30 vs 60 FPS Shootout

Author: Ethan Ace, Published on May 21, 2013

30 frames per second used to be the maximum practical limit for surveillance cameras. Now, it is becoming increasingly common for IP cameras to support double that, 60 frames per second. (For background, see our training on frame rates and industry statistics on average frame rate used.)

30 vs 60fps Testing

We took two identical cameras and kept all settings the same except one was set to 30fps and the other 60fps. We then filmed and analyzed 3 scenarios.

Rapidly flipping through a stack of 50 bills in 2 seconds:

Counting money:

Car driving 50mph:

 

We did this to answer three key questions:

  • How much of a practical benefit did the extra frames deliver?
  • How much did bandwidth increase for 60 vs 30fps?
  • Was there any reduction in blurriness for higher frame rate?

John *, I didn't see much difference between 30 and 60 FPS as far as motion blur goes. However, changing to 60 FPS moves the maximum shutter speed from 1/30s to 1/60s, so you're letting in less light, and that shows. It's not a giant difference because the 733V is very capable in low light, but it's noticeable. It would likely have to be extremely dark (we're talking two decimals or more) to have much impact, because even under 1lx right now, the 60 FPS image is quite bright.
