- The new CC-5XDWDR Color Weatherproof Bullet Camera has incredibly clear 700 TV lines of resolution, Digital Wide Dynamic Range and 2D Digital Noise Reduction.
- The wide dynamic range (WDR) function of a camera is intended to provide clear images even under extreme light circumstances where intensity of illumination can vary excessively, namely when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame, in a way that there are details in both areas, i.e. bright areas are not saturated, and dark areas are not too dark. It also offers amazing low light capability.
- Digital Noise refers to the random dot pattern that is superimposed on the picture as a result of electronic noise; the 'snow' that is similar to what can be seen with poor (analog) television reception or on VHS tapes. The Digital Noise Reduction feature reduces that "noise" from the cctv camera image.
- This is the best bullet camera we have seen in terms of performance.
- If you are installing a new system or upgrading an existing one this would be the best choice. It is cutting edge so you won't have to worry about having out-dated equipment 6 months from now.
