A simple remote camera server. Client can connect to a remote camera and take a snapshot.
It's pretty simple. You connect to it from your browser and press "get snapshot" button. You will be redirected to a page with a new photo on it, and photo's id will be stored in your cookies in case you'll come back.
Both server, client and tests are compatible with python 2 and python 3 now (tested in 2.7.13 and 3.6.0).
First, install all of the requirements either by pip or manually. The only
actual dependency is bottlepy module.
pip install -r pip_requirements.txt
You will need a terminal-based camera app which can receive a filepath
argument. I've used imagesnap for this purpose on OS X. Install it using
homebrew or any other package manager.
Review camera_access.sh and add your app into it. The only argument passed
to the script should be a filepath to an image to be created.
Ensure that server.py and camera_access.sh are both chmod +x and you
have permissions to write into the server + child directories.
You may want to check server config in config.py for such vars as
host/port, secret key, camera "dead time", etc.
Finally, run the server:
server.py
All should work now. Default log record will be stored in server.log. If
you want you can run unit tests executing: python tests.py (they require
your server to be running).
The execution of the script is pretty secure. A client obviously doesn't have access to it, because it's not served in any way, plus in most cases one won't need to exec it with su or sudo, and if you do, then something is wrong with you! Also cookies protection is pretty lame.
Though concurrent connections have been tested, I cannot guarantee high load support.
File names are 7 letter randomly generated strings and, considering that no additional name checks being performed, they may become overwritten eventually (in a couple of centuries).
