The Pelco BB4N-PB is the back box portion of a Spectra PTZ dome camera system. All Pelco Spectra series camera systems are made up of three key components - a back box (body), dome drive (camera) and lower dome (bubble). Pelco specifically designed it this way so that you can easily swap, replace or upgrade a part of the assembly without having to purchase a whole new system.
Built-In Memory
Built into this back box is a memory function that you can use to store camera and location-specific dome settings including labels, presets, patterns and zones. These can then be recalled even if this back box is used with a different camera.
