Differences Between Niankang Night Vision and Infrared Vision

Compared to infrared night vision, the biggest core difference of full-color night vision lies in the color of the image at night and the way it uses fill light. Full color night vision can maintain the color image of the original image at night, rather than the black and white image like infrared night vision. The ability of full-color night vision to maintain the color image of the original image at night mainly relies on the assistance of its low light sensor, which can also be supplemented by white light lamps.‌‌‌

Compared to the previous image, the color tone of this painting is even darker, especially the pitch black background, which gives a stronger visual impression

But through infrared night vision systems, we can only present it in black and white monochrome images, where we can clearly see the contours, movements, and height of the human body, but we cannot see the color of clothing, the color of vehicles, or details of the face.

With the full-color night vision function, not only can a scene of real color images be clearly seen in the dark night, but also a series of key identification information such as the color clothes worn by the suspect, the color of the car driven, and the license plate number can be clearly seen, which is of great significance for the investigation of cases.

Due to its almost invisible and difficult to detect infrared night vision (especially in the 940nm wavelength band), it has good concealment. However, if the white light supplement is turned on for full-color night vision, there will be visible brightness, making its relative concealment relatively poor.‌‌‌

What is the difference in working principle

Infrared night vision:

The principle is that the infrared LED lights around the camera emit 850nm or 940nm infrared light that is invisible to the human eye, and the emitted infrared light is focused on the target, which can be seen by the human eye.

By precisely illuminating it with infrared light, all the reflected infrared radiation is reflected back onto the lens and captured by the infrared sensor for imaging.

Although the harm caused by the red glow of 940nm laser is significantly reduced compared to 850nm laser, its irradiation distance is also greatly shortened, about 10-15 meters.‌‌‌

Full color night vision:

It can be achieved through two methods: low light full-color (large sensor+large aperture, capable of outputting color under a weak light of 0.001Lux) or white light complementary full-color (i.e. an LED light that can automatically light up a white light in front of a person).

Upgrade it to a dual light full-color night vision solution, which can be implemented in the form of energy-saving infrared night vision during normal work. Once a person is detected, it can automatically switch to full-color high-definition night vision, and after the person leaves, it can switch back to the energy-saving infrared night vision state.‌‌‌

How to choose more suitable

The best scene to fully demonstrate the function of night vision is undoubtedly the dark forest without lights at night. Suddenly, green light beams shoot out one by one in the midst of the darkness. The dark forest around the light beams suddenly becomes transparent, and all kinds of animals are clearly standing under the light beams. All kinds of insects are also clearly flying on top of the light beams. The entire dark forest at night suddenly becomes bright and magnificent

Bright lighting should be provided for areas such as entrances, garages, lanes, and shops that require us to clearly see the colors of people, cars, and items.

Exploration and implementation of various application scenarios of security based on the strongest evidence.

If there is a faint moonlight outside the window or a few strands of light shining through the door crack, the living room or hallway can be clearly seen in the darkness.‌‌‌

Through the optimization of infrared night vision, night vision scenes can now be transformed from traditional "black and white" to "colorful" panoramic images, enabling various combat tasks such as observation, ranging, tracking, and identification at night. Completed with the greatest convenience and speed

You can clearly care for the elderly, children, pets, etc. one by one in the dim light of the room without having to use the external filling light of strong white light.

In order to provide the best covert support for hidden surveillance scenarios that we do not want to be discovered, we have specially launched a series of 940nm products without red light.

Because the inner sides of balconies or windows are prone to direct reflection of white light, the uniformity of the full-color effect during shooting is greatly compromised.

Relying on the infrared irradiation of open areas such as outdoor courtyards, parking lots, and warehouses, its infrared detection range is relatively farther and more reliable.‌‌‌
