In Surveillance, CCTV Camera Is Costly Because Of The Use Of Computer. It Reserves Too Much Space For Continues Recording And Also Require Manpower To Detect The Unauthorized Activity. But Compared To The Existing System Raspberry Pi System Is Much Cheaper With Better Resolution And Low Power Consumption Feature. Here Pyroelectric Infrared (PIR) Sensors Are Used As A Simple But Powerful People Presence Triggers. This System Is Suitable For Small Personal Area Surveillance. I.e. Personal Office Cabin, Bank Locker Room, Parking Entrance. Whenever The Motion Is Detected Through PIR Sensor Inside The Room The Image Is Captured Through Camera And Temporarily Stored In The Raspberry Pi Module. Internet Of Things Based Application Can Be Used Remotely To View The Activity And Get Notifications When Motion Is Detected.
