DNR which stands for Digital Noise Reduction is an image processing technique which aims is to eliminate the visible noise from an image.
This technology is great for when you want to improve image quality when in low light settings and lower bandwidth, saving you storage!

Although you’d want high levels of DNR there are some negative effects when you take these settings to the max. You may find that there is a blur when there is movement in the image, this is similar to the blur that’s created by a slow shutter speed.
WHAT TYPES OF DIGITAL NOISE REDUCTION ARE THERE?
The two main types of DNR are 2D & 3D. With 2D – the technology processes each individual frame individually, whereas 3D DNR processes across a series of frames over time.
HOW DO I CHANGE THE DNR OF MY CAMERA?
It couldn’t be easier! Simply navigate your way through your UNV system with the following settings:
Setup > Camera > Image > Here you can change Digital Noise Reduction from 0 to 255
Across the UNV range, you will find that 3D DNR is used, meaning you get the best possible Digital Noise Reduction available
