How to reduce the burden of residential property management? Improve the efficiency of property management?

Residential properties often go to the building to post notices, but also register residential visitors, which is really a heavy burden. Some practical tools can be used to help improve management efficiency. For example, using "Home Guard", all kinds of announcements and maintenance notices can be sent directly to the owner's mobile APP on the computer, which saves the trouble of running the building. Visitors to the community can also be confirmed and released remotely by the owner directly through the APP, and security guards can also avoid registering visitor information to improve work efficiency.
