How to guard against theft in tobacco and liquor stores? Is there any good way?

Now there are two ways to prevent theft in tobacco hotels.

One is video surveillance anti-theft and the other is anti-theft alarm system.

Monitoring has little effect on theft prevention. Many times, we only call out the monitoring investigation after finding the stolen goods, which can't solve the problem from the root and doesn't play a key role in anti-theft. As for the alarm, if there is illegal invasion, you can give an early warning. Whether it is true or not requires on-site confirmation. If something really happens, it is difficult for a person to control the situation, and there is also the risk of accidental injury in life.
