The camera 6 is provided inside the main body of the lock device 33 attached to the front door 32 of the installation target device 31. The recording device is provided in a position away from the lock device 33 in the installation target device.

  In the present invention, since the camera is incorporated in the door locking device, the entire locking device can be replaced with an existing one, installation is easy, and complicated processing for the installation target device such as a vending machine is not required. . Since the captured images for a predetermined time before and after the vibration of the installation target device are recorded, it is possible to reliably record a series of destruction acts on the installation target device and the appearance of the perpetrator. Since the image is recorded only for a predetermined time before and after the vibration detection time point, unnecessary subsequent image recording is not continued, the confirmation of the image data is facilitated, and a recording device with a small recording capacity can be applied. . Since the recording device is provided in the installation target device at a position away from the lock device, the image data can be safely stored even if the camera is destroyed.
