THE UNIVERSITY CIRCLE POLICE DEPARTMENT USES CLOSED CIRCUIT TELEVISION WITH LASER BEAM TRANSMISSION TO KEEP THE CULTURAL-EDUCATIONAL COMPLEX OF CLEVELAND, OHIO UNDER CONSTANT 24-HOUR SURVEILLANCE.
Abstract
THE JURISDICTION OF THIS SPECIAL POLICE DEPARTMENT ENCOMPASSES MUSEUMS, HOSPITALS, AND UNIVERSITY CAMPUSES LOCATED WITHIN A TWO SQUARE MILE AREA CALLED UNIVERSITY CIRCLE. THERE ARE PRACTICALLY NO PRIVATE RESIDENCES AND THE AREA IS ADJACENT TO SEVERAL HIGH-CRIME AREAS. TWO CLOSED CIRCUIT TELEVISION SYSTEMS WERE PURCHASED AND INSTALLED WITH MONITORS INSIDE THE POLICE STATION. THERE ARE MANY ADVANTAGES OF LASER BEAM TRANSMISSION OVER THE CABLE NETWORK NECESSARY FOR CONVENTIONAL TV SURVEILLANCE SYSTEMS. THE CAMERAS NEED NOT BE PERMANENTLY LOCATED. THIS FEATURE LENDS BOTH PORTABILITY AND FLEXIBILITY TO THE SYSTEM. THERE IS NO NEED TO REROUTE CABLES OR OVERHEAD WIRES WITH CHANGING OBJECTIVES, ONLY THE LASER BEAM NEED BE REDIRECTED FOR RELOCATION. THE CAMERAS ARE IN OPERATION 24 HOURS PER DAY IN ALL BUT THE MOST SEVERE WEATHER CONDITIONS. INTERFERENCE FROM ELECTROMAGNETIC SOURCES DOES NOT AFFECT THE SYSTEM. (AUTHOR ABSTRACT MODIFIED)
