HTTP (CGI) exposure commands doesn't work

[Raczey]

Hello everybody,

I'm trying to change manually exposure parameters using HTTP commands, I get "OK" response, but I see no reaction in the video (I watch online video via RTSP).
Also I've tried to change any other video parameters (like flip, rotate) and it doesn't change anything also.

Here some commands I've tried:
172.24.1.1:8080/cgi-bin/configManager.cgi?action=setConfig&VideoInOptions[0].Mirror=true
172.24.1.1:8080/cgi-bin/configManager.cgi?action=setConfig&VideoInOptions[0].Mirror=false
172.24.1.1:8080/cgi-bin/configManager.cgi?action=setConfig&VideoInOptions[0].ExposureMode=4&VideoInOptions[0].ExposureSpeed=1&VideoInOptions[0].GainMin=0&VideoInOptions[0].GainMax=1&VideoInOptions[0].ExposureValue1=1&VideoInOptions[0].ExposureValue2=2

I watch RTSP signal using this address: rtsp:/admin:*@172.24.1.1:554/cam/realmonitor?channel=1&subtype=0

Also I cannot watch channel=0. Maybe it is a problem? But also when I put "VideoInOptions[1]" in http commands - I get: "Error Bad Request!".

Do anyone has any idea what is the reason?

Camera model is DH-SD22204T-GN
Firmware (newest): 2.622.0000000.3.R, Build Date: 2018-01-16

Best regards,
Tom

I've figured it out. There are many versions of HTTP API instruction and not all of commands from the newest one are working. Very unfriendly chaos.
