JackOfAllTrades 0 Posted January 31, 2012 Getting ready to install a CCTV system and I am going to have the power and video signal go through a Cat5 cable. My questions: - Does the cable need to be shielded if it is passing around CFL lighting in a hotel? - What is the difference between Cat5 and Cat5e? - I read about some bad Cat5 cables being made in China that fall apart and have poor wiring inside of them. Where can I buy QUALITY cables at? THANKS! Share this post Link to post Share on other sites
Soundy 1 Posted January 31, 2012 - Does the cable need to be shielded if it is passing around CFL lighting in a hotel? No. - What is the difference between Cat5 and Cat5e? http://www.connectworld.net/syscon/support.htm 1. What is the difference between CAT-5, CAT-5e, CAT-6, CAT-7... The Simple Answer: CAT-5 is rated to 100M CAT-5e is rated to 350M CAT-6 and CAT6e is rated to 550M or 1000M depending on your source CAT-7 is supposedly rated to 700M or presumably 1000M Today there is no approved CAT-6 or CAT-7. While some folks are selling products they call Level 6 or 7, there aren't even specs for them, making CAT-5e the best available option. CAT-6 cable is being made with 23 guage conductor wire as opposed to the slightly smaller 24 guage for CAT-5e and also has a separator to handle crosstalk better. Both CAT-5 and CAT-5e 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, attenuation, and NEXT. 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 CAT-5e cable instead of CAT-5. CAT-5e is formally called ANSI/TIA/EIA 568A-5 or simply Cat-5e (the e stands for 'enhanced'). CAT-5e is completely backward compatible with current CAT-5 equipment. The enhanced electrical performance of CAT-5e ensures that the cable will support applications that require additional bandwidth, such as gigabit Ethernet or analog video.

wetteddy 0 Posted April 8, 2012 I use belden shielded cat 5 or cat 5e cable, depending on the distance. Cut your own cable lengths and forget about the cheap china made stuff. You will be happier in the long run. Share this post Link to post Share on other sites
