Product Introduction
CM8452EM
Four-group coordinated design with stepper motor drive; features high focusing speed and precise focus tracking, meeting requirements such as UAV tracking.
Multi-piece aspherical optical glass delivers 10% superior clarity compared with comparable products.
Powered by a high-performance AI main control chip, the camera incorporates deep learning-based recognition and alarm algorithms for people, vehicles, smoke, fire, and other targets, enabling diversified and deeply integrated intelligent security protection. It is widely deployed in perimeter security, fire prevention and disaster mitigation, and related projects.
Leveraging the real-time performance and high-bandwidth efficiency of the MIPI interface, lossless video image data at 4 MP @ 60 fps can be transmitted in real time to a dedicated video processing unit, providing real-time and detailed image information for a wide range of complex video AI applications.
A large-area sensor and an ultra-wide-aperture lens design are employed to increase light throughput; combined with the ultra-sensitive noise-reduction technology of the AI-ISP, low-light performance is improved by fivefold, enabling full-color image output in low-light environments.
The stepper motor has a service life of 1 million cycles, which is five times the service life of a conventional brushless DC motor, making it suitable for applications such as counter-drone systems that require frequent zoom focusing.
The precision-tuned optical axes ensure that the optical-axis deviation for both wide-angle and telephoto modes does not exceed 10 pixels.
The product measures only 320 mm in length and weighs just 3,200 g, resulting in a smaller footprint compared with similar products.
A 30% reduction in weight and a 50% reduction in mass significantly alleviate the load on the gimbal, while also lowering gimbal costs and construction challenges, thereby achieving a seamless integration of high performance and lightweight design.
