Is edge camera worth buying?

Hi guys, what I do is to buy security products from big companies and sell them to get margin.

However recently because of covid19, we have fewer customers.But the suppliers hope we can buy some more equipments for stocking.

And they’re talking about the AI edge cameras, they said it’s the trend. It doesn’t need a NVR or server to run CCTV system.
However the price is higher, which I think is not attractive to my customers.

Does anyone also sell edge cameras successfully recently? It is worth buying?
