I own a bunch of
these cameras. Made by Reolink, they do not require a computer. You only need a computer for recording. You can access the camera directly through a web browser, you just need to know the IP Address of the camera.
Setup is simple. If you have a smartphone, all you need to do is connect the camera to your network and then scan the bar code on the bottom of the camera. Otherwise, just find the IP address through the router and connect to it through your web browser. I have mine setup and connected to a laptop because I record the footage.
