ABSTRACT:
A deployable stationary device includes a device support, rate gyros supported by the device support, the rate gyros being oriented along different axes, and a controller supported by the device support. The controller is arranged to receive rate gyro signals from the rate gyros. Each rate gyro signal indicates a rate of rotation about a respective axis associated with a particular rate gyro. The controller is further arranged to perform a vector sum operation based on the rate gyro signals, and generate a direction signal which identifies a direction resulting from performance of the vector summing operation. Such a deployable stationary device is capable of operating as one of a network of such devices in a surveillance system to enable detection and precise location of suspicious activity.
