Don't get me wrong, I agree with most of the concerns or criticisms of some of the closed systems, those are real risks. My point was to answer the questions of the gap in understanding as to why users rate/value those systems differently than integrators do. And on the flip side, I have personally dealt with small security companies that have gone out of business and left their bespoke systems to be ripped out and replaced far sooner than they should have because no one else was willing to support them.
This change in the market represents a potential disruption to the current dominate model if it isn't challenged head on in features and user experience. Snark and dismissing the trend will not lead to good results. This trend of integrated, simpler systems eating more of the market has played out over and over during my lifetime alone. A good example may be phone systems, where hosted phone systems have largely become the default choice for the majority of the business market. Yes there will be many on-prem phone systems installed for certain environments, but there is no denying the market has shifted. The good news in the Cloud phone system world is many of the providers are utilizing open standards based phones, often made by others. However that fact is almost never considered by customers when choosing between Mitel (with their proprietary phones) and someone like Ring Central and Yealink SIP phones. The Customer is much more concerned about features, reliability, support and cost. And of course phone system ISVs/VARs are still present, but their focus and their own sense of what their "product" is has shifted.
The problem is SIP actually existed long before the emergence of the hosted phone system market and was able to be built on for a more open platform standard. However even in the SIP world there always has been challenges of trying to use different SIP devices with different PBX systems, "Standards" aren't always so standard.
It important to understand that disruptions usually occur because of a convergence of technology evolution (and sometimes breakthroughs) along with business model innovations. What's enabling these camera services in question is a combination of improvements with solid state storage, edge processing power, cloud storage costs and the increasing availability of plentiful (or at least sufficient) WAN bandwidth.
Take this to heart and create an alternative! Where is the version of ONVIF that allows for open platform cloud services with integrated provisioning and management? I don't think there is a technological issue preventing this from happening, it's building a standard that (as always) is the real challenge.
But if you don't understand why your own product may not be valued quite so highly by your customers and you don't understand the appeal of competing products.. Well don't be surprised if you start identifying with the likes of Blackberry or Palm.
