In earlier research, a low cost and high resolution agricultural vision sensor (HRAVS) was developed based on the platform S3C6410 and OV3640 in South China Agricultural University. In this paper, a vision sensor remote transmission control schema (VSRTC) was developed to enable HRAVS to communicate with each other in various communication technologies (cable, 3G, 4G and Wi-Fi). The combination of HRAVS and VSRTC can be applied in many areas of the Internet of Things (IOT) in Agriculture. This paper introduced design of application architecture, transmission control protocol, and the node’s application software of the VSRTC-HRAVS. A WVSN test was conducted for 25 days with 10 camera nodes i
