What is the photosensitivity of a matrix?

The photosensitivity of a matrix refers to its ability to capture light and convert it into an electrical signal. In the context of cameras, a matrix (also known as an image sensor) is the component that captures the image and converts it into a digital signal. The photosensitivity of the matrix determines how well the camera can capture images in low light conditions.

The higher the photosensitivity, the better the camera will be able to capture images in low light. This is an important factor to consider when choosing a camera, especially for surveillance purposes where monitoring may need to occur in both well-lit and low light conditions.

The camera automatically switches to black-and-white mode at night, as black and white contrast vision can be better than color. Additionally, turning on IR illumination further improves the resulting image quality. This allows the camera to remain effective even in complete darkness. The illumination level is measured in Lux.

Examples of illumination values:

Moonless night: 0.01 lux

Moonlit Night: (1/4 of the Moon): 0.05 lux

Starlight Night: 0.003-0.1 lux

At night on the street with the full moon: 0.3-0.1 lux

Deep Twilight: 1 lux

The auditorium in the theater: 3-5 lx

Twilight and illuminated highway at night: 10 lx

Warehouses: 75-30 lux

Offices: 50-500 lux

Hotel halls: 100-200 lx

Shops and supermarkets: 1500-750 lux

Daylight on the street in cloudy weather: about 5,000 lux

Daylight on the street in sunny weather: 100000-5000 lux

When manufacturers describe the "visibility" of a camera, they are referring to its ability to capture a minimum level of illumination of the subject or object being monitored. However, this does not guarantee high image quality. It is recommended to choose a camera with a photosensitivity parameter that exceeds the illumination level of the object or subject by several times in order to ensure optimal image quality.
