Image-based Transmission Schema for Autonomous Wireless CCTV

Regular image transmission on Closed-Circuit Television (CCTV) systems requires good network, especially for transmitting high quality digital image. However, sending high quality digital image through limited bandwidth needs several precautions and treatments, like which image to be sent, how the image will be sent and when. Without these precautions and treatments, in return it will results in energy inefficiency. The main purpose of this research is the power supply efficiency towards high quality digital image transmission schema for autonomous CCTV. This research considers individual but consecutive images transmission rather than video transmission to limit the processing time and power. This research focuses on high quality digital image transmission from a CCTV to collector node through Narrowband Internet of Things (NB-IoT) network. To improve the lifetime of the power supply of the CCTV, this research conducts performance measurement comparing on several digital image compression and transmission algorithm to find optimal bandwidth usage to arrange which data to be sent based on several conditions. The arranged data are sent to the collector node through NB-IoT. This research provides the algorithm in choosing image for transmission to reduce bandwidth usage and power consumption.
