Amplifying risk in retail stores – KEY FACTS

• Visible security deters opportunistic thieves, but rarely stops professional offenders
• Replacing visible tags with hidden tags increased shrink by 251%
• Safer cases cut shrink by 53% and increase sales
• CCTV reduces losses initially, but effects often disappear within six months
• Targeted CCTV reduced shrink by up to 57% in trials
• False alarms undermine deterrence, with up to 93% proving false

Opportunistic thieves are deterred, professionals are not

Our research shows a clear divide between offender types. Opportunistic shop thieves are far more likely to be deterred by visible security cues than professional offenders.

By contrast, 55% of experienced shoplifters report they are never deterred by Electronic Article Surveillance, and only 2% of apprehended offenders say tagging would stop them.

Risk amplification works best against casual, low-commitment theft, but not organised or habitual offenders.

Hidden tags can make shrink worse, not better

Visibility matters. In a large multi-store trial, replacing visible hard tags with hidden soft tags caused shrinkage to rise by 251%, and remain 53% higher than control stores.

When visible tags were reintroduced, losses fell back below control levels within six months. Removing visible deterrents didn’t reduce theft. Instead, it amplified risk.

Safer cases cut shrink by over 50% and boost sales

In a randomised controlled trial, stores using safer (keeper) cases saw 53% lower shrinkage and 69% higher sales compared with control stores.

The investment paid back within three years, making safer cases one of the most effective loss-reduction interventions reviewed in the report.

CCTV works, but its impact fades fast

CCTV can reduce losses initially, but its deterrent effect often disappears within six months as offenders adapt.

In one UK study, shrink fell after 13 weeks, but returned to previous levels by 26 weeks.

Without reinforcement or variation, surveillance quickly becomes part of the background.

Targeted CCTV reduced shrink by up to 57%

In focused aisle-level trials, CCTV delivered strong results. Dome cameras reduced shrink by 27%, while public view monitors cut losses by 57% compared with control stores.

However, sales did not increase. This reinforces CCTV’s role as a loss-prevention tool, not a sales driver.

False alarms destroy deterrence

Alarm credibility is critical. One study found 93% of Electronic Article Surveillance alarms were false, while another recorded 3,732 alarms without a single theft detected.

High false-alarm rates undermine perceived risk, weaken staff response, and reduce deterrence for offenders.
