2. Night vision surveillance technology can be divided into active infrared technology and passive infrared
technology. As this, night vision products could divided into two categories: active night vision products
(like general infrared camera and laser infrared camera)and passive night vision products (like low light
night vision camera and infrared thermal camera).
What is Night vision infrared technology

3. Something about thermal imaging01
Thermal imaging is the technique of using the heat given off by
an object to produce an image of it or to locate it All objects
have a certain temperature and emit waves of energy called
infrared radiation. Hot objects emit more energy than cold
objects. A thermal imager translates these energy waves into a
viewable image, which shows a “heat picture” of a scene. On
the screen of a thermal imager set to white-hot, hotter objects
show as white, cooler objects show as black, and objects in
between these temperatures are displayed in shades of gray.

F e a t u r e
1. thermal cameras work is by “seeing” heat energy from
objects.
In the actual application environment, people and other
common animals, vehicles, roads, water surfaces, houses,
etc. have different infrared characteristics.
For example, the human body and the vehicle are typical
strong infrared radiation sources, so the image brightness is
high;
The water surface is a typical infrared absorption source,
and the image brightness is almost zero. Therefore, it is
easy to distinguish the above-mentioned targets. That is,
infrared has a natural selectivity for the target of interest,
which is extremely advantageous for military applications
and assisted driving applications.

2. Infrared imaging is an intrinsic property of the target. It has
nothing to do with the existence of a light source in the outside
world. It is only related to the infrared radiation of the object.
Therefore, it can work under day and night and with or without
illumination, and the performance is exactly the same.
3. Due to the longer infrared wavelengths, the ability to
penetrate smoke and fog is much stronger than that of visible
light. Usually, mist and fog do not have any effect on infrared
imaging.
4. Another advantage of the long wavelength is that the
diffraction ability is strong, there are stains on the lens or
partial occlusion in front of the lens does not cause the visual
effect of infrared imaging basically, is subject to less observation
conditions, and is easy to maintain.
5. Infrared imaging is completely passive, with no interference
between imaging systems and without revealing itself.

6. Advantage of Thermal Imaging
Observe the target within a range of 1 to 2 km depth at the same time
1KM human1.5km human

7. Disadvantage of Thermal Imaging
can't identify human face
IR laser Thermal imaging

8. NIR Laser
The laser camera is equipped with laser light source
on the surveillance camera. The laser light adopts the
spot intensity enhancement technique, and auto
focus technology, has the feature of strong luminosity,
more uniform image, Low Power Consumption and
longer lifetime.
Laser night vision technology is one of the ways to
achieve long-distance surveillance at night , because
the laser has a high brightness, good coherence,
good monochromaticity, good direction, long life and
CCD wavelength of its induction is greater than the
LED characteristics Determines that the laser can
illuminate farther distances, and that the light
intensity is much stronger than the common light
source.

9. I R l a s e r
F e a t u r e
Compared with ordinary infrared camera, the features and
advantages of laser camera：
1. Long surveillance distance. According to the surveillance
distance,Laser cameracan be divided into short-distancelaser camera
(effective night vision distance is 100-500 meters) and middle -
distance laser camera (effective night vision distance is 500-1000
meters) and long-range laser camera (effective night vision distance
is 1000-3000 meters).
2. Could adjust the focal length automatically , clarity greatly
improved. Although the ordinary infrared camera will see the image
at night, but usually can’tsee the faceclearly,
3. in addition, the surveillance distance of ordinary infrared camera
is limited, Laser camera can ignore the strength of light, through the
laser infrared components and ultra-low light optical components,
the camera can see clearly at total darkness , Many laser cameras
have a certain intelligent function, it can automatically adjust the
length based on the object’s distance and movement speed in order
to provide a clear image.
