TPS Security Technology & Equipment 1 — Questions and Answers
Question 1: What is the purpose of a two-way radio in security operations, and what are the basic protocols for its use?
- Real-time communication between officers and supervisors — protocols include identifying yourself, being concise, waiting for the channel to clear, and using plain language or agreed codes (Correct answer)
- Monitoring police radio frequencies for law enforcement activity
- Communicating with the DPS Private Security Bureau during incidents
- Recording all verbal communications for incident documentation purposes
Correct answer: Real-time communication between officers and supervisors — protocols include identifying yourself, being concise, waiting for the channel to clear, and using plain language or agreed codes
Two-way radios enable coordination between security personnel. Good radio protocol means being brief, clear, and professional to keep channels available for urgent transmissions.
Two-way radios are essential tools for security team coordination. Basic radio protocols include: (1) Wait for the channel to clear before transmitting; (2) Key the mike and wait a second before speaking; (3) Identify yourself with your call sign; (4) State your message clearly and concisely; (5) Say 'over' when finished and awaiting a response; (6) Avoid unnecessary transmissions that clog the channel.
Question 2: What is a 'body-worn camera' (BWC) and what are the benefits of its use by security officers?
- A wearable video recording device that documents interactions — benefits include accountability, evidence collection, and deterrence of misconduct by both officers and subjects (Correct answer)
- A camera worn for covert surveillance operations only
- A device that transmits live video to law enforcement during incidents
- A required DPS equipment item for all commissioned security officers
Correct answer: A wearable video recording device that documents interactions — benefits include accountability, evidence collection, and deterrence of misconduct by both officers and subjects
Body-worn cameras document officer interactions, providing accountability, evidentiary value, and deterring misconduct by all parties.
Body-worn cameras (BWCs) are increasingly used by security organizations for: (1) Evidence collection — footage documents incidents for law enforcement and legal proceedings; (2) Accountability — officers know their actions are recorded, which promotes professional conduct; (3) Deterrence — subjects who know they are being recorded often behave more cooperatively; (4) Dispute resolution — footage resolves conflicting accounts of incidents.
Question 3: What is a 'metal detector wand' and how is it used in security screening?
- A handheld electronic device that detects metallic objects on a person's body — used by slowly passing it over the body while monitoring for audible or visual alerts (Correct answer)
- A device that tests whether metal objects are magnetic or non-magnetic
- A weapon used to subdue metal-bearing threats
- A calibration tool for fixed walk-through metal detectors
Correct answer: A handheld electronic device that detects metallic objects on a person's body — used by slowly passing it over the body while monitoring for audible or visual alerts
Handheld metal detector wands are passed slowly over a person's body to detect concealed metallic objects such as weapons. An alert indicates a metallic item in that area.
Handheld metal detector wands work by generating an electromagnetic field. Proper technique involves: obtaining consent before screening; passing the wand slowly and systematically over the body (approximately 1-2 inches from the surface); pausing and repeating over areas that triggered an alert; and following up when a potential weapon is detected. All screening must be conducted respectfully and in compliance with the site's policy.
Question 4: What is the purpose of a 'panic button' or 'duress alarm' system in a security context?
- To allow officers or employees under threat to silently alert security or emergency services without alerting the threat (Correct answer)
- To sound an audible alarm whenever a security officer is on patrol
- To automatically lock all doors and windows in a facility
- To notify the DPS when an officer uses force
Correct answer: To allow officers or employees under threat to silently alert security or emergency services without alerting the threat
Panic buttons enable silent distress signals that alert security or emergency services when an officer or employee is in danger and cannot vocalize for help.
Panic buttons (duress alarms) are installed in locations where employees face elevated security risk — banks, retail service counters, healthcare facilities — and are carried by some security officers. When activated, they silently alert a monitoring station or trigger a law enforcement notification without alerting the threatening person.
Question 5: What is the purpose of a 'vehicle barrier' (such as bollards or jersey barriers) in physical security?
- To prevent unauthorized vehicles from entering protected areas and to protect pedestrians from vehicle-borne attacks (Correct answer)
- To mark parking spaces in a client's parking area
- To slow vehicle traffic on public streets near a facility
- To provide a resting area for security officers on patrol
Correct answer: To prevent unauthorized vehicles from entering protected areas and to protect pedestrians from vehicle-borne attacks
Vehicle barriers physically prevent unauthorized vehicle entry and protect people from vehicle-as-weapon attacks, which have become a significant security concern.
Vehicle barriers — including fixed bollards, removable bollards, jersey barriers, and crash-rated gates — are designed to stop or slow unauthorized vehicles. Their security purposes include: (1) Perimeter protection — preventing vehicles from entering restricted areas; (2) Standoff distance — keeping vehicle-borne IEDs at a safe distance from structures; (3) Vehicle-as-weapon protection.
Question 6: What is a 'CCTV system' and how does it differ from a 'video analytics' system?
- CCTV (Closed-Circuit Television) is a passive recording system; video analytics adds software that automatically detects and alerts on specific behaviors or conditions (Correct answer)
- CCTV is a real-time monitoring system; video analytics records footage for later review only
- CCTV is used only for exterior monitoring; video analytics is for interior use only
- CCTV requires human monitoring 24/7; video analytics does not require any human oversight
Correct answer: CCTV (Closed-Circuit Television) is a passive recording system; video analytics adds software that automatically detects and alerts on specific behaviors or conditions
CCTV records and displays video from cameras. Video analytics adds automated detection — the software flags specific events (loitering, perimeter breach) without requiring continuous human monitoring.
Traditional CCTV systems capture and record video footage from cameras, requiring human operators to monitor displays and review recordings. Video analytics systems add software that analyzes footage automatically, detecting specific behaviors and generating alerts for security personnel. Analytics allows one operator to effectively monitor what would otherwise require many operators watching many screens simultaneously.
