I have a couple cats and one of the little aholes is pissing outside the litter box.. trying to figure out which one it is so I want to setup a security camera with motion sensing that can connect to my PC to do all the recording. Does anything like this exist? It will need to be wireless for network but I do have plugs available for the power. Thx for any help.. this has been going on long enough and it could be a medical problem one is having.
