Now every one is holding a cellphone, 3G or 4G(more G will be I guess), which makes live broadcast possible, and brings personalized home security system into spotlight. Many manufacturers have already took actions to launch smart IPC for home users. The real pickle for home security is not technology, but how the end users feel about using it. You need mobile app and IP camera to get your home surveillance. Not every user can handle this smoothly, even a simple gateway setting can stand in way.
Anyway I can still smell potential in it, With all this mobile games and apps, adding a surveillance apk will not hurt . Only a matter of simplifying the user part and arousing consciousness.
