1, improve defence rank, more focused on the idea of putting prevention first.The symptom of a trend that much may occur can be prevented in advance.People's hand contact lockhole cap once there be the heart of crime, will send neutral warning language, immediately because this early warning also has distance from forcing open the door very much, so criminal is still had to very large deterrent effect.
2, having people to want to enter room by barbarous mode, door is separated with doorframe, and alarming starter also can promote sound system, sends warning.
3. do not affect neighbours's relation, do not injure person unintentionally, energy science is processed the relation of " having a mind to " and " being not intended to " behavior.
4, do not lose the due function of common alarm.
5, lockhole switch, does not need artificial additional move, and (as opened the door at every turn, closing involution behind the door), does not affect the normal habits and customs of people, thus do not affect the each starting of security system normal operation.
6, after the invention process; anti-theft safety door and alarm have been realized the combination of science; the advantage that has possessed two kinds of protectors; usually both people can be kept outside the door; when running into other people and committing a crime; can send two kinds of warnings; to increasing " the initiatively protectiveness " of anti-theft safety door; (its implication is; function of the present invention will suppress crime behavior generation; and whether waiting for passively that it destroys) and be all very significant, the situation of the passive defence of anti-theft safety door so this product is through with completely, has promoted security personnel's performance of anti-theft safety door all sidedly.
