Question: Names of the IVS configurations

[goermezer]

Hi,

very cool script. It runs very stable for me in a docker container and sends the events from my Dahua IPC cameras to HomeAssistant. Is it possible to get the names for the configured lines and regions through MQTT? I would like to know, from which configured region or line the detected events come.

Ok, I had to read a bit better:

CameraEvents/IVS/Garage CrossLineDetection With Human in RightToLeft direction for Gate region

It seems, that the region should be delivered. But I never got a message like this. I only find CrossLineDetection in the payload. I miss the part "With Human in RightToLeft direction for Gate region".

This is what the logs write:

Code=CrossRegionDetection;action=Start;index=0 2020-02-13 06:31:42,875 - main - ERROR - Error getting IVS data: 'data' 2020-02-13 06:31:42,876 - main - INFO - Snapshot Url: http://192.168.178.90:80/cgi-bin/snapshot.cgi?channel=1 2020-02-13 06:31:43,402 - main - ERROR - Error sending image: ('Connection aborted.', BadStatusLine("''",)) 2020-02-13 06:31:45,192 - main - DEBUG - [Dahua3]: --myboundary

Some of this depends on the device doimg the sending. If you pull the logs and look for the detection event, I believe I dump the entire json string to the log. If its not json, your device might only trigger the alert, but not post the metadara.

Here is a full json alert where the rule is posted:

}

If you don't get this out and only see:

--myboundary
Content-Type: text/plain
Content-Length:1078

Code=CrossRegionDetection;action=Stop;index=1

Then I can't gather the rule area.

I`m not sure whether my cams support that events, but I find a lot of information in /cgi-bin/configManager.cgi?action=getConfig&name=VideoAnalyseRule.

And I changed VideoAnalyseRule[0][0].Enable and VideoAnalyseRule[0][0].AlarmOutEnable to true by HTTP request.

When running CameraEvents, it shows:

Code=CrossRegionDetection;action=Start;index=0 2020-02-14 17:30:00,338 - main - ERROR - Error getting IVS data: 'data' 2020-02-14 17:30:00,340 - main - INFO - Snapshot Url: http://192.168.178.90:80/cgi-bin/snapshot.cgi?channel=0 2020-02-14 17:30:00,542 - main - ERROR - Error sending image: ('Connection aborted.', BadStatusLine("''",)) 2020-02-14 17:30:00,642 - main - DEBUG - [Dahua3]: --myboundary Content-Type: text/plain Content-Length:46

The image sometimes can not be downloaded because of timeouts. I live with it for the moment. But do you have an idea how I can find out if this should be supported?

[psyciknz]

It doesn’t look like you get the json data like my example. I don’t know from what firmware version that started.

Does http://192.168.178.90/cgi-bin/snapshot.cgi?channel=0. Work from a browser?

If this a camera or nvr? As in is there a channel=1?

[goermezer]

It is a camera, IPC-HDW4631C-A with System Version 2.460.GP01.16.R, Build Date: 2017-09-04.

http://192.168.178.90/cgi-bin/snapshot.cgi?channel=0 delivers an image as well as with channel=1.

[goermezer]

It seems that IPC-HDW4631C-A doesn`t provide these information. Closing the issue...
