How can some small scale department stores in rural areas prevent theft?

Some time ago, I went back to my hometown, after the countryside where I used to study in junior high school, the countryside is very different from before, it was difficult to find a commissary before, and it was difficult to walk a long way to have a department store, and every week I had to write down the items I needed on a blank piece of paper, and when I had time, I would purchase them together, which was very inconvenient.

Now the countryside is different, there are several haberdashery stores in a village, although the specifications are not very large, but the things are very complete, basically the daily necessities can meet everyone's needs. The houses in the countryside have a great feature, the neighbors will be separated from each other by a certain distance, some are at the bottom of the mountain, some are beside the road, some are at the entrance of the village, and some are at the end of the village, scattered and separated.

How do these small-sized department stores prevent theft? In my opinion, it would be good to do the following measures.

1.Install surveillance, install surveillance around the department store, especially in important exits and doorways, there are thieves to patronize, his every move is monitored and filmed, so that the thief patronizes, but also monitored the whole process, after the police, the police can investigate the work according to the monitoring screen, and can also provide powerful clues to track down the thief.

2.Installing an alarm system in the store, it can also be understood as installing some alarms that will make a sound, only the thief will automatically sound the alarm, the thief steals something, the heart is empty, and the sound of this alarm will definitely be very panicked, and finally flee.

3.Anti-theft nets are installed on the doors and windows of department stores, so that thieves are not so easy to enter.

4.At night, it is best for someone to stay in the store in the department store, and the thief knows that there are people living in the store, so he does not dare to act easily, and he should prepare some anti-thief tools in the store, such as electric rods and chili water, which must be prepared in case of thieves coming in, and also be prepared for defense.

Do the above points well, you don't have to worry about thieves coming, you can't hurt people, and you can't do without the heart of preventing people.

I'll make one of my little suggestions. First of all, you can install some reflective mirrors, so that when you buy something, you can see the customer's behavior through the reflection of the mirror. Secondly, you can install some cameras
