White camera

What is a white camera A white camera, also known as a white light camera, is similar to an infrared camera in that it is a camera that provides night-time dimming. The biggest feature is that it is imaged in the night as a color image.

White light: It is a new type of green lighting device that is energy-saving and environmentally friendly. It is a kind of visible light and belongs to the cold light source. It is widely used as an auxiliary lighting tool used by bayonet cameras to capture the passing car number of the passing bayonet in the road monitoring project. It is used for the entrance and exit of residential parking lots. The camera records the auxiliary lighting of the motor vehicle license plate. Because the camera is under the auxiliary lighting of the white light at night, the captured image is colored, so it can also be used for the auxiliary lighting of the camera in the gate of the enterprise and institution, especially suitable for the same color camera. Supporting the use of.

White light and camera, lens in the match: the requirements of low-light black and white, color or color to black camera, choose a cheap camera, the effective distance will be affected. Should also pay attention to the choice of lens, requires the use of automatic aperture lens, the larger the better the lens F, CCD is bigger, the better, use 1/2 "the lens is better than the use of 1/3" effect, use 1/3 " The lens is better than the 1/4" effect. The matching of cameras and lenses in different grades has many times the sensitivity of the light emitted by the same white light, and the visibility distance is also much different.

Applicable occasions: Generally speaking, the night monitoring range is within 20 meters, and the use of white light is a good choice.

Insufficiency: The camera is less concealable.

Structure and Principles In the field of camera technology, there are a variety of types of fill light technology, such as infrared light, ultraviolet light, laser light, blue light, white light, and thermal imaging technology. However, among these lights, only the white light fills the camera at night to capture color images. The color temperature and wavelength of white light directly reflect the quality of the image obtained by the night camera. People use the absolute temperature of the complete radiator that is equal to or similar to the color temperature of the light source to describe the color table of the light source (when the human eye directly observes the light source To the color) also known as the color temperature of the light source. The color temperature is expressed as an absolute temperature K. Different color temperatures can cause people to respond differently to emotions. We generally divide the color temperature of light sources into three categories:

a. Warm light: The color temperature of the warm light is below 3300K. The warm color light is similar to the incandescent light color, and the red light component is more, giving people a warm, healthy and comfortable feeling.

b. Warm white light: Also called the middle color, its color temperature is between 3300K-5300K. Warm white light and soft light make people feel happy, comfortable and peaceful.

c. Cool color light: also known as daylight color, its color temperature is above 5300K, the light source is close to natural light, has a bright feeling, makes people concentrated, suitable for offices, outdoor squares, classrooms, design rooms, channels, and other places.

Color rendering: The degree to which a light source presents its color is called color rendering, which is the degree of realistic color. A light source with high color rendering performs better on color, and the colors we see are closer to natural colors. Low light sources perform poorly on color, and the color deviations we see are also larger.

Why is there a difference in color rendering? The key lies in the spectral characteristics of this light. The wavelength of visible light is in the range of 380mm to 780mm, which is the range of red, orange, yellow, green, cyan, blue, and violet light we see in the spectrum, if the light source emits light. The proportion of light contained in the light is similar to that of natural light, and the color seen by the camera CCD is also more realistic. With the efficient and stable white light-filling device, the quality of night-time camera color images will be greatly improved.

The performance of the product The unique product features of the white camera make it impossible for other cameras to compare and exceed.

Power Saving: Whether it is installed indoor or outdoor, the white camera can serve as an emergency luminaire when the outside world suddenly loses power, especially in indoor areas, corridors, basements, etc., and the effect is even more remarkable.

Color: White camera fixed focus series adopts pure color high-line low-light SONY 1/3 CCD Daytime color reproduction is more real, night is at 0. In the LUX environment, color images can be clearly captured, and the surveillance system can be truly monitored and monitored throughout the day.

Reliability: Stable imported LED white wick, matching circuit design strict voltage and current control, perfect body heat conduction system structure, making the white light fill system service life from theory to reality, the world's advanced CCD substrate program, strict The success rate of the patch process is 100%.

Market Analysis Currently, infrared cameras are commonly sold on the market, and can be said to be flooded. With the continuous maturation of products, price transparency, market openness, and the price of infrared cameras have entered the era of melee war, giving The security industry has had a serious impact. If this situation continues to worsen, the wolf will have less meat and will certainly create a situation where a group of people will compete.

White light camera as a new type of product, with white light as the light source, fill light camera is still rare in the market, it is precisely because the white light camera is not common in the market, so everyone's profit margin is relatively larger. Example: If a project requires a bid price, everyone uses a traditional infrared camera to make a quote. Then everybody dares not report the price very high. In today's information era, users simply consult and compare products. The cost of the price is well-known, and with the advent of white light camera product development, has gradually been recognized by customers at all levels, I believe in the near future, it will replace the infrared one machine to become another myth in the security industry!
