For small systems, using DNR and region prioritization can translate into the ability to provide a higher frame rate for smoother video when moving objects are present, while still achieving the desired retention time and staying within the budget.
For this example, think about a typical 10-camera installation at a small retail store. Using 10 720p HD indoor cameras recording continuously for 12 hours each day and then recording when there is motion after the shop is closed, you can store video streamed at 10fps for seven days using a 4TB storage appliance. Now, consider the same scenario using DNR. With DNR, you could stream video at 20fps and achieve the same retention time using the same 4TB storage appliance. The end user gets smoother motion video for the same cost.
Using these examples, it is easy to see how this type of technology can provide you with cost savings. And, it will become even more important as the industry moves toward the next generation of imaging such as 4K Ultra HD resolution, with even higher data volumes and therefore higher bandwidth and storage requirements. Ultimately, the solution that provides the highest quality video with the lowest bandwidth and storage requirements will often be the most desirable choice.
