- Security is the major concern in our day-to-day life for our convenience and safety purpose. Everyone wants to be much as secure as possible because of the drastic increase crime rate due to increasing unemployment or starvation in corona epidemic. In this review paper, we had tried to increase the standards by combining new design techniques and developed low-cost home and industrial automated security systems. Lot of research been carried out deploying sensors like PIR, sensor, camera, GSM modules towards detecting the intruder at home. But the major drawback in all these systems is that they are all too much costly to be deployed integrated with LCD panel or camera. As a part of our review paper, we have developed an integrated 3 level HSS. The first level being authentication access for the residents, where in we have used a fingerprint scanner. The next level in our HSS is to detect any unwanted intruder entering the house. The 3rd level is to detect fire in the house.
