Step-by-step diagnosis
Confirm the symptom
Check whether the fault is constant or intermittent and whether it affects one device or the whole system.
Check power and cabling
Verify power, polarity, PoE, battery, terminations and patching.
Check configuration
Confirm IP address, zone, reader address, relay mapping, app registration or recording settings as relevant.
