I used a Hikvision NVR and 2 Hikvision 2CD2032 bullets, 2 Longsee Low Light Destroyers, and 2 Dahua 4431s for a couple of years. I finally read the blue iris forum long enough to get the courage to build a blue iris system. I am really happy that I did. I followed the advise from this forum and purchased the refurbished i7-4770 Win-10. I sold some of the old cams and added 4 of the much praised HDW5231R-Z from Andy. I liked them so much that I ordered 4 more today. I have to say I am impressed with all the knowledge and advise on here. After tweaking the program, my CPU usage is 27% with the 6 cameras recording to disc. I will check out the rest of the great videos by Dasstrum and get some email alerts set up to my cell. I am really pleased with my setup and Thank everyone for this EXCELLENT information. Merry Christmas to all.
