My house in the community was broken into by thieves, and then all the wires of the main power supply were unplugged. Is it related to property?

First of all, the person directly responsible should be a thief. Call the police first, and the police will find the thief. If the thief is not caught, the property is responsible for the losses caused by the safety of the community. This responsibility depends on whether the property security facilities are complete and whether the security measures are in place. If the facilities are complete and the measures are in place, it is still inevitable, and the property is basically irresponsible. If the security is not carried out in accordance with the property service contract and the owner is stolen, he shall be liable for compensation. After reporting the case, you can ask the police to retrieve the surveillance video of the community. If you just installed the equipment and didn't monitor it as you guessed, it means that the property service is not in place, so you can sue the property and let it compensate your losses.
