Create a stand to hold the camera and Adjust it in the direction you want to monitor.
Open the terminal and type the following commands: "cd ~/Desktop/Physical-Computing-Face-Recognition-master" and then "python livedetection.py".
The last command you typed in runs the image recognition program. This will show you which image is currently processed and where it detected a face.
You will find a csv file in the same folder as the livedetection.py file.
This csv file contains one row for each time a face has been detected. The row contains a time stamp and the number of face detected.
Final comment. In the current setup the program was developed so that no pictures of the visitors are taken to ensure the privacy of patients and their visitors.
Possible tweaks for this setup are: Creating a cron-job which starts the program if it is currently not running, Store images to ensure only people are visiting that are allowed to.
