So in short, when plugging in CCTV cameras, avoid wifi and instead keep them on wired ethernet physically and logically segregated from anything that matters. This should already be standard practice. Clearly, the cause is just shitty firmware from vendors. Vendors are just small factory owners who decide to tool up to fabricate 1000s of simple reference design based products by assembling PCBs, cables and plastic enclosures, possibly in cardboard boxes with manuals, and then ship them at cut rates as quickly as possible to as many ends of the earth as will accept them. For vendors, firmware security is low on the priorities list. Their fixed costs, tooling costs, design rebadging overhead and the open reference designs from silicon vendors mean that with minimal value add they will have to produce a vast number of each design very quickly and cheaply in order to have any chance of obtaining a profit in a market essentially guaranteed to have numerous competitors. This misaligned incentive situation will remain the status quo so long as the majority of the market (which is Chinese, not foreign) doesn't practically care about anything other than cost. It is not some evil state conspiracy. If you think there is a market for open source high transparency devices with closed source silicon and driver isolation as a top level design priority, then by all means do a startup.
