CamView

A CLI-tool used to stream CCTV online footage based on URL params


Get Started

To get started with CamView, simply download the camview.py file and download the required libs, and then run.

  1. pip install ast requests selenium climage cv2 multiprocessing argparse
  2. python camview.py

CamView has some optional flags for different modes. To use as normal, you do not need to include any of these. However, for devices with certain constraints, there is an optional CLI mode where images are converted and then printed to the terminal. To use this feature, type:

python camview.py --cli

About CamView

CamView works on part magic, part Python, and part Google! It wouldn't be fair for me to take all the credit, when in fact CamView builds on top of each of these tools.

The process CamView uses is detailed a bit more here for those who are interested.

  1. First, we take the string (either specified by the user or the selected preset) and use it as a Google query like inurl:query. This is a well-known process for finding things on the internet, and used more widely outside of misconfigured/public webcam discovery to find exploitable servers or logins with default credentials. More on this process (called Google Hacking), can be found here
  2. Next, we take all the google search results, and send them to a verify function, where we request the page and check the response. If the page loads as expected, we send the url on, if not, we don't use that url later.
  3. Using the urls we've uncovered, we load each of them and inject a custom JS script into each page. This JS script (since there is no set way to find the stream, as it is an element) will iterate through every image on the site, and then return the one with the largest dimensions. (We go off the assumption that the largest image must be the stream, but ocassionally we are wrong.
  4. Once we have this image in our python script, we open a new thread and display the image using the OpenCV tools, either in the default video player, or we convert the frame with climage and print it as is.
