Light Source LED for security systems
We can arrange LED as light source for security devices according to your own
specification
For CRIME PREVENTION (Infrared cameras)
As the light for crime prevention cameras, our LED's are widely used
in
| Parking lot |
| Entrances |
| Road |
By using the LED with high power and invisible wavelength, a clear
and distinct image can be taken without the notice of suspiscious
persons.
Adaptable wavelength:
We can prepare high power LED of 625nm, 635nm,
680nm, 700nm, 735nm, 760nm, 780nm, 805nm,
810nm, 830nm, 850nm, 875nm, 880nm |

For DETECTOR of INVISIBLE MATERIALS
Today, various kinds of invisible materials are used for safety
control in many objects such as bills, papers, etc. By using an LED with
specific wavelength as light source, these invisible substances can be
detected and checked. |
|
Adaptable wavelength:
We can prepare high power LED of 365nm, 370nm, 375nm, 380nm, and more. |
