Product Description
Haoyuan 1/2.7 sensor with 14 heads and a focal length of 3.2 millimeters provides a wide field of view, allowing for capturing more of the surrounding environment. The 2.4mm aperture ensures excellent transparency, allowing for bright and vivid visual effects even in low light conditions. Paired with four pieces of glass IR650 in the dash cam, it effectively filters out infrared light, enhances image clarity, and reduces glare. This feature is particularly useful for recording during the day or in areas with bright light, as it helps prevent overexposure and ensure balanced exposure levels. It takes into account precision and performance, using a durable metal casing to ensure protection and service life. Its sturdy structure makes it suitable for various environments, with operating temperatures ranging from -30 to+85 º C, making it an ideal choice for outdoor and industrial applications. The maximum imaging size covers 1/2.8 ", 1/3.7", 1/3 ", 1/4"
