The property management assistant is a special app tailored for the property and used to manage community security and community personnel. It integrates functions such as commute settings, key list and key bag to open the door, community list, view video and visitor photo. The property can use the property management assistant to open the door, video and photo of the visitor to the community access control, and can manage the housing information of the community. You can view the incoming calls of the access control machine and the person who calls the access control to open the door.
