3.3 Example - Carplate recognition system in car park

Carplate recognition system is an example of the integration of access control and surveillance system. It is commonly found in residential and commercial developments. The operational mechanism is divided into few parts. Firstly, the CCTV cameras installed on the entrance gate of the car park will capture the image of the carplate, as well as the image of the whole car. The images will then transfer back to the survaillance system in the security room through cat6/ cat6E cables installed inside the carpark. The cables are installed inside cable trunkings to provide mechnical protection and prevent intentional or unintentional damages. After receiving the images, the timeline and images will be recorded for security purposes. The carplate image will then go through an automatic system that can recognize the registered carplate through the images. For carplates that are registered, a singal will be sent for the car gate to operate. The car gate will open through the access control system through the signal cables and the registered cars can enter the car park. For carplates that are not registered, or when the images cannot be recognized, a signal will be sent to the security panel or computer inside the security room to notify the security guard inside. The security guard can operate the access control system manually to allow the cars entering the car park as visitors, or registered occupants if the system cannot recognize the carplate this time. The datebase of carplates can be saved in cloud system which can allow sharing among mutiple carparks for the database.

Example of companies that provides carplate recogntion system includes Vitronic, DKSH, NEC and Zkteco, etc. Examples of developments in Hong Kong that utilizes carplate recognition system includes Racing Club headquaters, Racing CLub cluhouses, the Traffic Branch Headquaters of Hong Kong Police Force, etc.
