The wifi range is limited to about 20 metres and reduces further when walls and doors are in the way. When the camera drops out, which is frequent, you need to manually sinc again which painful if you are away and remotely monitoring. Most times when syncing you need to restart the base station and then you need to take down and sync all the cameras again. Ive done this so many times in the first two weeks Ive given up and just taken all the cameras down.
