Its high performance 960H 1/3” DS (double scan) CCD sensor offers a resolution of 720 TVL. The WDR function ensures the best image performance under difficult (high contrast) lighting conditions.   This AN 4000 series Bullet Camera is supplied ready to operate. It is suitable for challenging situations where fine tuning or special settings are required. The camera parameters can be individually set using the control buttons on the camera and an OSD for easy installation.     General   The camera features a high resolution 960H 1/3" DS sensor and IK08-rated, vandal-resistant and IP66-rated, water-resistant enclosure. The camera and included mounting bracket sport a black finish, while the sunshield sports a silver grey finish. Camera features include true WDR (Wide Dynamic Range) and enhanced Digital Noise Reduction.     Detail in Extreme Lighting   In harsh lighting, the difference between the brightest and the darkest parts of a scene can be extreme. To capture clear pictures in these conditions, the CCD sensor in the camera generates 2 images: one long exposure to resolve details in the scene's darkest areas and one short exposure to resolve details in the scene's brightest areas. The camera combines these dual shutter images, mixing pixels from each exposure to produce the most detailed image possible.     Built-in IR Illuminator   This integrated IR camera has 10 infrared LEDs providing up to 328' (100m) of night vision. The IR light pattern is optimized using special LED lenses to significantly improve light performance at the sides and in the corners of the image.     Day / Night Mode   The true day / night feature provides enhanced night viewing. The mechanical IR filter switches from color to monochrome mode automatically by sensing the illumination level.     Picture Performance   There are many settings available to help fine-tune the picture performance to match your installation environment. These include BLC (to automatically and dynamically compensates for strong backlight), HLC (to reduces glare from highlight areas), True Wide Dynamic Range (to extend dynamic range to see bright and dark details simultaneously), Contrast and Sharpness (to enhance details in bright or misty scenes), and Dynamic Noise Reduction (to dynamically reduce noise in the picture).     Privacy Masking   Fifteen different privacy zones allow specific parts of a scene to be blocked. Pre-program any part of the scene to be masked.     Video Motion Detection   The built-in video motion detector allows you to select four programmable areas with sensitivity thresholds. When motion is detected, alarms can be displayed in video signals.     Typical Applications   This day / night camera can be used in museums and art galleries, shopping centers, office, schools, colleges. universities, and petrol and gas stations.     Certifications and Approvals   FC: ANSI C 63.4:2003, FCC Part 15 Subpart B Class A UL: UL 60065, 7th Edition, 2007-12-11 CAN / CSA-C22.2 No. 60065-03, 1st Edition, 2006-04 + A1:2006 EU: EN55022:2010, EN50130-4:2011, EN61000-3-3:2008 LVD: LVD 2006 / 95 / EC, EN 60065:2002+A1+A2+A11+A12 IP: IP 66, KS C IEC 60529:2006 CE mark
