I have the predecessor model TSE acquired 5002 2010. I regret to say that the finger scanner is apparently not suitable for the normal weather-protected outdoor installation on time. After almost 12 months of the first scanner gave up his ministry and after a further 14 months the second. The First there was hesitation on warranty. Unfortunately the second scanners. After demand for Burgwächter why that is, I was told that this device should only be used in absolutely dry areas such as closed porch or indoors, this also applies to the successor business TSE Set 5012 fingerscan. A new scan engine or a new device, I'm going to no longer set by the company Burg Wächter.
