1. Camera failure

这种情况的出现大多数是雷电引起的，由于户外道路环境复杂，不是很容易建设防雷和接地系统，尤其是接地，很多路段的地质环境可能根本不具备4欧姆的接地条件；另外主要的原因就是供电系统出问题，由于设计的线路长而复杂，很容易造成摄像机的断电；还有就是摄像机长期在户外工作超过一定的使用寿命之后自然失灵的。因此，要解决这些问题需要分别对待。

This happens most is caused by lightning, because the outdoor road environment is complex, it is not easy to construction of lightning protection and grounding system, especially the ground, many sections of the geological environment may not have 4 ohm ground conditions; and the main reason is the power system problems, due to the design of the lines are long and complex that is very easy to cause the camera power; there is a camera failure after long-term outdoor work over a certain service life of nature. Therefore, to solve these problems need to be treated separately.

2、画面模糊不清

2. The picture is blurred

道路监控系统的建设通常因为成本的原因，不是所有的摄像机都是高清摄像机，或者百万像素的网络摄像机，再加上每只摄像机都有一个合理的监控范围，在监控范围内的监控画面是清晰的（取决于镜头的焦距），超过这个范围，监控的就会因为过小而模糊不清。通常我们理解的摄像机的监控距离不会超过1500米，那么假如两只摄像机的距离超过了3000米，我们就很难确保所有的目标都可以被清晰地监控到。就算是在合理的清晰监控范围内也会出现画面模糊不清的现象，主要是外界环境的影响比较大，比如雷雨天、雨雾天、夜间，摄像机的监控效果是要大大打折扣的。

The construction of road monitoring system usually because of cost reasons, not all cameras are high-definition cameras, or megapixel network camera, plus each camera has a reasonable range of monitoring, monitoring in the monitoring range is clear (depending on the focal length of the lens), more than this range the monitoring will be blurred, because too small. Usually, we do not understand the camera's monitoring distance by more than 1500 meters. If the distance between two cameras is over 3000 meters, it is very difficult for us to ensure that all targets can be clearly monitored. Even if it is in a reasonable range of clear monitoring will also appear in a clear picture of the phenomenon, mainly the influence of the external environment is relatively large, such as thunderstorm, rain and fog day and night, monitoring camera is to greatly discount.

3、无监控录像

3. Non monitoring video

很多时候当发生道路交通事故的时候我们第一时间想到的就是看看有没有录像画面可以调用，大部分的情况下我们是找不到录像的。这最主要的原因是道路辅助监控并不是按照360度无盲区监控建设的，道路监控不可能像写字楼、工厂那样每隔20米甚至5米安装一只摄像机，那样的投资会过于昂贵。但只要发生交通事故的路段安装了摄像机，通过调用录像便于我们了解过程，处理各种各样的纠纷。如果每部车辆都安装车载监控系统的话就可以很好的解决这个问题，当然现在的公交车大部分都安装了车载监控系统。

Many times, when a road traffic accident happens, the first time we think of it is to see if there is any video to call. In most cases, we can't find the video. The main reason is that road auxiliary monitoring is not based on the construction of 360 degree blind area monitoring. Road monitoring can not be installed as a office building or factory every 20 meters or even 5 meters. The investment will be too expensive. But as long as a video camera is installed in a traffic accident, it is convenient for us to understand the process and handle a variety of disputes by calling the video. If every vehicle is equipped with vehicle monitoring system, it can solve this problem well. Of course, most of the buses are equipped with vehicle monitoring system.
