Description
Introducing our high-performance 22mm F1.6 M12 pinhole lens, masterfully engineered for megapixel covert surveillance and discrete embedded imaging applications. Featuring a micro-head conical profile and an ultra-compact 30mm Total Track Length (TTL), this premium pinhole board lens is designed to shoot high-contrast imagery through microscopic physical openings. Equipped with an ultra-bright F1.6 large aperture that completely eliminates the dark, grainy defects of traditional pinholes, it ensures crisp, low-noise video capture in dim environments, making it the premier choice for secure automated kiosks, ATM identification, and hidden security networks.
Product Highlights
- Micro-Cone Pinhole Architecture: The specialized tapered front barrel allows the lens to hide completely behind panel surfaces, looking out through a tiny drill hole for absolute hidden surveillance.
- Revolutionary F1.6 Low-Light Iris: Breaks the industry limitation of dark pinhole optics by maximizing light throughput, rendering bright megapixel images without relying on aggressive digital amplification.
- 22mm Precise Telephoto Focus: The 22mm fixed focal length and narrow 13° H.F.O.V. act like an invisible telephoto window, isolating and magnifying distant faces, tokens, or credentials with zero wide-angle distortion.
- Ultra-Short 30mm Space-Saving Profile: The highly compressed optical length fits seamlessly into ultra-thin ATM chassis, luxury automated vending machines, and compact smart IoT enclosures.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 22mm F1.6 pinhole lens is custom-designed for critical privacy protection, anti-vandalism, and undercover visual verification. It functions as the core optical module for ATM hidden security cameras, smart banking kiosks, and high-security access control gates where the camera hardware must remain completely invisible to the public. Thanks to its narrow 13-degree field of view and short 0.2m M.O.D., it excels at capturing detailed biometric data, close-up currency validation, and passport scanning from a fixed distance inside compact enclosures. The micro-conical front element effortlessly slips into pre-drilled panel gaps, minimizing installation footprints while providing uncompromised tracking in dim corridor or indoor environments.
Compatible Device List
- Tailored for high-sensitivity 1/3-inch CMOS image sensors (such as Sony STARVIS, OmniVision, and SmartSens series).
- Fits standard M12 hidden mini-camera modules, covert IPC boards, and Tuya-powered smart smart-home peep-hole units.
- Ideal for embedding into custom industrial machine vision enclosures, smart safety lockers, and tactical undercover gear.
- Supports customizable day/night dual-band coatings (650nm IR cut / 850nm / 940nm IR pass) to facilitate true invisible infrared nighttime illumination.
“Designed for covert surveillance and discrete embedded biometric tracking applications.”
Frequently Asked Questions
Q: Why does this pinhole lens have a large F1.6 aperture instead of a tiny pinhole dot?
A: This is a modern refractive optical pinhole lens. It utilizes a tapered, cone-shaped front barrel that lets it hide behind a microscopic external opening, while the specialized internal glass layout maintains a bright F1.6 aperture to deliver excellent nighttime video performance.

Q: Does the 22mm focal length cause a fisheye distortion effect?
A: No, quite the opposite. A 22mm lens on a 1/3″ sensor provides a narrow, zoomed-in 13-degree field of view. It acts like a mini-telephoto lens, offering a flat, distortion-free image that is perfect for capturing specific targets at a distance.

Q: Is the focus on this M12 pinhole lens adjustable?
A: Yes. It features a manual focus mechanism. By rotating the lens within its thread on the M12 mount board, you can adjust the focus for targets ranging from 0.2 meters away to infinity, then lock it securely using an M12 retaining collar.

Q: Can this lens withstand tight, unventilated spaces inside an ATM or kiosk?
A: Absolutely. Built to strict industrial standards, our M12 board lenses are constructed with temperature-stable housings and high-precision glass elements, ensuring consistent focal stability and zero thermal drift in enclosed spaces.
