Abstract
PURPOSE: To save the trouble of persons in charge of precaution by giving an alarm only when a person of enemy character intrudes while remote guard duty is carried out by making use of a TV camera.
CONSTITUTION: Change detector 4 is stored with the output of TV camera 1 at the time when precaution area 2 is normal and the output of TV camera 1 is compared with the stored contents mentioned above, so that when a difference more than the fixed allowable capacity is found, a change discrimination signal will be generated. This change discrimination signal is inputted to multiplexer circuit 7 by way of change discrimination signal transmitter 5 and information transmission line 6. Circuit 7 connects information transmission line 6 to monitor device 8 to generate an alarm. By supplying information on the specific time zone and specific point, friend information transmitter 3 controls change detector 4 not to supply the change discrimination signal to change discrimination signal transmitter 5. In this way, a change in friend action, etc., are excepted from the precaution objects and an intruder is displayed on monitor device 8 via TV camera 1.
