Hey everyone! I have an existing 26 camera coax system with Dahua NVR covering 3 structures and around 15,000 SF -- it's around 6-7 years old and some of the cameras are dying. I am thinking about replacing all of the coax wires with ethernet, and replacing the NVR with a computer with Blue Iris.
1) Do you guys think it's worth the "upgrade", or just replace a few of the dying cameras and all of them as they die? Coax doesn't have all of the new features that IPCAMS do (smart tracking, facial recog, etc) and I feel like my coax system is harder to troubleshoot--sometimes the power cables get chewed by rats, sometimes coax, a couple of times, the power supply burnt out, etc.
My concerns were initially regarding bandwidth and distance for the POE runs. with about 26 4MP cams, I did some research and I think the max bnadwidth is about 26MB/S, so if I run all the cams on a separate gigabit LAN I think I should be ok.
2) Can I just use a POE switch for this second lan or do I need a router? Also, I would need two networks running to the computer I guess, one for the POE LAN, and one for the main WAN/LAN network.
3) I guess I was also thinking of just getting another POE Dahua or Amcrest NVR but don't like getting locked into particular branded cameras and also don't particularly like the third party interface/apps (DMSS/GDMSS/etc)
Love this forum, and look forward to being active on it, and thanks for all of your help!
