CCTV Video Recording and Storage 5

Question 1

What is the primary risk of storing all CCTV footage solely in the cloud?

Accepted Answer

Dependence on continuous internet connectivity and upload bandwidth

Answer

Cloud-only storage requires a reliable, high-bandwidth internet connection; an outage or bandwidth bottleneck will cause recording gaps.

Question 2

Which recording mode uses the least storage while still capturing security-relevant events?

Accepted Answer

Motion-triggered recording

Answer

Motion-triggered recording only saves footage when activity is detected, dramatically reducing storage use compared to continuous recording.

Question 3

What does 'forensic integrity' mean when handling CCTV recordings as evidence?

Accepted Answer

Preserving the original file unaltered and documenting the chain of custody

Answer

Forensic integrity requires that original recordings remain unmodified and that every person who accessed them is documented to ensure admissibility in court.

Question 4

A security manager wants to reduce storage costs without shortening the 30-day retention period. What is the best approach?

Accepted Answer

Lower the recording resolution and frame rate during low-activity hours

Answer

Reducing resolution and frame rate during non-peak periods lowers daily data volume, maintaining the same retention window at lower storage cost.

Question 5

What is 'intelligent video analytics' (IVA) storage, and how does it differ from raw video storage?

Accepted Answer

IVA stores only metadata and event flags rather than full video streams

Answer

IVA can store structured metadata (object types, trajectories, events) separately, allowing fast searches without replaying raw video.
