Hi all, you have a very informative forum which I learnt a lot from. I need an advice on a surveillance network we are asked to build. I am actually a System Analyst and I have a good background in networking but I lack experience when it comes to selecting a good reliable NVR. The goal is installing 100+ analogue cameras plus as much microphones in a 4 stories building where they all will be connected to a central monitoring room. I have seen many NVRs online (not many supporting analogue cameras and audio inputs) but my concerns are reliability and video management features. Requirements: - 100+ channels analogue video and audio (can be more than one NVR, 3- 64 channels maybe). - simultaneous recording, and viewing on network clients. (can be web interface or desktop software). - has to be reliable, supports continuous operation 24/7. - better if it is an international brand (Sony, Samsung, Panasonic, JVC ... etc) for support and warranty. - has to provide a straight forward method to export video/audio footage to external storage devices (Flash/DVD/external HD). sorry for the long post, I hope you can help. regards, Nasser
