CAT5e is better than CAT5. CAT5 cable works fine on most resolutions (Component Video) in excess of 500 feet. However, in order to future proof the system, CAT6 (HDMI) would be a worthy investment. It has lower loss, more bandwidth, and less time delay skew than CAT5. These are very desirable in a video system. Both CAT-5 and CAT5e have 100 ohm impedance and electrical characteristics supporting transmissions up to 100 MHz . The differences between CAT-5 and CAT-5E show in all aspects of performance: capacitance, frequency, resistance, and attenuation. CAT-5E components were designed with high-speed gigabit Ethernet in mind. While CAT-5 components may function to some degree in a gigabit Ethernet, they perform below standard during high-data transfer scenarios. CAT-5e cables work with ATM and gigabit speed products. Simply, if you are using a 100Mbps switch, get CAT5e cable instead of CAT-5, especially for HDMI audio/video.
