Introduction:

The Camera is an one best add-on hardware module for Raspberry

Pi.Many Pi users are mainly focusing on Computer Vision(CV) projects and we can

use it for live streaming,webcam security system, and mobile applications too.For a

students it is an amazing oppurtunity to learn raspberry pi and an add-on hardware

like this camera module and still more.In this step by step guide we will explain how to

install the raspberry pi camera module ,along with how to take pictures and video.

Camera Specification

Pixel 5MP

1080P30,720p60
