I just attached (and configured) a EX2Ulta to my network. Windows can see the device using file explorer /network/storage. Honeywell HRGX (in menu option add Network storage) has instruction to select the NAS device you want to add from list of network devices. My list of NAS devices does not include my new EX2Ultra.
Reboot should help. I have another question.
The new NAS (EX2 Ultra) tutuapp has the Milestone Arcus utility, which itself sees the cameras on the network and already records them on the NAS and can also be viewed online. So I want to do the same on EX2. It is necessary that my NAS act as a server. I do not want to buy an NVR separately. How to do it?
