Appendix IV: Commands for system integrations
- http://N.N.N.N/tmp/snap.jpg
The
http://[IPcam_IP]/tmp/snap.jpg
command is to retrieve for the 640x480 image which is
generated by the cameras at the speed of one image per second. The quality of such image
should look good to you too, although it is only VGA.

http://N.N.N.N/cgi-bin/admin/snapshot.cgi
You may use " http://[IPcam_IP]/cgi-bin/admin/snapshot.cgi " CGI command to get 1600x1200
images. We recommend not to send this command to camera too frequently, because such CGI
command will ask the camera to send out immediate 2megapixel image, while too frequent
CGI commands would definitely make the camera unstable, because frequent CGI commands
like that have not been expected in its existing codes.
Both kinds of commands mentioned above are different. The http://[IPcam_IP]/tmp/snap.jpg will
not cause too much loading to the cameras, because such 1fps VGA image has already been there
already, but the " http://[IPcam_IP]/cgi-bin/admin/snapshot.cgi " CGI command will ask camera to
do a lots of works that it will cause heavier loads to the cameras.
