Product Introduction
CM8855EM
Defining a new height of vision with excellent hardware
Equipped with a 1/1.8 "ultra large target surface and high sensitivity sensor, paired with an F1.4 ultra large aperture lens and 55x optical zoom (f: 6-330mm), combined with a powerful AI control chip, it always provides unparalleled image quality regardless of day, night, or distance.
Multi scenario AI deep application
With a powerful AI control chip, the camera is equipped with deep learning based recognition and alarm algorithms for people/vehicles/smoke/fire, achieving diversified and deep applications of intelligent security protection, widely used in perimeter protection, fire prevention and disaster reduction projects.
MIPI network dual output
Real time transmission utilizing MIPI interface's real-time performance 4K@30fps Lossless video image data is sent to a dedicated video processing unit to provide real-time and detailed image information for various complex video AI applications.
Micro light full-color
Adopting a large target area sensor and a super large aperture lens design to enhance light transmission, combined with AI-ISP's ultra sensitive noise reduction technology, the low light performance is improved by 5 times, achieving full-color image output in low light environments.
Better environmental adaptability
The original temperature compensation control technology ensures that 7x24 focusing performance is not affected by temperature fluctuations. Equipped with near-infrared optical fog transmission, multi axis digital image stabilization, heat wave elimination and other functions, it can stably output high-quality videos regardless of fog diffusion, vibration and turbulence, or high temperature and scorching.
exquisite design
The product size is only 175.84mm and the weight is only 970.5g, greatly reducing the load pressure of the gimbal, while reducing the cost and construction challenges of the gimbal, achieving a perfect combination of high-performance and lightweight design.
