Answer: although the unit charged correctly when setting up, I installed the Solar panel at its place (18ft high in a tree) and found it wouldn't charge the camera. I immediately, and I think sensibly, thought the problem lay in the Micro USB attached to the Solar panel. After contacting the Manufacturer in China, they were about to depart on their Mammoth Chinese New Year - so the help and warranty goes on hold. I contacted Amazon and they suggested I buy another SP, which I did and plugging it into the camera found, to my surprise (as the camera had charged okay at time of set-up) the issue was not with the Micro USB on the SP but the USB on the camera. I can only assume that whatever the means of securing the USB connector in the camera (adhesive, crimp whatever) it was not sufficiently robust to withstand the withdrawal of the USB 5V power cable after charging. I wasted about a week and Such a pity as the camera works fine. Read the comments below. I hope K&F Concept interrogates the unit returned to Amazon to avoid future issues, such an incopetence to bruise a reputation for something so avoidable:Setting up the camera:I bought this camera from a review that confirmed it worked from a distance of 340 ft. My gateway being installed is around 310 ft. When going through the setup using the app CloudEdge downloaded from Apple, I found in the Settings an Installation Guide. I use an ORBI Netgear Mesh WiFi with only one Booster in my house - I plugged the Booster in the garage as I had found before that a garage-door has less signal attenuation than a brick wall. At 320 ft from the Booster with the garage door shut, I can a receive a signal using a WiFi SpeedCheck of 10-16Mbps download and 6Mbps upload. The Installation Guide will only announce perfect Wifi of 4 bar strength to select an installation location - Don't worry - If your camera at its location is only two Bars with a 'Not fit for camera installation' the signal is adequate. A camera only requires say 4Mbps. (The Photos show the 18ft high tree -nstallation and the 310ft distance from the house plus the current shot from the camera of the gate install). The Infra Red imaging is brilliant.Caution - I think there is an error in the instructions of the camera that states a 15 minute initial charge but later states the charge time as 15 hours. I charged for about 20 minutes and it read 'fully charged.'I installed a (recommended max) 128mb Micro SC (not included) and so far taking images and movies with the shot time 'off 'I'm always charged (but I do live in Florida).Conclusion: But for Chinese New Year and the unforgivable fault in the mounting of the only part of the camera that needs interaction with the customer, i.e. the Micro USB, I highly recommend this camera - its performance is extraordinary at the range possible. I also commend Amazon - for exemplary service. So if you purchase you now know what to look out for. Enjoy....
