Can you watch this video and let me know if this is typical quality to expect?

I bought this camera system:

http://www.monoprice.com/Product?c_id=110&cp_id=11019&cs_id=1101901&p_id=9888&seq=1&format=2

It says the cameras have 1/4" Sharp 420TVL CCD

I have 1 of the cameras sitting in our kitchen looking through a single pane window and made this video.

Does the quality look like what I should expect?  It's pretty disappointing.  In the viewing app, there's 3 choices for video quality: Best, Fine, Normal    I have it set to best.

And for resolution, the choices are CIF, HD1, D1.  I had it set to CIF.  I think that was the problem?  Should I choose D1?  But is the camera D1 quality?  Like recording a VHS tape at HD quality - the recording will take more space, but bad input will just give you bad output at larger file size?

You should choose D1 if you want high resolution

CIF (352 x 240)
HD1 (704 x 240)
D1 (704 x 480)

However this affects your fps (frames per second).  If you get 200 fps with CIF, you'll only get 100 fps with HD1 and 50 fps with D1.

You'll have to test and see what you get.

that d1 setting is for recording.  but would you know how 470TVL correlates to the cif / HD1 / D1 setting?  I know something like 320 is real grainy.  Recording 320 at some higher resolution is (almost?) pointless?  Back to the idea that the file will be bigger and no improvement in the image?

The 420TVL lens is considered a poor lens.  The 420TV describes the resolution of the lens.  See http://en.wikipedia.org/wiki/Television_lines

Roughly it has a 420 (will be a little bit greater than 420) by 420 resolution.  That's adequate for CIF but inadequate for D1.
