AD / Tyco "markets" Video Edge / Victor to what is left of the Intellex customer base as the backward compatible product solution to view those legacy DVRs along with new IP installs with a single client. They have been trying to get it right for a long time but realized the erosion of that legacy base is so substantial that they couldn't rely solely on that hook
The problem as already noted is Video Edge is clunky, expensive and doesn't play well with other HW so the need to fill that gap became evident a few years ago and they entered into the OEM with Exacq. The majority of sales were the HVR and NVR boxes. It was simple set up and deployment.
Many of their customers however wanted to supply their own COTS servers so the necessity to have a SW solution pushed them to acquire Exacq. what's interesting is even with that product in their portfolio we see the Tyco strategic account sales group leading with other VMS in certain strategic accounts
