Good day Is it possible to leave these cams connected to the mains? I would like to keep the cam plugged in so that I don't have to disconnect it to charge the battery. Is this possible or not possible? If not, is there an outdoor cam from Xiaomi where this would be possible? Otherwise, this cam would be built exactly the way I want it. Xiaomi - Mi Wireless Outdoor WiFi Internet IP Camera FullHD 1080p 130° Viewing Angle Night Vision / Audio / Micro SD / iOS/Android (IP65) Kind regards Carlo Brunner
