The safety factor of the rolling gate is very low and there is a certain gap with the ground. It's easy to open with a crowbar. Just take off the plastic cover outside the door and knock off the lock with a screwdriver and a strong lock. I specialize in theft prevention. There are many examples of theft. Summarize several anti-theft methods of rolling gate:
1. Drill a hole in the post of the iron gate and tighten it at night. (physical anti-theft)
2. Install burglar alarm to scare away thieves and remind the owner. (technical anti-theft)
3, the monitoring cost is high, and it is impossible to identify the person who steals the face.
