Connection through ONVIF Generic driver
With the ONVIF Generic driver, you have the following options:
- Currently offline cameras can transfer their settings when they get back online.
To make it happen, follow the steps below:- Add a camera via the ONVIF Generic driver (see Generic Drivers (General device, genericGeneric)).
- When the device comes online, reset its parameters (see Applying and resetting settings).
- Load the configuration from the device (see Applying and resetting settings).
- 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:- Add a camera via the ONVIF Generic driver (see Generic Drivers (General device, genericGeneric)).
- Set archive storage parameters and create macros.
- In Camera object settings, specify a new IP address and user credentials (see The Video Camera Object).
- Reset device settings (see Applying and resetting settings).
- 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.
