The Costco system has that 666666 account on the Q-See (Dahua) system also that I couldn't delete. There might be a way to do it if I call support.

You are correct..the camera has to be a native 2mp camera...running a 4mp camera in 2mp mode will not help... Some of the new hikvision 4mp cameras have improved night..not sure about the new dahuas. Thanks for explaining that. After reading about system compatibility among different cameras I think I'm going to use Dahuas for this Q-See system.

Which system are you referring to..

What system did you end up buying..? I got the Q-see system from Costco a few weeks ago. QC8816 with 8 4mp cams. Learned a lot since then.

I'm curious about something you mentioned boogieman......... "The 2mp will perform better in low light." Does that mean if I schedule my Dahua 4mp cams to record at 2mp at night the video will look better...? I'm guessing it's not that simple because it probably depends on the cam itself. Hmm. I've got a lot to learn here.. Any help to straighten the learning curve is appreciated...

I bought a Q-See system from Costco a few weeks back when it was on sale. It has 8 4mp cams (QCN8026B) and NVR QC8816. All the cams are 3.6mm lens so depending on what areas you need to cover you might need different lens. I haven't had any problems other than understanding a few things which were answered by phone or Q-See support. The Q-See system is a rebranded Dahua which is a reputable company. I would strongly suggested using Dahua cams if you add to your system to make things easier to set up. Like Mr. Cyanide said it is a good system for your budget..

Look for a setting where you can set all the cam settings back to default. Just something to try. It helped me out before on a Dahua cam.
