A system for visual surveillance and documentation of an event or events including one or more cameras to visually record the event, and a monitoring member or transducer to derive information regarding the event. The visual representation of the event is contained in a video signal, whereas the information is contained in an information signal. A conversion device operates on the information signal to convert it into a format which is integratable with the video signal. The video and information signals are then combined or integrated into a combining device which outputs a third composite signal containing both the visual recording and the information. The third signal can then be recorded, displayed, or otherwise utilized to document the event, and neither the visual or information portions can be independently altered, thereby increasing validity and reliability of the documentation.
