The security system consists of modules such as security cameras and dynamic sensors. It can monitor the situation at home in all directions and keep danger out of the door. The security camera looks like a small speaker with a 147-degree wide-angle lens on the top. The dynamic sensor can be placed outside the door to report any activitives happening out there. With the facial recognition system, the security camera can let parents know the time their kids return home promptly. A built-in speaker in the middle can emit a 90-decibel alarm to alert everyone in the home of danger.
