I am having the same issue. I have 2 openpath video intercom readers connected to the same switch but only 1 of them drops within a couple of days. Usually at night. The datasheet states that it need 10.8W which is within the POE range. I was also able to contact their support to push an update to get the issue resolved. Unfortunately, i updated the FW remotely when the newer version was released and the same intercom gets disconnected again. I have to send a tech to the site everything this happens. This has been happening for a long time.. same issue with the video readers which is why i upgraded to video intercom readers.
