1. A method of monitoring a region for movement comprising the steps of:
- (a) monitoring the signal strength of a wireless network using a wireless network detection device to provide signal strength measurements;
(b) evaluating the signal strength measurements for changes; and
(c) determining if changes in the signal strength measurements represent movement requiring a response, and in response thereto, generating and sending response signals.

Abstract
Security systems, methods, and devices for monitoring a region for movement utilize a wireless network detector having a directional antenna and a transmitter for transmitting the detected wireless network signal strength to a computer. Analysis of changes in the signal strength measurements determines the presence of movement requiring a response.
