First thing to know is that wall mounting must be done relatively low say eye level to get the true panorama that vivotek highlights in their subway station video

And walk threw everthing with vivotek on team viewer for proper settings ajustments the works 2 days of frustration thousands dollars losts into camaras that dont see well at night 10 feet sorrounding is all you get of clearity im returing these cams are not worth the high dollar although purchased via another vendor i have 2 of these cameras they might not be what youd expect when you read 12mp some of the videos youll find from the vivotek website are clearly professional hype type videos they are not from the actual product although there are some if you look hard enough
