线圈是用来触发像机启动的开关,过一个线圈启动一次。两次拍摄证明你车在红灯后还是移动的,所以你的钱包 ...
看看第二张照片是不是过线圈触发的:

If a vehicle passes onto the loop when the loop is activated, the loop will monitor the passing of that vehicle. If the vehicle stops on the loop, no photo is taken. If the vehicle clears the loop by moving forward, the system determines that a vehicle has entered the intersection against a red light. A photo is taken. A second photo is taken about 1 second later. Sometimes there is a flash associated with taking the photo.
说的很清楚了,第一张是红灯时候通过线圈触发,第二张是1秒以后拍的
例子:第二张照片车子都在路中间了,路中间哪里来的线圈?
