Benefits of Digital Noise Reduction

Understanding Noise

In order to understand the benefits of digital noise reduction (DNR) technology, we first have to understand “noise”. Noise is any unwanted disturbance in a signal. It can block, distort, change or interfere with the signal.


For example, you are having a conversation with a friend in a crowded restaurant. Your conversation is the signal, or the message you want your friend to hear. Any other noise you hear at the restaurant such as music or other conversations going on around you are noise.

  1. A cleaner signal
  2. A more visually appealing image

First, DNR delivers a cleaner signal, resulting in up to 70% disk space savings – so you can store more video evidence on your hard drive.


Finally, DNR technology makes it easier for your camera to distinguish between true motion and image noise – allowing for your DVR to be more efficient in motion detection – especially in low light conditions.
