Bandwidth spikes in low light are commonplace, with increases of 300 to 500% over daytime normal.
IPVM recommends lowering bandwidth levels at night, relative to those spikes. For example, if your camera consumes 2Mb/s during the day, but 10Mb/s at night, you can easily cap it to 5Mb/s (or even less) without any quality loss. This can reduce overall storage costs by 50%.
In this report, we share our test findings of multiple cameras set to average compression levels and then to high compression level to answer the following questions:
- What visible difference does high compression video have in low light?
- Are human subject or text details more difficult to discern at higher compression levels?
- How did this increase in compression impact bandwidth?
