We came up with an all round system to cope with the problems and all situations discussed above to make sure to both the efficiency and security. In general, the system has two ends and one data processing unit: a frontend at the gate, capable of biometric recognition and car license recognition as well as sending communication request to the house owners; a client end which can be used to manually verify visitors and control the gate to open. In terms of the means by which people enter the gate, we considered two situations: whether s/he is driving a car or not. In terms of the type of visitors entering the gate, we came up with three possible scenarios.

 

When a house owner is driving a car to the entrance. The camera on the gate will capture the car's license plate number and figure out whether s/he is the resident of the estate. After verification, the system will automatically open the gate for her or him. Since the camera can capture the car from within a certain distance, the car doesn't have to stop and wait for the gate open. On the other hand, if the house owner is walking instead of driving a car, s/he can enter the gate either through fingerprint or password recognition. Figure 1 illustrates this scenario.

Figure 2 illustrates the situation when some relatives or friends of the owner are going to visit, the owner can predefine these people. For example, he'd like to meet his friend Tom tomorrow and Tom says he will drive a car with license number 12345, and then the owner can input this number into the system to reserve that car for tomorrow's access permission. When his friend drives car at the gate, the system will automatically open the gate for him. If his friend prefers walking to driving, then he can set a voice password or something like that and his friend can use this to get in.

Figure 3 illustrates the situation when some stranger comes, that stranger has to first select the house he's going to visit on the screen at the gate end. The gate end then sends communication request to the corresponding house owner. After the owner receives the voice and/or image information at the client end from the gate end, s/he will decide whether to open the gate or not.
