A CCTV system's field of view for a parking lot camera is being optimized. Which lens characteristic should a security consultant INCREASE to cover a wider area with a single camera?
Answer: Angle of view
A wider angle of view (achieved with a shorter focal length lens) covers more area, though it reduces image detail; balancing coverage and resolution is key in camera placement.
During a security audit, a consultant finds that the video management system (VMS) retains footage for only 48 hours. For a facility handling sensitive government contracts, what retention period is MOST commonly required?
Answer: 90 days
Many government and high-security facility standards require a minimum of 90 days of video retention to support post-incident investigations and compliance audits.
A security operations center (SOC) analyst notices a camera displaying 'video loss' during a critical evening shift. The FIRST action the on-duty security supervisor should take is:
Answer: Dispatch a guard to physically verify the camera and the area it covers
An immediate physical check of the camera and its coverage area is the first priority to determine whether the outage is a technical failure or a deliberate act to blind surveillance during a security event.
Which lighting type provides the BEST energy efficiency and longevity for 24/7 outdoor perimeter security lighting applications?
Answer: LED
LED lighting offers the best combination of energy efficiency, long lifespan (50,000+ hours), instant-on capability, and consistent light output for continuous outdoor security applications.
A security consultant is asked to recommend a camera for monitoring a loading dock where license plates must be clearly readable at night. Which camera technology is MOST appropriate?
Answer: Infrared-illuminated fixed camera with narrow field of view
An IR-illuminated fixed camera with a narrow field of view provides the focused, high-detail nighttime image resolution required to capture legible license plate numbers at the dock entrance.
The concept of 'security-in-depth' applied to surveillance means:
Answer: Layering multiple overlapping detection and monitoring systems so no single point of failure defeats all coverage
Security-in-depth uses multiple overlapping layers of surveillance and detection so that defeating one system still leaves others in place to detect, delay, or respond to a threat.
A video analytics system is generating an excessive number of false alarms due to tree branches moving in wind. Which setting adjustment is MOST appropriate to reduce nuisance alarms without disabling motion detection?
Answer: Define an exclusion zone around the trees in the analytics software
Drawing an exclusion (or masking) zone over areas known to cause false triggers—like swaying vegetation—tells the analytics software to ignore motion in those specific regions while still detecting motion elsewhere.
