Ok, I am new and have been looking over a few posts and the wiki. So here is my question. Should I have both a dedicated night/day camera. Currently I have 2 8mp cameras with a third waiting on cooler weather to run the network cable in the attic(Florida). I'm thinking of adding 2mp for night time? Is that about right? It was mentioned that 8mp cameras are not the best for night capture. Not that it won't do the job, but rather better image quality. Thanks for any feedback.
