They just show the new settings in real environment.
Sure they do marketing for them. But when seeing all these videos for new features from manufactures aka marketing videos there are many who shows features which dont work.
You can simply check this watching acupick 2.0 stories videos.
one might think its the same as unifi protect. But there is still no AI integration like unifi, frigate or others already deliver.
Then there are news about software which identify uyghurs in public. Same manufactures. If they have the ability, why not use it in their product line ? Maybe the AI is just some people watching a single camera 24/7. Human AI.
the problem with Dahua is that they have platforms which are much more modern (have much more modern web UI) and have much more inteligent AI analytics.
But they are not offered on cameras (because of limited power) but on dedicated servers with big AI acceleration cards, which can do a lot of AI processing.
Most of those solutions are only available on China market. Or China + some of Asia and some Middle East market. No Western worlds.
Generally in regions where there is no Western policy / rules and agenda against companies from China.
Those solutions are offered for bigger money and they are dedicated for bigger companies, cities and governments.
Dahua have solutions which can recognize millions of humans from database by both face, body analysis from high number of cams in real time. They have very extensive human / vehicle behavior analysis which works in similar configuration.
What we see in western countries are mostly very cut and scaled down solutions done for very limited processing power devices (cameras, NVR) and sold for relatively cheap bucks.
In the high-end side, even highest Dahua products (like those servers below) for western markets are cut down in comparison to full Chinese versions...
but yes - from our (end users in western worlds) point of view, it doesn't matter at all. We evaluate what is available to us.
