Backend for CleverDog cloud CCTV
Back in 2017, I wrote a report on reverse engineering a WiFi camera of dubious quality (see https://eriknl.github.io/reverse-engineering/2017/09/07/WiFi-camera.html for the full story). After concluding this thing was certainly not safe to use with its default cloud backend I created a proof of concept implementation of the protocols involved and managed to convert the video stream into a standard RTSP stream. From this proof of concept I then created this somewhat cleaner code base and I have been using this ever since to use the camera. In the years since then I have had some people asking me to help them with their own devices, I hope this repository is useful to those that want to try and recreate the backend and have fun with their cameras.
Please understand this software is just a proof of concept and I am putting this out there with no guarantees it will even work for your device or for more recent firmware versions.
Since this application has to run 24/7 make sure to clone the repository to the device you will be running it off of. I have had success with both x86_64 CentOS and a Raspberry Pi 3.
Make sure you have the required build environment, you will need Qt with network support (no gui). Then run qmake and finally build with make.
Since this is application is not a proper forking daemon you will need to create a script to run it through systemd or your init system of choice (on a Raspberry Pi you could start it from /etc/rc.local)
You can scan for cameras in your local network with the -s switch, it will list the IP address of any detected cameras along with their CID. After obtaining a valid CID you can then start streaming it with the -S switch followed by a comma separated list of CIDs.
When running in streaming mode you can access the stream for a given CID with rtsp://<yourhost>:8086/CID=<yourcid>.
