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.
Out of the box I had an issue with camera 2 cutting out. I went to the website and got the latest driver and updated all 4. The I noticed the night vision was degraded. Tech Support helped me to adjust that aspect of the performance. Great support and a really professional system. I went 4K and it was the right call. So was going with Swann.
