If the shutter speed to fast, less amount of light goes in and during night will the video captured too dark+noise although motion blur could be avoided?

You didn't say anything about shooting at night.  If you've got the ISO (sometimes called gain) cranked up, the aperture as open as it can be, and the shutter speed cranked up to where you don't see motion blur, there are only 2 ways to get a brighter exposure: 1. Add more lights. 2. Get a better camera.

Thanks for the info on ISO(called gain). I guess add more lights are better option.

Motion blur also depends on the speed of your subject. Are you trying to film a fast moving car or a tree in the wind?

@Bart I'm trying to capture a moving car. probably 40~50 km/hr.

@ Jason ppf is pixel per foot. It's a minimum requirement of object pixels that required.

I'm a newbie here. I have a problem that I don't really understand. Hopefully, someone can share their experience.

If I have an ip camera of

**1) 640x480(sensor width = 3.6mm)**,

**2) focal length from 5 to 50mm**,

**3) need to record 30fps**,

What is the suitable shutter speed to be use to avoid motion blur?Assuming that the object distance to camera is 30ft (80 ppf needed =~ 13.5mm lens focal length needed).
