The pan/tilt function is used to point the camera inside every now and again ( to look at a home PC that i often use with remote desktop - too see if its working OK ) and to look down a new path every now and again ( been a few issues) to cover it all i would be looking at three cameras
I currently have a Vstar cam https://www.amazon.co.uk/gp/product/B01DU9PQ8S/ref=oh_aui_search_asin_title?ie=UTF8&psc=1
that works OK ish, however
Every now and again it re-boots /crashes with a horrible screech sound coming from the speaker
Video captured is supposed to be HD 1280x720 However...
