Security Alarm for Windows & Doors Highly sensitive sensors detect even the slightest gaps or vibrations in doors and windows. This security alarm detects intruders early and deters them with a 130dB alarm (equivalent to the maximum volume of a jet taking off), alerting those nearby to the unusual situation. Installation is simple, just attach with the included tape. Alarm volume can be adjusted to 3 levels. Can be installed not only on windows and doors, but also on showcases and other places that open and close.
