I have 3 dcs 2120 to cover different areas of the house and 1 dcs 5220.
All are setup correctly and able to send emails on motion. The issue is they all can't be on to send emails. I done extensive tests where if all units are on, the first unit that powers on can send motion detection emails and logs If I turn the first unit off, the one of the remaining three are able to send motion detection emails and logs.
So basically as I turn units off, email will start to work. Does these unit lock on to a certain port and not let go ? Or is this design to work like that ? These units are behind a FIOS router.. did not work when I was on cable modem either.
I do have different IPS for them, tried different dns, tried different smtp mail servers, none of it have effect on getting at least 2 units to send emails out at once.
Recording with the dlink software works but I really want motion detection emails.
