Unfortunately, the Spy Tank my expectations are not met:
1. the range is much too small to really benefit from Cam & Funk to draw.
2. The range is significantly lower than specified by the manufacturer. The connection already ripped between living room and hallway from (estimated 10m with a wall in between).
3. the quality of the camera is quite nice, but the fast driving image verschimmt so that driving is difficult and you have to watch really genuine, not somewhere to go against it.
4. the radio quality is moderate. Firstly, the transmission is greatly retarded and the other in the low range pointless because you can hear the person even without radio and understand even better directly. Feedback included.
5. Absolute downside and death criterion for the Spy Tank: According to the manual, the warranty is valid only in France, which could bring a claim a lot of postage expense and trouble with it.
I sent the Spy Tank back.
