events not working

[ljubomirb]

I tried with node 6.10, 8.0, 8.1.
I'm not sure if it's related to camera (some clone from china), since I can see events in its manager (some internet explorer activex plugin), but... if someone else also has this problem, then there might be something here to explore...

var CAMERA_HOST = '192.168.1.10',
    USERNAME = 'admin',
    PASSWORD = '',
    PORT = 8899;

var http = require('http'),
    Cam = require('onvif').Cam;

new Cam({
    hostname: CAMERA_HOST,
    username: USERNAME,
    password: PASSWORD,
    port: PORT
}, function(err) {
    if (err) {
        console.log('Connection Failed');
        return;
    }
    console.log('CONNECTED');   
    this.on('event', function(camMessage) { console.log(camMessage) });

});

Error: You should create pull-point subscription first!

and when I remove require ('http') (wich should not be a problem), then error changes to:

Have you tried with latest from Github? I'm now getting Error: socket hang up from pullMessages in (events.js) after adding a log for err.

I'm testing with a Reolink RLC-410. Trying to find consistent documentation. I'm seeing examples that say wsa:To must be specified, as well as other formats. New to onvif so still have some more digging to do.

I see the same error:

Error: You should create pull-point subscription first!

Which seems to stem from the createPullPointSubscription() call in events.js which going back further gives an error from the request made, in my case:

ONVIF SOAP Fault: Argument Value Invalid

On my Hikvision gear at least. If I look at the actual request, I'm not sure what is invalid. There certainly isn't much in the body and the rest appears to mainly be auth boilerplate:

Will continue to dig a bit..

Hi James (@Codelica),
Have you ever found a solution for the pull-point subscription error?
Thanks !!
Bart

[Codelica]

@bartbutenaers I'm afraid I didn't. Had to move on with some other projects, so this was left on the "someday" list :) Sorry...

Event subscribing is something I'm trying to figure out as well. Why it has to be so complicated?

[ozett]

someone who fixed/improved onvif-event handling may kindly state this here on this thered?
i subscribe now and wait for update...
👍

I have rewritten parts of the events code and it works nicely with Hikvision and Axis equipment.
The new code handles the missing wsa:To field in the XML and subscribes to the pull point first.
Example6.js gives a simple demo.

So I will close this issue report as we have now code for events. Please raise a new report if you still have problems.
Thanks
