What is your software running on? Since you mention a straight software play, I imagine it would run on the customers 'available' machine?
I don't think many integrators are going to want to support your software running on 'any old customer machine'... there are too many uncontrolled variables that could easily suck a lot of the margins out of any RMR.
Also, I think most integrator sales orgs are not structured in your favor. Lots of integrator company owners love the idea of the additional RMR with a software only play - but few (being generous; I don't know of any) have ever figured out how to get their sales orgs to sell both styles at the same time.
Which, imo, is the problem that your company - and all the other VSaaS plays before you - has with finding traditional security integrators to sling your stuff.
Finally, there are other barriers like bandwidth limitations/costs, free VMS software like Milestone Go, Blue Iris and others, and even dirt cheap surveillance 'kits; etc that can make monthly, per-camera payments less attractive.
"If yes, what do you think the reasonable price per camera per month should be(for local recording)?"
What do you mean by local recording?
