STAR-LIGHT™ 2.1MP HD Over Coax™ 20X PTZ Dome Camera
Model: DWC-PTZ20X
The STAR-LIGHT™ HD COAX 20x PTZ Camera uses existing coaxial cables to transmit crystal-clear 1080p images in any lighting conditions and increase system ROI. The camera features 20x optical zoom and 16x digital zoom, 0~360° endless pan in an IP66 weather resistant dome housing. A wall mount and ceiling mount are available, sold separately and necessary to complete the camera’s installation.

PTZ and OSD Control via Coax (UTC)
UTC (Up The Coax) allows a user to access the camera's OSD (On Screen Display) through a coaxial connection, eliminating the need for an additional RS485 cable to reach the menu.
Tampering-Resistant Pan, Tilt, Zoom Domes
Digital Watchdhog® PTZ cameras use up to 30x optical zoom lens, which uses the internal glass elements of the lens to bring an image in closer and records over the entire digital sensor of the camera at full resolution. Combined with additional 16x digital zoom, the camera offers clear zoom up to 480x times. 
Wide Dynamic Range (WDR)
Wide Dynamic Range technology mechanically allows capturing an entire scene in challenging lighting conditions. One shutter is set to a short exposure, capturing the bright areas in the FoV, while the other is set for a long exposure, capturing the dark areas in the FoV. The camera then interlaces the images and combines them, capturing both areas with no loss of detail. This allows for an image capture even when there are very bright and dark areas in the camera’s field of view or images are distorted by a strong backlight.
