What should factory security guard pay attention to at night?

Stay awake and strengthen patrols. No matter how many people are on duty, we must stay awake. After all, security has a great responsibility, especially when patrolling. Last year, I read the newspaper of Shi Sheng Security in Tai 'an, and found that they did a good job. The joint police cracked a major copper tube theft case of a Shanghai customer, which should not be false when it was reported in the newspaper.
