Description
Introducing our high-performance 22mm F1.6 2MP M12 telephoto pinhole lens, masterfully engineered for high-definition covert surveillance and discrete embedded imaging applications. Featuring an ultra-compact 30mm Total Track Length (TTL) and a micro-head conical profile, this premium pinhole board lens completely fills large 1/2″ image sensors without corner vignetting. Equipped with an ultra-bright F1.6 large aperture that completely shatters the low-light limitations of traditional dark pinhole designs, it ensures crystal-clear, low-noise 1080P video capture, 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 Optimization: Engineered to cover large 1/2-inch image sensors, maximizing light collection, enhancing dynamic range, and delivering exceptional edge-to-edge clarity.
- Revolutionary F1.6 Low-Light Iris: Breaks the industry limitation of dark pinhole optics by maximizing light throughput, rendering bright 2MP images without relying on aggressive digital amplification.
- 22mm Precise Telephoto Focus: The 22mm fixed focal length and narrow 15° H.F.O.V. act like an invisible telephoto window, isolating and magnifying distant faces or credentials with zero wide-angle distortion.

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 long-distance visual verification. It functions as the core optical module for ATM hidden security cameras, remote banking kiosks, and high-security access control gates where the camera hardware must remain completely invisible to the public while capturing targets at a distance. Thanks to its narrow 15-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 flexible distance inside compact enclosures. The micro-conical front element effortlessly slips into pre-drilled panel gaps, minimizing installation footprints while providing uncompromised 2MP 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: How does a 22mm lens with a 1/2″ sensor format function as a pinhole lens?
A: Unlike standard wide-angle pinholes that only support small sensors, this model is a premium large-format telephoto pinhole lens. It is engineered with a narrow, micro-tapered cone tip that can hide behind a tiny physical slot, while its specialized internal glass layout covers a large 1/2″ sensor and provides a zoomed-in perspective.

Q: Will this 22mm lens cause vignetting or dark corners on a 1/2-inch sensor?
A: Not at all. This lens is fully optimized for the 1/2″ image format. It creates a large, high-resolution optical circle that covers the entire sensor plane, delivering crisp details and uniform brightness from the 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.
