I bought same second camera that I already have C560WS and installed in the wall and working perfectly and I opened another same camera but when I tried tapo app and add device but the device isnt connecting at all, I can see only red and green light every repeat. I tried factory reset device but didn't work, I unplugged first camera to see if  working, but no luck. But when I plugged the ethernet cable and its working but we prefer wifi, and when setup is complete and is asking to change to wifi but it says no network available, I tried manually and still no available.

What im guessing is Tapo device wifi fault and only ethernet cable works?
