Marshall Electronics CV4812-8MP 12mm F1.8 8MP M12 Lens

Product Description

The Marshall Electronics CV4812-8MP is a 12mm fixed focal length M12-mount lens designed for 8-megapixel imaging applications in commercial camera systems. With an F1.8 maximum aperture, this lens allows more light onto the sensor, supporting clear image capture in lower-light environments. The M12 board-lens format is a compact, screw-mount standard common in security cameras, inspection systems, and machine vision setups. Installation is typically handled by AV integrators, security technicians, or surveillance system specialists working with board-camera or module-camera platforms.

This lens is suited for commercial camera accessory applications where an 8MP-compatible M12 lens is required. The 12mm focal length provides a narrower field of view than wide-angle alternatives, making it appropriate for longer-range identification or detail capture in corridor, doorway, or perimeter monitoring scenarios. It is sold as a single unit and is applicable to commercial surveillance and inspection installations requiring an M12 lens mount.

Key Features

• 12mm fixed focal length for medium-range detail capture
• F1.8 maximum aperture supports performance in reduced-light conditions
• 8MP image resolution compatibility for high-definition camera sensors
• M12 screw-mount format fits standard board-camera and module-camera housings
• Compact form factor suited for embedded and commercial camera installations

Compatibility

Designed as an OEM-style replacement or upgrade lens for commercial cameras using the M12 board-lens mount standard with 8-megapixel sensor platforms.

Installation Notes

Installation is performed by qualified AV or security system technicians. Power down the camera system before removing or installing any lens. The M12 lens threads directly into the camera board mount and should be tightened by hand to avoid cross-threading the mount. Verify back-focus adjustment after installation to confirm image sharpness across the intended field of view.
