摘要： A method and apparatus by which surveillance can be maintained over a domain for detecting changes of interest in the domain and ignoring other changes. A parameter of the domain under surveillance is scanned resulting in an electrical signal which is sampled. The resulting sample signals each correspond to an individual sample point or line segment in the domain under surveillance and are digitized. Digitized samples are stored in a memory unit. An arithmetic unit based on a Karnaugh mapping technique compares to current sample with a prior sample from the memory unit for the same sample point or segment in the domain and provides an alert signal when these differ by more than a predetermined amount. A plurality of scanning devices may be provided to a monitor. If an alert occurs, an intrusion logic unit determines if an alert signal previously occurred during a prior scanning period for the same scanning device and if so an alarm is actuated and the monitor is switched to display the signal from that scanning device.

摘要： A method and apparatus is disclosed by which surveillance may be maintained over a domain for detecting changes of interest in the domain and ignoring other changes. A parameter of the domain observed is scanned and sampled. The resulting sample data for individual sample points is digitized and used to update corresponding data averages over prior scans of the same sample points. Specified differences between the sample data and data average for a sample point result in modification of a suspicion value. Correlations in space and time of sample points having particular data changes further modifies the suspicion value. An output, such as an alarm, results from ultimate attainment of a predetermined suspicion value.
