Low light conditions are always challenging for surveillance cameras. In some cases , capturing the details at night can be vital. Leader manufacturers of surveillance industry working on this issue and developing better technologies everyday. There are three main factors that are necessary for providing a good night vision.<\/p>\n\n\n\n

Firstly, lens of the camera must be gathering light as much as possible and delivering with minimum loss to the sensors in a very low light environments.<\/p>\n\n\n\n

Secondly, sensors must have a large surface which provides a bigger area per pixel. This allows more lights being received and reduce the noise generated from heat.<\/p>\n\n\n\n

Finally, system requires high complexity image processing technology. When the noise in an image decreases, data size also reduces. This saves more storage space and needs less bandwidth.<\/p>\n\n\n\n

Hanwha Vision<\/a>\u00a0one of the frontiers in surveillance industry- released their latest Wise NR Technology that provides a much better visibility at very low light conditions.<\/p>\n\n\n\n

Hanwha Vision<\/a>\u00a0states that \u201cWise NR featured in Wisenet X Series cameras is a 3-DNR technology combining Hanwha Techwin’s noise reduction technologySSNR (Smart Super Noise Reduction) and other technology and experience the company has developed. It featuresadaptive motion detection (AMD) technology and a powerful pattern matching technology optimized for low light levelenvironments prone to generating high noise levels.<\/p>\n\n\n\n

With AMD technology, it compares the current image with the previous frame to identify areas with movement, and applies2-DNR based on pattern matching in areas with movement to produce a clear image with no afterimage. 3-DNR is appliedto areas without movement to not only remove noise but also to restore information lost due to noise and physical limitations.Through doing so, the image will contain accurate information which was not clear in the original frame. Furthermore,with Wise NR, the image is encoded with a low bit rate allowing the image to retain its clear image quality even when beingtransferred and stored efficiently.\u201d<\/p>\n\n\n\n
