Hello, 
I have problem to capture snapshot. 
  
I am using the following model: 
Device TypeIPC-HFW1120RM 
Software Version2.420.0000.4.R, build : 2015-04-17 
WEB Version3.2.1.262736 
ONVIF Version2.4.1 
  
I am using the following command to capture a image: 
http://192.168.1.108/cgi-bin/snapshot.cgi?chn=1&u=admin&p=[mypassword] 
  
Problem: 
1.It still asks for username password pop-up even though i am supplying the credentials. (check screenshot) 
2. After manual authentication, snapshot works sometimes, but refreshing the page or using the same URL repeatedly stops giving out fresh snapshot. 
  
Please help.
