Sorry, Camect does not replace your arlo base station.
There's no way for your camera to work without the Arlo base. What Camect does is provide a way to record the video and get high-quality alerts once you have a fully functioning Arlo camera.
If you're going to have to buy a base and you only have one camera, you may want to consider whether it would make more sense to just buy a regular wifi IP camera instead ... It will probably be cheaper, and won't depend on Arlo's servers to work.
