The PV15VA flat-panel computing device is a fully functional computer of a monoblock design, with a 15" screen. Since this computing device is intended for full-capacity operation in fully or partially flooded rooms, the use of a touchscreen is inexpedient. The computing device is framed with action buttons from a standard keyboard set which are needed to operate customer's software. The "Day/Night" mode is available and used in case of insufficient visibility. Structurally, the device is designed as a protected system enclosed in an aluminum alloy casing. This design allows the product to be operated under severe conditions: in premises, in car bodies of wheel-based and track-based vehicles, at fixed and mobile onshore and offshore facilities. Upon the customer's request and dependent on the motherboard capabilities, the PV15VA flat-panel computing device can be equipped with interface connectors.
