Say you are behind the times also you don’t believe it, so now you know, I heard a friend said, although said to be some not happy, but he wanted to say are justified ah, if it were not for yourself too outdated. How could I even the marine CCTV did not know it, to feel oneself still really should be the friend to learn about it. Today I am free with nothing, and friends go out shopping, we go to an electronics store, we see the marine CCTV, then see this time, I asked my friend this is what, at that time, a friend said to me, but he later told the me a lot knowledge regarding the marine CCTV. Now I think I have some understanding of the marine CCTV, and then later saw the marine CCTV. I also know is what, also know how to use.
