There are a lot of different cameras out there. Pick one that fits your rover and has a wireless transmitter attached. If you do a search you'll find tons of different types. As far as using your television, you'll need a 'rf modulator' to convert the signal into someting the tv can use. Don't forget you'll need a reciever as well, they are not included with all cameras..The typical operating range is 2.4 ghz and the range of the signal varies according to price..
