Description
Enhance your surveillance capabilities with our premium 2MP 2.8-12mm varifocal CS-mount CCTV lens. Engineered for 1/3″ image sensors, this high-definition security lens offers a versatile focal range and a wide 98° to 29° field of view, making it the ultimate choice for dynamic security environments. With integrated IR correction and a fast F1.4 aperture, it eliminates focus shift under infrared illumination, delivering crisp, distortion-free 1080P imagery 24/7.
Key Product Highlights
-
- Versatile 2.8-12mm Varifocal Range: Transition smoothly from a 98° wide-angle overview to a 29° telephoto detail, eliminating monitoring blind spots with manual zoom and focus.
- Stunning 2MP Low-Light Clarity: The ultra-bright F1.4 aperture captures more light, producing crystal-clear 2 Megapixel resolution even in challenging, low-light environments.
- Seamless IR-Corrected Day/Night Transition: Advanced IR corrected lens technology prevents focus shift under infrared light, ensuring sharp focus from day to night.
- Precise DC Auto Iris Control: Automatically adjusts to shifting outdoor light conditions, protecting your sensor from overexposure while maintaining optimal image contrast.

Applications & Compatible Equipment
This varifocal day&night lens is specifically optimized for high-definition security and traffic monitoring environments. It excels in mainstream commercial security applications, such as retail store entrances, bank lobbies, parking lot gates, and public intersections where lighting conditions vary dramatically throughout the day. The 2.8-12mm manual zoom allows installers to fine-tune the field of view on-site, making it highly valuable for perimeter intrusion detection and license plate capturing at short-to-medium distances.
Compatible Equipment List:
-
- Sensors: Fully compatible with 1/3″ and 1/4″ industry-standard CMOS/CCD sensors.
- Security Cameras: Fits all standard CS-mount box cameras, IP cameras, and analog HD surveillance housings.
- Brands: Perfect fit for Hikvision, Dahua, Axis, and Bosch box camera modules.
- Industrial Systems: Adaptable to standard industrial vision enclosures requiring a manual zoom lens with auto-iris capabilities.
“Designed for versatile day & night security surveillance applications.”
Frequently Asked Questions
-
- Q: Does this lens support automatic focus and zoom adjustment?
-
- A: No, this lens features manual focus and manual zoom. You adjust the focal length (2.8-12mm) and clarity manually during installation to fit your specific scene.
-
- Q: What does “IR Corrected” mean for this lens?
-
- A: IR corrected lens technology uses specialized optical glass to ensure that both visible light and infrared light focus on the exact same plane. This prevents the image from going out of focus when night-vision IR illuminators turn on.
-
- Q: Will this lens fit a C-mount camera?
-
- A: This is a native CS-mount lens. To use it on a C-mount camera, you would need a standard 5mm C-to-CS mount adapter ring, though it is highly recommended to use it directly with CS-mount cameras.
-
- Q: What is a DC Auto Iris and why do I need it?
-
- A: A DC Auto Iris automatically adjusts the lens aperture based on the level of sunlight. It is essential for outdoor or window-facing cameras to prevent video washout during bright days and ensure enough light enters at night.
-
- Q: Can I use this lens with a 5 Megapixel camera sensor?
-
- A: This lens is optically optimized for 2 Megapixel (1080P) resolutions. While it will physically mount to a 5MP camera, the output resolution will be optically limited to 2MP quality.
-
- Q: What is the Minimum Object Distance (M.O.D.) for this lens?
-
- A: The M.O.D. is 0.3 meters (approx. 1 foot). The lens can clearly focus on objects as close as 30cm away from the front glass element.
