This paper proposed a LoRa-based video data transmission system for real-time monitoring in a pig farm. This approach eliminates the need for complex and costly infrastructure, making it a cost-effective solution for real-time monitoring in pig farm. The system architecture included the Raspberry Pi 4B microcontroller, RGB cameras, LoRa transceivers, gateway, and cloud-based platform for data analysis and visualization. The video data was captured using the RGB cameras and stored into an external memory through the microcontroller. Then the video was segmented into small chunks and compressed as an H.265 codec, which reduced the size of the video data and made it easier to transmit using the LoRa. Each compressed video chunk was then sent by the LoRa transceiver with a low data rate and a low transmit power. This allows the transmission to reach long distances, while consuming very low power levels. At the receiving end, the video chunks were received by another LoRa transceiver and re-assembled into the original video stream. The system performance was evaluated through a series of tests, including transmission range, video quality, and power consumption. The results showed that the LoRa-based system could transmit video data over a long range (2 km) with low power consumption (less than 1 W), while maintaining good video quality (720p resolution). The findings showed a great potential for real-time monitoring in pig farms, providing valuable insights into the pigs behavior, health, and productivity.
