Design and development of two levels electronic security and safety system for buildings

摘要

Today, security is not just a requirement but a necessity. It could be of any place like residences, business installations, educational institutions, etc. The paper present is on electronic security and safety system is doing bit in ridding the society of menace of burglars. In this paper initially a four digit authentic system on the door which would enable the authentic user to enter the installation. Next defence would be a trap of infrared motion detectors which on detection of any unauthorised entrance would activate an alarm which is in the hand of the owner. Thus, in the above said manner, we would be able to secure every nook and corner of the installation. The present paper is an application of electronics and communication in electrical systems. The microcontroller-based digital security system presented here is an access control system that allows only authorised persons to access a restricted area.
