Simple Baby Monitor

It requires 2 or more Apple iOS devices: iPhone, iPad, iPod Touch. One will be "Baby device" where the cry detector transmits alerts to the "Parent device". If the parent wants, the "Baby device" can stream Audio, Video or both from the "Baby device".
The connection between devices is made through WiFi or BlueTooth automatically. You still need to add a security key on the parent device for confidentiality reasons.
