JSD54902

Product Overview
This premium M12 mount fixed focal lens (PN: JSD54902) is specifically engineered for 1/2.5-inch sensors, distinguishing itself with an ultra-fast F1.0 aperture for superior low-light capabilities. With a 4mm focal length, it provides a versatile 88° field of view, making it an excellent choice for 24/7 security surveillance and monitoring in challenging lighting environments. Featuring 4MP resolution, this "Starlight" class lens ensures bright, clear imaging and vivid color retention even in near-darkness, significantly outperforming standard lenses in night vision applications.

Key Features & Benefits

F1.0 Super Large Aperture: The ultra-wide F1.0 aperture maximizes light intake, delivering exceptional "Starlight" night vision performance and reducing image noise in low-light conditions without relying heavily on IR LEDs.

4MP HD Resolution: Optimized for high-definition sensors, providing sharp 2K imaging (up to 4 Megapixels) to capture essential details for security and identification.

Versatile 88° FOV: Offers a wide, standard viewing angle that balances broad area coverage with object detail, ideal for hallway monitoring, entrance security, and general room surveillance.

Optimized for 1/2.5" Sensors: Designed with a specific image circle to perfectly match 1/2.5" format sensors, ensuring full sensor utilization and consistent brightness from center to edge.

Compact Integration: Features a standard M12 thread and a Total Track Length (TTL) of 19mm, allowing for seamless integration into compact security cameras and smart home devices.

Standard Optical Distortion: With distortion controlled at <-10%, the lens provides a natural wide-angle perspective suitable for general CCTV and monitoring tasks where situational awareness is key.
