3. Example: 15-camera system
As an example, let’s consider a 15-camera system, with:
- 13 cameras recording at 5 FPS with 4CIF resolution,
- 2 Megapixel cameras recording at 3 FPS with 1600x1200 resolution.

We generally group small and large NVR Systems by the number of cameras they maintain. However, if the recording specifications of a
15-camera system are aggressive, resulting in a larger Total CIF-FPS, the resources of a typically larger system would be necessary.
Based on these calculations, the
5-15 camera Hardware Recommendations outlined in the next section will be sufficient for this sample system.
