Kalip 0 Posted April 6, 2019 When installing a camera, is it necessary to use all 3 pairs of remain wires in cat5e cable for the power supply as shown in this diagram? Share this post Link to post Share on other sites
tomcctv 190 Posted April 6, 2019 Hi. The more you can use for power the better .... if not adding another camera to the same cat5 1 cam use 1 pair for video other 3 for power 2 cam use 2 pair for video other 2 for power Share this post Link to post Share on other sites
clementsj 0 Posted June 11, 2019 The only thing I would change is how you have the remaining pairs hooked up for power. You have all of the solid colors going to positive and the others to negative. The pairs are twisted together so you have the positive and negative wrapped around each other which could lead to power drops and other issues. Just use 2 of the remaining pairs and keep the like colors together. I would use green/greenwhite for positive and brown/brownwhite for negative. Leave the orange/orangewhite unused. Still getting 2 solid core wires per connection and safer in the long run. Share this post Link to post Share on other sites
