I've purchased one sricam SP006/SP007. Sp006 comes with memory card which I can insert and record accordingly. However, for SP007, there's no memory card and I can't record at all. Anyone tried to mod their own CCTV and install memory on it? I would love to know if it's possible and will do it myself if required. I can only live view and there's no recording nor storage information. Appreciate any assistance tendered.
