Product SKU: P3925-LRE
Product Overview
Exterior surveillance on buses, trains, emergency vehicles, and other transport platforms places far greater demands on a camera than a conventional building installation. Continuous vibration, mechanical shock, rain, dust, temperature changes, high-pressure cleaning, low light, and rapidly changing outdoor scenes must all be considered. The AXIS P3925-LRE is a compact 2MP network camera developed specifically for these demanding exterior onboard applications.
The camera delivers Full HD 1920 x 1080 video at up to 30 frames per second through a 6mm fixed lens offering a 56° horizontal field of view. AXIS Lightfinder produces usable colour footage in poor lighting, while Forensic WDR preserves important details when both bright and shadowed areas appear in the same image. Built-in OptimizedIR illumination provides visibility in complete darkness at distances of 20 metres or more, depending on the surrounding scene.
Electronic image stabilisation helps reduce the visible effects of vibration and movement, making the camera suitable for exterior mounting on moving vehicles and rolling stock. Its aluminium enclosure, AR-coated tempered glass window, and IP66, IP67, IP6K9K, and IK10+ ratings provide protection against dust, water, physical impact, demanding weather, and high-pressure cleaning. The camera also complies with transportation standards including EN50155 and EN45545-2.
Key Capabilities
Purpose-Built Exterior Onboard Camera
The AXIS P3925-LRE is specifically designed for exterior installation on buses, trains, emergency vehicles, and other transportation platforms. Its low-profile housing can be positioned near doors, vehicle sides, roof-mounted equipment, or other external areas requiring continuous video monitoring.
Full HD 1080p Imaging
The 1/2.9-inch progressive scan RGB CMOS sensor captures Full HD 1920 x 1080 video at up to 25 or 30 frames per second. A 720p capture mode is also available at up to 45 frames per second for applications where smoother motion recording is preferred.
Lightfinder and Forensic WDR
AXIS Lightfinder improves colour reproduction and detail in poor lighting. Forensic WDR balances scenes containing bright sunlight, reflections, deep shadows, headlights, platform lighting, and other difficult combinations that commonly occur around moving vehicles.
Built-In OptimizedIR Illumination
Power-efficient 850nm infrared LEDs provide night-time monitoring at distances of 20 metres or more, depending on the scene. The automatically removable infrared-cut filter enables true day and night operation, including video capture at 0 lux when the IR illumination is active.
Electronic Image Stabilisation
Electronic image stabilisation helps reduce visible shaking caused by vehicle movement, engine vibration, track movement, road surfaces, and wind exposure. This provides a more stable image for live monitoring and recorded incident review.
Transport-Grade Exterior Housing
The aluminium casing is rated IP66, IP67, IP6K9K, NEMA 250 Type 4X, and IK10+. An AR-coated tempered glass window protects the camera optics while supporting clear exterior imaging in demanding transportation environments.
Best For
- Bus Door and Side Monitoring: Provides an exterior view of vehicle doors and surrounding areas to assist drivers and operators when passengers are boarding or leaving the vehicle.
- Train and Rolling Stock Surveillance: Suitable for monitoring exterior doors, platforms, vehicle sides, coupling areas, and other external parts of rail vehicles.
- Pantograph Inspection: Can be installed on rolling stock to observe pantograph collector strips and identify visible wear, damage, or maintenance requirements.
- Emergency and Specialty Vehicles: Suitable for external surveillance on fire appliances, emergency response vehicles, mobile command units, and specialist fleet vehicles.
- High-Vibration Installations: Electronic image stabilisation and transport-industry testing make the camera suitable for locations where ordinary outdoor cameras may experience excessive image movement or mechanical stress.
Why Choose the AXIS P3925-LRE
A conventional outdoor dome or turret camera may be weather-resistant, but it is not necessarily designed for the continuous vibration, mechanical shock, temperature extremes, cleaning processes, and electrical conditions encountered on transportation vehicles. The AXIS P3925-LRE combines exterior environmental protection with dedicated transportation approvals, electronic image stabilisation, low latency operation, and rugged connector options.
Its 6mm lens and 56° horizontal field of view provide a more focused view than an ultra-wide interior camera, making it suitable for monitoring vehicle doors, side clearances, trackside areas, external equipment, and maintenance components. Optional 3.6mm and 8mm M12 lenses are also available when a wider or narrower field of view is required.
AXIS Zipstream supports efficient H.264 and H.265 video compression to reduce storage and network bandwidth requirements. Recordings can be stored on a compatible microSD card, sent to network-attached storage, or managed through an Axis or compatible third-party video management platform.
Buyer Decision Tips
Buyer Tip: Confirm whether your installation requires the RJ45 version or the rugged M12 connector version before ordering. The standard AXIS P3925-LRE uses an RJ45 connection, while the AXIS P3925-LRE M12 uses a rugged D-coded M12 connector commonly specified for transport and rolling-stock installations. Also confirm whether the standard 6mm lens and 56° horizontal view suit the required monitoring area.

Ideal Use Cases
Bus Door Surveillance
Mount the camera near an exterior passenger door to provide drivers and operators with a clear view of passengers, kerbs, platforms, and objects located close to the vehicle.
Train Exterior Monitoring
The rugged enclosure and transport approvals suit exterior monitoring on trains and rolling stock where the camera is exposed to weather, vibration, shock, and frequent cleaning.
Pantograph Condition Monitoring
A roof-mounted camera can be directed towards the pantograph assembly to assist with identifying visible wear and maintenance requirements on collector strips and associated equipment.
Emergency Vehicle Surveillance
Suitable for external monitoring on emergency and specialist vehicles where stable video, low-light performance, and resistance to road vibration are important.
Harsh Exterior Equipment Monitoring
The IP6K9K-rated enclosure can be considered for compatible exterior equipment applications involving dust, water exposure, physical impact, and high-pressure cleaning, subject to confirmation that the transportation-focused mounting design suits the project.
Choosing the Right Model
- Choose the RJ45 version if: The camera will connect to conventional Ethernet cabling and the installation does not require a dedicated transport-grade M12 connector. The applicable Axis part number is 02090-001.
- Choose the M12 version if: The project specifies a rugged D-coded M12 connection for vehicle, train, rolling-stock, or industrial transport installation. The applicable Axis part number is 02091-001.
- Choose the standard 6mm lens if: A focused 56° horizontal view is appropriate for vehicle doors, exterior equipment, or side monitoring.
- Consider an optional lens if: The standard view does not suit the scene. A compatible 3.6mm lens provides an 86° horizontal view, while a compatible 8mm lens provides a narrower 41° horizontal view.
FAQs
