Design a system to make a house with equipments, which communicate with you while you are away, on your mobile. Here are the examples of some of the operations it may perform.
· If any visitor presses the doorbell, you receive a sms /mms / call with his photo, instantly.
· Any unwanted intruder into the house gets his photo mms'ed to your mobile.
· While being away, you can communicate to the security alarm in your house (through cell phone) to activate itself in case of danger.
· Sms your electricity equipments to turn on or off by themselves when you are away.
· It sends you an sms, whenever your loved ones reach home etc.
