Go into the Cameradar repository, create a directory named `build` +3. In the build directory, run `cmake ..` This will generate the Makefiles you need to build Cameradar +4.

More information will be given about the configuration file in another part of this document. +7. You are now ready to launch Cameradar by launching `./cameradar` in the cameradar_standalone directory. + +### Configuration + +Here is the basic content of the configuration file with simple placeholders : +```json +{ + "subnets" : "SUBNET1,SUBNET2,SUBNET3,[...]", + "ports" : "PORT1,PORT2,[...]", + "rtsp_url_file" : "conf/url.json", + "rtsp_ids_file" : "conf/ids.json", + "thumbnail_storage_path" : "/valid/path/to/a/storage/directory", + "cache_manager_path" : "../cache_managers/dumb_cache_manager", + "cache_manager_name" : "dumb" +} +``` + +The subnetworks should be passed separated by commas only, and their subnet format should be the same as used in nmap. +```json +"subnets" : "172.100.16.0/24,172.100.17.0/24,localhost,192.168.1.13" +``` + +The **RTSP ports for most cameras are 554**, so you should probably specify 554 as one of the ports you scan. Not giving any ports in the configuration will scan every port of every host found on the subnetworks..How is formatted Cameradar's result +You **can use your own files for the ids and routes dictionaries** used to bruteforce the cameras, but the Cameradar repo already gives you a good base that works with most cameras. + +The thumbnail storage path should be a **valid and accessible directory** in which the thumbnails will be stored. + +The cache manager path and name variables are used to change the cache manager you want to load into Cameradar. If you want to, you can code your own cache manager using a database, a file, a remote server, [...].
