What is ultra-wide dynamic

Ultra-wide dynamic is a feature that allows the camera to see the image 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 camera looks out 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 CCTV camera will have a lot of problems in handling it. The traditional camera only has a 3: 1 contrast performance, it can only Choose to use the electronic shutter of 1/60 second to get the correct exposure of the indoor target, but the outdoor image will be cleared (all white); or the camera chooses another method of 1/6000 seconds to get the perfect exposure of the outdoor image, but the indoor The image will be cleared (full black). This is a long-standing defect since the camera was invented.
