Are there any established differences between the various models, such as the model with the best night vision or best night vision distance? It is difficult to not notice some obvious differences between models -- such as the 2CD3332 having one IR illuminator while the 2CD2232 has two IR illuminators and the 2132/2032 have multiple IR LED's as illuminators.
Similarly, are there any known reliability or life-span differences between models?
Thanks
