Ive been around the block and tried a lot of NVRs. Blue Iris is truly the most affordable one Ive encountered, and its performance is outstanding and reliable. I used to hesitate to check in on my old NVR using the iOS client, but Blue Iris had given me such great confidence that now I cant help but check in multiple times a day. Priced at $50/year for the server and $10 per mobile client, I worry the developer isnt charging enough. Whoever you are, Sir, you are indeed a charitable soul. Blue Iris allows up to 64 surveillance cameras per server, supports h.264, supports SSL, and provides intelligent storage options for your recordings. I know the UI may not appeal to a younger crowd, but what it lacks in appearance it more than makes up for its incredibly deep feature set and thoughtful, smart choices in default settings.
