Who should I look for to repair the problems in the gate monitoring of the commercial building?

The property management department is responsible for maintenance. However, for some commercial corridors with industry committees, the installation of monitoring systems is the responsibility of the relevant owners' committees. But no matter which subject is responsible for the installation of the monitoring system, they will also undertake the maintenance work when the monitoring system fails; However, it should be noted that the "maintenance work" undertaken by the property management or industry committee is not the real monitoring system maintenance, but they are responsible for contacting the installation service team of the monitoring system for after-sales maintenance services. Failure of commercial corridor system | Monitoring camera installed in residential area | Monitoring system installed in residential area | Monitoring system failure. When there is a need to install the monitoring system, in order to ensure the after-sales service in the later stage, when selecting the service team in the early stage, you must choose qualified and powerful enterprises to provide services for you, so as to avoid the situation that the monitoring system fails but cannot be repaired in the later stage.
