PROBLEM TO BE SOLVED: To provide a security system, a security device and a security method, capable of securing security of a resident of coming home, when there is a possibility of a third person illegally intruding into a house. SOLUTION: This security system 1 has a controller 5 for controlling locking and unlocking of a main entrance door 4 on the basis of radiocommunication with an electronic key 3, an electric lock 6 for putting the main entrance door 4 in a locking state or an unlocking state, and an abnormality monitoring device 7 for mainly controlling the system. When a detecting sensor 8 detects illegal intrusion in a state of setting the security system 1 in a precaution mode, the abnormality monitoring device 7 photographs a scene of the illegal intrusion by a camera 9, and restricts unlocking of the electric lock 6. Thus, even if ID collation is realized between the electronic key 3 and the controller 5 when the resident comes home, since the electric lock 6 is put in a restricting state, the electric lock 6 is put in a not-locking state, and a scene picture of the illegal intrusion photographed by the camera 9, is televised by a monitor 10.
