Description
Introducing our high-performance 2.8mm F2.4 3MP M12 wide-angle pinhole CCTV lens, masterfully engineered for large-format 1/2.7″ image sensors in high-definition covert surveillance and smart embedded imaging networks. Standing out in the premium hidden optics segment, this unique pinhole board lens breaks standard limitations by projecting an expansive 108° horizontal / 140° diagonal field of view onto larger sensor architectures with pristine 3 Megapixel resolution. Featuring an ultra-short 12mm Total Track Length (TTL) and a micro-head conical profile, it captures sweeping, razor-sharp 1536P video through a single micro-aperture, making it the premier choice for professional banking terminals, elevator safety, and blind-spot-free secure entryways.
Product Highlights
- 1/2.7″ Large Sensor Panoramic Optimization: Custom-calibrated for high-sensitivity, larger-format 1/2.7-inch CMOS chips, maximizing light collection and preventing corner vignetting or edge blurring common in standard mini optics.
- 3MP Crystal-Clear Edge Resolution: Upgrades your hidden security architecture to 3 Megapixel Ultra HD, providing excellent relative illumination and uniform brightness across the entire 140° diagonal frame.
- Ultra-Flat 12mm Mechanical Build: The hyper-compressed 12mm TTL optical length resolves strict clearance challenges in low-profile electronic housing, sitting completely flush inside slim enclosures.
- Tapered Needle-Nose Silhouette: Designed with a specialized micro-cone tip, allowing the entire physical optical block to remain perfectly invisible behind a tiny pre-drilled panel hole for absolute hidden surveillance.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 2.8mm 3MP large-format pinhole CCTV lens is explicitly tailored for high-resolution environmental logging, commercial terminal tracking, and high-security discrete entryways. Offering an expansive 108-degree horizontal perspective, it excels as the primary optical sensor for luxury banking automated teller machines (ATMs), elevator hidden security cameras, and secure self-service ticketing kiosks where capturing both the user’s facial details and the immediate wide surroundings under fluctuating indoor lighting is non-negotiable. In modern manufacturing and machine vision lens setups, its hyper-flat 12mm form factor and short 0.2m M.O.D. allow it to be embedded inside compact sorting machines or high-traffic robotic enclosures, monitoring automated operations through micro-holes while pairing seamlessly with wide-dynamic-range (WDR) sensors to handle harsh metallic reflections.
Compatible Device List
- Perfectly optimized for high-sensitivity 1/2.7-inch and 1/2.8-inch CMOS image sensors (such as Sony STARVIS IMX lines, OmniVision, and SmartSens architectures).
- Seamlessly fits premium M12 hidden mini-camera modules, wide-dynamic UHD network IPC boards, and high-end video intercom systems.
- Ideal for integration into custom Industrial lens enclosures, smart parcel lockers, and automated retail kiosk housings.
- Fully supports factory customization for dual-band pass filters (650nm IR cut / 850nm / 940nm IR pass) to facilitate true invisible infrared nighttime illumination.
“Designed for high-definition 1/2.7″ format wide-angle covert surveillance and terminal biometric tracking applications.”
Frequently Asked Questions
Q: What makes this 2.8mm pinhole lens unique compared to standard 2.8mm 1/3″ pinhole lenses?
A: Standard 2.8mm pinholes are designed for smaller 1/3″ or 1/4″ sensors. If you put them on a larger 1/2.7″ sensor, the corners will appear dark (vignetting). This lens features a customized large optical circle optimized specifically for 1/2.7″ image format sensors, extending the horizontal field of view to an ultra-wide 108° with crystal-clear 3MP resolution from center to edge.

Q: Does the ultra-wide 140° diagonal frame create a heavy fisheye bending effect?
A: While it provides a sweeping panoramic frame, the optical glass layout is highly calibrated to control image bending. It delivers a much flatter and more natural perspective than typical wide-angle board lenses, making it highly effective for AI-driven facial recognition software.

Q: Why is the 12mm TTL critical for embedded kiosk and ATM engineering?
A: The 12mm Total Track Length (TTL) confirms that the lens has an incredibly low physical profile. This allows your hardware engineering team to design ultra-thin faceplates or position the camera sensor module inside exceptionally shallow cavities where standard wide-angle board lenses would physically stick out.

Q: Is the focus on this 3MP M12 wide-angle 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 starting from just 0.2 meters away up to infinity, then lock it securely using a standard M12 retaining collar.
