KT&C KNC-HDi47P4 - IP Camera Specification
This square IP camera uses a wide dynamic range (WDR) to alter the image when capturing in high/low light situations making the footage better quality. The HDi47P4 uses a 4.3mm pinhole lens and 2DNR to analyse individual video frames and to correct those pixels which are likely representing noise.
HD Resolution Capability
HD refers to high definition or 720p/1080p resolution, 1080p is known as Full HD. This resolution is a significant step up from 480p which can be seen in the image (on the right).
The first figure (1920) refers to horizontal pixels and the second figure (1080) denotes vertical resolution. The simple difference between HD and SD images is the number of pixels contained in the image

Benefits of IP Cameras
IP (Internet Protocol) cameras are powered over ethernet (PoE) and offer a far superior camera image quality/resolution to that of any other camera output. IP cameras can also be more cost-effective as they often cover a much wider range than that of an analogue camera. It would need up to four low-resolution analogue cameras to cover the same recording area as a single IP camera.

H.264 Video Compression
H.264 is a video compression for digital video recorders to use when reducing video file sizes without losing resolution in the captured footage. H.264 standard compresses the footage so that only half the storage space is used however the same video quality is maintained. Advanced Video Coding (AVC) uses Macroblocks to process information in 16x16px blocks.
Digital Image Stabilization (DIS)
Digital Image Stabilization (DIS) uses the motion detection core to stabilize the image from shaking due to external vibrations like oscillation and wind. It uses pixels outside the border of the visible frame to provide a buffer for the motion.
Wide Dynamic Range (WDR)
So what is Wide Dynamic Range? When part of an image is extremely bright but another part is so dark that you can't see any details, that's dynamic range—the difference in lighting. Cameras with wide dynamic range (WDR) have special software that allows them to balance that lighting for one clear image.
Backlight Compensation (BLC)
Backlight Compensation (BLC) technology works by reducing the dynamic range of the entire image while retaining the overall contrast. By compensating for unbalanced in a scene, the detail is restored throughout the field of view so as to provide better visibility to identify an object of interest.
3D Digital Noise Reduction (3D DNR)
Digital Noise Reduction (DNR) technology is crucial for a surveillance camera. 3D-DNR works by analysing the differences between successive frames in order to adjust pixels and improve quality. 3D-DNR reduces unwanted picture noise and compensates for image distortion due to colour blending errors
True Day/Night (TDN)
True Day/Night feature can be used for precise colour reproduction. With a built-in dual filter system, known as the Infrared Cut filter Removal (ICR) mechanism, the infrared cut filter can be used at day time, or in bright lighting conditions, to provide enhanced image in full-colour. At night time, or in harsh lighting conditions, it will be removed for greater light sensitivity in monochrome mode.
