aosu Security Cameras Outdoor Wireless, 4 Cam-Kit, No Subscription Required, Solar-Powered, Home Security Cameras System with 360° Pan & Tilt, Auto Tracking, 2K Color Night Vision, Easy Setup

I got a four pack system from AOSU on Amazon. Had them about a month now and I've been happy with them so far. I live in Wisconsin so they haven't been thru a winter yet. That could change my mind. They only downside is the 32GB of storage. I'd like to have more so clips don't get overwritten if we can save them off in time. Not sure if this is upgrade able but I haven't checked yet either.
