UN0551 Wide-Angle Lens, 1/2.8' Sensor, 2.41mm, F2.0 Aperture
Security Camera Lens
- 5MP Resolution for precise detail reproduction
- 160.1° Ultra-Wide Angle for a very wide area
UN0551 wide-angle lens features an F2.0 large aperture and a 1/2.8″ sensor, supporting 5 MP high resolution for bright, detailed, and accurate image reproduction. Its 160.1° diagonal ultra-wide field of view greatly expands monitoring coverage and minimizes blind spots. With 70% relative illumination (RI), it maintains excellent brightness uniformity from center to edge, while the –16.8% low-distortion design ensures realistic scene reproduction. Day-night co-focus technology keeps the image sharp and stable 24/7 without manual adjustment. Engineered for high-end security systems, the wide-angle lens meets the stringent requirements of surveillance equipment manufacturers for wide-angle coverage, high resolution, and superior low-light performance.
