Compare Monitoring Architectures and Costs

Use these comparisons before a request for proposal, pilot or architecture decision. They deliberately avoid vendor rankings because suitability depends on site distribution, operator coverage, maintainability, data needs and response workflow. Score evidence rather than marketing claims: installed reference checks, forced outage recovery, data export, device identity, update controls, field-service intervals and end-to-end alert tests. Lifecycle cost should keep site visits, connectivity, gateways, calibration, replacement and operations visible as separate variables. If one uncertain assumption can reverse the preferred option, make that uncertainty a pilot objective rather than hiding it in an average.
