I was skeptical when purchasing this solar panel for my daisy chain Cuddeback J series camera system. I currently have seven cameras out in the field on about 100 acres of River-birch and cottonwoods mostly along the creek bed. I put one of these at the base of a bluff on my property a year ago. Since then I have had no problems with the camera and have not changed any batteries because the solar panels been working great. I am so impressed with these that I have purchased more of them. They will pay for themselves in a years time so I figure I’ve got my moneys worth. Keep in mind the camera I have it on is in the direct sunlight most of the day. (Update on October 15, 2023) Currently the camera at the bluff has been working for over 1100 days straight with no issues. All I’ve done is clean the camera and the solar panel, best camera product I’ve ever owned. I just ordered the LTE home base camera and now I am getting an LTE signal and using these older J series cameras, and they work great with it. Now I can have the pictures sent to my phone and my email and 10 other people all I did was invest $130 for the home LTE receiver. I then swapped out the old home camera with the new home LTE receiver. Purchased the plan($15 a month version) and make sure I have a good signal on my property. Also I update all the firmware in all 7 of my J series cameras, which is very easy. I just got the SD card from Cuddeback with firmware already installed for $15 and put it in all cameras and updated them with most current firmware. I was very surprised how easy it was. I will update this in about a year and see how good this system is working. Keep in mind I put most of my cameras in a homemade wooden camera box to keep most of the weather off of them, then I mount the solar panel on top of it. Anyway, I hope this helps anyone who is interested in purchasing these cameras (Any Cuddeback series)They are worth it especially the solar panels. We have a coougar problem in this state because they don’t allow you to run dogs. Furthermore, we are finding more and more cougars right next to our house and with three children there’s no way we’re gonna allow them to thrive. We’ve got the end them out. You can monitor the pictures on the Cuddeback website and they also have a app for your smart phone. I use both of them and they’re really easy to use. Furthermore,Cuddeback has very good customer service and I’ve always had someone on the phone with in a few minutes. Good luck!
