Client Certificate Setting
Certificates ensure communication integrity and privacy. To use the SSL protocol, you need to upload the right certificates for verification.
Web Server Certificate
It is a certificate sent to the client for authentication when the client requests an SSL connection with the Akuvox door phone. Please upload the certificates in accepted formats.
Upload the web server certificate on the Security > Advanced > Web Server Certificate interface.
Motion Detection
Motion Detection is a feature that allows unattended video surveillance and automatic alarms. It detects any changes in the image captured by the camera, such as someone walking by or the lens being moved, and activates the system to perform the appropriate action.
Set up motion detection on the Intercom > Motion interface.
Motion Detection: Enable or disable the IR sensor-based motion detection for suspicious moving objects.
Time: The absolute triggering interval is 3 seconds. If you select a number greater than 3 seconds, then it requires a second triggering interval to trigger the alarm. For example, if you select 3 seconds, then the alarm will be triggered when a moving object is detected one time from 0 to 3 seconds (triggered any time from 0 to 3 seconds). However, for example, if you select 5 seconds (greater than 3), then the alarm will not be triggered until a moving object is detected for the second time from 3 to 5 seconds (triggered any time from 3 to 5 seconds). The default interval is 10 seconds.
Action to Execute: The notification type includes FTP, Email, SIP Call, and HTTP.
FTP: The notification will be sent to the designated FTP server.
Email: The email will be sent to the pre-configured email address.
SIP Call: A call will be made to the pre-configured number.
HTTP: The notification will be sent to the designated server.
HTTP URL: Enter the HTTP message if selecting HTTP as the action to execute. The format is http://HTTP server’s IP/Message content.
Motion Detect Time Setting: When motion detection is enabled, you can set a specific time for the feature to be effective.

4 | Relay Closed | $relay1status | Http://server ip/relayclose=$relay1status |
5 | Input Triggered | $input1status | Http://server ip/inputtrigger=$input1status |
6 | Input Closed | $input1status | Http://server ip/inputclose=$input1status |
7 | Motion Detection | $active_user | Http://server ip/active_user=$active_user |
For example: http://192.168.16.118/help.xml? mac=$mac:ip=$ip:model=$model:firmware=$firmware:card_sn=$card_sn
To set it up, go to the Device > Action URL interface.
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 web Account > Advanced > Encryption interface.
Voice Encryption(SRTP): Choose Disabled, Optional, or Compulsory for SRTP. If Optional or Compulsory is selected, the voice during the call is encrypted, and you can grab the RTP packet to view it.
User Agent
User agent is used for identification purpose when you are analyzing the SIP data packet.
To set it up, navigate to the Account > Advanced > User Agent interface.
User Agent: Akuvox is by default.
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 it on the Security > Basic > High Security Mode 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.

Emergency Audio-Visual Alert Setup
This feature allows E21 to manage and broadcast customized alarm audio files based on predefined alarm IDs.
When an alarm is triggered by the R49 broadcast, E21 can:
Play a predefined audio file.
Activate relay outputs for external alarm devices (such as LED indicators or speakers).
Identify devices by area and location for zone-based alarm management.
This feature supports zone-oriented emergency notification and coordinated alarm control.
Set it up on the Security > Basic interface.
Device Area ID: The range is 1–254 (optional).
Defines the area number to which the E21 device belongs.
This parameter is used for zone-based alarm control and broadcast management.
If configured, the device responds to alarm broadcasts targeting the same Area ID.
If left empty, the device is not restricted by area-based filtering.
Device Location ID: The range is 1–254 (optional).
Defines the specific location number of the device within an area.
It is also used to determine how the E21 activates its relay outputs when receiving an alarm broadcast containing a location ID.
If the received Location ID is less than the device’s Location ID:
→ Relay 1 is activated.
If the received Location ID is greater than the device’s Location ID:
→ Relay 2 is activated.
If the received Location ID is equal to the device’s Location ID:
→ Both Relay 1 and Relay 2 are activated.
Alarm Name: A user-defined label for each alarm ID. Used for identification in the configuration interface. Does not affect triggering logic.
