You are asking for a lot of specific things that are not readily available in handy wrapped packages…
-
Camera. There is no official list or “perfect” camera. You simply try what you have and play around with the URL layout. Relatively recent changes do seem to allow some mjpeg based as well as RTSP, but you should simply keep reading the forum posts and experimenting for yourself.
-
Servo control for camera positioning. This isn’t even close to being Blynk specific and if you haven’t yet learned how to move a servo in Blynk with some code, servo library and control widgets, then again, please start searching, reading and learning.
-
Commercial site for camera. Honestly, just Google for IP cameras… they are all over the place. And even a few good links have been shared in this forum.
Sorry if you don’t appreciate my “accent”, it is not intended to be critical or rude, but you have been a member for almost a year and still keep asking for things to be handed to you, that you could easily find on your own with a simple Google search and some quality reading time in this forum.
