A security consultant is assessing a facility where adversaries have previously tampered with outdoor cameras. Which feature SHOULD be specified to detect physical tampering?
Answer: Tamper detection alarms integrated in the camera's video analytics
Tamper detection analytics automatically trigger an alert when a camera is covered, repositioned, or spray-painted, enabling rapid response before a scene is compromised.
In a large-scale surveillance deployment, what is the PRIMARY benefit of using Power over Ethernet (PoE) for IP cameras?
Answer: A single Ethernet cable delivers both data and electrical power, simplifying installation
PoE transmits electrical power along with data over a single Ethernet cable, eliminating the need for separate power runs to each camera location and reducing installation cost.
What is the MOST critical consideration when integrating facial recognition into a public-space surveillance system in the US?
Answer: Compliance with applicable state biometric privacy laws such as Illinois BIPA
Several US states have enacted biometric privacy laws (notably Illinois BIPA) that impose strict consent, storage, and data-sharing requirements on facial recognition systems.
What is 'video latency' in a surveillance system and why does it matter for live monitoring?
Answer: The delay between a real-world event and its display on the operator's monitor
High latency means operators see events seconds after they occur, which can impair real-time response to security incidents requiring immediate action.
Which network segmentation practice BEST protects a surveillance system from compromise via the corporate IT network?
Answer: Isolating surveillance cameras on a dedicated VLAN with strict firewall rules controlling access
A dedicated camera VLAN with restrictive firewall rules prevents lateral movement from a compromised workstation to the surveillance infrastructure and vice versa.
A client requests a surveillance system that can automatically count people entering and exiting a facility. Which technology MOST directly fulfills this requirement?
Answer: Video analytics with bi-directional people-counting algorithms
Bi-directional people-counting video analytics uses crossing-line detection to automatically increment entry and exit counts in real time without manual operator involvement.
When a security consultant conducts a post-incident forensic review of surveillance footage, which chain-of-custody practice is MOST important?
Answer: Documenting who accessed or copied the footage, when, and for what purpose
Maintaining a documented chain of custody — including access logs for every person who touched the evidence — is essential to preserve the footage's admissibility in legal proceedings.
