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.

Doesn’t install and if it’s showing a camera then the message is: connection overload. Can’t use either of these 2 cameras. Purchased 2 cameras, but can’t install them 🥺. Don’t recommend!

The app works fine, it could have all the advertisements removed.

I was able to place a camera, power it up and connected to my home Wi-Fi. This app made it all simple to do.

The only problem I’m experiencing is the quality of video, but that is not the app’s fault it’s the china quality camera I decided to use.
