Raspberry Pi Camera V2 Module features

The Raspberry Pi Camera V2 module is very tiny and it looks like this:

The Raspberry Pi Camera V2 features an 8 megapixel Sony IMX219 image sensor with fixed focus lens, it is capable of 3280×2464 pixel static images and supports 1080p30, 720p60, and 640×480p90 video.

The camera is compatible with all Raspberry Pi models.

Enable the Raspberry Pi Camera Module

To use the Raspberry Pi Camera module, you need to enable the camera software in your Raspberry Pi. In the Desktop environment, go to the Raspberry Pi Configuration window under the Preferences menu, open the Interfaces tab and enable the Camera as shown in figure below.

Or, in the Terminal window, type the following command:

You should see the Raspberry Pi software configuration tool. Select the Interfacing Options:

Enable the camera and reboot your Pi:

Connect the camera

Connecting the Raspberry Pi Camera Module is easy. With the Pi shutdown, connect the camera to the Pi CSI port as shown in the following figure. Make sure the camera is connected in the right orientation with the ribbon blue letters facing up as shown in the next figure.

Take photos with the camera

The easiest way to control the Raspberry Pi Camera is using the Python PiCamera package.

I recommend using Python 3 to run this script even though the PiCamera package supports Python 2. Create a new file called take_photo.py:

Copy the following code to your newly created file:

Press Ctrl+X to save your file, type Y and Enter.

When you run the script:

It takes a photo with the Raspberry Pi Camera and saves it with the test_photo.jpg name:

Recording video into a file

The next Python script also uses the PiCamera package to record video into a file.

Create a new file called record_video.py:

Copy the following code to your newly created file:

Press Ctrl+X to save your file, type Y and Enter.

When you run the script:

It takes 5 seconds video with the Raspberry Pi Camera and saves it with the test_video.h264 name. You can modify the script to set the camera resolution and extend the video recording duration.

To watch the video on Raspberry Pi with the Raspbian Desktop environment, you can use the omxplayer software.
