To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I got this product and installed it on my front door. It was working fine, but after a few weeks a static noise appeared when someone rang the doorbell or selected the talk button. I contacted the manufacturer and they have kept me busy for months now making troubleshooting videos of the problem, but they haven't been able to fix it. They asked me to try different cables short, long, relocate the monitor away from the door bell, etc, and every time I send them a video they ask for another test. Maybe I got bad luck with this one but it is useless. Also, there was another problem with the pictures, I get some kind of corrupted pictures now and then, so I tried to erase all the pictures, but all 100 pictures reappear every time I delete them. Not happy with the purchase.
