Get ya point mate. Just to answere your question:

Nope didn't so far. But looked into the prices for personal interest.

The cheap Homesurveilliance stuff - sure cheapest sensors you have seen.

But the expensive stuff? Sensors are actually decent, often coppled with optical zoom.

But none of those are super expensive in the making I believe. The devices promise of delivering and not having any downtime in harsh environments is the relevant price maker.

But tbf the whole area of surveilliance is filled with overpriced shit.

Nonetheless, one that dismantles such appliances would have to pay those stupid prices for compensation. Hence the heads up.
