I made 3 cables for my IP camera using this cable. Those 30 feet or less work well. The one at 60 feet doesn't work. I cannot connect to the camera because the connection quality is very poor. When I ping it I only get 25-50% responses. No it's not a camera because I tried two different cameras and they behaved the same. So do not buy this cable if you plan to use a long network cable. Update 6/5/19 Updated to 5 stars. I found out why the 60ft cable wasn't working. I mistakenly used only half of the green wire for mains and half for DC. Therefore there was too much noise in the network and therefore half of the pings were missing. I started with an orange/green twisted pair for Ethernet and a brown/blue twisted pair for power, and my IP camera worked fine.
