By default, all ONVIF devices in the system are added as multistreaming (the ONVIF 2.0 driver, see Adding and removing IP devices).

If the camera does not support multistreaming, then the video stream of lower quality will be disabled.

Info
titleNote

In some cases (for example, if you do not have video from a camera), you may need to synchronize the time between the server and the camera when you connect them via ONVIF.


Note
titleAttention!

If you connect cameras via ONVIF, auto focus (AF) and auto aperture are not available.

Connection through ONVIF Generic driver

With the ONVIF Generic driver, you have the following options:

  1. Currently offline cameras can transfer their settings when they get back online.
    To make it happen, follow the steps below:
    1. Add a camera via the ONVIF Generic driver (see Generic Drivers (General device, generic)).
    2. When the device comes online, reset its parameters (see Applying and resetting settings).
    3. Load the configuration from the device (see Applying and resetting settings).
  2. You can select another camera in object settings while keeping all layouts, macros and archive storage parameters.
    To make it happen, follow the steps below:
    1. Add a camera via the ONVIF Generic driver (see Generic Drivers (General device, generic)).
    2. Set archive storage parameters and create macros.
    3. In Camera object settings, specify a new IP address and user credentials (see The Camera object). 
    4. Reset device settings (see Applying and resetting settings).
    5. Load the configuration from the device (see Applying and resetting settings).

This operation will result in swapping cameras without the need to create a new object and remove the old one. 

Resolution

C-Werk offers three resolutions for video from cameras connected via ONVIF: maximum, medium, and minimum.

A description of the resolution levels is given in the table.

IP devices on other subnets (behind a NAT)

By default, NAT-friendly mode is enabled for cameras connected via the ONVIF driver.

To disable NAT-friendly mode, in the settings of a camera, select the No value for Remapping IP-address.

IP devices which partially support the ONVIF protocol

To connect IP devices which only partially support ONVIF functions to the C-Werk software package, you must use an ONVIF driver with compatibility mode enabled.

Info
titleNote

Such video cameras include Hikvision models and early versions of firmware from Sony, Samsung, and others.

Compatibility mode makes it possible to receive a video image from video cameras; however, some capabilities of the C-Werk software package will be unavailable. Enabling compatibility mode is recommended if the connection settings are correct, but there is no video image.

To enable it you need:

  1. Select the Send settings to device checkbox (1).

  2. Select Yes for Compatibility mode (2).
