How to connect camera to Raspberry Pi at 15 meters?

Question

Do it yourself

I would like to put some small camera on the stairwell. And the raspberry itself, due to certain circumstances, should be in the apartment. From the meta placement of the camera to the distribution of about 15 meters.
What can be done in this case? How to reach the camera?
The official Raspberry Pi Camera Module is very good in size (just what you need), but is not designed for such a data transfer distance.

Or does the only option remain robocraft.ru/blog/projects/3219.html ?
UPD: on Amazon in the comments I found such a solution https://www.tindie.com/products/freto/pi-camera-hd...
maybe someone assembled such a unit or knows where you can order only such converters?)

Answer 1

Buy an IP camera, or better a Wi-Fi camera. This is the simplest option.

Answer 2

well, either hang raspberries in the entrance along with the camera, or buy a separate whole ip-camera, then you don’t need raspberries

Answer 3

Perhaps EasyCap USB video capture adapter + analog camera with 15 meter cable will do. But I haven't tried it, check it out.
