White light camera adopts domestic chip scheme, ultra-high resolution; resolution is higher than 700TVL, clear image, delicate camera, support automatic white balance function, high color reproduction, vivid image; support backlight compensation function, suitable for backlight environment Monitoring of foreground objects; high signal-to-noise ratio, clean and pleasing image; Taiwan energy-saving lamp beads, large illumination angle, strong brightness, long illumination distance and long service life.

Overview

The white light camera, also known as the white light camera, is similar to the infrared camera. It is a camera that provides nighttime low light camera. The biggest feature is that it is imaged at night.

White light: It is a new type of green lighting fixture that is energy-saving and environmentally friendly. It is a kind of visible light, which is a cold light source. It is widely used in the road monitoring project. The bayonet camera takes the auxiliary lighting tools of the motor vehicle brand of the past bayonet, and is used for the parking lot entrance and exit of the community parking lot. The camera records the auxiliary illumination of the motor vehicle brand. Because the camera captures the color of the camera in the auxiliary illumination of the white light at night, it can also be used for the auxiliary illumination of the camera at the gate of the enterprise. It is especially suitable for the single color camera. Used in conjunction with [1].

White light is matched with camera and lens: It is required to use low-light black-and-white, color or color-turning black camera, and choose cheap camera, the effective distance will be affected. Should also pay attention to the selection of the lens, the use of automatic aperture lens, the larger the F value of the lens, the better the CCD, the better the CCD is better than the 1/3" lens, 1/3" The lens is better than the 1/4" effect. The matching between cameras and lenses of different grades is different for the light sensitivity of the same white light, and the visual distance is also quite different.

advantage

No color cast during the day

Because white light is visible light, the infrared cut-off crystal filter is used. Of course, there is no infrared interference caused by the infrared filter, and there is no problem of outdoor color cast during the day. So the colors are more pure and the picture is more realistic.

Night vision full color

Because white light is visible light, the scenery that is seen is not much different from the daytime, and can provide more information, which is conducive to investigation and evidence collection.

Green lighting, energy saving and environmental protection: High-power white LED as a new type of green lighting source has been a global consensus. It has many advantages such as energy saving and longevity. Many countries are vigorously promoting it, which is the development trend of future lighting. When the white light camera is under the monitoring function, it also provides night illumination, which saves the user's investment in street lamps and the expenses of electricity charges.

Covert monitoring and warning: People who don't know think it is a street light, and it also has a hidden function. The person who knows knows that this is a surveillance camera and has a certain warning effect.

to sum up

As a new type of product, white light camera with white light as light source and fill light is still rare in the market. It is precisely because white light cameras are not common in the market, so everyone's profit margin will be relatively large. For example, if a project that requires bidding is used, everyone uses a traditional infrared camera to make a quote, then no one can dare to quote the price very high. In today's information age, users only need to simply consult and compare the product. The cost price is well known, and with the development of white light camera products, it has gradually gained recognition from all levels of customers. I believe that in the near future, it will replace the infrared one machine to become another myth in the security industry!

White light technology realizes one of the ways of nighttime color image monitoring, while the daytime monitoring image is more realistic and the color is more pure. Because white light is visible light, the infrared cut-off crystal filter is used, so there is no infrared interference caused by the infrared filter, that is, there is no problem of outdoor color cast. Today's society is promoting environmental protection, and white light is a new type of green light source. It is a consensus of the world, energy saving, longevity and many other advantages. Many countries have strongly supported and promoted it, and it is also the development trend of future lighting.

Market application

In applications, the technology that relies on natural light fills not only illuminates the space being monitored. At the same time, he can also display the color of the monitored area object more realistically, which is undoubtedly a function that is very much expected for users with night vision HD monitoring needs. In addition to being able to react to real-world situations, some of the details of the night vision are not available with active and passive infrared technology. However, due to the limitation of lighting hotspots, the monitoring distance is short. Generally speaking, the night monitoring range is less than 20 meters, and it is a good choice to use white light. However, the white light camera is less concealed, and the sensitivity of the white light camera is not very flexible, and it is prone to the biggest weakness of the surveillance camera such as the flashing phenomenon. In addition, if the person being photographed is prepared, the white light is easily reflected by others and it is difficult to pay attention to the details of the subject. Therefore, such night vision cameras are also more used in bayonet monitoring, road monitoring, or some small-scale monitoring requirements such as gates.
