Commercial solution: March Networks (Score 1)

I'm about to get my hands on a few of these NVRs from March Networks. Apparently there are a couple thousand of cameras controlled by these puppies elsewhere in the company. Spoke to a few technical people at March and they seem to know what they are doing. Unrelated to how well the perform, but kind of nice to hear for me as a geek, is that the actual NVR/DVRs are based on an embedded linux distro and can be managed via SSH. Also, they have an Enterprise Security Manager which allows you to authenticate users against external sources like AD, which is nice for an enterprise. I'll be banging on these devices in a couple weeks.
