Communication error due to digital certificate change - April 2021
Last update: March, 2021
Please be informed that the digital certificate installed in our network cameras and network disk recorders is changed from Digicert certificate to GlobalSign certificate, from April 2021.
A network disk recorder may fail to connect to a network camera with GlobalSign certificate installed, in SSL encrypted communication, when the firmware version of the recorder is 4.20 or older. This can result in a communication error on the recorder.
When you see the error, upgrade the firmware of the recorder to version 4.30 or later.
The firmware version 4.30 or later supports both Digicert certificate and GlobalSign certificate.
As digital certificate is used only in SSL encrypted communication (HTTPS communication), firmware upgrade is not required when you do not use HTTPS.
