Good Quality Video Camera Detector With Wireless Connect Detector
Good Quality Video Camera Detector
Good Quality Video Camera Detector meets with customer reality needs. As detection equipment. Its function and the technical requirement is higher. But in the meanwhile. It cost is very expensive. For example, the requirements for video vehicle detectors for traffic information services, traffic flow statistics, and analysis are different from those for video vehicle detectors used for traffic signal control and should be clearly defined in the standard. But the video camera detector main detects the area whether have cargo or not. In the future development, we will develop in this direction in this direction. Quantitative detection, such as traffic flow, vehicle violation event capture rate, etc. But for some indicators, it is more difficult for the event to achieve objective evaluation, such as the print speed of the vehicle. Different test methods should be developed according to different directions to use.
For wireless video camera detector, the biggest problem is the image source. For a hot sale video detector that can achieve the detection requirements of an image source, there may be a serious drop in the index for another image source. The more obvious examples are day and night, with shadows and no shadows. Therefore, the image source should be the collection of typical images. The test of an indicator should be performed on all objects of a typical image collection. The ability of the tested product to adapt to engineering practice depends on the scientific and typicality of the image source set. And representative. For a typical image source set, key parameters such as the lowest output signal to noise ratio, resolution, and dynamic range should be specified. Characterizing video vehicle detection technology, good quality video camera detector is a large area, multi-function detector with completely different characteristics and detection capabilities than other vehicles detectors. It should reflect its unique detection function in the standard. Such as queue length, cross-line driving, etc. The video camera detector voltage was 12-42VDC.
The advantage of video camera detector:
1. The camera detector is flexible in setting, easy to install, easy to use, and does not damage the road surface. There is no need to close the driveway during maintenance.
2. The accuracy of speed measurement and the accuracy of traffic volume counting can basically maintain a high level. At present, the speed measurement accuracy of the commonly used video vehicle detectors in China is above 95%, and the traffic volume counting accuracy is generally around 98%. After many on-site inspections, it is found that after using a high-sensitivity camera with strong light suppression, the same detection accuracy as in the day can be achieved without road illumination at night. It is only at dawn and dusk that the background environment brightness changes significantly and the vehicle's light switch state is inconsistent, the detection accuracy is poor.
3. The good quality video camera detector image can be connected to the monitor of the monitoring center, which can display the traffic flow information such as speed and traffic volume in real time, and provide a large amount of monitoring information for traffic monitoring.
