Extra Info
Engineered for Onboard Environments
The P3925-R is purpose-built for use in vehicles and mobile installations. Its durable housing is IP66/IP67-rated for protection against dust and water, while the IK10 rating ensures impact resistance. Designed to meet the EN50155 standard, it operates reliably even when subjected to vibration, humidity, and wide temperature ranges, making it ideal for fleet surveillance.
Advanced Imaging in Any Light
With Lightfinder and Forensic WDR, the camera delivers exceptional image quality in low light and dynamic lighting scenarios. Whether it’s capturing a passenger entering a vehicle at dusk or identifying details through windshield glare, the footage remains detailed and balanced.
Smart Compression with Axis Zipstream
Axis Zipstream technology drastically reduces file sizes by focusing on important areas within the frame—like faces or license plates—while filtering out irrelevant background data. This ensures reduced storage costs without compromising video quality.
Flexible Installation & Integration
The compact form factor and included mounting options make it easy to install in tight or angled spaces. Plus, with support for both H.264 and H.265, it integrates smoothly into most modern VMS platforms and onboard storage systems.
