Best Monoculars For Surveillance - With Infrared

The main consideration when selecting a monocular are the magnification level and objective lens diameter, which determine the optical capabilities of the monocular. The bigger the objective lens diameters, the better the image quality and the heavier the monocular may get. Waterproofing and night vision (thermal or infrared) are also important factors to consider when selecting a monocular.

Monoculars for surveillance should be small but still offer good performance. Consider choosing a maximum magnification of 10x and an objective lens diameter of not more than 42mm. An 8x42 monocular weighs about 1.5 lbs. (0.7 kg) and a 10x25 one weighs about 0.75 lbs. (350 grams).

Infrared monoculars enable the detection of a target in the dark using an infrared illuminator that is invisible to the human eye. Infrared monoculars are normally not as good at detecting targets as thermal ones; however, they are normally less expensive.
