根据城市道路高清视频监控的实际需要,在选择摄像机时可参考以下的建议:1、采用CCD传感器。当前,在CMOS技术还未十分成熟的情况下,比较CCD与CMOS两种感光芯片,CCD传感器在灵敏度、分辨率、噪声控制、高质量图像输出、动态影像表现方面都要优于CMOS。尤其在城市道路晚上光照条件较差的情况下,CCD摄像机的成像效果要好于CMOS摄像机,所以建议采用CCD作为高清摄像机的感光芯片。2、为满足全天候治安监控的需要,摄像机应具备低照度功能,以便在黄昏和夜间照度较低的环境下也能获得较为清晰的视频图像。3、高清视频监控需要达到720P/1080P分辨率,逐行扫
According to the actual needs of urban road HD video surveillance, the following recommendations can be made when choosing a camera: 1, the use of CCD sensor. At present, compared with CCD and CMOS sensors, CMOS sensors are superior to CMOS in terms of sensitivity, resolution, noise control, high-quality image output and dynamic image performance even under the condition that CMOS technology is not yet mature. Especially in the urban road at night under poor lighting conditions, the CCD camera imaging better than the CMOS camera, it is recommended to use CCD as a high-definition camera sensor chip. 2, in order to meet the needs of law and order monitoring around the clock, the camera should have a low light function, in order to obtain a clear video image in low dusk and night illumination environment. 3, HD video surveillance needs to reach 720P / 1080P resolution, progressive scan
