Travis Chaffin

Travis Chaffin – Sales Manager – 2M CCTV 877-926-2288 x 6049   CCTV is closely associated with other aspects of the IT world.  In fact, most of the time, it is the IT pros that are assigned with learning about, choosing, ordering, and installing the systems.  I get asked a lot about the difference between Cat5, Cat5e, and Cat6 when customers are looking to buy cable for a CCTV system.  Cat 6 cable is better.  It is newer technology, it is faster, and 6 is higher than 5.  If they were the same price, always buy Cat…
