Trigger alarm by CURL

[TheDude69]

Hello Community,

I have got a HIK DS-2CD2622FWD-IS camera. There is an alarm defined that triggers a mechanism to open and close a gate. This works fine so far when using the HIK Vison iVMS4200 client. But what I like to do ist to open and close the gate by a batch file using CURL.

I can do the following:
curl.exe -T test.xml http://user:pwd@ip-address:80/ISAPI/SYSTEM/IO/outputs/1/trigger

The content of the xml file is the following:
<IOPortData version="2.0" xmlns="http://www.isapi.org/ver20/XMLSchema">
<outputState>low</outputState>
</IOPortData>

When doing this I receive:
<?xml version="1.0" encoding="UTF-8"?>
<ResponseStatus version="2.0" xmlns="http://www.hikvision.com/ver20/XMLSchema">
<requestURL>/ISAPI/SYSTEM/IO/outputs/1/trigger</requestURL>
<statusCode>1</statusCode>
<statusString>OK</statusString>
<subStatusCode>ok</subStatusCode>
</ResponseStatus>

But from here I do not know how to do the next step. Here is a screenshot showing the configuration in the camera:



Has anyone an idea what I have to put into the xml file to open and close the gate?

Many thanks in advance,
best regards

I'm keen to follow your progress with this. I have no experience with what you are attempting but does anything happen when you change the outputState to high in your test.xml?
<outputState>high</outputState>

Just a thought, have you tried using the ONVIF Test Tool? It provides detailed diagnostics and step details.

Hi StewartM,

... got it. The mistake was only to send a high or a low. But sending a high follwed by a low starts the alarm and obviousley resets the channel. Now it is perfect.

Thank you very much!

Best regards
