A Video Balun is a good choice for long cable runs. Use CAT5 or CAT6 cable to transmit video signals up to1000ft. Save time and money utilizing unused cable already installed in your home or place of business. CAT5/CAT6 cable is capable of transmitting video signals at much grater distances then standard composite video cable without degrading signal quality. This professional grade unit is great for video surveillance.
Another advantage of transmitting video over Cat5 cable is that you have multiple pairs of wires. Typically you have 4 pairs of 22 gauge wire in a Cat5E cable, so you can use one Cat5E cable for 4 security cameras.
