If someone really have safety wifi cam... It's would be just natural selection. BTW cam have only one purpose, alerting. 99% of the time having evidence is useless, as a deterrence it's almost the same. They are effective only to alert a distant owner "something is happening in your property" and IF wired and well disposed get a chance to see what's wrong an instant before the shiny system die. Marginally they are requested for some insurances, at least to lower their price.
