So I did a Google search on "car backup cameras ccd vs cmos" - and here is a summary from the first 5 results returned - I specifically took the first 5 results so that people didn't think that I was "cherry picking" results.
I've yet to see ANY article say that a CMOS backup camera will provide better results than a CCD backup camera - not one. I'm not trying to "argue" with anyone about this - just genuinely interested to understand which technology is better suited for a *car backup camera* (again, I think that it's important to research the specific use-case here - what is said about CMOS/CCD handheld cameras may not necessarily apply to car backup cameras, which are MUCH cheaper devices that probably use MUCH lower quality sensors).
Now, I don't know how long ago this stuff was written, but based strictly on what I've read, it still seems that you are generally better off with a CCD backup camera.
I've owned 2 backups cameras so far and both were CMOS/CMD. The new one that I ordered is CCD, so it'll be interesting to see what the difference is, if any. I'll be sure to post my thoughts. I'll also try my best to get both day and night pictures of each (but I am horrible at picture taking - especially when it involves something that is illuminated!).

"CCD Vs Cmos, what backup camera should I get?
The answer to that is “yes, you should upgrade” but let me explain to you why. These questions usually come up through emails or when we take calls over the phone, but it rarely comes up when we’re at trade shows. The reason is, when we are at a show, people get a side by side comparison on a live screen that is hard to show over the internet.*
When the customer comes face to face with the CMOS and CCD they will usually pick the CCD, not because the CMOS is bad but rather the CCD is that good and for the $50 price difference most people would rather splurge and get the best."

"The sensor
Most rear-view cameras either use CCD or CMOS sensors. The sensors convert light to signal in two different ways: CCD is essentially analog, and CMOS is digital. Generally speaking, a CMOS sensor draws less power and is better in low light than a CCD sensor, but a CCD sensor is slightly better adapted to handle fluctuating lighting scenarios than a CMOS sensor. Depending on the types of environments where you typically drive, the difference may be incidental. In the good ol' tradition of iPhone® vs. Android™, the argument as to which sensor is "better" is ever-evolving and has devotees on either side. In most cases, it won't likely be a deciding factor in which camera you choose."

"Image Sensors
Rear view camera sensors are either CCD or CMOS. CCD sensors provide a much higher quality video then CMOS and operate in lower light environments. CCD rear view cameras are more expensive than their CMOS counterparts, but this is truly not the factor where you want to skimp on money. A CCD camera is the only unit to buy."
4. From "http://www.rockyamericas.com/usa/choose_Rear_View_Camera.html"
"Summary of important features that you MUST consider:
By all means, buy a CCD image sensor camera if you can afford, you will find it is really worth the money, you get the best quality video picture possible with high picture resolution, better vision in low illumination environment, etc."
5. From "http://www.ebay.com/gds/What-is-a-C...erse-parking-camera-/10000000021532474/g.html"
"Basically, there are two different types of rear-view reversing cameras for cars on the market. The first type, called a CCD (Charge Coupled Device) is the more expensive of the two cameras as it uses digital technology and has higher clarity. The second type, the CMOS camera is cheaper because it is mass-produced and uses analogue technology.
The CMD sensor, therefore, produces a better image than a standard CMOS sensor, but both of these sensors are inferior to the CCD sensor, which uses digital technology.*"
The second one (Crutchfield) is a little strange becuase it says the exact opposite of everyone else - it states that CMOS is better in low light situations, when all of the others say the exact opposite.
Again, not trying to start an argument here - just providing the results of the re-research that I've done.
