An effective security system is designed and implemented through the application of embedded systems and the Internet of Things (IoT). The main goal of this work is to present the IoT system and modern technology systems / embedded intelligent networks. IoT is the technology of the future in contact machine / machine device / machine is possible thanks to the electronics, sensor technology, software and connectivity system to enable these items to collect and exchange data. Embedded system is a real-time mainframe structure on a particular task, an automatic or electrical system including, often within the limits of real-time raking as sensors, modules with microcontrollers, etc...This is integrated with sensor main server and GSM global system For mobile), it is able to send data and IP addresses through SMS message. This will facilitate the identification of the unknown person embedded in realtime in these devices. The video data are transferred to another back-end server via TCP (Transmission Control Protocol) of the device. This server collects data and provides HTTP Web. A browser is used to view data and can be remotely controlled. This type is giving an idea about the probability and effectiveness of the system, this thesis presents the results of the investigation into the security system and some realistic implementations.
