Thought I'd throw in my 2cents worth since I am familiar with them.
We use March at a large educational (K12) customer with over 8k cameras recording on their system. We don't use any of their cameras but only because we had already set a standard with Axis. I cannot complain at all about their service, reliability, or end user experience. All have exceeded expectations. We average under <1% of cameras down/unavailable on any given school day. Usually as a result of a network issue that is quickly resolved. Other than replacing an occasional HD, we have very little problems with our March recording platform.
I've been nervous about their acquisition but can't see any negative impact. Glad to hear that their financials are stable. Sure that they want more growth but I, at least, am just happy that they are still here and still working.
