Some time ago, to think of a closed circuit television (CCTV) and the installation of security cameras (either analog or IP cameras), as we see at the Bank or at the highways was not for everyone because of its high cost.
Today it is possible to have total control of our assets with the installation of security cameras at very low prices, even when not physically present in the place, we can control the surveillance cameras from almost any device with internet access (PC, Notebook, Netbook, Ipad, Iphone, Tablets, Android phones, etc, etc)
