25Frequently Asked Questions
PSP (Physical Security Professional) is focused on physical-security assessment, application and design. CPP (Certified Protection Professional) is the senior, broader credential in security management. Many professionals earn PSP first and CPP later as they move into management.
In most states, yes. Installing alarm, access-control and CCTV systems generally requires a state alarm or low-voltage license, often with a company/qualifier license plus individual technician registration. Requirements vary by state.
ESS (Electronic Safety & Security designer) is BICSI’s credential for designing electronic security systems — access control, video surveillance, intrusion detection and the supporting network infrastructure.
Modern security systems are IP/network-based, so a baseline IT-security credential like Security+ is increasingly valuable for cybersecurity of cameras, access control and the networks they run on.
Concept Explainers
12A sensor tripping isn't a caught intruder. Illustrated three-stage flow — detection, video verification, and threat assessment — showing why skipping a stage causes alarm fatigue and under-informed responses.
Why combining two unreliable sensors makes one reliable one. Illustrated AND-logic comparison showing how a dual-tech sensor's PIR + microwave pairing filters out HVAC drafts and sunlight that fool a PIR-only sensor.
Three dials, only two of which are settings. Illustrated comparison showing why the identical camera at the identical resolution and frame rate can produce wildly different storage consumption depending on scene motion.
A turnstile detects tailgating with sensors while keeping the line moving. A mantrap makes it physically impossible with an interlock that never lets both doors open at once. Illustrated comparison of detection vs. physical prevention — and why the wrong pick is a real design mistake.
One device reports whether the door is physically open or closed. The other tells the alarm logic an exit was authorized, so free egress doesn't trip a forced-door alarm. Illustrated signal-flow and four-scenario decision table showing why both are required at the same door.
Tailgating happens without the authorized person ever knowing. Piggybacking happens because they deliberately held the door. Illustrated comparison of an unwitting breach vs. a willing courtesy — and why only one of them is fixed by better sensors.
A single strong fence is a single point of failure — once it's breached, nothing else stands in the way. Illustrated comparison of a perimeter-only facility vs. genuine layered security, and why relying on one impressive boundary is a real design mistake.
A stolen card plus a memorized PIN is genuine multi-factor. Two memorized PINs is not, even though both look like "two credentials." Illustrated comparison showing why combining different factor types — not doubling one — is what actually stops an attacker.
The same power outage, same door, two opposite hardware behaviors on purpose. Illustrated branching diagram showing why fail-safe unlocks for egress while fail-secure stays locked for security — and why fail-secure is often the deliberately correct choice, not a lesser one.
Access control runs continuously, granting or denying passage in real time whether the building is occupied or not. Intrusion detection only watches while armed. Illustrated comparison showing the same door contact behaving completely differently under each system's logic — and why having one never makes the other redundant.
The real difference isn't resolution — it's where the picture gets digitized and how many cables that costs at every camera. Illustrated signal-path comparison of coax-plus-separate-power analog cameras vs. single-Cat6/PoE IP cameras, and why modern analog HD formats have closed the resolution gap.
The choice isn't which is objectively better — it's where you want the risk to live: a box on-site that can be stolen, or a subscription that depends on the internet staying up. Illustrated architecture comparison of on-prem NVR storage vs. cloud VSaaS, covering bandwidth, latency, cost, and resilience trade-offs.
