Based on the technology development nowadays, we are producing terminal devices according to IoT specifications (low power consumption, lightweight, small, simple and reliable) with high computing power - like complex computing systems - allowing us to use them in complex applications. One of the sectors that demands cooperation of all system peripherals and have high impact - and many implementations - on people is area/home security. Till now, there was a separated security system in each area and in case of invasion only a central audit service was informed. Furthermore, the first implementations had only control sensors placed in crucial spots of the area and the information of invasion was only in local area (e.g. sirens). Moreover, all the systems interconnected through telephone lines (POTS, GSM) to the control center so that the authorities/owner get informed in case of invasion. More recently implementations have cameras, so that the owner can watch/record (locally) the area. In the context of this study, an innovative complex security system has been created to cover a wide area according to the needs of the control center (e.g. municipality, neighborhood) which has all the internal alarm peripherals (cameras, PIR) interconnected with external ones (moving cameras at the street level) while having centralized control (server, cloud) by using IoT devices and protocols thus minimizing the use of resources (energy, bandwidth).
