Its also to help police with investigations. POE cameras and doorbells won’t have this specific weakness, they’ll probably still get in and steal all your valuables, but if they think thier wifi jammer is working you might get some footage thats useful for the cops…
But then if they do realise you’ve got POE devices I guess they could use a laser to overheat the external cameras I guess, or nock out your power if you don’t have them on a UPS…
