Hi Soundy,
thanks for the comments. However, I'm asking only about analog board cameras...
Of course, megapixel or IP cameras are better quality. Hey, I could use a Canon 5d mk2 and get even better quality. But the fact is, I am "stuck" with analog board cameras. For this project, I can only use those, primarily because of the cost, and especially the size (38 x 38 mm and only about 5mm deep)
thanks,
Flyeye
