Many smart home security systems today can detect break-ins but don't actively prevent them, creating a gap in home protection. When burglars use power tools to break in, there's currently no automated way to cut power to these tools while keeping essential systems like security cameras running. This leaves homes vulnerable even when alarms sound.

A smarter approach to home security

One way to enhance home security could be by creating a system that automatically manages power during break-ins. When sensors detect unauthorized entry, this system could selectively cut power to exterior outlets (where power tools might be plugged in) while maintaining electricity to critical systems like alarms and emergency lighting. Homeowners could override the system remotely if needed, and all power events would be logged for review.

The system might work by installing smart circuit breakers or relay modules that connect to a central hub. This hub would communicate with existing smart home devices through standard APIs. For example:

• When window sensors and motion detectors both trigger, the system could cut power to outdoor outlets
• Essential circuits like security cameras and phone lines would remain active through battery backups

Potential benefits and applications

This approach could particularly help:

• Homes in high-crime areas needing extra protection
• Vacation properties where owners can't respond quickly to alarms
• Households with valuable collections requiring enhanced security

Implementation considerations

Starting small with off-the-shelf smart relays and existing alarm system APIs could help test the concept. Early versions might focus on basic functionality like cutting power to pre-designated outlets when alarms trigger. More advanced versions could include machine learning to reduce false alarms by analyzing usage patterns. Key challenges would include ensuring the system doesn't accidentally cut power to essential devices and preventing burglars from disabling the whole system by cutting the main power.

Unlike traditional alarms that only notify homeowners or whole-home surge protectors that cut all power, this approach would offer targeted power management specifically for security purposes. It could fill an important gap between passive alarms and more extreme security measures.
