Product Introduction
CM8855EM
Defining New Heights of Vision with Excellent Hardware
Featuring a 1/1.8" ultra-large sensor with high sensitivity, paired with an F1.4 large-aperture lens and 55x optical zoom (f: 6-330mm), this camera combines a powerful AI main control chip to deliver unparalleled image quality day or night, at any distance.
Deep AI Applications for Multiple Scenarios
Powered by a high-performance AI controller chip, the camera features built-in deep learning-based recognition algorithms for people, vehicles, smoke, and fire, enabling comprehensive and advanced intelligent security solutions. These systems are widely deployed in perimeter protection, fire prevention, and disaster mitigation projects.
MIPI network dual output
The MIPI interface enables real-time transmission of 4K@30fps lossless video data to a dedicated video processing unit, delivering detailed and real-time image information for sophisticated video AI applications.
Low Light Full Color
The design incorporates a large-area sensor and ultra-wide aperture lens to maximize light transmission, paired with AI-ISP's hypersensitive noise reduction technology. This achieves a fivefold improvement in low-light performance, delivering full-color image output in dim environments.
Better environmental adaptability
The proprietary temperature compensation technology ensures 7x24-hour focus performance unaffected by temperature fluctuations. Featuring near-infrared optical fog removal, multi-axis digital stabilization, and heat wave elimination, it delivers stable high-quality video output regardless of fog, vibration, bumps, or scorching heat.
contraption
With a size of only 175.84mm and a weight of only 970.5g, the product greatly reduces the load pressure on the pan-tilt table, while reducing the cost and construction challenges of the pan-tilt table, achieving a perfect combination of high performance and lightweight design.
