This is an even-numbered year, so I think Cisco will claim participation in the security market this year.
1, do you mean an existing VSOM install? If so, do you know what version it is? My understanding is that version 7 was completely redone and removed the old Broadware / bad approach, related: Cisco Reboots Video Surveillance
Btw, as for the Cisco cameras, rarely are they used outside of with Cisco VMS / VSOM. The cameras just have little competitive advantage and are quite expensive so not much justification to use with other VMSes. Related, if you were to switch to another VMS, I would worry about support / integration of those older Cisco cameras with third party VMSes. (Related Cisco claims some of their cameras support ONVIF, but Cisco is not listed as an ONVIF member but have some older conformance).
The cameras, 6020, 6030 have a rather high failure rate, also they go dark and need rebooting to correct.
A number of years ago, i asked the Cisco rep how we could integrate his VMS with the access control system. He gave me a "per door price" of several thousands of dollars each. Anyone hear of this before?
I have seen and used VSOM version 7.7. It is decent but not to the level of other well known enterprise VMS. Version 7 came out within the last year I believe and has made a big difference in performance, at least I am told as much from some of my colleagues that dealt with previous versions. I know that Cisco is trying to make a push internally to get their product out on market but it isn't being received very well due to the bad history of the product. Regarding playing well with access control, I have only seen it used with CPAM (Cisco physical access manager) and their components. I don't know how well it will play with other access control systems (I wouldn't bet that it would be an easy integration). Lastly with the cameras, I am fairly positive they OEM their cameras but I can't get a confirmation on this. If you look around their communities site, there are some posts pointing to another manufacturer for their mounting accessories. I have also heard from other engineers that this is the case. I agree with a previous post that I would be cautious of using them on any VMS other than Ciscos.
