What are the best IR Security Cameras available from Uniview?

We tested three infrared cameras from Uniview to see which one had the best performance. We also explain in detail how infrared works, and what sort of image quality you can expect from your security cameras at night.
It's important to note that infrared has its limitations. For example, infrared can only produce black and white images. Also, you won't have as much detail from an IR camera as you would if there was supplementary light into the scene. One benefit of IR cameras is that they are covert - it's very difficult to see the light emitted from the camera with your naked eye.
