Description
Introducing our high-performance 2.8mm F2.4 3MP M12 wide-angle pinhole lens, masterfully engineered for ultra-high-definition covert surveillance and discrete embedded imaging applications. Setting a new standard in hidden tracking, this premium pinhole board lens combines an expansive 115° diagonal field of view with a crisp 3 Megapixel resolution. Featuring an ultra-short 12mm Total Track Length (TTL) and a micro-head conical profile, it captures sweeping, razor-sharp 1536P footage through a single micro-aperture, making it the premier choice for premium smart kiosks, financial terminals, and blind-spot-free secure entryways.
Product Highlights
- 3MP Crystal-Clear Panoramic Vision: Upgrades your hidden network to 3 Megapixel Ultra HD, capturing 115 degrees of sweeping coverage while offering enough pixel density to zoom in on critical details.
- Low-Distortion 115° Wide Frame: The 2.8mm fixed focal length provides an optimized wide field of view that minimizes aggressive fisheye stretching, ensuring a natural, highly identifiable facial structure.
- Ultra-Flat 12mm Mechanical Build: The hyper-compressed 12mm TTL optical length makes this lens extremely flat, slipping effortlessly into zero-clearance housings and slim metallic panels.
- Tapered Needle-Nose Silhouette: Designed with a specialized micro-cone tip, allowing the entire physical enclosure to sit invisibly behind a tiny drill hole for absolute hidden surveillance.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 2.8mm 3MP pinhole lens is explicitly designed for high-resolution environmental logging, commercial terminal tracking, and high-security discrete entryways. Offering a wide 115-degree perspective, it excels as the primary optical sensor for smart parcel delivery lockers, banking automated teller machines (ATMs), and luxury automated retail kiosks where capturing the user’s upper body and immediate transaction space with 3MP clarity is non-negotiable. In advanced industrial settings and machine vision lens applications, its hyper-flat 12mm form factor allows it to be embedded inside compact electronic equipment rack doors or safety valves, monitoring automated operations through micro-holes while remaining safe from external mechanical friction or spray.
Compatible Device List
- Perfectly optimized for high-sensitivity 1/3-inch 3MP/2MP CMOS image sensors (including Sony, OmniVision, and SmartSens architectures).
- Seamlessly fits premium M12 hidden mini-camera modules, UHD network IPC boards, and Tuya-powered smart smart-home peep-hole units.
- Ideal for integration into custom industrial machine vision enclosures, luxury vending machine terminals, and covert tactical gear housings.
- Fully supports factory customization for dual-band pass filters (650nm / 850nm / 940nm) to facilitate true invisible infrared nighttime illumination.
“Designed for high-definition wide-angle covert surveillance and smart kiosk biometric tracking applications.”
Frequently Asked Questions
Q: How does this 2.8mm 3MP lens compare to your 2.5mm panoramic pinhole lens?
A: This 2.8mm lens upgrades the image clarity to an ultra-sharp 3 Megapixel (3MP) resolution and narrows the field of view slightly to 115° (compared to the 125° on the 2.5mm model). This slight change drastically improves pixel density, allowing you to zoom in and easily read text, clothing details, or small credentials in hidden security setups.

Q: Does the 115° wide perspective create a heavy fisheye bowing effect?
A: No. While it provides an expansive wide frame, the optical glass layout is highly calibrated to control distortion. It offers a much flatter, more natural perspective than typical ultra-wide fish-eyes, making it highly effective for facial recognition software.

Q: Why is the 12mm TTL important for embedded product designers?
A: The 12mm Total Track Length (TTL) confirms that the lens has a very low physical profile. It allows hardware engineers to design ultra-thin faceplates or position the camera module inside incredibly shallow gaps where standard 2MP board lenses would fail to fit.

Q: Is the focus on this 3MP 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 we order this pinhole lens with built-in 940nm IR-pass filtering?
A: Yes, we offer extensive OEM/ODM customization. We can factory-install specific IR filters (such as 850nm or 940nm) to match your invisible infrared night-vision setups for true undercover operations.
