Is Your Business Door Security Good Enough? 7 Security Gaps to Check
Are you sure every door at your Chicago business is properly secured?
Your main entrance may be protected while a side door, employee entrance, loading dock, or rear door creates a security gap.
Quick answer: Commercial door security should combine access control, door-entry technology, video surveillance, intrusion detection, and regular system checks based on the needs of your property.
7 Business Door Security Gaps to Check
- Employees still use physical keys.
- Former employees may still have access.
- Side and rear doors are not controlled.
- Loading docks have limited security.
- Restricted rooms have weak access control.
- Cameras do not cover important entrances.
- After-hours doors are not properly monitored.
Do You Need Better Access Control?
Access control lets you decide who can enter specific doors and areas. Businesses can use key cards, mobile credentials, PINs, electronic locks, or other access technologies.
