The device seems not to use a residual light intensifier, but only works with IR illumination. The range is therefore very limited. Within the living room we got clear images, but if you turn the device to use the screen as a flashlight, you can see almost more. The picture is in fact quite small. As an application, I could imagine the observing nocturnal animals in a cage - because it comes close genung zoom. A terrarium disc one but again gets problems with the reflection of infrared light. For the wild, the range is not sufficient.
