We bought the original system with 4 cameras in March of 2022. We decided to add more cameras and this summer July 2024 we bought additional cameras and the solar panels, etc. We are really pleased with how these work. We don't get a ton of winter sun, so we didn't expect the solar-powered ones to last all day, but we are pleased with how long they are lasting.Unfortunately, the original monitor from 2022 suddenly died today. We tried to go back and leave a review or update our existing review and we're blocked from reviewing that product. We've never been blocked from reviewing anything before, so we're reaching out to Amazon to see why that is. Overall, happy with the system, except the monitor only lasting 2.5 years isn't great. Also it doesn't look like you can buy the monitor by itself. Worried that there will be a compatibility issue if we buy a new system, with these cameras we bought in 2024.
