i think its the same wifi uses on his roomba, but it was around 55 euro's so not that exensive. Seemed more descent then the model i once bought from ebay.
Price is good because of av sender included. is it cmos or ccd? resolution? then i new idea: this cam mounted on roomba means a cam going around your home to control every room. i found this: SPYKEE a robt wifi controlled with software ready to go. just turn it on and use trough internet or internal lan. coming soon on october 2008 (i hope!). it's from MECCANO FRANCE, and it start to work when it detects some movement and recharges itself when batteries going down like roomba.
