Wow! That's an amazing rant for a large organisation to put on their public website in such a high-profile way.
They are clearly feeling pricked by the articles.
An Internet search for negative and inaccurate reports about Hikvision will yield one source: the online scribe’s “articles.”
It looks like ipcamtalk needs to up their SEO activities.
Though, to be fair, the negative comments in ipcamtalk are mostly about their detested region-locking tactics, and black-and-white technical support.
I just had an excellent response from Hikvision technical support in the UK.
I'd bought a used 7604NI-E1/4P/A NVR cheap from eBay, so I can experiment with the firmware without disruption. It was apparently an Amazon customer return, according to the eBay seller.
It turned out it had a failed Seagate OEM Barracuda ES.2 HDD with a 5 year warranty still valid. I emailed the Hikvision 'Authorised Distributor' that Hikvision EU identified for me. They passed me on to Hikvision UK Technical Support, who immediately replaced the HDD with a proper Seagate Skyhawk HDD without requiring return of the failed drive or evidence of the failure.
I was well chuffed!
