Automatic Weather Stations (AWSs) consist of sensors that automatically collect and transmit weather data. AWS efficiency is achieved if the cases of vandalism and theft are minimized. Securing weather station equipment is a daunting task, aggravated by increase in the number of weather stations deployed in remote areas. This paper discusses the security challenges experienced by weather station implementers. It proposes and analyses a cost-effective weather station security system. Such a system is necessary to curb the high costs of maintenance that result from theft and vandalism of weather station equipment. Our proposed design of the security system is the use of surveillance cameras to surveil the weather station perimeters
