Anti-shielding security and protection monitoring device based on photoresistor principle

Abstract

The invention relates to the technical field of security and protection monitoring, and discloses an anti-shielding security and protection monitoring device based on a photoresistor principle. A cover plate is movably mounted at the top end of a body, and a connecting rod is fixedly connected to the right end of the body. According to the anti-shielding security and protection monitoring device based on a photoresistor principle, a photoresistor in a gravity pressing block is in a dark environment; according to the principle of photoresistance, t the higher the illumination, the lower the resistance, the lower the illumination, and the higher the resistance; the resistance is increased to be close to insulation; consequently, an electromagnetic induction coil loses magnetism, a non-magnetic iron disc cannot be continuously adsorbed; a first actuating rod inclines towards the middle and forms a certain deviation angle, and then a metal part, an opening and closing door, a second actuating rod and a push rod are used in cooperation, so that the anti-shielding security and protection monitoring device has the anti-shielding function, the anti-theft performance is improved, the loss rate of people is reduced, and the problem that a traditional security monitoring camera is not provided with any prevention device is solved.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to an anti-blocking security monitoring based on the principle of a photosensitive resistor. Background technique [0002] The current residential quarters are mostly high-rise buildings. Due to the dense population, if a fire breaks out, it will inevitably cause severe casualties and property losses. Therefore, safety protection is increasingly emphasizing fire prevention and the popularization and application of safety technologies. Among them, security monitoring plays a role in preventing and checking the safety situation. At present, security monitoring has become an indispensable device, providing a strong guarantee for our safety. [0003] However, in real life, criminals usually cover the security surveillance cameras outside the community before committing crimes, resulting in the security surveillance cameras not being able to record more information about the ...
