Fisheye panoramic surveillance camera refers to a surveillance camera that uses a special wide-angle lens(commonly known as a fisheye lens) to achieve the largest range of viewing angles. The focal length of this surveillance camera is generally 1.7mm or shorter and the viewing angle can be close to 180°(horizontal direction) coverage, one unit can achieve large-area monitoring coverage without blind spots. The panoramic camera is mainly composed of multiple wide-angle lenses with different orientations at the same time to collect the surrounding images. After the image processing unit is corrected and spliced, a complete 360-degree image is formed the panoramic picture is transmitted to the recording host in real time and finally displayed.
