CCTV coverage and blind spot analyses

Detects CCTV coverage and blind-spot analyses: CCTV survey or blind-spot wording with populated camera records (IDs, NVR channels, locations, FOV) and located coverage weaknesses. Topic wording alone is discovery-only.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: the topic phrase alone is discovery-only; enforcement needs populated structure (a populated camera field (camera ID/number, NVR/DVR channel, location, mounting height, lens, FOV, PTZ preset, resolution, retention) or a located coverage weakness (blind spot/coverage gap/dead zone/unmonitored near a gate, door, dock, stairwell, car park, perimeter, plant or server room)), and 85 needs two distinct structures plus independent physical-security (guards, patrols, lighting, access control, intrusion) evidence, so policies, blank forms and training text stay below 75.
Detection quality: Topic false positive

Should match

The CCTV audit for the depot is due in the next quarter. — Discovery probe (65)
CCTV camera schedule - Depot Camera ID: CAM-12 Location: loading dock east — Medium-tier probe (75) - populated camera fields
CCTV coverage review - Wharf Street depot Camera ID: CAM-12, NVR channel: 7, Location: loading dock east, FOV: 78 degrees Camera ID: CAM-14, Location: north stairwell Blind spot behind Gate 3 and no coverage in the plant room; security guard patrol route and lighting do not compensate after hours. — High-tier probe (85) - several camera fields, located weaknesses and physical-security context

Should not match

unrelated generic text — No relevant phrase context
placeholder value 12345 — Random text should not match
Policy statement: the procurement policy requires CCTV coverage of all public entrances. — Policy text
CCTV camera schedule template Camera ID: ________ Location: [insert] — Blank template
Course module 2: a blind spot analysis finds coverage gaps near the gate and assigns camera IDs such as CAM-01. — Training framing
cctv blind spot — Generic word pair

Known false positives

CCTV procurement specifications and vendor brochures describe FOV and resolution. Mitigation: Guidance/template framing is excluded; 85 needs camera records plus a located weakness and physical-security context.
