Review on 500ft Pure Copper Cat6 Bulk Cable - Outdoor/Indoor Heat Resistant, Solid, 550Mhz, 23AWG, Riser Rated CMR, Blue by Mikey Jackson

I bought it to run Cat6 drops around the house. I ended up putting 1 in each bedroom (3) and 1 in the living room. Then I started 2 surveillance cameras outside and the cable is dead. I don't know if I got to 500 feet exactly or if my math was terrible. Good cables, I don't have much experience with other brands. I will be buying another box as I need to finish the other 2 cameras! I will update the review if I notice signal degradation over time.
