Essentially the problem has everything to do with how lights work. Camerasare not “ON” all the time. Camerasflicker on and off at a certain frequency and it is so fast that the naked eye can’t see.
NOTE: Most cameras nowadays have Flicker-less or Flicker-free settings to fix the problem and usually can be found under the Exposure Setup. Depending on your location the frequency is affected due to the power network. For North and South America, it is 60 Hz and in Europe, Africa, and Asia it will be 50 Hz.

You can experience camera flicker due to the frequency between the camera and the light source isout of sync. To get around this problem, the frame rate of your camera needs to match the frequency of the lights where you are at. The frame rate should be divisible by the number of light pulses.

For 60 Hz AC area they get 120 fluctuations every second, so you can set the Frame rate to 30 fps,60 fps, or 120 fps.

For 50 Hz AC area they get 100 fluctuations every second and frame rates at 25 fps, 50fps, or 100fps areideal but you won’t be able to get these frame rate adjustments. To go around this is by changing the Shutter Speed.

There is no perfect science in resolving this issue since every setup is different. It is a matter of checking if your camera has the Flicker-less or Flicker-free setting because most of the time this is overlooked. If that is not available, you can then play around with the camera’s Frame Rate and/or with the Shutter Speed.
