Both GPIO Boards provide input and output expansion for the JVA Security Management System. The 4 digital Inputs are able to monitor devices such as motion detectors, IR beams or door contacts; the 4 relay outputs can be used to turn on security lighting, sirens or even water pumps. The eGPIO has additional features in that it can connect directly to Perimeter Patrol via the onboard Ethernet/Wi-Fi connection. It also has the ability to monitor analogue devices such as temperature sensors, pressure sensors and water level indicators.
