I installed my G1 4g camera in our barn to monitor our horses. I used a 5v USB power supply as we have mains power in the barn, so I have not tested the solar panel. Installation was very easy using the QR code and the instructions. The camera connected instantly to 4g cellular with a very good signal. The quality of the image in HD is excellent, SD is acceptable. It is a very good idea to have the two day's trial of the sim card so you can make sure it all works. I then went on to subscribe to the sim deal at $9.99 per month, which I think is good value. All in all, a great buy - this is a quality product that works exactly as described, and I would happily purchase another one. Highly recommended.
