I really want to get all the functionality of the the Tp Link tapo phone software using the TP-Link Tapo C520WS Outdoor Pan and Tilt camera. This is free software with no subscription. But I want to us a VIGI camera because I want a POE camera. I have existing POE switch and camera's but the TP link Vigi is much more features. Can I use these cameras as standalone with recording on a micro-sd and using a phone app to get notifications? I don't want to pay subscription fee's and I like the TP Tapo features
