The choice between wireless and wired sensors is less about technology preference and more about the asset, the building and the consequences of a lost signal.

What matters more than the connection

  • Buffering: does the sensor or monitoring station store data when the link drops?
  • Fault detection: is a lost signal raised as a technical alarm?
  • Continuity: is there battery support and an alternative network path?
  • Calibration: can the sensor be calibrated in its working range?

Why most sites use both

A hybrid design uses wired connections where reliability is critical and wireless where flexibility helps. What matters is that all sensors end up in one record, with the same alarm logic and evidence.

How XiltriX Resilience fits

XiltriX Resilience is an Operational Resilience System built on three layers:
  • Infrastructure: independent sensors and monitoring stations with battery support, resilient connectivity and local data buffering, so a power or network interruption does not create a gap in the record.
  • Intelligence: validated software that turns measurements into alarms, escalation, trends, reports and audit-ready evidence.
  • Care: installation, validation, calibration, preventive maintenance and 24/7 technical support for the monitoring system, delivered by one partner that is ISO 9001 and ISO 27001 certified.
