Product Description
Product Overview
The PL285 is a professional 8MP ultra-wide IR fisheye lens tailored for 1/2.5” IMX317 and 1/3” OV4689 image sensors, supporting stable 4K high-definition video output. Featuring an ultra-wide 210° full-directional field of view, this lens delivers seamless 360° panoramic coverage with zero monitoring blind areas, perfectly adapting to panoramic monitoring and portable DV visual capture scenarios.
Adopting premium 6G full-glass optical structure with integrated IR night vision function and multi-layer anti-reflection coating, this lens features fixed F2.0 aperture, low optical distortion and optimized CRA parameters. It adopts a compact mini body design and standard M12×P0.5 universal thread mount, with stable industrial-grade optical performance. Custom processing services are supported to meet personalized equipment matching and batch customization demands for security and portable visual devices.
Core Features & Selling Points
1. 8MP High Definition & True 4K Video Performance
Fully optimized for 1/2.5” and 1/3” high-definition sensors, the lens supports 8-megapixel high-resolution image acquisition and fluent 4K dynamic video output. It restores rich scene details and natural colors, presenting delicate and high-clarity footage that meets high-standard panoramic monitoring and video recording requirements.
2. 210° Full-Directional Blind-Spot-Free Panoramic Coverage
Provides a complete 210° ultra-wide viewing angle on horizontal, vertical and diagonal axes. It covers a far larger scene range than conventional wide-angle lenses, realizes single-lens full-area panoramic coverage, effectively eliminates monitoring dead zones, and reduces overall equipment deployment costs.
3. 6G Full-Glass + Integrated IR Night Vision Structure
Built with 6 groups of high-precision full-glass optical elements and professional IR infrared compensation structure, equipped with multi-layer anti-reflection coating. The all-glass structure ensures high light transmittance, strong structural stability and long service life. The built-in IR function guarantees bright, clear imaging in low-light and dark environments, enabling 24-hour day and night continuous stable operation.
4. Fixed F2.0 Aperture for Sufficient & Stable Light Intake
Comes with fixed maximum and minimum F2.0 aperture, ensuring stable and sufficient light intake in daily and dim environments. It effectively improves low-light imaging brightness, avoids underexposure and dark frame issues, and maintains uniform and stable picture brightness in complex light conditions.
5. Low Distortion & Optimized CRA Optical Calibration
Precision optical design controls TV distortion below -13%, ensuring natural picture transition and minimal stretching deformation for panoramic scenes. The Chief Ray Angle (CRA) is strictly limited below 11°, perfectly matching the light-receiving characteristics of compatible sensors, reducing edge vignetting and light attenuation, and achieving uniform edge-to-edge imaging definition.
6. Ultra-Compact Body & Universal M12 Compatibility
Features ultra-small dimension of Φ27×19.36mm and 22.4mm short optical total length (TTL), lightweight and easy for embedded assembly. Standard M12×P0.5 thread mount is widely compatible with mainstream surveillance cameras, panoramic monitoring modules and portable DV equipment, supporting fast installation and replacement.
7. Flexible Focus Distance for Multi-Scenario Adaptation
The minimum focusing distance is 0.2m, supporting both close-range detailed image capture and long-distance large-area panoramic scene acquisition. It delivers excellent adaptability for indoor monitoring, panoramic recording and various visual collection scenarios.
Application Scenarios
1. Full-Area Panoramic Security Monitoring
Ideal for homes, offices, shopping malls, supermarkets, hotels and other indoor public spaces. The 210° ultra-wide panoramic view realizes one-lens full coverage, completely solves monitoring blind spot problems and improves overall monitoring efficiency.
2. 24/7 IR Day & Night Surveillance Systems
Benefiting from professional IR infrared optical design, the lens maintains clear imaging in dark and low-light environments. It supports round-the-clock uninterrupted visual acquisition, suitable for smart security systems and unattended indoor monitoring equipment.
3. Portable DV & Panoramic Video Devices
With 4K high-definition output and ultra-wide panoramic performance, it is widely applied to portable DV recording equipment, mini panoramic visual terminals and daily scene collection devices, delivering immersive full-scene panoramic footage.
4. Intelligent Visual Sensing & Collection Equipment
Stable optical parameters and high-resolution imaging quality perfectly match intelligent panoramic sensing modules, industrial full-scene detection equipment and embedded visual acquisition terminals for high-precision visual data collection.
