The invention relates to an anti-intrusion surveillance system employed to survey and protect closed or semi-closed spaces against intruders. According to the invention, the system consists of a monitoring and protection subsystem (A) mounted in the access areas of the site to be monitored and a mobile remote control subsystem (B) which controls the monitoring subsystem (A), where the monitoring subsystem (A) comprises the following components: a presence sensor (1) meant to detect the persons entering the access areas of the site to be monitored, a device (2) meant to spray an irritating solution/gas, a video camera (5) for recording/taking photographs of the event, and a transmission antenna (6) which transmits the event to the control subsystem (B), all the said devices being mounted within a metal casing (7) located in the zone of the access doors/windows of the monitored area in which there are, as well: a voltage source (8) for supply from the mains and a spare secondary battery (9), a control receiver (13) meant to receive the enabling/disabling commands transmitted by the control subsystem (B), by means of a receiving antenna (14), a delay block (15) which receives the signal taken over and processed by a receiver (13), an intermediate relay (16) and a solenoid (17) which is actuated by the intermediate relay (16) and which, in its turn, actuates the spraying device (2), and a transmitter (18) having the role to transmit, by microwaves, the video images from the video camera (5) and the sound taken over from a microphone (19), through the transmission antenna (6), where the control subsystem (B) consists of a plastic body (20) containing an enabling/disabling switch (21), a transmission antenna (22), an on/off switch (23), an electronic circuit block (24) and a receiving block (25). |
