Thank you very much for your reply. You have a very good point re: 24/7 recording.
Follow-up question, please:
Where is the best place to purchase the Dahua NVR in the US?
Also, I have considered getting a packaged system from s e c c @ m k i n g, that uses dahua hardware/software....but am hesitant for fear of locking myself into their app.... Don't want to be at their mercy if they decide not to support the next version of iOS or Safari. Any suggestions on that?
Thanks again. I really appreciate you taking the time to reply.
