The PipeScope Compatibility Matrix provides an objective, specification-driven framework for determining whether a sewer inspection camera, locator receiver, or monitor can safely and effectively perform in specific pipe diameters, materials, and jobsite scenarios.
Evaluation Engine Status Definitions
Every equipment pairing in our matrix is evaluated against verified manufacturer documentation and assigned one of five standardized statuses:
- VERIFIED_RANGE: The manufacturer explicitly documents this specific pipe diameter or accessory combination in official engineering documentation, with confirmed geometric clearances.
- SPEC_SUPPORTED: The equipment dimensions and frequency profiles align mathematically with the pipe geometry, even if the OEM documentation does not explicitly list every individual pipe material.
- CONDITIONAL: The equipment can operate within this diameter only under specific constraints (e.g., straight runs only, smooth PVC pipe, or requiring centering skids to prevent camera submersion).
- NOT_RECOMMENDED: Documented engineering dimensions indicate high risk of binding, insufficient illumination, or frequency mismatch.
- DATA_INCOMPLETE: Essential manufacturer engineering data is unstated, preventing mathematical verification.
The “No Upgrade” Rule and Evidence Hierarchy
PipeScope Lab adheres to a strict “no upgrade” policy: unverified marketing claims, promotional YouTube reviews, or user forum anecdotes are never used to upgrade a product’s status from DATA_INCOMPLETE or CONDITIONAL to VERIFIED_RANGE. Only official OEM documentation, first-party technical drawings, or certified lab specifications provide grounds for verified status.
Applying Matrix Results to Real-World Pipe Surveys
When selecting equipment for commercial or residential inspection contracts, always review the specific limitations associated with each matrix cell. For example, a camera rated as CONDITIONAL for 6-inch clay pipe may require heavy-duty centering skids to lift the lens above standing sludge and root masses. Understanding these parameters ensures accurate diagnostic reporting and protects push cables from excessive drag.
Cross-Checking Receiver and Sonde Frequencies
In addition to physical pipe fit, the compatibility matrix evaluates electromagnetic frequency alignment between camera sondes and locator receivers. A camera with an embedded 512 Hz transmitter will register as incompatible with receivers limited to 33 kHz or 640 Hz. Always ensure both physical clearance and frequency match before purchasing.
