Not too wide, not too narrow—it offers the perfect balance for monitoring stores, offices, entrances, and more. In this guide, we break down how it works, where it shines, its few quirks (like distortion), and why it’s a go-to choice for real-world surveillance—no engineering degree required.


Motion DV lenses are camera accessory devices specifically designed for motion scenes. They usually have features such as anti-shake, wide-angle, and high pixel count, and are suitable for recording during outdoor activities like cycling, skiing, and fishing.

Panoramic endoscopic imaging is currently primarily applied in capsule endoscopes and large-field-of-view colorectaloscopes. The development of capsule endoscopes is highly diverse, with practical applications ranging from ordinary ultra-wide-angle lenses to the stitching of images from multiple cameras. The large field of view in colonoscopes is mainly achieved through multi-camera image stitching and multi-perspective display. The following section discusses the application of panoramic endoscopic imaging technology in these two types of endoscopes, considering the related diseases requiring diagnosis and treatment.
