Problem with downloading image from BCS camera

[buuuudzik]

I have some problem with downloading image from BCS cameras.

In older BCS camers such linked worked very well:
http://IP/cgi-bin/snapshot.cgi?chn=2&u=USER&p=PASS

I am using such links which worked very well with older BCS cameras:
Link1: http://IP/cgi-bin/snapshot.cgi?chn=2&u=USER&p=PASS
Link2: http://USER:PASS@IP/cgi-bin/snapshot.cgi?chn=2
Link3: http://USER:PASS@IP/cgi-bin/snapshot.cgi?chn=2&u=USER&p=PASS

When I try download image then I have an error 401 (Not authorized)
local image, err = socket.http.request(link)

Link 2 and 3 works fine in browser.

How can I solve this?
