Cctv Coverage Pixel Storage Package

Calculates source-bound CCTV coverage metrics from a deterministic SSC-13 task-owned source pack. The template combines camera coverage, target PPM, recording retention, bandwidth, PoE, and fibre link margin.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

easy:
All source-pack values given for the SSC-13 CCTV package
medium:
All source-pack values given for the SSC-13 CCTV package
hard:
All source-pack values given for the SSC-13 CCTV package
