Picking up good video images during the day can be hard enough with all the random factors you can't control, but picking up good images at night is always more difficult. And night time is when people become much more concerned about image pickup. Slow shutter speed is a technique that, essentially, allows the video sensor of a CCTV camera to accumulate enough light to operate in conditions the human eye would perceive as complete darkness. It is sometimes called Sens-up, Sense Up, or similar variations, and depends on controlling the electronic shutter integral to electronic video sensor operation. To understand Sens-up (or Sense Up), you must have at least a basic understanding of electronic shutter operation.
