Didn't you answer your own question? :)
Lenel Video is horrible. Just truly horrible. It's not just that it doesn't have "advanced functionality," it's that it doesn't have "basic functionality" either. The list of supported cameras is minimal and seems to be shrinking with every new release, the compression they have to use to be able to handle the video causes significant quality issues compared to a Genetec or Avigilon that can handle large amounts of video without compression, and the search functions are truly putrid, to the point where any company that does even semi-frequent investigations, I can almost generate an ROI calculation off of their video searches alone and how long it takes them to review, consolidate, and export video.
I have said this before and will say it again (much to the chagrin of manufacturers on both sides) -- I have yet to see an access control manufacturer produce a truly top-tier video product, and I have yet to see a video manufacturer produce a truly top-tier access control product. Lenel has it's issues and frustrations, but as an access control platform, there is a reason they are where they are in the access control pecking order (same with CCure, same with S2). Similarly, Genetec isn't perfect on the video side, but their product is so far superior to Lenel Video that it's almost painful to discuss once you've worked on both of them. Unfortunately, Lenel sucks at video, and while Genetec doesn't suck at access control, it's nowhere near a top-tier product...yet. Maybe it will be. But not right now.
I have no hope for Lenel video though. Lenel clearly threw that out as a "oh hey, we can do that too" type thing, and have never developed it. Prism is awful too.
