New to the grandstream stuff, recently installed a GDS3710 in a small daycare. Parents have a PIN number they all share to get in front door to pick up their children. Teachers have rfid cards.
Complaint: randomly the intercom will not accept valid PIN number. Will not open the door. When this is happening, the rfid cards will still work. I arrived to look at this one time just after it had happened, so I looked at the event log and it shows no log of the PIN entry attempts. It does show the card swipe and entry in between the PIN attempts.
Question: does this GDS3710 have an incorrect PIN number lockout after a number of incorrect attempts? I can’t find a mention of this anywhere, but my thought was that a parent had put in the wrong code too many times and it locks out the pin entry for x minutes or something?
