Abstract—Over the years an increasing demand for an
automated security system begins to emerge. Many applications
that help in protecting life and properties are being developed.
Most of them are aimed at improving the work of security
personnel and security agencies. However, security is a
responsibility of everyone not only the security agencies or
security personnel alone. This paper present an interactive
security monitoring system based on passive infrared motion
detection sensor, which will capture the image of any intruding
persons and share it to the entire people that are using the
system on both Android platform and in an online portal
display. The people on the system can communicate with each
other and post information to a commonly accessible board in
the online system to discuss any issues or to see if anyone
recognizes the felons/intruder on the images. Images of interest
can then be transmitted to law enforcement authorities. This
could be use in anywhere that needs to be protected against
intruder. It will be best use in kindergarten, primary school and
or in a neighborhood. That is why we call it neighborhood
watch security system (NWSS). Preliminaries evaluation
indicated an accurate image captured in a real time with an
avoidance of false alarm.
