Physical Security Engineer
Design access control, video surveillance, and intrusion detection systems for facilities.
What Physical Security Engineers Do
Physical security engineers design the systems that control who can go where and detect unauthorized access or intrusion. Access control systems (per UL 294) include card readers, electronic locks, access control panels, and visitor management systems. Video surveillance systems involve camera placement for optimal coverage, video management software (VMS), and network/storage infrastructure for video retention.
A key skill is the ability to perform a threat and vulnerability assessment to understand what needs protecting, then design layered security measures (the "layers of protection" model). Physical security engineers work closely with IT/network engineers (IP cameras and access control run on the network), electrical engineers (power for devices), and architectural teams (door hardware, openings).
The field is being transformed by AI-powered video analytics (automatic license plate recognition, crowd analytics, facial recognition), cloud-based access control, and mobile credential technology. Physical security engineers increasingly need to understand cybersecurity as physical security devices become networked systems with cyber vulnerabilities. CPP certification from ASIS International is the gold standard credential.

How long does it take to become a Physical Security Engineer?
Technical background → PSP or CPP certification → 5+ years experience → senior/principal roles
Is Physical Security Engineer a good career?
Physical security engineers design integrated security systems including access control (PACS), video surveillance (CCTV/IP cameras), and intrusion detection for buildings and critical infrastructure. They apply security principles to protect people, assets, and information while balancing operations and user experience. Demand is driven by ongoing infrastructure, construction, and technology work, and pay rises substantially with experience and licensure — from $70,000–$90,000 to $140,000–$170,000+.
