Project has been delayed a bit as I ordered the wrong camera (RS232 instead of TTL... doh). If you are doing this project yourself, get the TTL one as it's easier for Arduino. Rather than spend more money on mine I will probably just use a MAX232 to convert it.

Also the TLG10UA03 is drawing way too much power for my liking. I'll either to switch to using a NXP nrf24l01+ radio with a base station at the other end to bridge it to my home ethernet network or I could even add the electricImp... but this does add a lot of extra complexity and cost - so might just try the NRF for now.
