Do you support security cameras?

How in depth is your support for your surveillance system? Do you just give your security vendor a vlan and call it a day, do you share support for the recording and management servers, or are you all in house now?

Way before my time everything was separate. The security cams had it's own physical network. Then we sourced a server with our MSP and shared some support between vendor and MSP but it got messy. Now I'm trying to just give our security vendor their vlan and let them do their thing. The only thing we're responsible now is the network. Everything else is on security vendor.

Am I making a mistake?
