Tamper Detection Shootout - Avigilon, Axis, Dahua, Hanwha, Hikvision, and Uniview

By Rob Kilpatrick, Published Feb 22, 2021, 09:09am EST (Info+)

IP cameras have claimed to detect tampering for years, but how well do they really work?

IPVM Image

To find out, we tested tamper detection on six manufacturers: Avigilon, Axis, Dahua, Hanwha, Hikvision, and Uniview. Inside, we examine:

  • The critical false nuisance alert issue all manufacturers suffer from
  • How well does tamper detection detects lenses being covered?
  • How much of the field of view must be covered to trigger alerts?
  • Do cameras alert on sudden field of view changes?
  • Does tampering detection shaking, fogging, or liquid droplets?
  • Do tampering alerts integrate to common VMSes?
