Abstract: A security system comprises a locatable portable electronic camera image transmission unit which both identifies its own location by utilising the capabilities of an integral position location apparatus module while at the same time electronically photographing and otherwise recording the immediate scene. This combined navigational and photographic information is at the same time both stored within the locatable portable electronic camera transmission unit and transmitted, along with any other desired information such as user name, address and time of day to a distant remote receiver. The remote receiver converts the transmitted navigational information into a display of the location of the locatable portable electronic camera transmission unit upon a map, and this navigational and the other visual information is suitably displayed upon a television screen and is also presented as a hard copy on a facsimile receiver.
