eQuest solves the problem of free integration of network and devices in each facility by the possibility of connecting of components in simple or more complex monitoring structures. Free integration is possible through taking over of operation of the lowest layers of protocols by the software located on the server. eQuest completely eliminates the need to install specialized intermediary devices (logic gates, converters or programmable routers for different facility-oriented protocols). There is only need to adjust electrical standards to each other.
