In the experiment, the researcher recorded and saved video files for 48 days (The video files with different lengths of 1,2,4, and 6 minutes were all recorded for 12 days). The video files had an image resolution of 1,920 × 1,080 pixels. A CCTV camera was installed in the researcher’s office on the 1st floor of the Language and Computer Center building, Roi Et Rajabhat University. At 23.56 each day, the system uploaded the video files to the Raspberry Pi boards (server) and recorded the statistics. It was found that the whole system was practical. Warning messages could be sent via line notify when both Raspberry Pi boards could not communicate. From the efficiency measurement, it was found that NFS was more efficient in copying the files via powerline network than FTP. The larger the files, the bigger difference in copying time.</p>}, number={1}, journal={JOURNAL OF INFORMATION SCIENCE AND TECHNOLOGY}, author={Yangsila, Cheawchan}, year={2020}, month={Jun.}, pages={30–38} }
