It's very simple

1. Install a camera, and you can see the working status of employees even if they are not in the store or there is no one to supervise them.

2. Invite people to make an unannounced visit to the field.

The method of the first camera has disadvantages. If the camera is too conspicuous, some employees will avoid the camera "fishing", and they will not be able to obtain evidence at any time. It is also impossible to stare at it every day.

It is suitable for all kinds of stores that need to provide services, such as restaurants, homes and other stores. If the unannounced visitor goes to the camera, the time is not fixed, and his identity is secret, it can also play a better role.

If the camera is used. If you want to get the delivery place quickly, choose Shenzhen, and then choose your district

If it is the second kind, I know that there is a company in Futian called Shangshuzi Information Consulting, which will do such unannounced visits. You can ask.
