Description
Introducing our ultra-compact 2.5mm F2.5 M12 wide-angle pinhole lens, masterfully engineered for comprehensive covert surveillance and panoramic embedded imaging networks. Setting itself apart with an incredible 125° diagonal field of view and an ultra-short 11.5mm Total Track Length (TTL), this pinhole board lens completely redefines mini-surveillance by capturing entire rooms through a single micro-aperture. With its standard M12x0.5 mount and optimized megapixel optics, it is the ultimate solution for blind-spot elimination in smart vending machines, secure payment kiosks, and discrete residential security entryways.
Product Highlights
-
- Panoramic Blind-Spot Elimination: Boasts a massive 125° Diagonal / 88° Horizontal F.O.V., allowing the camera to monitor an entire wide area through a tiny drill hole without needing to pan or tilt.
- Ultra-Flat 11.5mm Micro Footprint: The hyper-compressed 11.5mm TTL optical length makes this lens one of the flattest pinholes on the market, perfectly fitting into zero-clearance smart devices and ultra-thin panels.
- Micro-Head Conical Housing: Features a specialized tapered needle-nose front end, ensuring the entire physical housing remains entirely hidden behind the surface plane for true hidden surveillance.
- Instant Corner-to-Corner Focus: Engineered with a strict minimum object distance (M.O.D. of 0.2m), delivering crisp megapixel clarity from immediate close-up objects out to a wide background.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 2.5mm wide-angle pinhole lens is specifically tailored for wide-area ambient logging, indoor space tracking, and discrete smart terminal entryways. Unlike long-focal telephoto pinholes that isolate specific far-off objects, this 125-degree lens is built for full-room awareness, making it the perfect choice for elevator hidden security cameras, residential smart video doorbells, and automatic teller machines (ATMs) where capturing both the user’s upper body and the immediate surroundings is crucial. In automated factory environments and machine vision lens setups, its flat 11.5mm form factor allows it to be embedded inside compact electrical panels or high-traffic robotic junction boxes to monitor overall system safety and manual access without intruding into operational clearances.
Compatible Device List
-
- Perfectly optimized for standard 1/3-inch CMOS image sensors (including Sony, OmniVision, and SmartSens series).
- Direct fit for M12 hidden mini-camera modules, wide-angle IPC boards, and Tuya-powered smart smart-home peep-hole units.
- Ideal for integration into custom industrial machine vision enclosures, smart safety lockers, and automated retail kiosk housings.
- Fully supports factory customization for dual-band pass filters (650nm / 850nm / 940nm) to facilitate true invisible infrared nighttime illumination.
“Designed for wide-angle panoramic covert surveillance and embedded kiosk safety applications.”
Frequently Asked Questions
Q: How does this 2.5mm lens differ from your other 15mm or 30mm pinhole lenses?
A: This is a panoramic wide-angle pinhole lens. While our 15mm, 22mm, and 30mm lenses act like mini telescopes to capture far-off objects with a tight view, this 2.5mm lens does the opposite—it captures a very wide 125° field of view, making it ideal for monitoring large, enclosed rooms or immediate close-up surroundings.

Q: Does the 125° wide field of view cause any dark corners (vignetting)?
A: No. This lens is fully optimized for the 1/3″ image format. It creates a precisely calibrated optical circle that fully covers the sensor area, providing uniform brightness and sharp resolution from the absolute center to the very edge of the frame.

Q: Why does this lens have a 11.5mm TTL and how does it help my enclosure design?
A: The 11.5mm Total Track Length (TTL) means the lens is exceptionally short and flat. This allows your engineering team to design ultra-thin faceplates or embed the camera module inside shallow spaces where standard board lenses would physically stick out.

Q: Is the focus on this wide-angle 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.
