To use for the price well. Previously you should worry whether it is sufficient for the required purpose. The increase is clearly visible. The image will be S / W reproduced. Due to the light output, the field of view is quite narrow (very focused) and more designed to observe certain points. Who wants to watch a larger area is rather poorly served by the narrow field of view. I tested in total darkness with the built-in IR light up to 30m, there everything is well illuminated. The light, however, the device visible. Through the narrow field of view, within 100m approximately 6,6m field of view, you have to readjust often at different distances, even at a short distance change. Resolution of 580 x Kammera 500th
The built-in video port is useful when you want to take pictures of what you see. In daylight (cloudy) / twilight, the device is also available. Only to bright light hurts him. Crescent Moon in an open area, it brightens enough on without the extra light.
For the price not expect miracles. Generally, however, easy to use.
