Pelco DF5S-1 Overview The Pelco DF5S-1 is a low profile dome enclosure that can be used to discreetly house a Pelco fixed CCTV camera in an indoor location. With its 5" interior, this housing is suitable for Pelco's smaller camera and lens combinations. Pelco also designed it for easy installation, with a versatile fixed camera mount providing 360° camera positioning. Short Back BoxThe back box on this model is about 2.5" shorter than the back box on the standard domes, and is therefore suitable for use in celings with limited amounts of plenum space. This shortened back box version can also be mounted directly to a hard ceiling using an optional bezel (DF5S-SMKIT) to conceal the back box for a seamless integration.
