The Hikvision DS-2CD2742FWD-IS IP camera is a high quality camera. With the last firmware update, the administration panel is no longer compatible with modern browsers like Chrome or FireFox. There is still a way to get the video stream from these browsers via the Hikvision proprietary protocol ISAPI.
In the following, we assume
The first command allows the user to get a snapshot. The camera sent a JPG image to the browser:
HTTP without authentification
http://<IP of the camera>:<HTTP port>/ISAPI/Streaming/channels/1/picture
HTTP with authentification
http://<username>:<password>@<IP of the camera>:<HTTP port>/ISAPI/Streaming/channels/1/picture
This command returns a 4 mega pixels image (resolution = 2688 x 1520 pixels). Here is an example of snapshoot:
Same snapshot by night:
The second command is for getting live video stream. The camera sent a h.264 stream to the browser:
HTTP without authentification
http://<IP of the camera>:<HTTP port>/ISAPI/Streaming/channels/102/httpPreview
HTTP with authentification
http://<username>:<password>@<IP of the camera>:<HTTP port>/ISAPI/Streaming/channels/102/httpPreview
This command returns a 640x360 live stream. Unfortunatly, this is the maximum resolution I was able to get, and probably the best resolution we can get in a browser.
