just like cloud storage, most customers do not have the necessary upload bandwidth to facilitate cloud analytics. There are also too many ISP factors involved... such as routing and distance from customer to central station. i doubt customers will want to purchase an internet line dedicated just to security.
i would much rather pay for a license one time and be done with it than pay monthly.
all my customers are 5mbps up or better and even the ones that have higher speeds, it takes forever to remotely pull video for them and I have never seen their upload between their site and my office go above 2-3mbps, and i run a gigabit fiber.
so with that said, i think theres factors beyond central station and customer control.
i say 100-200kbps because ive looked at my 2nd stream live bandwidths and that is what they hover around.
But AgentVI is running an agent / app on the camera doing pre-processing, so your 2nd stream bandwidth is not applicable. AgentVI may be wrong about 50kb/s requirement but your checking a live 2nd stream does not relate to the approach they are taking.
I'm not familiar with this specific product, although I intend to find out more. As an employee of Eagle Eye Networks (a cloud based VMS) I hear about bandwidth on a daily basis. I agree that not all areas or all customers are a good fit for Cloud. However, there are a lot of businesses that are a potential fit. If you look at Cloud in general - outside the video surveillance industry - it has enabled powerful applications to be delivered to companies that might not have deployed them otherwise (i.e. CRM - SalesForce.com, Data Storage/Sharing - Dropbox.com, Phone Systems - RingCentral.com) Obviously these applications are not a fit for all businesses either, but the have plenty of customers - and they are moving upmarket to larger companies (http://www.salesforce.com/customers/)
I'm very aware of the unique demands video places on the network, but I also see those limitations being overcome with increased network capacity and new technologies and new techniques. Cloud is making it's way into every aspect of business applications, video surveillance and video analytics are certainly included on that journey.
