The five levels of physical security are minimum, low, medium, high, and maximum.
Here’s what each one entails:
Minimum security includes a basic security system, door and window locks, and an alarm system, among other things.
Low security includes reinforced doors, locks, window bars, security gates, security lighting, and so on.
Medium security includes low security systems and devices + surveillance cameras, loud sirens, remote monitoring, fences, unarmed guards with basic training skills.
High security measures include cutting-edge surveillance equipment, biometric locks and barriers, a perimeter alarm system, gates, access control, security lighting, armed guards with extensive training, security dogs, and collaboration with law enforcement.
Maximum security includes tamper-proof, high-level alarm system—remote monitoring and surveillance with tactical response, 24/7 security personnel with high-level combat training and problem-solving skills.
