Live video streams at varying resolutions and frame rates. (video capture from screen)

We’ve used quite a few different video resolutions and a couple of frame rates. In all cases we’ve kept a constant bit rate of 200Kbps – Richard at callmonitor.com recommended this setting and it has served us well. Higher bit rates are probably possible, but we’re using a ‘Standard’ BGAN data link configuration (rather than one of the Streaming configurations) so we don’t really want to push our luck. The following two sets of clips show the performance we had for video at different camera settings. The first set show Paul in front of the camera with a flag, the second set show the points where we made the video link after changing the camera settings. In both cases the smoothness of the video relates to the camera’s frame rate and the clarify of the image relates to the camera’s resolution.
