Hello, Yesterday I received my first 3 cameras and PoE switch, and went on to fire them up and configure them after work. I got two 2122, one with 2.8mm lens, the other 4mm lens and black housing. From what I understand both are the same save for the lens and color, but I noticed that the LED arrays and lenses look very different from each other. Is this because of the 2.8 vs 4mm lens or somehow they are different products? I managed to upgrade both to the latest firmware.
