This high speed dome PTZ camera has a complete Sony solution zoom camera, spherical privacy zone masking, five (5) levels of digital noise reduction (DNR), and smart pattern recording and playback. The megawatt infrared subsystem works with the zoom function to focus the infrared beam and eliminate hot spots. The camera module creates true HD 1080P real time video images.
SDI Output
Sometimes called Serial Digital Interface, the SDI format provides an easy way to connect new, high definition cameras to old coaxial-cable based CCTV networks. Since you don't have to replace cable, this means savings & no new cable required, no new installation charge. SDI security cameras connect directly to coax cable. Not only do they save money by using existing surveillance network infrastructure, SDI technology offers high definition images, true HD video, and clarity above and beyond any legacy analog CCTV camera output.
Dynamic Noise Reduction
Noise creeps into video images in surveillance networks from a variety of sources, sometimes from an unstable power supply and sometimes from spurious activity in the image pickup device. Some noise may be triggered by the scene itself, when something bright appears, when a sharply contrasting color passes through the area, or when a bright light or dark shadow crosses the front of the security camera. Dynamic noise reduction is a variety of methods used to eliminate noise, which appears as grainy imaging or blurred video. The OSD menu can be used to turn these features on and off and control how they function.
Backlight Compensation
When a video sensor images a scene it converts values of light into digital data. When an object is surrounded by light that originates behind the object, then details and color can be lost. Backlight compensation is a method that is built into the chipset and adjustable through the OSD menu that corrects data originating from this type of scene.
A camera without backlight compensation will often create a foreground image that appears too dark compared to the area surrounding it. The image appears like this because the sensor is compensating for the surrounding light. Backlight compensation protects the foreground subject and damps the surrounding light that might overpower the sensor. It helps to make sure that contrast, hue, and colors appear correctly.

These features are labeled as DNR, 2DNR, and 3DNR, depending on the product, and may include SMART DNR as well.
White Balance Correction
White balance problem manifest themselves in the way colors are reproduced in comparison to white, which can be used as a base for comparison. Photographs of winter scenes showing snow with a blueish-tint is a common manifestation of a white balance problem.
All light has different qualities depending on its source. Sunlight, florescent light, incandescent light and reflected light exhibit different color temperatures. Auto-tracking white balance makes sure the color white is reproduced accurately. Some surveillance environments present unique lighting challenges, and if color reproduction is important than you want to select a security camera that has white balance features.
