Your experience matches mine. I don't think you're doing anything wrong. I tried to get it to detect wildlife (deer and other smaller animals) and it only detected them when they were fairly close to the camera. I don't know the precise distance, but it seemed if they were more than 30' away or so they weren't detected. I was using the wireless outdoor camera and I moved the camera as far away from the base station as I could to get better results.
I've now moved it to a different residence and it doesn't detect people walking by at about 20 to 30' away, but I have it in a window, so I don't know if that affects things.
