HMI gives paws for thought
3 Dec 2009
Cologne, Germany – Padded protective gloves are no obstacle at all when operating HMI stations for CCTV systems in hazardous areas, provided they run R. STAHL’s ISview video software, according to the company. Even for well-padded fingers, it claims, can accurately hit the large touch buttons on the screen for direct access to cameras.
As an alternative, operators can also use a mouse, trackball, or joystick to select cameras and work their PTZ functions. With ISview, a monitor can display live signals of up to 12 image sources as a multiple-quad view or as single views to be switched between, in window or full screen mode. In addition to IP cameras, video servers can also be incorporated, said R Stahl.
ISview displays moving images with up to 25 frames per second. With a maximum delay of 120 ms, the image signals of all connected devices reach the HMI screen almost in real time. The VAPIX-API-based software is licensed for each connected camera so that overall cost corresponds exactly to the actual size of the CCTV system.
