What is a starlight camera?

In terms of camera function classification, starlight level camera is a kind of low illumination camera.

Low illumination camera is a camera that can take a clear image under low illumination conditions. According to minimum illumination to judge the disadvantage and advantage for low illumination camera.

However, since there is no unified international standard for management, each large image sensor manufacturer has its own measurement standard. The starlight camera is a level of low-illumination camera, which is usually classified as below:

0.1Lux: Dark light level

0.01Lux: Moonlight class

0.001Lux and below: Starlight

Therefore, a star-level camera refers to a camera that can display a clear color image without any auxiliary light source under low light conditions, usually under a starlight environment. A camera capable of color imaging at night can greatly improve the monitoring effect.

At the same time, the starlight level has an ultra-sensitivity image sensor and a unique electronic multiplication and noise control technology that can greatly improve the sensitivity of the camera, and has a 24-hour full-color real-time effect, effectively avoiding the phenomenon of tailing of ordinary low-illumination cameras, better Satisfies the need for high-quality monitoring at night, with low power consumption, real image effects, and no color cast.

So, besides the star level, what other common low-illumination cameras are there? What are the different functional advantages of starlight cameras and other low-light cameras?

Types and characteristics of low-light cameras:

1. Infrared night vision camera

Infrared night vision cameras are mainly used in dark environments without visible light or low light. The infrared light is used to actively project infrared light onto objects. The infrared light is reflected by the object and enters the lens for imaging. This method has become the most common application solution with its most mature technology, widest application range, and highest cost performance.

For example, our infrared night vision USB camera module adopts the configuration of 850NM infrared LED, which makes the distance of night vision farther and the effect clearer.

2. Starlight level camera

However, in actual application scenarios, due to the limitations of black-and-white images and shooting distances of infrared light cameras, and the limitation of the need for additional supplementary lighting tools for white light cameras, they cannot really meet the needs of scene shooting under low illumination, so we launched the use of starlight The camera module of the image sensor.

IMX291 CMOS sensor is a classic star-level senor. Compared with the low illumination of ordinary network cameras, the effect is better. It not only can meet the requirements of star-level (under 0.001lux and below, without any auxiliary light source, but also can showing clear color image). Here is our IMX291 Starlight usb2.0 1080P Camera Module.
