What is an ultra-wide dynamic camera?

Ultra-wide dynamic is a feature that allows surveillance cameras to see images under very strong contrast. Wide dynamic cameras are dozens of times larger than traditional cameras with only 3:1 dynamic range. Natural light is arranged from 120,000 lux to 0.00035 lux in a starry night. When the surveillance camera looks out of the window from the inside, the indoor illuminance is 100 lux, and the illuminance of the outside scenery may be 10,000 lux. The contrast is 10,000/100=100:1. This contrast can be easily seen by the human eye, because the human eye can handle a contrast ratio of 1000:1, but the traditional closed-circuit surveillance camera has a lot of problems to deal with. The traditional surveillance camera only has a 3:1 contrast performance, which only Can choose to use the 1/60 second electronic shutter to obtain the correct exposure of indoor targets,

However, the outdoor image will be cleared (all white); or in another way the camera chooses 1/6000 seconds to get the perfect exposure of the outdoor image, but the indoor image will be cleared (full black).
