Many people, such as myself, decide to invest in home security camera systems.  Most of them nowadays allow you connect directly to the system via your smartphone.   As I am in the computer security field, I tend to wonder just how secure things are in my own home.  So I put my NiteOwl 16 channel DVR system to the Pepsi challenge.  It failed horribly.
