How do you know that the safe at home has been tampered with by the property?

Through the passive lead seal when installing watches, we know that the strong electric box at home has been tampered with by the property.

If it is the original factory, it is not the original factory after replacement, and it is touched. If it is sealed by an electrician, there is no evidence that the watch has been passive.

There is a way to recover the number of electric meters.

First of all, turn off all the power in the house, plug in the power, and let all the appliances in the house be cut off. See if the meter is turning, and you'll know if anyone has touched it.
