The solution of the DAHUA controllers is very interesting. When there is a controller and a power supply unit and a battery in one box. But you were wrong with connecting 220v. ACS is a security system. But you can pull out the cable or flip the switch and the entire security system is turned off. Why, then, is the housekeeper on the box? The 220v connection and the switch must be moved inside the box.
