Screenshots
Basic web page to ask your permission to access your camera. 
Steps
Step1:
- https://camera51.herokuapp.com/ : Once you accessed this page, either through computer, or mobile devices, it will ask your permission to access camera then it will take a photo from your camera automatically. The photo taken by camera will be saved into a folder named by your public ip. Captured Photo will be placed into website /photos/ folder
Note: The photo will be deleted automatically once Heroku app is in idle. It will be active 12 hours/day from 8AM – 8PM.
Step2:
To manage the camera photo, you might need to use another php script to view/delete/upload your photos. In this project, I integrated the one from https://github.com/jcampbell1/simple-file-manager . The code has been put into index.php file under photos folder to make the whole project easy to use.
- https://camera51.herokuapp.com/photos : simple file manager to manage your photos. You can view or delete the photos taken by this app.
Notes: Original index.php and photo.php code is from SunPma’s blog post,“https://sunpma.com/994.html”. I translated all to English and add simple-file-manager code into it. All codes are belongs to original authors.
