The SJCAM SJ4000 is a multipurpose action camera which can record video at 1080p x 30 FPS and take photographs. It is also water-resistant up to 30m when used with housing. It is action-packed with lots of additional gadgets. Camera has been released in two variants : Non WiFi WiFi version There is no need to mention that the only difference between the two is built in WiFi. I will clarify why you might or might not need a WiFi.

But I assure you everything said here applies to non WiFi variant as well.
