CCTV lenses, also known as surveillance cameras or security cameras, are an important security monitoring equipment and are mainly used for security monitoring and image recording in various places. Here are some special features of CCTV footage:Multiple ways to shoot: CCTV footage can be shot in a variety of ways. For example, the lens can be fixed in a certain position for fixed-point shooting, or it can rotate in all directions, or even perform continuous shooting from multiple angles. These functions can be realized through corresponding control systems.Remote control: CCTV lenses are usually equipped with corresponding remote control systems. Users can remotely control the lens through remote control, computer or mobile phone and other devices, including adjusting the angle, focal length, brightness and other parameters of the lens, and can also view the shooting in real time. image or video.Image processing and recognition: Modern CCTV cameras are usually equipped with high-resolution image sensors and image processing chips that can process and recognize the captured images. For example, the lens can detect important information such as faces, body movements, license plate numbers, etc., and automatically identify and classify them. These features can help users better understand the conditions and anomalies in the monitored area.Motion detection and alarm: CCTV cameras can detect moving objects and automatically alarm. The system will automatically identify moving objects or people and immediately send out an alarm signal, while also sending images or videos to the designated mailbox or police department.Multiplatform compatibility: Modern CCTV lenses are compatible with multiple platforms, such as PCs, mobile phones, tablets and other devices. Users can watch in real time or record video playback in a variety of ways.To sum up, CCTV lenses have a variety of special functions that can help users better understand the conditions and abnormalities in the monitored area and improve safety and work efficiency.

AVM is a panoramic image system, namely Automotive Around View Monitor/Surround View Camera.It is another great helper for safe driving and can realize driving without blind spots.Images are captured through multiple ultra-large wide-angle fisheye lenses, and then the captured images are distorted and spliced through data processing to form surrounding images.It is mostly used in automobile systems to provide the driver with a bird's-eye view of the surroundings of the car body, eliminate the driver's blind spots, and provide effective visual assistance when parking.In fact, surround view systems can be divided into monocular, binocular and multi-view systems.Among them, the monocular and binocular systems must establish a virtual coordinate system while the vehicle is moving to draw a panoramic image to guide parking. The multi-view system can directly guide parking.⁉ So how many cameras are needed for the entire operation process?✔ 360-degree panoramic camera, 360-degree panoramic imaging system, 360-degree panoramic parking system, 360-degree panoramic vision system, and 360-degree panoramic reversing system simultaneously collect images around the vehicle through 4 ultra-wide-angle cameras installed on the front, rear, left, and right of the vehicle.✔ Through Pujieli's proprietary "real-time image distortion restoration docking technology", the image is processed through distortion restoration, perspective conversion, image splicing, and image enhancement, and finally forms a seamless and complete panoramic bird's-eye view of the car's surroundings.✔ The system can not only display a panoramic view, but also display a single view in any direction at the same time; the driver can accurately read the location and distance of obstacles by matching the ruler lines.  

The technical principles of car mounted surround lenses mainly include the following aspects:Lens design: Car surround photography typically uses multiple cameras, which are distributed around the vehicle to provide a more comprehensive view. The design of a lens needs to consider various factors, such as the focal length, aperture, angle of view, etc., in order to obtain high-quality images during the shooting process.Shooting method: The shooting method for car surround lenses includes two aspects: hardware and software. Hardware includes cameras, brackets, power supplies, etc. It is necessary to choose high-quality equipment to ensure the stability of shooting. In terms of software, post production requires professional image processing software to fuse and concatenate images captured by multiple cameras to form the final surround lens image.Post processing: After the shooting is completed, it is necessary to perform post processing on images from multiple cameras in order to fuse them into a complete image.
