I personally want to say no, but the more scientific part of my brain will only let me vote don't know. I think "yes" is extremely unlikely, though.
What is lacking in this poll is the intent. I absolutely believe the engineers who designed the product can figure out how to get into the product.
I believe the real question and if it's worthy of a conspiracy theory, is "Why do you think they have a back door"
a. Customer Service
b. Evil purposes
yes for sure i was in china recently and all the system integrators met said yes. the present govt monitors everything I was told. Also this was stated by them a few months ago I think one of their executives announced this in a press conference
Sub-question: Do they ever actually USE it?
I find it hard to believe that some boffin hasn't pulled the whole code apart and found it, should it exist not to mention that should it get out that there's one there, the entire company collapses.
I'm voting "Don't know" but leaning towards "no"
well, Cisco switches did,
Juniper too, (an un-intentional one apparently)
there's probably a "zero day" flaw in the cameras that few know about....
Actually though, why bother with back doors when most of the target market leave passwords and user names at default allowing a lot of cameras to become DDOS originators or for NVR's to become bitcoin miners !
