- Instructions in English, but sufficient.
- Rechargeable batteries supplied (x3).. Average, I think we have to consider in place of other more successful thereafter.
- It must be loaded from the start thanks to the supplied USB cable, the solar panel is used only in addition to reloading. As soon as the indicator flashes red, recharge. For 10 days in gloomy weather, I did not yet charged. The unit does not fire unintentionally.
- Attention in 5 mode (+ high), ultrasound is audible even quite embarrassing for an adult. So it will choose its orientation to avoid the passing of adults in 15m front of the camera. In 4 here remains perceptible and children fit.
- The detection sensitivity is adjustable. I did not test for everything is at max.
Remains to be seen over time, including the sealing of the battery compartment and housing in general.
EDIT May 28: After 4 months of use, I have still not recharged and works perfectly.
