„ We designed a secure webWe designed a secure web-connected security -connected security

system that, when alarm

system that, when alarm--triggered, allows the triggered, allows the monitoring person/company to remotely conduct monitoring person/company to remotely conduct

a video and audio surveillance of the property. To a video and audio surveillance of the property. To

guard against misuse and protect the privacy of guard against misuse and protect the privacy of the property occupants, the system is triggered the property occupants, the system is triggered only when an alarm is set by an intruder. When only when an alarm is set by an intruder. When triggered, the system transmits real time audio triggered, the system transmits real time audio and video feeds via the web from cameras and and video feeds via the web from cameras and

microphones installed on the property. The microphones installed on the property. The

monitoring company/person can see and hear monitoring company/person can see and hear

what's going on inside the property and can what's going on inside the property and can

direct the proper authorities depending on the direct the proper authorities depending on the situation. The system was prototyped for less situation. The system was prototyped for less

than $400 and was successfully tested and shown than $400 and was successfully tested and shown

to be secure and reliable. to be secure and reliable.
