I'm pretty much a noob on CCTV, so please bear with me. I have an Axis 240Q Video Server that digitizes composite-analog cameras to MJPEG over IP. I also have a Foscam wireless IP camera. I plan to backfill with IP (probably POE) cameras. What 16 chan NVR(s) can I get that will be able to record all these images? Thanks,
