When it comes to security camera systems for the home, office or facilities, the replacement of older analog camera systems with digital ones has been a slow process for a number of reasons.The most obvious reason is the expense as you are not just replacing the security cameras and recording units, but also the coax cable as well. Plus, there will need to be amplifiers and other supporting equipment in order to get the clearer digital signal.
However, there is a relatively new system that allows you to keep the old coax cables while upgrading the cameras and recording equipment to HD quality. This new system costs less than other digital models(HD SDI ,HD CVI etc ) and carries the promise of
being the affordable solution. The HD TVI security camera system is one that is garnering a considerable amount of attention for
good reason.
