Reviewing false alarms before expanding a system

A gate that alarms often can make staff ignore the signal and make customers uncomfortable.

A gate that alarms often can lead staff to ignore the signal and make customers uncomfortable. Before adding the same equipment to more stores, review the causes of false or unverified alarms.

Create an alarm log

Log the time, entrance, tag type if known, checkout status, staff observation and outcome. Classify each as a confirmed loss, a missed tag deactivation, a system fault or an unresolved alarm. An alarm count alone tells you little about loss: some incidents are never detected, and some alarms involve no loss.

Compare alarm rates across exits and trading periods, adjusting for customer traffic if available. Check the deactivation workflow, nearby tagged stock, sensor placement and maintenance history. Where EAS, RFID and video are combined, verify what each signal captured rather than trusting the dashboard to identify a person or item correctly.

Alarm Classification and Impact on Store Operations

Confirmed Loss
Actual theft detected by alarm and verified by staff or video
Missed Tag Deactivation
Item leaves without proper deactivation at checkout, triggering alarm
System Fault
False alarm due to equipment malfunction or sensor misalignment
Unresolved Alarm
Alarm triggered but not verified or acted upon within standard timeframe

Key Metrics to Track When Evaluating Alarm Reliability

Total Alarms (Monthly)
Not specified – requires internal tracking
Confirmed Loss Incidents
Track percentage of alarms that result in actual loss detection
Customer Complaints Related to Alarms
Reported discomfort or frustration during alarm events

Change one thing and retest

Pilot a fix in one area—checkout training, tag placement or equipment service. Keep the baseline, then review the same measures: confirmed incidents, unverified alarms, staff time and customer complaints. If the system uses recordings, follow the store's privacy controls and applicable law. Expand only when the signal is reliable enough for staff to respond consistently and respectfully.
