My impression has always been that they are kind of a commercial DIY oriented retail store, with some self branded NVRs. I have driven past their location for years, but never heard their name in the context of any project I have been involved in professionally.
Since you asked, whose ‘ignorance’ are they talking about?
All of the devices in the warehouse will be upgraded properly by us or by our local partners. Our online upgrading system will do its job, and we expect your attention in case of failure due to ignorance or other reasons.
"We recently found 3 vulnerabilities with a great help from 3rd party security expert. 2 of them are deeply inside the firmware, and can be used to control the devices, or even damage the info or devices if professional know-how is there. We seriously ask for a update of firmware in proper way to block the vulnerability, in order to avoid the possible risk in the future."
I guess they pay as much attention to grammar, punctuation as they did on their bug ridden firmware.
A few contradictions, least alone trying to save their face!
