YsxLite 4+

if you follow the on screen instructions they're not very clear. They said to connect to it via Bluetooth, but I couldn't get it to work. The app also says to connect to a directly, which seems to be the best way. The camera has its own hotspot on Wi-Fi which you need to connect to first so the App will proceeded to add the device, then you can go into the settings and input your access point for your home Wi-Fi.
Then you can finally get the camera to connect to your local Wi-Fi network in the app will be able to access it.
The camera's Wi-Fi hotspot will be something like BATA12345AAAA, if that connects you should be able to get it to work, then in the camera settings click they yellow Wi-Fi button and enter your access point & password.
My phone kept disconnecting from the camera and reconnecting to my home network so it kept losing connection, now on my home wifi it seems ok.

I bought two. One worked for a day. The other one doesn’t charge so it has to be plugged in at all times To work. Not very small and having to be plugged in makes it not very incognito . And the motion detection hasn’t worked. The only recording I can get , is if I manually record . Another product that was a waste of money and and waste of my time fiddling around with it.

When the QT code is scanned I’m told it’s invalid. I suspect that it won’t work with an iPhone.
Bought it on Shein and they no longer sell it. The link has magically disappeared. I guess there were too many bad reviews. I looked for videos online for help but I haven’t seen anything helpful
Don’t buy this product. Save your money!
