Eamon is right, using connectors can weaken the signal for the faster network speed on the System, is it a Cat 5 cable for sure or cat 5 E?? the difference is network speed capabilities, ideally the new systems work better on a cat 6 cable, to deal with the new 5G network speeds, Ive just installed a new Wireless system that works over WIFI, its pretty good with 4G wifi and 1080p HD cameras so no need for POE wiring, crystal clear pictures and video thru an App for my phone and also has a could storage subscription for continuous monitoring if required
