The vibration sensor detects the vibration condition of the case 1, and when the vibration is greater than a preset threshold (for example, vibration displacement is greater than 10mm or vibration speed is greater than 5 m/s), the case 1 is in an abnormal state, and can be violently damaged by someone, or the case 1 is likely to be impacted accidentally, and then the case 1 needs to be started for video recording. The displacement sensor detects the displacement of the case 1, and when the displacement is larger than a preset distance value (larger than 1 m), video recording is started. In order to further control the safety of the case 1, not only the theft is dealt with, but also a temperature sensor can be arranged to detect the temperature condition in the case 1, when the temperature is greater than a preset temperature threshold (for example, 60 degrees), the case may be that an internal circuit fires, or an external person is baked with fire, and at this time, the case may be started to record video.
