Are the security posts and patrol posts in the office building the positions for recruitment?

Hello; Security and patrol should be the same department, but the focus of work is different. Safety is to protect safety. There are more patrol tasks. It is necessary to check all kinds of abnormal phenomena, such as whether the personnel in each department are abnormal, whether the fire fighting equipment is in good condition, whether the windows in each department are abnormal, whether the electrical appliances and lines are abnormal, and whether there is any peculiar smell or abnormal sound. All right.
