Product Overview

The Kedacom Maintenance Switch is an intelligent recognitive IP camera designed for lane-based vehicle monitoring. It detects, tracks and captures vehicles as they move through a marked lane, then reads and logs the license plate automatically — no manual review required for routine traffic.

The switch uses status LEDs to indicate SYSTEM ARMED and SYSTEM INACTIVE conditions. When the key is turned toward SYSTEM INACTIVE, the inactive indicator illuminates and the armed indicator turns off. The manufacturer listing states that the key can be removed in the SYSTEM ARMED position.

Typical applications

  • Fire alarm system maintenance operations
  • Fire suppression / extinguishing system maintenance
  • Inspection, testing and servicing periods
  • Authorized isolation of actuation circuits
