These are three fully working indoor cameras by YI. They pan and tilt and record to microsd cards (not included). They have motion detection including pan and tilt and infra red for night time. The YI smartphone app to view content has very intrusive and annoying advertising to persuade you to buy one of their cloud plans so I have replaced these with Tapo cameras hence these are available. I have an additional camera that works but no longer pans and tilts. With power connectors and fixing plates.
Say why you want these. May split but prefer them to all go at the same time. I used them to monitor my pets when away for the day.
