Randy747 Were you shooting during the daytime? Did you aim at a distant location (unobstructed and over 1 kilometer away) for shooting? It’s best to shooting towards a house or a tree. You can also adjust the brightness for testing.First, aim at the approximate position, then focus manually or use auto-focus. Additionally, when and where did you purchase your device? If it is broken, you may need to contact the dealer you bought it from for repairs.
