HW - PFL - VG2812 - 4MP CCTV Lens

• Focal Length: Its variable focal length spans from 2.8mm to 12mm, offering remarkable versatility. It enables users to capture expansive wide - angle views for comprehensive area monitoring or zoom in with telephoto views for detailed scrutiny of specific subjects.
• Resolution: Featuring a 4 - MegaPixel resolution, it delivers sharp and detailed imagery. This high - resolution capability ensures that objects and people can be clearly identified, even in intricate surveillance scenarios.
• Aperture: Sporting an F1.8±10% aperture, the lens excels in light collection. This is of great significance in low - light environments, as it helps reduce image noise and elevate the overall quality of captured footage.
• Field of View: Depending on the sensor size (1/2.7″, 1/3″, 1/4″) and focal length adjustments, it offers a broad spectrum of field angles. For instance, with a 1/2.7″ sensor at the short - focal end, the diagonal field angle can reach an impressive 153.8°, providing extensive coverage.
• Optical Distortion: Optical distortion is maintained within the range of - 76.4% ~ - 3.85% (for 1/2.7″ sensor), effectively minimizing image distortion and guaranteeing an accurate depiction of the monitored environment. The chief ray angle (CRA) is also precisely specified, with ≤8° at the short - focal end and ≤9.43° at the long - focal end, which contributes to uniform image quality across the sensor.

• Mount: Fitted with a CS mount, it is highly compatible with a wide array of CCTV cameras. This makes installation and integration into existing surveillance systems a breeze.
• IR Correction: The lens is equipped with night - day IR correction functionality. This ensures that the focus remains stable when transitioning between visible light and infrared light, a crucial feature for round - the - clock surveillance.
• Iris, Focus and Zoom: It incorporates an automatic (DC) iris that adapts to different lighting conditions. Additionally, the focus and zoom functions are manually adjustable. This combination empowers users to precisely customize the image based on specific surveillance needs.
• Dimensions and Weight: With a compact footprint of Φ34×44.65mm and weighing 62±2g, it is convenient to install in diverse locations without occupying excessive space.
• Operating Temperature: It can operate reliably within a temperature range of - 20°C to +70°C. This wide temperature tolerance makes it suitable for a variety of environmental conditions, whether it's the frigid outdoors in winter or warm indoor settings.
