Re: But can the camera recognize approved cats, or not?
I have a ginger and white tom, he gets around and scraps with a couple of the other neighbourhood cats, I also have a chubby white she, who never leaves the terrace, is scared (literally) of her own shadow and is generally timid.
If anything climbs the almond tree to get on to our terrace it is met by a whirlwind of teefenklaus and white fluff, the ginger will usually watch with mild interest. She saw of a grey tabby tomcat that probably had 2 or 3 kilos more weight, nowadays it has a slightly shredded left ear nd gives the almond tree a wide berth.
The only thing I have seen that might do a better job on an intruding cat would be a Jack Russell.
