This paper presents a novel closed loop architecture for citizen security using LoRa based devices. The proposed system comprises of a custom made end-device which can be connected to street light poles in an area and a gateway device which can be connected at a large distance from the end-devices. LoRa physical layer is used as the main communication interface which enables large distance transmission. A data logging server is used for logging the node-id everytime it is pressed. Data is uploaded to the server using a 4G-LTE dongle. An android app is also developed which shows the location of the pressed node and provides navigation routes to the concerned security person to reach that node. We have compared our network operation with commercially avilable security devices. Power consumption and cost are the two metrics chosen for evaluation. Results show that our network is extremely low-cost and low-powered than existing solutions.
