Important notice

The connector for the camera has connections on both sides so the cable has not to be twisted to align the camera properly. The drawback of that is that you can destroy the camera and your raspberry pi module if you connect it wrong! On the connections board pin 1 and 15 are marked. make sure to connect pin 1 from your camera with pin 1 from the PiCam board. For the Pi HQ camera you can hold the camera over the board like it would be normally positioned insert the cable properly on the camera and without twisting the cable connect it to the PiCam module.
Power the Picam

Connect your USB micro b connector to the left usb slot.

First test

The device will boot and start a hotspot.

SSID: taskit pi cam

password: 12345678

Connect to the hotspot, open a web browser and navigate to http://192.168.42.1/

The login for the Motioneye setup are the defaults. For admin access username admin and no password.

For normal user access both can be left empty.

Username: admin

Password:

The raw video footage is located at http://192.168.42.1:8000/video_feed

Connec the PiCam to your wifi

Open a web browser and navigate to http://192.168.42.1:8080. Select the Wifi you want to use and input your wifi password.

When you confirm your wifi settings you will get the notice below.

PiCam has closed its hotspot and tries to connect to your wifi with your settings.

Any other inputs you do now will not be sent to the PiCam.

If you get the following notification you have already clicked on connect and are disconnected.

So any changes you did wont be applied.

Connect to your PiCam in your Network

You can access the PiCam with the url taskitpicam.local in your browser.

If you want to use its ipv4-address send "ping taskitpicam.local -4" from your command line and use the ip.
Using multiple PiCams

When you add a second PiCam to your network the second cam will set its hostname to taskitpicam-2.local every new PiCam will iterate on that.

To access the additional PiCams follow the steps from Connect to your PiCam in your Network.
Use the camera without tenserflow

You might want to disable tenserflow(Object detection) to get a smoother video feed.

To do that use your favorite SSH client and connect to the Pi. The login data are the default raspberry pi logins.

User: pi, password: raspberry.

Run systemctl stop tflite_example.service followed by systemctl disable tflite_example.service.

Now that you have disabled tenserflow you can go back into your webbrowser and navigate to taskitpicam.local.

If you are not logged in as admin click on the little person and login as one, with User: admin and no password.

Delete the existing camera setup by clicking on the trashcan and add a Local MMAL camera, it should detect the connected camera automatically, apply your changes and you have your expected output.
Trouble shooting

The PiCam is not connected to the wifi after the steps in Connec the PiCam to your wifi.

If the PiCam was not able to connect to the wifi it will open its hotspot again so reconnect to it and input your settings again.
