Light Source LED for security systems


We can arrange LED as light source for security devices according to your own specification

PERSONAL IDENTIFICATIONS

Our LEDs are applicable to devices that recognize human characteristics.

bulletFingerprint
bulletVein pattern
bulletIris

 

Adaptable wavelength:
We can prepare high power LED of 735nm, 760nm, 780nm, 805nm, 810nm, 830nm, 850nm, 875nm, 880nm

 

For CRIME PREVENTION (Infrared cameras)

As the light for crime prevention cameras, our LED's are widely used in

bulletParking lot
bulletEntrances
bulletRoad

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
