In the days of film cameras, there was a physical shutter blocking light from reaching the film; the shutter speed was the amount of time the shutter remained open to expose the film to light. The faster the speed (1/100s is twice as fast, or half the time, of 1/50s), the less light hit the film, and the darker the photo.

 

In terms of CCTV cameras, the "shutter" is electronic (ie. the amount of time the sensor collects data), but the concept is the same. Fast shutter = less light.

Fast shutter = less light.

Faster shutter speed also reduces the effective distance that moving objects can move during image capture, thus reducing motion blur. Thus, slower shutter speed can be useful in low light, but at the expense of increased motion blur.

 

Best,
