Security has become an important factor. Intruders have become prominent factors for all the data/property theft. The basic idea in this paper is to identify the intruder and alert owner/administrator in different possible ways. This paper discusses different ways such as “a message (SMS)”, “WhatsApp message”, “location of intruder”, “an immediate call”, and “intruder’s image to owner’s/administrator’s WhatsApp” to alert owner/administrator. For identifying the intruder, machine learning algorithm is used. A camera placed at the locality is trained such that it can identify the familiar people and it is “on” all the time. Whenever an unknown/unidentified person comes to the vicinity of the camera, all the above-said features get activated and the owner gets alerted. The idea can be applied in many real-life situations, like thief identification near the house.
