CCTV coverage and blind spot analyses

Identifies substantive CCTV coverage, camera-placement, surveillance-map, and blind-spot analyses. Topic phrases are retained for discovery; enforcement requires site/camera analysis detail, and high confidence requires both a precise site asset and an identified coverage weakness.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence requires an analysed camera or site element. High confidence additionally requires an explicit weakness, so procurement brochures and general surveillance policy do not reach the operational tier.
Detection quality: Topic false positive
Jurisdictions: global
Regulations: GDPR
Data categories: location, security
Scope: wide
Risk rating: 8
Platform compatibility: Purview: Compatible, GCP DLP: Compatible, Macie: Compatible, Zscaler: Compatible, Palo Alto: Degraded, Netskope: Unsupported

Should match

CCTV coverage analysis — Low-tier probe - topic without site or camera detail
Camera placement plan for the loading dock and east entrance, camera CAM-12, field of view 78 degrees — Medium-tier probe - precise camera and site analysis without a stated weakness
Blind spot analysis: CAM-12 at the loading dock leaves a dead zone behind Gate 3 with no coverage — High-tier probe - precise asset/site reference and explicit coverage weakness

Should not match

unrelated generic text without domain phrases — No relevant topic phrases present
placeholder value 12345 — Random text should not match topic-specific regex
cctv blind spot — Generic word pair from old broad template should not match
The procurement policy requires security cameras at all new offices. — Generic policy requirement, not a coverage analysis
Training example: CAM-12 loading dock blind spot and no coverage behind Gate 3 — Explicit training content must not enforce

Known false positives

Camera brochures, installation guidance, and physical-security policies discuss placement and fields of view without revealing a real site's coverage. Mitigation: Require a camera, zone, floor-plan, entrance, perimeter, or other site-analysis element before enforcement.
Training maps can include realistic camera IDs, gates, blind spots, and no-coverage findings. Mitigation: Reject explicit template, demo, tutorial, sample-data, and training-example framing from enforcing tiers.
