Door Alarm System that Monitors an Open Door for Intrusions

Background

There has been a recent rise in the number of people impersonating delivery workers, and is partially due to home alarms only being sold to secure closed doors. By analyzing the interaction between homeowners and burglars, it was apparent burglars can exploit this flaw by assuming a fake identity to persuade homeowners to disable their alarm system. The need for an additional layer of safety to existing home alarm systems could be addressed with sensors to monitor open doors for the purpose of protecting homeowners and their property from people impersonating delivery workers.

Invention Description

Researchers at Arizona State University have developed a novel door alarm system that uses sensors to monitor an open door in order to protect homeowners and their property from people impersonating delivery workers to break into homes, by monitoring the status of the open door. Instead of disarming the entire home alarm system to open the door, the homeowner will use the keypad to re-arm the front door allowing other sensors to monitor the door opening. If the door opens too far, the alarm is triggered. By allowing homeowners to open their door while keeping their security system active, homeowners will be protected from fake deliveries.

Potential Applications:

  • Crime prevention and security
  • Visitor and delivery verification system
  • Home automation and smart devices

Benefits and Advantages:

  • User-friendly
  • Security system remains active even with an open door
  • Control pad designed around a keypad with a custom pin
