They have already been selling compromised devices and no one cares...they just claim it was an accidental back door.....now, these devices should be isolated on networks but they are simply using extreme caution...
Being smart about security is as much about responding to threats as it is reducing the possibility of a threat. We don't know what we don't know. Also remember that this is China we are talking about. The government controls everything to some extent or another. Companies don't have the protections we do here. Not that we are perfect
If the Chinese government wanted Hikvision, or Dahua, to implement back doors they would probably have no choice. I imagine the same might apply in the US as well however I would hope it's less an issue of coercion and threat than agreement and cooperation.Dunno, you could certainly leak a very low res stills in something like an update query to the mothership or a time sync. So many possibilities that look innocuous.
Certainly you could do things to prevent a leak... but is there a chance that something might happen to allow a leak to occur anyway? A firewall change that shouldn't have happened. A phishing attack that drops a piece of middlewhere somewhere that allows video to leak out. For the normal joe it's probably not a big risk but for the military the question becomes why take the risk at all?
