What is the remote upgrade of the access control board? How to remotely?
Hello, the remote upgrade of our access control board is to replace the firmware program of the internal function part of the control, and rewrite the program. Restart after writing will automatically update the program. This function has strict requirements for refreshing, and no power failure or writing errors should occur in the middle, otherwise the access control board will be damaged. For non-professionals, we do not recommend remote upgrades by yourself.
