Description
Introducing our ultra-compact 3.7mm F2.5 M12 Micro Pinhole CCTV Lens, purpose-built for zero-clearance hardware embedding and close-up covert surveillance applications. Shuttering industry limitations, this premium short-TTL pinhole board lens features a record-breaking 10.5mm Total Track Length (TTL), making it significantly shorter than standard 3.7mm optics. Delivering an optimized 70° horizontal field of view and an enhanced 0.2m minimum object distance (M.O.D.), it captures sharp, low-distortion megapixel video at close range through microscopic panel gaps, making it the premier choice for ultra-thin smart doorbells, handheld law enforcement tech, and micro-payment kiosks.
Product Highlights
- Record-Breaking 10.5mm Short TTL: The most compressed axial profile in its class, resolving extreme mechanical spacing conflicts inside ultra-slim product chassis and thin metallic faceplates.
- 0.2m Advanced Micro-Focusing: Features an upgraded M.O.D. of 0.2 meters, allowing the hidden camera to capture razor-sharp biometric details and barcodes at much closer distances than standard pinholes.
- Low-Distortion 70° Portrait Frame: The calibrated 70° horizontal F.O.V. drastically suppresses aggressive corner bending, providing linear, undistorted images optimized for local facial recognition software.
- Micro-Cone Needle Silhouette: Built with a highly tapered conical front tip, ensuring the heavy optical body remains entirely hidden behind the panel plane for flawless hidden surveillance.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 3.7mm ultra-short pinhole lens is explicitly engineered for ultra-thin interface security, mobile tactical body-worn tech, and close-up industrial lens data tracking. Offering a highly natural 70-degree horizontal perspective with a rare 0.2m macro-focus range, it excels as the primary optical sensor for ultra-slim home smart video doorbells, lightweight handheld law enforcement recorders, and compact tabletop point-of-sale (POS) systems where space behind the outer shell is restricted to millimeters. In advanced factory automation and machine vision lens setups, its flat 10.5mm profile allows it to be embedded flush inside tiny mechanical gripper knuckles, low-profile conveyor sideboards, or sorting chutes, monitoring delicate close-up sorting processes through micro-holes without interfering with mechanical clearance paths.
Compatible Device List
- Perfectly optimized for high-sensitivity 1/3-inch CMOS image sensors (including Sony, OmniVision, and SmartSens series).
- Direct fit for ultra-short M12 hidden camera modules, micro pocket-sized IPC boards, and Tuya-powered ultra-thin smart doorbells.
- Ideal for integration into custom industrial machine vision enclosures, mini biometric gate control keypads, and wearable button-cam 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 ultra-short enclosure terminal security and close-range micro pinhole surveillance applications.”
Frequently Asked Questions
Q: What makes this 3.7mm pinhole lens different from your standard 3.7mm pinhole lenses?
A: This model is specifically engineered for severe space constraints. It compresses the Total Track Length (TTL) down to a record 10.5mm (compared to standard 11mm or 13mm models) and shortens the minimum object distance (M.O.D.) to 0.2 meters, allowing it to fit into thinner device shells and focus perfectly on targets that are much closer to the hidden aperture.

Q: Does this ultra-short optical layout compromise image distortion control?
A: Not at all. Despite its hyper-compressed 10.5mm physical thickness, the multi-element glass array maintains an exact 70° horizontal view with exceptional distortion control. Straight structural lines and facial profiles remain linear and natural, making it highly reliable for edge-AI processing.

Q: Why is the 10.5mm TTL critical for hardware product developers?
A: In modern smart doorbells and mobile body cameras, every millimeter of depth matters. A 10.5mm TTL ensures that your engineering team can drastically reduce the thickness of the overall device housing, keeping the camera sensor module entirely flush with the cover plate.

Q: Is the focus on this micro 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 starting from just 0.2 meters away up to infinity, then lock it securely using an M12 retaining collar.
