I wanted to upgrade and access the images on my iPhone from a POE security system installed in 2012 with Acegear cameras and a Samsung DVR. I contacted Annkee support and asked what was possible. I received excellent service and a very practical solution: simply replacing the Samsung DVR with an Ankee DVR and using the Ankee Vision imaging app. I purchased the Ankee 4K DVR, replaced the DVRs, and configured the new one. It was very simple. I turned it on, and all the cameras were on my monitor.
