Hello - Just built my PiDog and everything works great… except… the camera. I believe my camera is not being recognized. I’m not sure how to troubleshoot or resolve the issue. From this [other similar post](https://forum.sunfounder.com/t/pidog-camera-appears-to-not-work-no-idea-how-to-test/1574/2) here is my info: 1.Raspberry Pi camera is properly connected and oriented correctly? I believe so. Pictures attached below 2.What version of the operating system are you currently using? Debian GNU/Linux 12 (bookworm) 3.Please run libcamera-hello to test if the camera is working This is what I get: ```auto ~/pidog/examples $ sudo libcamera-hello [0:39:57.420566437] [2624] INFO Camera camera_manager.cpp:325 libcamera v0.3.2+99-1230f78d error: XDG_RUNTIME_DIR is invalid or not set in the environment. Made X/EGL preview window ERROR: ***no cameras available*** ``` 4.When you run the example code, if there are any errors, please provide a complete screenshot of the error for us to analyze and resolve the issue. ```auto ~/pidog/examples $ sudo python3 7_face_track.py vilib 0.3.12 launching ... picamera2 0.3.24 config_file: /home/brian/.config/pidog/pidog.conf robot_hat init ... done imu_sh3001 init ... done rgb_strip init ... done dual_touch init ... done sound_direction init ... done sound_effect init ... pinctrl set 20 op dh done ultrasonic init ... done Imgshow start ...

I’m not sure but I take a look to the tutorial video on YouTube and I think you install cable to camera upside-down. Look at the blue side need to face the black clip on rpi board and on camera board. ![Screenshot_20250130_182913_Chrome](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/2X/3/396ef7d11ec75106b2670980fa58f87a3081e378.jpeg) ![Screenshot_20250130_183150_Chrome](https://canada1.discourse-cdn.com/flex029/uploads/sunfounder/original/2X/1/1b0355e42efd3b6610e1b387f99578a8d71d2bb1.jpeg) ---

Hi @Weirdyguy - first, thanks for responding so quickly! Second, you are correct. I now switched the cable orientation into the camera (but not from the Raspberry Pi), and the camera is now recognized and works. Thanks! I was fooled by the instruction sheet, which shows NO twist to the cable as it runs from the RPi to the camera. But indeed it needs one twist to change orientation. Awesome, thank you! ---

I notice that the cable ending with 90° go connect to camera and the flat ending goes to rpi. If you take a look at the video tutorial. [https://docs.sunfounder.com/projects/pidog/en/latest/assemble\_video.html](https://docs.sunfounder.com/projects/pidog/en/latest/assemble_video.html) Second video at 1:43 and third video at 10:30. Have fun! 😉
