This is the brand of our company to use Marine CCTV as a work in the company for so many years of my people, for this is a Marine CCTV but quite acceptable, since I came to the company to the company’s old staff said that a Marine CCTV was installed, can be himself the company for so many years, but this is a Marine or CCTV has been so good never seen what quality problems, let alone what appears the problem of a single video even now shoot out and when just bought no big difference, if not see it yourself I really can not believe there will be such a good quality stuff.
