Do you charge by door or by car when installing access control in the old community?

According to the Property Management Regulations, the installation and maintenance costs of residential access control system should be borne by the owner. Charging by households can share the cost of access control system more fairly, and every owner can enjoy the security and convenience brought by access control system. Moreover, charging by households can better manage the entry and exit of people in the community and ensure the safety and order of the community.
