The most important of feature of any home security system is to detect the people who enter or leave the house.
Instead of monitoring that through passwords or pins unique faces can be made use of as they are one’s biometric trait.
These are innate and cannot be modified or stolen easily. The level of security can be raised by using face detection.
Whenever the person comes in front of the door, it recognizes the face and if it is registered then it unlocks the door, if the face is not registered it will raise an alarm and clicks a picture (MMS) and send it on the registered number.
