HD-TVI security cameras can record high definition footage from 1.3mp to 2mp. They come in a variety of styles, from dome and bullet to PTZ surveillance options. TVI is a popular new technology that provides high definition video surveillance using standard coaxial cable. These security cameras are a great choice for users looking to upgrade their outdated analog systems because they are affordable and use much of the same cabling as analog systems. The resolution of these cameras even rivals that of many IP cameras. Get the best products for your money with HD-TVI surveillance cameras from WorldEyeCam.
