Intercom system of entrance guard

Abstract

The system is set at the entrance of community for use in making communication between the visitors and the inhabitant living in the community and opening and closing the door of the entrance. The CPU in the system is separately connected to the database, the dialing key board, the display module, the network audio processor and the network interface. The database is used to save the code of inhabitant, the network register number and the identification code. The CPU is used to receive the code of inhabitant inputted from keyboard, and to read out the network register number of the inhabitant from database, and to access the network through network interface, and to put through the inhabitant end or the system operator in order to make the visitors communicate with the inhabitant by a email or a conversation, or a network phone, or a video phone.

Description

technical field [0001] The invention relates to an access control intercom system, in particular to an access control intercom system operated through the Internet and a related operation method. Background technique [0002] In today's increasingly urbanized society, communities and buildings have become the best choice for limited land resources. However, due to the large number of residents in these communities and buildings, there are many people entering and leaving. It is not easy to manage and control, and there are safety concerns. A typical approach is to set up a guard room in the community or building access area, and use the walkie-talkie to contact the residents to confirm the identity of the entering and exiting personnel. In order to further prevent the disturbance or entry of non-resident personnel, it can be installed at the entrance or elevator Identification device for enhanced security. [0003] However, in the actual situation, there are shortcomings, t...

Problems solved by technology

[0003] However, in the actual situation, there are shortcomings, that is, when the residents are not at home or temporarily unable to answer the intercom, the guards will not be able to judge the identity of the visitors through the residents. Although the community and the building will require the residents to provide a contact number, however This kind of practice has virtually increased the risk of residents' personal privacy exposure. Therefore, the inventor's Chinese Taiwan Patent Announcement No. 577032 has proposed a kind of "access control intercom system", which mainly has a built-in database in the access control intercom system to store residents. Indoor / mobile phone number for visitors to get in touch with residents through the public network exchange. At the same time, it can also provide residents with dial-up access to open and close the community door. It has excellent functions

However, the inventors found that although the invention uses the public network to overcome many inconveniences, the cost of making calls through the public network is also relatively high. Moreover, it is difficult to achieve video effects in line with economic principles by using the public network, so the resident cannot use the public network. To confirm that the visitor is correct, and greatly restrict the security function
