Hi good day,
I read about your project and I would love to participate in, I can make your web application, for webcams system.
I wonder, if you can use some framework ?, I think that would be a good choice drupal, I can do the functions you need and make it responsive to mobile devices.
I have over 10 years of experience developing PHP, MySQL and Drupal.
I know well html5, css3, js, jquery, bootstrap.
We can talk more about your project.
