= IP Cameras = The 825 Gen2 includes the wget and curl command line utility and the curl libraries. Most IP cameras provide a URL that can be used to obtain a still image such as a jpeg format file. The wget command line utility may be used to obtain the image such as: {{{ wget 10.1.3.25:/cgi-bin/viewer/video.jpg?resolution=640x480 -O /tmp/img.jpg }}} This could be performed from a system call in an app. A better approach is to use the curl library. Following is an example: {{{ #include "cardinal825.h" #include size_t write_data(void *ptr, size_t size, size_t nmemb, FILE *stream) { size_t written = fwrite(ptr, size, nmemb, stream); return written; } void CaptureImage(int tktNum, const char* code) { char imgfilepath[120]; CURL *curl; FILE *fp; CURLcode res; DEBUG_MSG("%s tktNum %d code [%s]\n", __FUNCTION__, tktNum, code); curl = curl_easy_init(); if(curl) { sprintf_s(imgfilepath, _imgfilefmt, tktNum, code); fp = fopen(imgfilepath, "wb"); curl_easy_setopt(curl, CURLOPT_URL, /*CAMERA_SNAP_URL*/ _cameraSnapURL); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data); curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp); res = curl_easy_perform(curl); if(res != CURLE_OK) { DEBUG_MSG("curl_easy_perform error %d\n", res); } curl_easy_cleanup(curl); fclose(fp); } else { DEBUG_MSG("curl_easy_init returned NULL\n"); } } }}}
