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 cameras doesn't support multistreaming, then it will the low quality video stream disabled.
Note
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.
Attention!
If you connect cameras via ONVIF, auto focus (AF) and auto aperture are not available
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.
| Camera type / Resolution | Maximum | Medium | Minimum |
|---|---|---|---|
| Non-megapixel | Maximum camera resolution | Average camera resolution | Minimum camera resolution |
| Megapixel | Maximum camera resolution | Camera resolution closest to 1024x768 | Camera resolution closest to 640x480 |
Using standard presets
To use standard presets of your IP device for ONVIF connections, do as follows:
- Go to the Telemetry object (see The PTZ Object).
- Select Yes in the Use device presets option (2).
- For Standard presets (3), select one of two values:
- Use in device presets order - C-Werk uses the direct order of presets on your device.
- Use in reversed device presets order - C-Werk uses the reversed order of presets on your device.
- Save changes.
- Create the required number of presets (see The Presets List)
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 Overriding 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 (1) with compatibility mode enabled.
Note
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 for a video camera (2) connected using the ONVIF protocol (1) is recommended if the connection settings are correct, but there is no video image.
