Application: When IR camera becomes a problem

Engr.Jiang: The Senior Engineer of Security Division of the Imperial Palace Museum, Beijing, China. He has been in security industry since 1984.

"What is the problem with the Imperial Palace Museum for video alarm? Most of the structures are made of wood.When we use IR light, it generate high heat and baked the structure. Thus it can easily start a fire.That is not allowed.

But without sufficient resolution, the video alarm could not be generated. What should we do? That is a problem.

After years's searching we found a special camera, Black ray zero lux night vision camera. It can see words clearly in the total dark room, and its power is not high, meeting our requirements.

Now we installed several Black ray cameras at essential places. "

Zero Lux night-vision pick-up-image technology is different from the thermal imaging technology and the starlight night vision technology, the thermal imaging technology only can see the hot outline of human and the objects, and cannot see the real face of objects. Starlight night-vision camera can see the objects by certain moonlight, Star-light and environmental light, and could see nothing without light. Using infrared light source to assist camear also can see the goal, but cannot overcome the infrared light exposure and cannot observe under cover, easily exposed; and the image can be interfered by the light wave, they cannot achieve the same visual effect and clarity like the Zero Lux night-vision camera. Compared with the thermal and the starlight night-vision, the Zero Lux night-vision camera is the only night-vision imaging product,which could observe people and objects clearly from the monitor as the daytime when there is no visible light at night . 

Interference resistance. This product is not interfered by the environmental light, and can take the similar video image under different illumination conditions such as zero illumination, starlight and glare. 

Hidden in the dark. It can work completely hiding in entirely dark environmental condition,safe and reliable, satisfying the need of surveillance at night.

Clear as daytime.After the unique optics and the digital processing filter interference and noise, the video image taken in zero lux can be as clear as the image taken in visible light. It is extremely suitable for the surveillance monitoring use, is at present the clearest night-vision pick-up-image product of safe guard profession domestic and abroad.

The application way


◆ Regarding the important place where needs to strengthen the monitoring secretly at night, completely uses the Zero Lux night-vision camera to composite the Zero Lux night-vision supervisory system which hides completely and monitors in secret. It can obtain the perfect night-vision image.


◆ Regarding the important spot which needs to strengthen the surveillance monitoring at night to install the Zero Lux night-vision camera, the general spot installs the ordinary camera, constituting the surveillance supervisory system which partial monitors hiding in secret, partial light illuminating.
