All models of Raspberry Pi (including Raspberry Pi 3 and Raspberry Pi Zero W) have a CSI connector for connecting a digital camera. The foundation markets a color camera v2.1 equipped with an 8MP sensor and a sensitive camera in low light (v2.1 NoIR). You will also find cameras compatible with Led lighting cheaper at Asian manufacturers.
Original camera v2.1 or Night Vision (NoIR)?
The NoIR designation means No Infrared, ie the CMOS sensor is not equipped with the infrared filter. A more sensitive sensor with very low luminosity is obtained.
Original version Raspberry Pi or compatible asian camera?
Version 2.1 costs between $25 to $35 (Night Vision – NoIR – version). There are compatible cameras of good quality for less than $15. The official camera is equipped with a CMOS sensor Sony IMX219. Compatible cameras generally use a 5MP CMOS OmniVision OV5647 sensor. The OmniVision OV5647 sensor provides lower image quality. However, it is largely sufficient for night-vision video surveillance applications which do not require very high resolution.
Which camera for the Raspberry Pi 3?
The foundation offers two cameras. The first one designated v2.1 is a color camera based on the Sony CMOS CMOS sensor with a resolution of 8MP (3280 × 2464 pixels). CMOS (Complementary Metal-Oxide-Semiconductor) technology delivers excellent image quality even when the brightness is very high. Unlike the CCD (Charge Coupled Device), each pixel is independent of its neighbor. The pixels do not overflow on neighbors in bright light. This is the vertical banking trail (also called blooming) that can be seen on some digital photos.

The second designated camera v2.1 NoIR is equipped with a sensor on which the infrared filter has not been installed. The camera is more sensitive in low light.
Attention, some denominations are misleading, it is not a night vision camera. In full black, the sensor will be completely blind. On the other hand, by adding a complementary light (2 or 3 infrared LED for example), the sensor is (really) very powerful. In full black, you can hope to see at 10m, which is enough to make a surveillance camera. To learn more, you can read this detailed comparison.
Alongside the official Raspberry products, many manufacturers (mainly Chinese) sell compatible cameras. Very often the performance is lower but the budget is more reasonable.
Here is a brief summary of the main technical characteristics.

The CSI connector
The camera connector of the Raspberry Pi is called CSI connector for Camera Serial Interface. It is an industry standard managed by the Mobile Industry Processor Interface alliance. There are 3 standards (CSI-1, CSI-2, CSI-3) currently. The most recent version dates from 2012. The Raspberry Pi is equipped with a CSI-2 connector. The problem with the CSI connector is that there is no logo that makes it possible to be there as well rated Raspberry Pi and camera side. And it’s the same for the Orange Pi which is also equipped with a CSI connector incompatible with the Raspberry Pi camera!
Stay on familiar ground and check compatibility with the Raspberry Pi (or another mini-PC) at the time of purchase.
Which camera for the Raspberry Pi Zero W?
The Raspberry Pi Zero W (since revision 1.3) also has its camera connector CSI. But it is narrower than the one that equips his big brother: twisted:.
Fortunately, it is quite possible to use a camera v2.1 or v2.1 NoIR by replacing the flexible table with a compatible table (also called camera ribbon). This is the solution chosen by most manufacturers.
If you already have a camera, you can buy on Amazon for about $8. Live from Asia, we find for about $2.
There are also kits that integrate the ribbon compatible with the Raspberry Pi Zero W connector.

No posts for this criteria.Connect the camera to Raspberry Pi
The Raspberry Pi has a dedicated CSI connector. The CSI connector is located right next to the HDMI video output. Before connecting the camera to the Raspberry, stop Raspbian (sudo halt ) and unplug the card.
There is no direction indicator on the ribbon. Insert the ribbon by placing the tracks toward the HDMI connector.
Close the connector. It is locked by lowering it all the way down. There is no “click” that confirms the closing of the connector. Pull slightly to make sure the ribbon is in place and properly held. As you can imagine, this is not a foolproof mechanical assembly. Do not use too much mechanical action on the ribbon, otherwise the camera will be disconnected.
Enable Camera Module on Raspbian Stretch Pixel
Before you can use the camera module, it is necessary to activate it. Under Raspbian Stretch, open Menu and then Preferences and open the Raspberry Pi Configuration panel. Go to the Interfaces tab to activate the camera module.
Restart to complete camera activation.
Activate the camera under Raspbian Stretch Lite
Under Raspbian Stretch Lite (without GUI) but also from an external SSH connection, you can access raspi-config with the sudo raspi-config command. Go to menu (5) Interfacing Options.
Then to the menu (P1) Enable Camera and answer with Yes.
Restart to complete camera activation.
Test the camera with the raspistill command
Raspbian comes with a small utility that allows taking snapshots and saving small footage using the camera. This is the raspistill command. Open the Terminal
To take a snapshot called demo.jpg, the snapshot will be saved in the execution directory of the command, run
raspistill -o demo.jpg
You can add the -vf option to make a vertical rotation of 180 ° and -hf horizontally
raspistill -o -vf -hf demo.jpg
Run the raspistill command without arguments to list all available options. It is a very powerful command that can very easily be integrated into a Linux script without any other dependency.

Hi everyone.. i’m looking for the install and configuration of 3d printer to my arduino… someone know how to make it? i wanna print one model for this site https://www.stlfinder.com/
In the section called “The CSI Connector”, you have this sentence: “The problem with the CSI connector is that there is no logo that makes it possible to be there as well rated Raspberry Pi and camera side.”
That sentence makes absolutely no sense
