The view starts at this unit's own magnification. The further away the animal, and the wider the field of view, the less detail the sensor picks up, until you can tell something warm is there but not what it is. Zooming in makes it bigger, not sharper.

Example image only. Not filmed through this product. Pig and deer stills supplied by HIKMICRO and Nocpix; fox and rabbit are thermal-style images we made from photos by A. Omer Karamollaoglu (CC BY 2.0) and Alexis Lours (CC BY 4.0). Field of view and zoom are simulated from this unit's 640×512 sensor and 25 mm lens, 1.4× base magnification and 1024×768 screen. Real results change with weather, display and settings.
