Pinhole Lens – CCL13037PMPR2

CCL13037PMPR2 Pinhole lens 1/3″ 3.7mm flat HD CCTV M12 mount lens for Covert hidden Surveillance

3.7mm 1/3″ M12 Pinhole Wide Angle Lens

This 3.7mm M12 pinhole lens is designed for compact camera modules that require a discreet optical configuration, wide scene coverage, and flexible installation in space-constrained devices. Featuring a 1/3″ image format, 92° diagonal FOV, megapixel resolution, F2.5 fixed aperture, and 0.1m minimum object distance, it is well suited for embedded surveillance, access control, smart security devices, and compact monitoring systems.

With an M12X0.5 mount, fixed 3.7mm focal length, and manual focus, this pinhole lens can be integrated into small camera housings where conventional larger lenses may be difficult to install. The compact optical configuration makes it a practical choice for applications requiring a wider viewing area while maintaining a small camera footprint.

M12 Pinhole Lens Applications & Compatible Devices

Core Application Scenes

This M12 pinhole lens is primarily designed for compact camera systems where optical space, installation flexibility, and discreet imaging are important. Its 3.7mm focal length and 92° diagonal field of view allow the camera to capture a relatively broad area without requiring a large optical assembly.

The lens is particularly suitable for compact security cameras, access-control equipment, smart door monitoring devices, ATM and kiosk cameras, intercom systems, retail monitoring modules, and embedded IoT cameras. Its pinhole configuration can be integrated into devices where the camera needs to be positioned behind a small opening or within a compact enclosure, helping equipment designers maintain a clean external appearance.

For door access and indoor security systems, the 70° horizontal FOV provides useful coverage for monitoring people approaching an entrance, while the 0.1m minimum object distance makes the lens suitable for relatively close-range imaging. In smart devices and embedded monitoring equipment, the M12X0.5 interface simplifies mechanical integration for applications with limited available installation space.

The lens can also support selected compact industrial vision and embedded inspection applications where a small camera module must be installed close to the target. Manual focus allows integrators to adjust image sharpness during assembly according to the actual working distance.
