• Aluminum garage doors are low-cost, light, rust-proof, and feature low-maintenance. They are prone to denting because aluminum is not strong and they are energy-inefficient since aluminum is a highly conductivematerial.
• Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
• Steel doors have become common and are available in a variety of sizes and styles, provide strength and security, are cost-competitive, and may have optional insulating value. Extra strength is available with two or three layers of galvanized steel with a low gauge number (23-24 gauge steel panels).
• Wood garage doors offer aesthetic appeal, but they are high-maintenance and may be expensive. Low-priced wood garage doors may warp and break easily.

The license plate recognition system is a special computer vision system with a specific purpose of the license plate. The license plate recognition system is not only applied in the parking lot, but also plays a very important role in the traffic field. It can be said that it is an important part of the intelligent traffic system. One of the main functional modules of the road traffic monitoring and management system of science and technology. It can be widely used in traffic flow detection, traffic control and induction, vehicle management in airports, ports, and communities, automatic charging without parking, and illegal vehicle monitoring such as red lights.
The license plate monitoring system not only has the above functions, but also records the appearance of the driver and the time the vehicle entered. If something unexpected happens, such as theft, it can also provide certain help for the police to solve the case through the monitored video. After installing the license plate recognition system at the toll parking lot, the above problem is very easy to solve. If the owner accidentally loses the ticket card, the management of the parking lot can check the time of entry and exit of the car through this system. Even the appearance of the license plate number and the driver can be seen, thus avoiding some unpleasant occurrences, improving the travel time, and enhancing the customer experience.
If the license plate recognition system is installed in these parking lots, the above problems can be solved. After the license plate recognition system is installed in the parking lot of the community and building, the parking lot manager can simply input the information of the resident's vehicle into the database, so that when the resident's vehicle enters the parking lot entrance, the system is verified. The owner’s vehicle information, which matches the information entered in the database, will automatically allow the vehicle to enter; if the vehicle information is not in the system's database, then the vehicle cannot enter.
The license plate recognition system can not only be used in places such as parking lots, but also can be installed on roads, and can also identify stolen vehicles traveling on the road. Of course, this requires the police to establish a database of stolen vehicles, and then connect this database to the monitoring system. As soon as the vehicle is monitored, the stolen vehicle can be notified to the police at the first time to provide assistance for the police's detection work. This system also has broad application prospects in the field of vehicle security and theft prevention. Based on its role, as well as various problems existing in various parking lots and transportation areas, for example, as the urban population increases, the number of vehicles will inevitably increase, and the problems will increase, and these problems will increase. It is impossible to rely solely on manpower to solve the problem. Therefore, the automatic license plate recognition system is more and more commonly used, and it is closely related to the development of society and people's living needs.
