Voice Encryption
Secure Real-time Transport Protocol (SRTP) is a protocol derived from the Real-time Transport Protocol (RTP). It enhances the security of data transmission by providing encryption, message authentication, integrity assurance, and replay protection.
Set it up on the Account > Advanced interface.

Voice Encryption:
Disabled: The call will not be encrypted.
SRTP(Compulsory): All audio signals(technically speaking it is RTP streams) will be encrypted to improve security.
SRTP(Optional): Encrypt the voice from the caller. If the caller also enables SRTP, the voice signals will also be encrypted.
ZRTP(Optional): The protocol that the two parties use to negotiate the SRTP session key.
Web Interface Automatic Log-out
You can set up the web interface's automatic log-out timing, requiring re-login by entering the user name and the passwords for security purposes or for the convenience of operation.
Set it up on the web Security > Basic interface.

High Security Mode
High security mode is designed to enhance the security. It employs encryption across various facets, including the communication process, door opening commands, password storage methods, and more.
Enable/disable the mode on the Security > Basic interface.

Important Notes
1. The High Security mode is off by default when you upgrade the device from a version without the mode to one with it. But if you reset the device to its factory settings, the mode is on by default.
2. This mode makes the old version tools incompatible. You need to upgrade them to the following versions or higher to use them.
PC Manager: 1.2.0.0
IP Scanner: 2.2.0.0
Upgrade Tool: 4.1.0.0
SDMC: 6.0.0.34
3. The supported HTTP format for relay triggering varies depending on whether high secure mode is enabled or disabled.
If the mode is on, the device only accepts the new HTTP formats below for door opening.
http://username:password@deviceIP/fcgi/OpenDoor?action=OpenDoor&DoorNum=1
http://deviceIP/fcgi/OpenDoor?action=OpenDoor&DoorNum=1
If the mode is off, the device can use both the new formats above and the old format below:
http://deviceIP/fcgi/do?action=OpenDoor&UserName=username&Password=password&DoorNum=1
4. It is not allowed to import/export configuration files in tgz. format between a device with the high security mode and another one without it. For assistance with file transfer, please contact Akuvox technical support.
