Axxon PSIM allows you to connect devices via the ONVIF protocol and fully supports S, G, T profiles. An ONVIF profile is a certified set of device functions.

There are two drivers available in the product:

• ONVIF (single-stream) that works with the axxon0 profile,
• ONVIF 2.X (double-stream) with models according to the number of device channels that works with axxon0F (first stream) and axxon0S (second stream) profiles. 

Creating devices using the ONVIF protocol

To add an ONVIF device to Axxon PSIM, do the following:

1. Start Camera discovery tool.
   
2. In the Brand list (2), select ONVIF or ONVIF 2.X.
3. In the Model list (3), select the number of device channels.
4. In the Firmware list (4), select auto.
   As a result, the discovered devices are displayed in the Brand list (2). If the required device isn't displayed, proceed to the next step. If the device is displayed, proceed to step 6.
5. Add the device manually:
   1. In the IP address field (12), enter the IP address of the device.
   2. In the Port field (13), enter the TCP/IP port number.
   3. In the Brand list (14), select ONVIF or ONVIF 2.X.
      

      To use multistreaming via the ONVIF protocol, select the ONVIF 2.Х brand and the 1-channel-multistream model. You can configure the streams of the connected ONVIF device in the standard way (see Configuring the multistream video).

   4. In the Model list (15), select the number of device channels.
   5. In the Firmware list (16), select auto.
   6. Click the Add button (17).
      As a result, the ONVIF device with the specified parameters is displayed at the top of the Camera discovery tool window.
6. In the Settings list (5), select: 
   1. Video server settings, if you want to send the settings specified in Axxon PSIM to the device when you add it.
   2. Device settings, if you want to use the device settings.
7. Enter login (6) and password (7) to connect the ONVIF device. The login and password are specified in the documentation for the network device that you connect.
8. Check if the TCP/IP port (8) is correct. If necessary, enter the required value in the field.
9. Select the objects that you want to create on the basis of the ONVIF device by setting the corresponding checkboxes (9).
   

   For more information, see Camera discovery tool.

10. Click the Apply button (10) for one device or the Apply button (11) if several devices are selected.
    The selected objects are automatically created in the object tree on the Hardware tab.
    
11. Click the Exit button (18) to close the Camera discovery tool window.

Creation of the ONVIF device is complete.

Advanced settings for ONVIF device

• The IP address rewriting and RTSP port rewriting parameters enable/disable the ability to connect to cameras behind NAT (Network Address Translation) via ONVIF.
• To configure the RTSP port, the 0 value is set by default. In this case, the RTSP port number is read in the request from the camera that is sent during device initialization via the HTTP port that is specified in the Port field.

Working with ONVIF devices 

• When you work with the archive on multi-channel devices, you can work with only one channel in the archive mode at a time.
• The signal loss timeout allows you to set the time interval after which the software displays the signal loss notification.
• In some cases (for example, if there is no video from the device), when you connect cameras via the ONVIF protocol, it is necessary to synchronize the time and time zone between the server and the device in the web interface of the latter.
• ONVIF devices operate:
  • with preset camera profiles, if you enable the compatibility mode (in Axxon PSIM, you can set it using the registry key; see below),
  • with profiles that are created when you connect to the camera and used when you work in the software.
