Authentication Error

[damodaran]

I am getting the following error when I tried to run the example code given in the github.
Please find the details given below:

$ node ipnode.js 
Connected to 192.168.20.244:80

      ^

The code:

var     ipcamera	= require('node-hikvision-api');

// Options:
var options = {
    host	: '192.168.20.244',
    port 	: '80',
    user 	: 'admin',
    pass 	: '1234qwer',
    log 	: true,
};

var hikvision 	= new ipcamera.hikvision(options);

Please let me know what went wrong?

I'm getting the same error. Any ideas?

I was getting the same error. But after I realized that node-hikvision-api uses digest/basic authentication method. Then as you can see below, I changed the authentication method from digest to digest/basic.

If your error still persists you can use given below code for tracking alarms as I do. This code is taken from node-hikvision-api and I changed it slightly.

any patches? I have seen this api being used for node-red and it just crashes the entire service once this happens? Ideas how to fix it? my camera is set to digest/basic, onvif and cgi enabled

I get the same error, could you solve that problem?

Hello,

This issue was related to xml2js library as far as I remember. I did some adjustments to previously shared code but at this moment I could not remember. However, I can make a detailed explanation next week.
