2022 Essen Security exhibition ends successfully
2022 Essen Security exhibition ends successfully The German exhibition is really good. The exhibitors are all international manufacturers, such as OPTEX, Takex, Dahua, Hikvision, Solhea, Genetic, and of course, Taiwanese manufacturers Vivoteck, Sengate, Eten.    In the past two days, we have encountered many small European countries, such as Slovenia, Latvia, North Macedonia, Lithuania, Croatia, etc. Only then did we realize that we don’t even know their English country names, we only know them Chinese translation is really embarrassing, but these small European countries all have security equipment needs and hope that they can support and trust Taiwan's products.        It was my first time to go abroad for an exhibition, and it was only when I arrived at the scene that I found a lot of situations, which really tested our crisis handling ability. The booth was transferred to the border by a German curator The electronic system of our exhibit is not acclimatized Poster gets damp during shipping    The plan is always unable to keep up with the changes. No matter how detailed the plan is, there will still be omissions or unexpected problems. Especially when encountering situations abroad, if you are not familiar with your life, you should find a hardware store such as Xiaobei Department Store. Don't know where? Fortunately, most of the problems have been resolved, allowing us to open and exhibit smoothly. #SENGATE #ESSENSECURITY2022 #MESSEESSEN
