So I recently bought sjcam4000 Air wifi, and tried to use it on a vacation. Kinda disappointing. Though i know it has limited features, you can barely use it because the sjcamzone app does not support this model. I can't see this model's details as well here on the site. Practically does not exist on this site. So to others who already bought this model, how did you do? What app did you use? Any tips and tricks?
