400 resolution, 10mm, 2 LUX
500 resolution, 50mm, 2 LUX
500 resolution, 50mm, .05 LUX

When you select cameras, be aware of the following characteristics:
• The resolution is rated in the number of lines included in the image. In general, the higher the resolution, the sharper the image.
• The focal length measures the magnification power of a lens. The focal length controls the distance that the camera can see, as well as how much detail can be seen at a specific range. A higher focal length lets you see more detail at a greater distance.
• LUX is a measure of the sensitivity to light. The lower the number, the less light is necessary for a clear
Image.
