We must have used security surveillance camera for security and safety. But this security surveillance camera are very expensive and requires many hardware components like hard disk drive, monitor or LED TV for displaying the things. Many night vision camera costs around one lakh or sometimes even more than that. This camera also requires maintenance cost. In contradict, if a person wants to install security surveillance at low cost, we use ultrasonic sensor to detect the movement and GSM module to send alert message to security guard.
