douza 0 Posted December 30, 2015 Hi, I have a DVR8-4100 Swann DVR with on RJ45 port on the back. Can I add 2x PTZ cameras to this with it only having one of those ports? Thanks, Phil Share this post Link to post Share on other sites
phillipscctv 0 Posted January 2, 2016 The RJ45 on the back of your DVR is NOT for PTZ connection. It is for network connection only. Connect your PTZ data to RS485(A & B). Yes you can connect 2 or more PTZ's to your DVR. Give us more information about the model of your PTZ's. It maybe a IP PTZ's and it's not compatible with your analog DVR. Good Luck!
