I realised I didn't post this here.
So these are the timelapse footages I shot with my SJCam SJ4000 Wifi version.
I love the results, the wide angle, and the fact that it's HD. And yes, I'm lazy to manually shoot the whole time lapse thing, so with the SJCam, I can just leave the camera there and do my stuff or just sit beside it and just relax. Although there's apps for timelapse video for both iPhone and Android phone, but I think it's battery consuming, and while I'm shooting time lapse, I can't do other stuff with my phone, so this is definitely a very good alternative!
