The SD423-SMB-1 from Pelco is a Spectra IV SL Dome System (Back Box, Clear Lower Dome) includes a surface mount indoor black back box, a clear lower dome, and a DD423 Day/Night camera. The surface mount indoor back box can be easily installed to any type of ceiling. An integrated passive UTP circuit located on the door allows seamless transmission of videos via twisted pair wire. Additionally, for transmission over a single-mode or multimode fiber, Pelco fiber modules can be attached to the door assembly. The Spectra IV SL dome drive’s integrated optics package incorporates many advanced features that allow the system to produce high quality video in the most difficult environments. The camera features 23X optical zoom and 12X digital zoom. Spectra IV SL dome drives feature an EXview HAD imager for increased sensitivity and LowLight technology to compensate for scenes where minimal light is present. The camera also offers freeze frame between presets and window blanking.

A passive UTP circuit is located on the door assembly for convenient video transmission through twisted pair wire. For added flexibility, Pelco fiber modules can also be attached to the door assembly for transmission over single-mode or multimode fiber.Special consideration was taken when designing the Spectra IV SL lower dome bubble to ensure that an optimal optical relationship between the lens and bubble was achieved, providing crystal clear video at long focal lengths.
