extracting snapshot or video with http for lorex camera

Does anyone know how to get a snapshot from a lorex IP cam? I'm using these cameras with my nvr:

With some of the hikvision stuff you used to be able to do something along these lines:

 

http:// -ip address- /Streaming/channels/1/picture

 

-or-

 

https:// -ip address- /Streaming/channels/1/picture

 

I'd like to know if anyone knows how to do something similar with these lorex cams I'm using

AND....I figured it out. It's actually through my nvr, which is an LNR632. It's the following:

 

http://IPADDRESS/cgi-bin/snapshot.cgi?1

 

The only thing I'm unclear is how to select the channel I want to take picture of. I thought the last digit was the channel. But when I change it, it just keeps taking picture of channel 1.

 

Any ideas?
