The LEDs emit invisible light. But this is so weak in the highest level (for distant objects), that on 5 m optics delivers only more pixelated rushing pictures / video. I have also tried various resolution and still achieved no acceptable result. This can but much better red LED. That was the main reason to return them.
In addition, the connector is for the external current off the top (!) And inside out only with a simple rubber cap. The screams in bad weather (rain and ice can form) for problems.
The AA batteries can be loaded only with forced and one wonders when the plastic can no longer stand the pressure. Although the supplied tape for fixing is stable and good quality but fall a little short.
All in all a shame, because I otherwise the concept (menu navigation, display, remote control) and in particular the tone in the video really liked.
