That ban is crazy government thinking they are eliminating the potential of hacking by the Chinese government without addressing the real issue.
Hacking vulnerabilities are the same regardless of who makes the cameras...or any IoT for that matter...and that is why most of us here isolate our cameras from the internet...it's just irony that they are surveillance cameras...it flows better saying security cameras are not very secure but many here do not consider them security cameras as they are for surveillance!
And our wonderful government decided to ban Hikvision and Dahua from government installations due to being partly owned by the Chinese government and the potential to be hacked...yet fail to recognize the real problem are the cameras can be breached and then they get exploited with other manufacturer cameras because they failed to isolate them from the internet. End result is people/governments that shouldn't see the camera feeds are now seeing them...
Yep, instead of our government forbidding public agencies from using Chinese brand cameras like Dahua and Hikvision because they could be used to be spied on by the Chinese government, they should have been looking at what the real issue is, and it is this issue that will be same regardless of who makes a camera. You need to get the cameras off the internet period.
We have already seen countless examples where governments facilities that installed expensive AXIS cameras that are built in the US were hacked into....
Keep your cameras off the internet, regardless of who makes it, is the best thing you can do.
