I've been looking at upgrading the camera on the fc40. I started to look at the sj4000 for a cheaper option. I came across the Wi-Fi version being released on the 27th. I know there are a lot of fakes of this camera made and one of the fakes works off of 2.4ghz. If the real one is running off of 2.4 will this work without any interference? If there is a problem I will probably just get the non Wi-Fi and Velcro the fc40 camera on the front if I needed it.
