Patent ID: 6885301

Claim:
A security system for detecting external intrusions at individual windows which are constructed in numbers in a building and integrally processing the detected signals to thereby make alarms, the security system comprising: an intrusion detection transmission system ( 100 ) provided in each window (WD); a central processing system ( 200 ) provided in each home indoor place of the building, for integrally receiving and processing the transmission signals from the intrusion detection transmission system ( 100 ); and a remote controller transmitter ( 300 ) for generating and Tirelessly transmitting a remote controller signal for turning on or off operations of the central processing system ( 200 ), wherein said intrusion detection transmission system ( 100 ) comprises: a human body detection sensor ( 110 ) for detecting heat radiated from an external intruder reaching a window (WD); an infra-red sensor ( 120 ) having a transmitter ( 120 a ) for transmitting infra-red light and a receiver ( 120 b ) for receiving the transmitted infra-red light, both of which are installed in respective outdoor sides of the window (WD), for detecting the intruder reaching the window (WD); a switching unit ( 130 ) having a setting switch so that both a detection setting and a detection release setting are possible according to manipulation of a user, for outputting a detection signal from the human body detection sensor ( 110 ) and a detection signal from the infra-red sensor ( 120 ) during selection of the detection setting in the setting switch; and a wireless transmitter ( 140 ) for wirelessly transmitting the detection signal output from the switching unit ( 130 ), and wherein said central processing system ( 200 ) comprises: a wireless receiver ( 210 ) for receiving and demodulating the wireless transmission signals from the wireless transmitter ( 140 ) which is configured in correspondence to each window (WD) and the remote controller transmitter ( 300 ) for transmitting a user manipulation, and outputting detection signals from the sensors ( 110 and 120 ); a home switching unit ( 220 ) for connecting the outputting signal of the wireless receiver ( 210 ) to a post-end of the home switching unit ( 220 ) according to a control mode from the remote controller transmitter ( 300 ); an external connection terminal ( 230 ) for connecting the output signal from the home switching unit ( 220 ) to an external apparatus ( 400 ); and a warning siren portion ( 240 ) for generating a warning siren according to the output signal from the home switching unit ( 220 ).
