Compact 4 megapixel M12 lens built for board cameras and module applications Key features and specifications Lens interface: M12 interface for direct mounting to M12 camera modules and boardlevel sensors Resolution: 4 megapixels for clear, detail imaging Focal length: 4.0mm, providing a midwide field of view suitable for general purpose imaging F number: F2.0 to improve lowlight performance and capture more scene detail Optical back focal length: 7.67mm to match sensors and ensure correct focus when installed Why this lens matters Capture finer detail: The 4 megapixel resolution supports sharper images for identification, measurement, and quality checks. Better lowlight capability: The F2.0 aperture collects more light than highernumber lenses, improving exposure in dim environments without changing the sensor. Easy integration: The M12 interface is a common, compact mount used across many board cameras and modules, making installation quick and reliable. Precise alignment: The specified 7.67mm optical back focal length ensures proper sensor spacing and focus when paired with compatible camera modules. Performance and compatibility Function: Designed for video and still imaging where compact size and image quality are required Compatibility: Works with cameras and modules that accept M12 lenses and use the specified optical back focal length Size and form factor: Small M12 mount makes it suitable for embedded and tightspace installations Optical quality: Optimized focal length and aperture balance field of view and light gathering for general surveillance, inspection, and machine vision tasks Practical applications Indoor and outdoor surveillance: Install on compact CCTV or IP camera modules to capture clearer facial and object detail in corridors, retail areas, and office spaces. Industrial inspection and automation: Use on board cameras for production line monitoring, component inspection, and robotic vision where resolution and reliable focus are required. Robotics and unmanned systems: Fit to drone or mobile robot camera modules for navigation, mapping, and situational awareness in constrained payload environments. Installation tips Confirm your camera module accepts M12 lenses and supports the specified optical back focal length to achieve correct focus. For results in low light, pair with a sensor that has suitable sensitivity and exposure control. Test focus after mounting and secure the lens to prevent movement in vibrationprone applications. What sets it apart Combines a compact M12 mount with 4 megapixel resolution and an F2.0 aperture for a practical balance of size, image detail, and lowlight performance. The specified 7.67mm optical back focal length provides predictable focus behavior when integrated into compatible camera modules. Technical summary Lens interface: M12 interface Resolution: 4 megapixels Optical back focal length: 7.67mm Focal length: 4.0mm F number: F2.0
