Comparing two different cameras from the same manufacturer, I'm having trouble understanding sensor size in relation to megapixels. Camera 1 is a 4 MP, 1/3" CMOS, and 20 fps, and camera 2 is a 5 MP, 1/2.8" CMOS, and 30 fps. If I understand correctly, the higher the megapixels the more light is needed at night. Since the CMOS is about the same size, will the 5 MP perform better during the day and the 4 MP perform better at night?

Hi OSU
In terms of sensor size .. 1/2.8" vs 1/3" is significant
there will also be aspect ratio when looking at a 4MP vs 5MP camera.
There's a lot more to this, as there is also sensor technology ( " quality " ) and generation of sensor chip also, as well as the supporting chips and firmware, as well as the Lens, and f-stop, .. since it get's complex quickly we often just point out the sensor size is important to consider.
Most 1/3" sensors are not well liked by members here.
Both of them would be poor choices.
1/3 sensor is good for 720P, not 4MP
1/2.8 sensor is good for 2MP, not 5MP.
The 5MP would probably beat the 4MP on the 1/3 sensor, but it would still be a bad choice.
You want a camera in green.
See this thread for the commonly recommended cameras (along with Amazon links) based on distance to IDENTIFY that represent the overall best value in terms of price and performance day and night.
