ADT Adds Free Alert Feature for Abnormal Home Activity

ADT introduces a new alert system that detects deviations in daily routines using existing sensors. The feature costs nothing for eligible subscribers.
Key points
- ADT+ customers get Unusual Activity Alerts for free if they have a V5 Base and compatible sensors.
- The system requires 14 days of data to learn patterns and ignores activity older than 60 days.
- No video or audio is used; alerts are based only on data from door, lock, or garage sensors.
ADT has rolled out a new feature called Unusual Activity Alerts for its ADT+ subscribers. This tool monitors connected home devices to spot changes in normal behavior.
The system learns your daily patterns over two weeks. It then sends a phone notification if an event breaks the usual routine. This allows you to check if something is wrong.
How the pattern learning works
The feature relies on data from specific hardware. You need a V5 Base or newer paired with certain sensors. These include door sensors, smart locks, or garage controllers.
The system collects data for at least 14 days. It ignores any activity older than 60 days. Factors like the day of the week and season influence the patterns.
Privacy and data usage limits
ADT states that no video or audio is used for this feature. It relies solely on sensor data from connected devices. This approach is designed to protect user privacy.
Users can provide feedback on each alert via the app. A thumbs up or down helps improve the system's accuracy over time. This feedback loop refines what counts as unusual.
Cost and availability details
This feature is available at no extra cost for ADT+ customers. It works for both professionally installed and DIY systems. However, it requires specific compatible hardware to function.
You can turn this feature off in the app's menu. ADT clarifies that this is not a replacement for life safety monitoring. It is a supplementary tool for routine awareness.
