why we use LED in a hidden CCD camera?
Yes
CCD = Charge Coupled Device.
In the past, cameras took still photos and videos by focusing light on film. Now, in a CCD video camera, the lens of the camera focuses light onto a small CCD sensor. CCD stands for "charge-coupled device."

The price of a color CCD camera can vary depending on the brand and features. Most color CCD cameras are between $200 and $1200. There are a lot of factors that go into choosing one and the CCD camera with the best features tends to be the one that is the highest price.
A CCD camera uses a special chip which detects light photons hitting an array. This data is then converted to binary which can then be interpreted by the camera into an image.
The Sony A100 was the first digital single-lens reflex camera (DSLR) produced by Sony. The camera uses a 10.2 megapixel APS-C size CCD sensor. Another feature is the automatic vibrating CCD to remove dust.
The CCD is the part of the camera that changes the light that enters the camera into a digital signal that is then saved on the memory card. You can think of it as where the film would be in a regular 35mm film camera.
One of the best types of cameras to attach to a microscope for specimen images is a CCD camera. A CCD camera is also known as a charge coupled device camera.
