The designated license plate information is entered into the system, and the system automatically reads the license plate of the passing vehicle and queries the internal database. For vehicles that need to be automatically released to drive electronic gates or barriers to allow them to pass, warnings will be given to other vehicle systems and handled by on-duty personnel. Can be used for special units (such as military administrative areas, confidential units, key protection units, etc.), road and bridge charge bayonet, and advanced residential areas.

Strong light shielding: Based on the low-light color camera, through the function of the software, the brightest part of the image is blocked. In traffic monitoring, the headlights are generally blocked by strong light, so that the license plate can be captured more clearly. However, the biggest drawback of this camera is that the software is not clear, the brightest part of the image is unclear, it is possible to block the license plate number, and it is impossible to handle the capture of high-speed moving objects. At present, domestic cameras do more in the light shielding, the effect of all parties reflected.
Adjustable electronic shutter: For high-speed movement of objects to capture (the speed of the car on the highway is generally more than 70KM / hour), you can achieve clear capture by reducing the electronic shutter speed, usually through manual adjustment. However, the biggest problem with this method is that daytime and evening illumination are different. It is necessary to set two shutter speeds to adapt to daytime and nighttime monitoring respectively.
Wide dynamic function: This is the best way to solve the impact of the lights on the capture, wide dynamic was first proposed by the Panasonic company. When the background light is too bright, ordinary cameras cannot solve the display problem of light and dark images.

Drivers using existing loopholes in the system will use the loopholes in the existing toll collection system to avoid evading fees. License plate recognition technology is the fundamental method to solve such problems.
- Calculate vehicle travel time
According to the latest statistics, by the end of 2014, the market demand in China's parking lot will exceed 3.7 billion yuan, and the next five years will surely be the golden period for the intelligentization of parking lots. Automatic license plate recognition is the most valuable market in the future parking market. With the integration of high-definition and intelligence, license plate recognition can also help us solve more problems in our lives.
License plate recognition integrated machine has excellent imaging control, can automatically track light changes, effectively inhibit the smooth light and backlight, especially at night to suppress the interference of car headlights, thus clearly capturing the license plate; and for the moment there is no license plate or serious damage to the license plate The situation can also realize intelligent traffic management; in addition, offline operation is also a unique advantage of the license plate recognition integrated machine, which can effectively improve the efficiency of vehicle access.
