Description
Introducing our high-performance 16mm F1.8 3MP M12 pinhole lens, masterfully engineered for ultra-high-definition covert surveillance and discrete embedded imaging networks. Featuring a micro-head conical profile and an ultra-compact 25.5mm Total Track Length (TTL), this premium pinhole board lens completely fills large 1/2″ image sensors without corner vignetting. Equipped with a bright F1.8 large aperture and a flat, distortion-free 22.5° horizontal field of view, it shoots crystal-clear 3MP imagery through microscopic physical openings, 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.
- Large 1/2″ Sensor Coverage: Unlike restrictive mini optics, this optical array is fully optimized for large 1/2-inch sensors, maximizing light collection and enhancing dynamic range.
- 16mm Precise Distortion-Free Focus: The 16mm fixed focal length and narrow 22.5° H.F.O.V. act like an invisible telephoto window, isolating and magnifying distant faces or credentials with zero wide-angle distortion.
- Ultra-Short 25.5mm 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 16mm F1.8 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 22.5-degree horizontal 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 3MP tracking in dim corridor or indoor environments.
Compatible Device List
- Tailored for high-sensitivity 1/2-inch, 1/2.7-inch, and 1/2.8-inch CMOS image sensors (such as Sony STARVIS IMX lines and OmniVision sensors).
- 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 F1.8 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 F1.8 aperture to deliver excellent nighttime video performance.

Q: Will this lens cause vignetting or dark corners on a 1/2-inch sensor?
A: Not at all. This lens is fully optimized for the large 1/2″ image format. It creates an expansive, high-resolution optical circle that covers the entire sensor plane, delivering crisp details from the absolute center to the very corners.

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.
