Training: Frame Rates for IP Camerasby John Honovich, IPVM posted on Apr 19, 2010 About John Contact John
Selecting the 'right' frame rate is one of the most frequently discussed and debated aspects of video surveillance. Make a mistake and one can miss key evidence or significantly increase storage cost.
Inside the Pro section, we provide an 11 minute video screencast that explains and demonstrates the fundamentals of resolution. We include 6 video sample clips for members to download featuring 2 scenes: (1) a person walking normally and (2) playing cards being dealt. Each scene is filmed at 1, 5 and 30 frames per second to show the practical differences.
The video screencast and downloads should help you answer the following 10 questions:
- What is the definition of frame rate?
- How is frame rate measured?
- What is the range of frame rates used in video surveillance?
- How does IP impact maximum frame rates compared to analog cameras?
- What is the key risk of too low frame rates?
- What is the key risk of too high frame rates?
- How does the video of a person walking differ between 1, 5 and 30 frames per second?
- How does the video of cards being dealt differ between 1, 5 and 30 frames per second?
- What frame rates should you use for what applications?
- How much can storage vary depending on selection of frame rates?
