Hi,
here is a project which tracks movement at room level rather than the tracking of an individual person.
It uses a graphical user interface in the form of a Windows Form Programmed with C.
When motion is detected, each sensor displays when motion was detected and if it is still ongoing. When it has finally finished, for each individual sensor, it shows when it has ended in that room / zone.
A sensor log records everything in a text box and can be saved to a Notepad.txt file before closing the program for review.
Simple setup of the Arduino, breadboard and 2 PIR sensors (have also tried this with 3 PIR sensors and works but was reconfiguring a few things when took this picture) sorry quality is bad on my smart phone camera:

Here is a very short video of what happens when movement is detected or I wave my hand in front of each of the sensors. Each sensors is wired in parallel so when one is in a HIGH state, the other sensor can also go HIGH at anytime movement is detected, or not:

The square blocks can also be replaced with an exact blue print and floor layout of the rooms they are monitoring. This is just a prototype to make sure it works.
The program is designed in a way within the Windows Form that any sensor really can be put in place of the PIR sensor such as flame detectors and smoke detectors which could help fire investigators, from the log, find out which room or area the fire started in first much quicker to name but one other use.
Any views, thoughts or ideas would be greatly appreciated.
