Description

Technical Field

[0001] The utility model belongs to the technical field of alarms, in particular to a two-in-one dual-sensing door and window alarm. Background Art

[0002] Door and window alarms are devices that sound an alarm when doors and windows are not closed properly or are opened by prying. They can effectively prevent theft and bring great convenience to people's lives.

[0003] Most door and window alarms currently on the market are single-function, relying primarily on vibration sensors or magnetic switches. However, in many cases, relying solely on a single sensing method fails to fully address potential safety hazards, and there's no effective way to analyze and eliminate false alarms caused by minor vibrations caused by wind and rain. For example, if an attacker only vibrates and damages a door or window without moving it, the alarm won't trigger in time when using a magnetic switch. Relying solely on vibration sensors, on the other hand, can be affected by external factors like ambient noise, leading to false alarms. Both types of products have their limitations, requiring users to configure additional sensing devices, increasing costs and complexity, and warranting further improvement. Utility Model Content
