Description
Eliminate visual blind spots and elevate your security matrix with our professional-grade 3MP 2.1mm CS-Mount Automotive Lens. Specially tailored to match widely used 1/3″ image sensors, this ultra Wide Angle Lens captures an immersive 153° diagonal field of view, making it an excellent standalone solution for complete room or wide-area coverage. Engineered with an ultra-bright F1.6 aperture and specialized IR Corrected optical coatings, it excels in extreme low-light environments and ensures seamlessly sharp images across both visible and infrared spectrums. As a highly reliable Fixed Focal Lens, its robust mechanical design and manual focus precision offer a cost-effective, high-efficiency upgrade for large-scale CCTV Lens networks, rugged Industrial Lens setups, and peripheral vehicle monitoring configurations.
Key Highlights & Advantages
- 153° Panoramic Field of View: The ultra-short 2.1mm focal length provides a broad 153° diagonal and 125° horizontal coverage, allowing a single camera setup to monitor expansive areas and replace multiple standard lenses.
- Ultra-Bright F1.6 Aperture for Low Light: Maximizes light intake on 1/3″ sensors, significantly reducing image noise in low-illumination setups and ensuring clear visibility during twilight or dimly lit industrial shifts.
- Day/Night IR Corrected Technology: Advanced multi-coating eliminates focus shift when switching between daytime visible light and nighttime infrared (IR) illumination, providing crisp 3MP resolution 24/7.
- Dependable CS-Mount Architecture: Offers a standard, stable CS mechanical interface combined with a lockable manual focus system, designed to withstand continuous operation without shifting focus over time.

Applications & Compatible Equipment
Core Application Scenarios
This wide-angle Fixed Focal Lens is purpose-built for comprehensive environmental tracking and situational awareness where multi-camera budgets are limited. It serves as an essential CCTV Lens for wide-area monitoring inside retail stores, bank lobbies, elevators, and warehouse aisles where spotting movement across a whole floor is vital. Its panoramic nature also functions excellently in logistics centers as an Industrial Lens to monitor wide conveyor belt feeds, packaging sorting docks, and indoor robotic vehicle paths. Furthermore, due to its resilient build, it acts reliably as an Automotive Lens asset for wide-angle rear-view integration, large commercial truck blind-spot detection, and transit cabin surveillance.
Compatible Equipment List
- Sensors & Formats: Fully optimized for standard 1/3″, 1/4″, and 1/2.7″ CMOS/CCD image sensors (including mainstream security sensor modules).
- Security & Box Cameras: Fits natively into CS-mount analog and IP network box cameras from major industry brands like Hikvision, Dahua, Uniview, and Bosch.
- Enclosures & Integration Modules: Easily integrates into indoor dome housings, transit vehicle camera boxes, toll station enforcement structures, and compact automated machinery.
- Customization Services: Supports specific modifications for high-vibration resistance locking rings, customized shell designs, or tailored optical IR bandpass coatings.

Frequently Asked Questions
Q: Will this 2.1mm lens cause severe barrel distortion on the edges?
A: Yes, as an ultra-wide Lens, it will introduce a curved, circular perspective on the borders. This distortion is standard for a 2.1mm focal length and is optimized to capture a massive 153° viewing field. For standard viewing, it can be easily straightened out via camera-side software dewarping algorithms.

Q: Can this CS-mount lens fit onto an M12 miniature camera board?
A: No, this is a native CS-mount lens. Its physical thread size and back focal length require a standard CS camera body. It cannot fit directly onto an M12 board camera unless you utilize a specialized mechanical adapter housing.

Q: What is the real-world advantage of the F1.6 aperture on this lens?
A: An F1.6 aperture is exceptionally bright. It allows far more light to strike the 1/3″ sensor compared to common F2.0 or F2.4 lenses. This allows the camera to produce brighter color images in low-light environments before needing to trigger infrared night mode.

Q: Does this lens require focus adjustments when switching from day to night?
A: No. Because it is an IR Corrected Lens, it utilizes specialized optical glass that focuses both visible light wavelengths and near-infrared wavelengths onto the exact same sensor plane. This keeps your 3MP feed razor-sharp 24/7.

Q: Is the iris adjustable for locations with changing sunlight?
A: No, this lens features a Fixed Iris. Exposure control must be managed by your camera’s automatic electronic shutter speed or automatic digital gain (AGC) settings, which is standard for wide-angle security deployments.

Q: Can I use this 1/3″ format lens on a larger 1/1.8″ sensor?
A: No, using a 1/3″ lens on a larger 1/1.8″ sensor will result in heavy black circular corners (vignetting), because the lens’s optical light circle is too small to cover the larger sensor surface. Always match it with a 1/3″ or smaller sensor size.
