The clear High-Resolution Acrylic Bubble from Bosch protects the AUTODOME 7000 IP cameras (PAL models) with in-ceiling housing and offers enhanced image clarity. This low-impact clear bubble offers maximum sensitivity by allowing as much light through as possible. It adds 0.09 f-stop loss (90% light transmission). The bubble comes assembled with a white ring and also includes an optional black ring. If you want to use the black ring, you can swap the ring. The bubble fits any small in-ceiling can for VG4, VG5-1xx, and VG5-6xx camera models from the 7000 Series.
