I have nice long been looking for a suitable Action Cam the plus has a good price / performance ratio. After a couple of videos on YouTube and many reviews I decided then for the SJ4000 Wifi. The SJCAM I ordered in December, it was delivered then about 10 days later. Open After I have then first set appropriately, as in a video on YouTube. Unfortunately go Links not hence the name of the video: Qumox / SJCAM SJ4000 Action Camera GoPro // Alternative? Then I SJCAM can test himself and was very surprised how good the image looks like quality, because the videos are converted on Youtube again. A few days later, we went even in the winter holidays, the cam has also taken the same. Back at home the videos were first drawn to because Pc, since the video is saved as the SJ4000 MOV and I wanted to use Windows Movie Maker had the format are converted before in AVI. The result is impressive in my opinion, here the name of the videos on YouTube: SJ4000 WiFi (Full HD) Snowboarding in Winterberg The image quality was by converting a little lost but I'm very satisfied. The SJ4000 WiFi is therefore absolutely worth the money.
