Motion detection is the process of detecting a change in the position of an object relative to its surroundings or a change in the surroundings relative to an object.

Motion detection can be achieved by either mechanical or electronic methods.

When motion detection is accomplished by natural organisms, it is called motion perception.

A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.

The images may be individual still photographs or sequences of images constituting videos or movies.

The camera is a remote sensing device as it senses subjects without physical contact.

The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.

The modern photographic camera evolved from the camera obscura.

The functioning of the camera is very similar to the functioning of the human eye.

Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color categories, with names such as red, yellow, purple, or blue.

This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light.

Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them.

This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc.

An electric light is a device that produces visible light by the flow of electric current.

It is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities.

In technical usage, a replaceable component that produces light from electricity is called a lamp.

Compact lamps are commonly called light bulbs; for example, the incandescent light bulb.

Lamps usually have a base made of ceramic, metal, glass or plastic, which secures the lamp in the socket of a light fixture.

The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap.

A loudspeaker (or loud-speaker or speaker) is an electroacoustic transducer; which converts an electrical audio signal into a corresponding sound.
