Abstract: In the present scenario the crimes are increasing exponentially, arising a need of security. Security can also be described as a condition so that one can develop and progress freely and with a faith that no harm may be done. Hence we are introducing any automatic door lock security system and home automation for the security purpose. Camera is now enormously being used and with the development of its content that is used in various applications. One of such is automatic door lock security system using camera.

The Internet of Things (IoT) is the interconnection of uniquely identifiable embedded computing devices within the existing Internet infrastructure. Typically, IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine- to-machine communications (M2M) and covers a variety of protocols, domains, and applications. The interconnection of these embedded devices (including smart objects), is expected to user in automation in nearly all fields, while also enabling advanced applications like a Smart Grid. Things, in the IoT, can refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters, automobiles with built-in sensors, or field operation devices that assist fire- fighters in search and rescue. Current market examples include thermostat systems and washer/dryers that utilize wifi for remote monitoring.

Interfacing of camera to capture live face images. Create a database of authorized person if they exist. Capturing current image, save it and compare with the database image. Interface GSM module to send alert to authorized person while unlocking the locked door in the form of SMS and CALL. The project can also be used for surveillance. For instance, it can capture the images of unidentified individuals and store it which can later be used to determine the impostors who tried to gain illegitimate access. Interface relay as on output. And additional home automation system is used to control the home appliance like fan and light using mobile application. With help of Wi-Fi connected for the model using TCP/IP.
