Hello everyone, I'm looking to install a new IP CCTV system for a warehouse with a showroom. I think I've decided on: 4x 12mp 360deg fisheye cameras 3 or 4x 3mp dome cameras NVR capable of handling 360 degree and all of the cameras- IC Realtime NVR-8128 or Dahua DH-NVR616DR-128-4K The reason I was thinking about IC Realtime is because I have a good friend that sells and installs these into high-end clients and has never had a problem. He is also willing to sell it to me near cost. 40-45% off MSRP. Same with labor which is also huge. Thanks to CCTV Forum I realized that IC Realtime is re-branded Dahua. I import from real manufactures for a living so I understand the values of US support and guaranteed quality. I'm also familiar how manufactures sell low quality products in the same housings through different avenues like Costco, Amazon, and unauthorized people that sell over DX or Aliexpress, ect. -Does anyone know of any Dahua authorized distributors in the US? -Is the software identical on the NVRs from IC Realtime and Dahua? -Does anyone know for sure if the new 4k 12mp 360deg. cameras are interchangeable between the two manufactures? Thanks in advance, alqpoe
