you can mount pretty much anything on the ceiling if you want! ;-)
i think the question refers to whether the image can be rotated accordingly if you mount the beamer upside down on the existing camera connection with 1/4 inch thread:
yes, you can. however, a lateral deviation/distortion cannot be corrected.
This device is not good at all. To have a good quality, you have to pay the price and buy a more expensive camera (between 500.- and 1000.-). You have to choose a higher resolution...
We bought this projector for its "portable" aspect, but we immediately returned it when we saw the poor quality of the image...
it is possible via wifi or with the charging cable i have already done both! unfortunately i don't know how to do it anymore either! search youtube there you will find the answer
I use this device for indoor training on the exercise bike. It should be quite dark, and I don't think the colour reproduction is that great. But it's enough for my needs. For your purpose, I would probably buy something more powerful.
Hello
I have only connected the device for pictures so far, and I was able to use the wifi for that. The connection process is a bit unusual, but very reliable. According to the description, the device has an internal speaker, but no Bluetooth. I wouldn't expect that much from the small speaker anyway. Therefore, it is better to output the sound via a separate, good Bluetooth device.
