1 System function

The main functions of OriFire ST3.5 fixed point high-definition speeding evidence system: All-weather and real-time monitoring the moving targets on a road, when a speeding goal enter into the region of detection，the system will automatically snap the speeding target and generate the information database of the violation target. The clear picture of snapping auto-relates the violation evidence information of the vehicles including the violation location, violation time, the measured speed, the limit speed value of the road, the percentage of speeding etc. The picture of violation vehicles can be downloaded by U flash disk at the front-end of the system, and also can be transferred to the management center by the network for browsing and outputting.

2 System features

OriFire ST3.5 fixed point high-definition speeding evidence system has the following eleven great performance features:

1）The systems combines the advantages of the similar products on the market today for design, highly integrated, stable and reliable performance, easy installation and debugging, low maintenance costs.

2）The system software can compatible with a variety of network media, can diagnose automatically the working status of all front-end monitoring sites and can also control them from back-end of the management center.

3）To use professional high-definition video camera, snap a very clear picture. The horizontal resolution of it up to 520 TV lines，10.6 percent higher than 470TV lines of ordinary camera.

4) Using professional speed gun, less power consumption(2.16W)，faster response(20ms), more adaptive environment(-30℃-70℃）。

5）The advanced technology of determine the direction of the goal of the radar, you can filter on the vehicles, only to snap one-way car, significantly reduced the rate of false pictures.

6）High-performance signal processing technology improves the radar gun accuracy, up to 0.1 km / hour.

7）Using industry level computer, lower power consumption, running faster. CPU: Pentium M 1.7Ghz, Memory: 512M.

8）Large-capacity storage, 80G hard disk can store 2,000,000 pictures.

9）Unique advanced image processing algorithms and multi-conditions discrimination, greatly reducing the rate of missing shot and false shot.

10）System software( front-end and back –end) is user-friendly, simple, stable and reliable, any one can operate it soon.

11）With an one key recovery system, when the system collapses, it can automatically restore within 10 minutes.
