicle deployments.
