This effort was too high for me. Therefore, the test me this dummy camera.
She looks around from quite real, the difference to a real 3 meters can not be determined. The LED will blink and blink and blink - I have the Eneloop batteries (not migeliefert) over 6 weeks before reingetan and not previously have to change.
The design is ok, they must withstand not much indeed. There are small screws and Dübelchen it.
Additionally, I have found me "real" sticker with a warning sign on the video surveillance, which are also attached to monitoring systems of the brand manufacturer. This means that potential burglar has a pretty brainteaser with risk assessment in front of him.
Conclusion: One can definitely confuse potential burglars at least greatly, because if the camera is mounted high enough out of his reach, can the "candidate" definitely not tell if he looks in the optics of a dummy or is already filmed ...
