Description
Introducing our professional-grade 4mm F1.8 2MP CS-mount pinhole lens, masterfully engineered for advanced covert surveillance and industrial inspection through extra-thick walls or panels. Departing from standard miniature board optics, this heavy-duty long-barrel needle pinhole lens features a standard CS mount and a fully integrated DC Auto-Iris mechanism. Boasting an ultra-bright F1.8 large aperture and a standard 65° horizontal perspective, this fixed focal lens automatically adapts to extreme lighting shifts, making it the premier choice for professional box cameras deployed in outdoor security gates, thick banking vaults, and reactive industrial environments.
Product Highlights
-
- 100mm Long-Barrel Needle Architecture: Built with a specialized 100mm TTL elongated front tube, allowing the optical eye to drill and pass directly through thick security walls or double-pane enclosures for ultimate hidden surveillance.
- Intelligent DC Auto-Iris調光: Features built-in electromagnetic DC Auto Iris control, automatically optimizing contrast and protecting the sensor from blindness under harsh glare, fluctuating sunlight, or flashing strobes.
- Starlight-Level F1.8 Night Vision: The massive F1.8 aperture maximizes light throughput, significantly outperforming dark mini pinholes to ensure low-noise 2MP 1080P video under low-illumination night settings.
- Professional CS-Mount Stability: Eliminates the fragile threading of micro board lenses by pairing directly with high-end industrial CS-mount box cameras for a rigid, vibration-resistant setup.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 4mm CS-mount pinhole lens is explicitly built for extreme structural hideaways, high-risk environmental logging, and automated industrial lens sensing. Thanks to its unique 100mm long-barrel architecture, it functions as the definitive optical sensor for thick armored vehicle bodies, reinforced banking safe vaults, and outdoor security gate walls where a micro M12 lens would be buried and blocked. Offering an intelligent DC Auto-Iris and an ultra-short 0.15m M.O.D., it excels inside high-temperature industrial smelting furnaces or pressurized manufacturing machinery cabins. The lens tube can pierce through thick thermal insulating jackets to monitor close-up automated assemblies or scan micro-labels at point-blank range, continuously adapting its F1.8 shutter circle to combat fierce inner sparks or flashing hazard lights.
Compatible Device List
-
- Fully compatible with standard 1/3-inch and 1/4-inch CMOS box cameras with standard CS-mount interfaces (such as Sony STARVIS or Panasonic professional IPC engines).
- Directly plugs into mainstream security DVR/IPC modules supporting 4-pin DC Auto-Iris control drive cables.
- Ideal for integration into custom machine vision lens enclosures, tactical police armor panels, and heavy-duty automated banking kiosks.
- Fully supports factory customization for dual-band pass coatings (650nm IR cut / 850nm / 940nm IR pass) to facilitate true invisible infrared nighttime illumination.
“Designed for wall-penetrating covert surveillance and professional auto-iris industrial inspection applications.”
Frequently Asked Questions
Q: Why does this pinhole lens have a 100mm TTL and a CS mount instead of an M12 micro shape?
A: This is a professional long-barrel stick pinhole lens. It is designed for applications where the camera body cannot be near the front panel. The 100mm TTL lets the camera hide deep inside walls or thick metal machinery housings, extending a thin front needle out to the micro-aperture. The CS mount allows it to connect seamlessly with full-sized, industrial-grade box cameras.

Q: What is the technical advantage of the DC Auto Iris in a hidden camera setup?
A: Standard pinhole lenses have a fixed aperture, which means they easily overexpose in bright sunlight or blur in darkness. This DC auto‑iris uses a standard 4‑pin cable to connect to your camera board, auto‑adjusting its F1.8 iris for low‑noise, well‑exposed outdoor imagery.

Q: Can this long 100mm lens be used for close-up macro scanning?
A: Yes. Despite its long physical barrel, it features an exceptionally short M.O.D. of 0.15 meters (15cm). This allows the needle tip to be positioned very close to high-speed conveyor belts or robotic arms to monitor delicate close-up components without wide-angle fisheye distortion.

Q: How do I adjust the manual focus on this elongated pinhole lens?
A: The focus ring is located on the rear section of the 100mm barrel, near the CS mount base. Screw the lens onto your box camera, connect the iris cable, adjust the manual‑focus ring for sharp live‑view imagery and lock with the built‑in thumb screw.

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.
