Remote control, monitoring and maintenance of multi-site municipal facilities is an important task that can improve efficiency, reduce costs, optimize services and ensure safety. To accomplish this task, we need to provide stable, reliable hardware solutions, including a variety of devices and systems, such as sensors, cameras, controllers, communicators, etc. At the same time, we need to configure devices and respond effectively to real-time information, monitor and adjust the status of devices in a timely manner, process and analyze data, and prevent and resolve failures.
