The Cobra C309 PTZ Camera, designed for use with Cobra Crawlers, has all the features and functionality of our standard PTZ camera, in a smaller package. Using the latest LED Luxeon Star illuminators, the camera can inspect most pipe types up to 72” in diameter without the need for additional lighting. The C309 camera provides a 10:1 Optical Zoom. A 4:1 digital zoom is available, but is not recommended by Cobra. Digital zoom works by cropping and enlarging the image, interpolating (intelligently guessing) to create new pixels. This results in a blocky, low-quality image. Until this technology is refined, we believe the digital zoom hyped by many manufacturers is not useful in the field. Lights and camera share the same circuit, so when camera is powered, lights automatically illuminate at full brightness. This eliminates the need for a conventional Power Control Unit.
