车牌识别云台摄像机通过光抑制屏蔽，电子快门调节，宽动态功能等来实现抓拍车牌：
PTZ camera for license plate recognition can capture license plate by light suppression and shielding, electronic shutter adjustment and wide dynamic function
强光屏蔽：在低照度彩色摄像机的基础上，通过软件的功能，把图像中最亮的部分遮挡。在交通监控中，一般可将大灯的强光遮挡，从而将车牌较清晰的抓拍下来。但是这款摄像机最大的缺点就是软件分辨不清，对于图像最亮部分界定不清，有可能将车牌号码也遮挡，同时无法处理高速运动物体的抓拍。目前国产摄像机在强光屏蔽方面做的比较多，效果各方反映不一。
Strong light shielding: Based on the low illumination color camera, the brightest part of the image is blocked by the function of the software. In traffic monitoring, the strong light of the headlight can be blocked to capture the license plate clearly. But the biggest disadvantage of this camera is that the software can't distinguish clearly, the brightest part of the image can't be clearly defined, the license plate number may also be blocked, and the capture of high-speed moving objects can't be processed. At present, domestic cameras do a lot in the aspect of strong light shielding, and the effect is different.
可调电子快门：对于高速运动的物体抓定州苗木  保定网站建设 保定电动门 保定空压机 化粪池模具 微型蠕动泵 上海起帆电缆拍(高速公路上的汽车车速一般都在70KM/小时以上)，可以通过降低电子快门速度来实现清晰抓拍，一般都是通过手动方式调整。但是这种方式最大的问题就是白天、晚上的照度不一样，必需设置2个快门速度来分别适应白天和晚上的监控。
Adjustable electronic shutter: for capturing high-speed moving objects (the vehicle speed on the highway is generally above 70km / h), you can reduce the speed of the electronic shutter to achieve clear capture, which is generally adjusted manually. But the biggest problem of this way is that the illumination is different in the daytime and at night. Two shutter speeds must be set to adapt to the monitoring in the daytime and at night.
