EVERY camera has security issues. It is why most of us here isolate cameras from the internet. If you don't use P2P and UPnP, no reason for the cameras need to install any other programs on your system. My Dahua's have not installed any other programs to work and I completely set them up on a computer that does not have internet access before I install them on my system.
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 NDAA compliant were hacked into...
And of course other camera companies are now going to try to use this ban to their advantage, but as a consumer, you need to decide what marketing nonsense to believe and which one to pass on.
Regardless of who makes the camera, it should be limited in its ability to reach the internet. So at that point, go with the camera that is going to give you the best chance of a good capture.
