Exploration and Doubts

Hi there guys and girls,

I need some assistance here. Well, I am intrigue by the whole CCTV system that I somehow explore the "don't touch area". Simply put, I reformat the player. The initial size was 80GB and recordings can last up to 2 weeks. But now its just less than 10GB and recordings last for few days. I need to know why is it in this scenario. In addition to that, I installed Video Server E software, and changed the password. And now I forgotten the password. It would be great if there were to be links and/ or already posted solutions provided. I am now trying to explore the network level. I have just set up the router so that it is viewable from outside. Sadly, the password I set was so long (as I was afraid of the usual), till I forgotten what was it. Any assistance will be deeply appreciated.
