Frame by second
The image per second or more accurately the number of frames per second is a unit of measurement that corresponds to the number of images displayed by a video taken with a camera. It may be a surveillance camera or a spy camera.
Indeed, when you watch a video, you get the impression that you see a moving image. However, this is not the case. In reality, what you see is a succession of still images that are released very quickly one after the other. Your brain is then bombarded by a continuous stream of visual stimulation. To manage these flows, it performs a kind of synthesis of all visual changes to have an impression of movement. This is called the phi effect.
The number of images broadcast per second affects the fluidity of the animation. Indeed, the higher the number of images, the more fluid the animation. This is because the increase in the image allows the brain to better understand what is happening. It is an unconscious phenomenon and the increase in the number of images per second contributes to the viewer's sense of comfort. Note that motion printing can already be perceived from 5 or 6 frames per second. Only after the film industry standardized it into 24 frames per second, but with devices like our spy camera range, you can reach 30 frames per second.
