When considering how many images per second (IPS) are required for recording surveillance video in the event of the need for acceptable evidence, many considerations must be taken. IPS and "frame rate" are commonly interchangable terms. Most common considerations for selecting a specific recording frame rate include:
- Speed of moving objects
- Slight of hand
- Fluid motion desired
- Budget to store high frame rate video
- Existing hard drive capacity
This video to shows the difference between 7.5, 10, 15, and 30 images per second.
