The 2MP Fixed Bullet is great if you are not needing to zoom in or have a higher resolution. It Is weatherproof with an IP67 rating and has a fixed 4mm lens.
The 4MP Varifocal Bullet can zoom from a wider 3.2mm to a more narrow 9.8mm. (116 degrees to 34 degrees field of view). It also has an IP66 rating for outdoors and is weatherproof. In addition, it is compatible with perimeter guard and can make an audible noise. Though it can stream 1080P just like the 2MP Mini Bullet it can record 4MP on the SVR.
You can adjust the field of view from the web browser with the 4MP Varifocal Camera, but it just zooms in directly on the center of the view.
They both come with smart analytics and the ability to do onboard recording with a microSD Card. The 4MP is slightly large and does require a little more power than the 2MP Mini Bullet.
