SSP Security Technology & Systems 3 â Questions and Answers
Question 1: What does CPTED stand for in the context of physical security design?
- Crime Prevention Through Environmental Design (Correct answer)
- Controlled Perimeter Threat and Entry Detection
- Critical Physical Technology for Entry Defense
- Comprehensive Protection Through Exterior Deterrents
Correct answer: Crime Prevention Through Environmental Design
CPTED is a design philosophy that uses the built environmentâlighting, landscaping, sightlinesâto deter criminal behavior and reduce opportunities for crime.
Question 2: A security system sends an alarm signal even though no actual intrusion has occurred. This is called a:
- Missed alarm
- False positive (Correct answer)
- Nuisance alarm
- System fault
Correct answer: False positive
A false positive (false alarm) occurs when a security system triggers an alert without a real threat being present, often caused by environmental factors or equipment issues.
Question 3: In video surveillance, what does the term 'pan-tilt-zoom' (PTZ) describe?
- A camera that can rotate horizontally, vertically, and magnify the image (Correct answer)
- A multi-lens camera array covering 360 degrees
- A recording mode that alternates between cameras
- A compression standard for video footage
Correct answer: A camera that can rotate horizontally, vertically, and magnify the image
PTZ cameras can pan (rotate left/right), tilt (angle up/down), and zoom optically, allowing operators to track subjects and examine details remotely.
Question 4: Which type of barrier is designed to stop a vehicle weighing 15,000 lbs traveling at 50 mph and is rated K-12?
- A crash-rated bollard meeting ASTM F2656 K12 standard (Correct answer)
- A standard concrete jersey barrier
- A chain-link fence with barbed wire topping
- A cable barrier rated for pedestrian control
Correct answer: A crash-rated bollard meeting ASTM F2656 K12 standard
The ASTM F2656 (formerly DOS/SD-STD-02.01) K-12 rating certifies vehicle barriers to stop a 15,000 lb vehicle at 50 mph with minimal penetration.
Question 5: What is the primary vulnerability addressed by installing anti-passback in an access control system?
- Preventing a credential from being used twice in a row at the same entry point without an exit (Correct answer)
- Blocking tailgating via door timing alerts
- Encrypting card data during transmission
- Detecting cloned access credentials
Correct answer: Preventing a credential from being used twice in a row at the same entry point without an exit
Anti-passback requires that a credential used to enter a zone must be used to exit before it can be used to enter again, preventing credential sharing and piggyback entry.
Question 6: Which lighting type provides the best color rendering for security cameras monitoring outdoor areas at night?
- Low-pressure sodium (LPS)
- High-pressure sodium (HPS)
- Metal halide
- LED with full-spectrum output (Correct answer)
Correct answer: LED with full-spectrum output
Full-spectrum LEDs provide high color rendering index (CRI) values, allowing cameras to capture accurate colors for subject identification, while sodium lights distort color.
Question 7: What is the purpose of an uninterruptible power supply (UPS) in a security system?
- Provide continuous power to security equipment during utility outages (Correct answer)
- Regulate voltage spikes to prevent equipment damage only
- Encrypt power-line communications
- Synchronize clocks on all security devices
Correct answer: Provide continuous power to security equipment during utility outages
A UPS maintains continuous electrical power to security equipmentâcameras, access control panels, alarmsâduring power outages, ensuring system operation until backup generators start.
