samsung smo-151qn
That's what I was given

Now, I would ASSUME that is inclusive of everything, cameras and receiver - but not necessarily, they bought it used from someone. It was mentioned to me that it said Class A Receiver on it, or something along those lines. Have any thoughts regarding the system? I'm currently googling it, etc.
Thanks.
Edit: It looks to me like they want to use the computer to record the data from the cameras? Does this make sense?
