There is no info on the exact cam location, but by the look of it, it should be somewhere 25-30 km to the NE of Vatnajokull, looking over the flat sandy plain between Bardarbunga and Askja.
Edit: managed to find the location (approximately 64°58'33"N 16°29'25"W):
Another webcam has been put up overlooking Bįršabunga volcano. The new one is situated on Vašalda peak in the central highlands, just north of Vatnajökull glacier.
The distance to Bįršarbunga is approximately 60 km (37 mi).
