General setup instruction for IP cameras
There are two ways to read a jpeg snapshot from an IP camera.  One uses http and the other rtsp.  In both cases you need to know the jpeg snapshot command string for your particular camera.  Just entering the IP address for your camera won’t work.  Camera manufacturers have defined a unique command string for this purpose.

1) Consult your camera user manual
2) Search online for keywords rtsp and your camera model.
3) Consult this amazing camera database

Examples of http and rtsp snapshot command strings –
HIKvision cameras: rtsp://IPADDRESS:554/Streaming/Channels/1
Sharx cameras: http://IPADDRESS/snapshot.jpgrtsp://username:password@IPADDRESS/live/0/h264.sdp

Hanwha Techwin CCTV Camera: rtsp://<DeviceIP>/profile<no>/media.smp
Example: rtsp://
