We have a site with a bunch of old IQEye MJPEG cameras and a few analog cameras. We need to replace the failing DVR and the separate system driving the paypoint and customer awareness monitors, but the site's ownership will be changing hands at some point in the near future, and because the current ownership doesn't want to hand them a nice new expensive system (that they'll probably rip out to replace with their own stuff anyway), we're trying to come up with a lower-cost temporary alternative.
The problem is finding anything in a low-cost NVR that will work with MJPEG cameras. Ideally we'd need something with a multi-screen spot output to drive a paypoint monitor; a separate encoder can still be used for the analog cameras if a hybrid/tribrid isn't available. MJPEG is the stumbling block (and no, they won't be amenable to swapping out all the cameras, either).
