However, the existing sentry mode has the remarkable limitation that the core function is mainly based on passive video recording and post warning, a means for actively warning surrounding environment is lacking, and possible scratch and damage are difficult to actively avoid. Specifically, the existing sentry mode mainly depends on two means of camera recording and acousto-optic prompting. The camera recording scheme can only realize post-retrospection and cannot actively interfere when threat occurs, and the acousto-optic prompting scheme (such as alarm sound and lamplight flickering) has a certain warning effect, but has the following defects that firstly, an acousto-optic signal is easy to interfere by environmental noise and light, the warning effect is unstable, secondly, frequent acousto-optic prompting is easy to cause alert fatigue of surrounding personnel, the deterrent effect is reduced, and thirdly, the acousto-optic prompting lacks a deterrent force of a physical layer, so that malicious destructive behavior is difficult to effectively prevent.
