Once ia have that problem with GV600. Only on XP sp2.
But with version 6.05
I download new drivers and software update from Geovision site to upgrade to version 6.1, and all work normaly.
Strange, you have 6.1
Myby try reinstall drivers, downloaded from Geovision.
I make myselve monitor. I use view finder from portable camcorder, mount it in head holder. Better than standart service monitors:
Both hands free
No problems in sunlight,
Kalatel has converters from kalatel to pelco, but only for basic dome functions, as a pan-tilt, zoom, focus. It is dificult use dome patterns.
And needs reset about 4-8 times per month.
