Why in the world is this encoder so big?

Hi Ethan, if I've got this right, the only advantage of the encoder over a DVR is that the encoder works reliably with third party VMS software systems and the DVR doesn't. Is that right?
If so, I wonder why Dahua wouldn't just enhance their existing DVR's rather than creating an entirely separate line of encoder-only products? It's not like their dedicated encoders are smaller or cheaper than their DVR's! I'm puzzled.

I almost wonder if a Cheap Dahua HD-CVI DVR will also encode to the same equipment as well?

In our comparrison experience - admittedly only a handful -the TVI 4ch DVRs v POE NVR's from the same manufcturer see the DVR's perform better than the NVRs in the responsiveness of the IOS and Android apps. Could this be because of a lower processor load?
I know it seems likely that the anologue HD solutions (TVI in our case) will dominate our lower tier sales through price alone with the benefit of genuinely good performance to boot.
If I was a large legacy brand (Pelco, Vicon?) I'd be jumping all over the encoder idea and assausting the retrofit market.
Opinions?

Hello John,
Do you know if the 16 channel model will also only require 1 Milestone License? Do you have any plans to test the performance of the 16 channel model?
Thank You

What are the lines of resolution after encoding? The Cisco encoders I'm stuck working with are effectively 480.

Anyone have a US based supplier for the Dahua CVI encoders?

Hi Ethan, a quick question :
if Genetec does have a Dahua DVR driver is it fair to assume that driver also supports the DVRs from Dahua ? With all the features ??
That would be cool but i remember in the original article about CVI/TVI that Genetec wouldn't connect to the DVRs ( and only Milestone did ). Is this driver newer ?
Thanks,

I would be eager to see the Hikvision DS-6700-HQHI-SATA tested as well. It's listed as supported on the Exacq site, which is pretty exciting.
