What is an IR(Infrared) Sensor?
What is Infrared?
Infrared (IR) is also known as radiant energy.
It is electromagnetic radiation that has longer wavelengths than visible light.
Normally, human eyes can view light with a wavelength ranging between 320nm – 760nm.
The IR ranges between 700nm to 1000nm on the electromagnetic spectrum,so our eyes cannot see these infrared waves.
What is an IR(Infrared) Sensor?
We cannot see these IR waves but instruments that can sense infrared energy.
Infrared(IR) sensor is a combination electronic device, including transmitter and receiver.
The emitter is an IR LED and the detector is an IR Receiver.
When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver.
An IR sensor can measure the heat of an object as well as detects the motion. Usually,
in the infrared spectrum, all the objects radiate some form of thermal radiation.
These types of radiations are invisible to our eyes, but infrared sensor can detect these radiations.
An Infrared technology implemented in night vision equipment if there is not enough visible light available to see unaided. Night vision devices convert ambient photons of light into electrons
and then amplify them using a chemical and electrical process before finally converting them
back into visible light. Then we can "see".
Smart IR technology
Smart IR technology : Reduces Over-exposure of the IR LEDs at the Center of the Image.
Smart IR technology was invented to solve the problem of infrared LEDs whiting out images,
such as people’s faces, when they are too close to the IR LEDs of a night vision camera.
IR Range
All devices that have on board infra red illumination will illuminate objects at the identification distance for the lens fitted.
Our products have 65ft~131ft diffrence specifications that can choose.
IR-Cut Filter (ICR)
While IR is an important feature for night-vision recording, but
the infrared light distorts the colors of recorded images.
so we shold use an IR-cut filter to ensure great image quality during both day and night (low-light) conditions.
