I believe the components are just rebranded Dahua cameras and NVR. The cameras are QCN7005B and the NVR is QC814. It's being sold as 4CH NVR but I believe it is an 8CH NVR but only 4 POE ports. The camera is the updated version of QCN7001B which in turn is a Dahua IPC-HFW2100 so it should be able to do 1280x960 (1.3MP) at 15fps and 1280x720 at 30fps. Focal length is 3.6mm. NVR is probably the same as Dahua NVR3104-P/NVR3108-P. System comes with 4 100ft Cat5 cables too. It would cost more to just buy 4 cameras separately at $130 which is the lowest I've seen the Dahua camera goes for. I bought two systems and should receive it tomorrow. Standard shipping is also free and only $10 extra for overnight to California.

Does an NVR simply save the stream or does it re-encode the footage again using whatever codec it can handle. I see many screenshots of the Dahua NVR and it lets you specify the bitrate, frame rate, resolution, etc. for each channel. I'm assuming that it is re-encoding the stream to according to those settings. I really want to avoid the NVR from encoding again a stream that's already highly compressed by the camera. My cameras are Vivotek IP8332 and they have been tested to work with ONVIF software. I use it with Vivotek's own server software(ST7501). The camera has 4 streams and the server can "record" from any stream. It saves the stream directly onto the hard drive in .3gp format. I want to use a standalone NVR to record from my cameras as I don't want to leave my power draining server up 24/7 just to record.
