Description

Technical Field

[0001] This utility model relates to the technical field of cameras, specifically a wide-angle surveillance camera. Background Technology

[0002] Video surveillance systems have been widely used in our workplaces and living spaces. Depending on the specific needs, the requirements for the images captured by surveillance videos are becoming increasingly detailed. The essential function of video surveillance is usually reflected in post-event playback and retrieval. The range and clarity of the video recording reflect the practical value of a video surveillance system. Ordinary surveillance cameras with excessively wide imaging angles will suffer from insufficient clarity. To ensure image clarity, the viewing angle is generally limited to no more than 70 degrees. Installing such ordinary-angle surveillance cameras in limited spaces inevitably leads to blind spots, resulting in unfortunate blind spots during video playback. A surveillance camera technology that can provide wide-angle, high-pixel imaging is a highly practical market demand. Utility Model Content
