The PV12A flat-panel computing device is a fully functional computer of a monoblock design, with a 12" screen. The product is equipped with a touchscreen and a stereo sound reproduction system; it can be connected to a protected webcamera for arranging video conference calls. Headphone and microphone connecting outlets on the front panel may be used to connect a stereo headset. 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. The flat-panel computing device can be installed on fixed or vibrounloaded supports, or on a RVR-like vibrounloaded frame, or integrated into a control panel or other consumer's equipment.
