Security cameras and motion detectors used for home security can be expensive and may not cover the entirety of a home or property. Also, even when an intruder is detected by the camera, there is not much that can be done after the intruder leaves. This disclosure describes the use of in-home smart devices to detect unrecognized devices via Bluetooth and automatically detect an intrusion based on such detection. The described techniques can detect intruders and can also help locate the intruders after they leave the home. The techniques can improve home security without requiring additional hardware.
