While supported ONVIF cameras with motorized varifocal lenses can only zoom in and out (Simple PTZ), DW Spectrum also allows users to easily point PTZ cameras through the DW Spectrum Client, rather than having to connect an external joystick.
This article will outline the available PTZ controls of DW Spectrum.
Note: Auto-focus and zoom are enabled for supported non-PTZ cameras by default.
When PTZ requirements are met for a compatible PTZ camera, the PTZ icon will display in the camera’s viewing window.
Standard PTZ is an included function of DW Spectrum. By default, PTZ control will automatically be enabled for supported cameras by the camera’s native presets (manufacturer configured) and how DW Spectrum determines if it will use the camera’s presets or use its preferred presets instead.
You can find this setting under the PTZ section by right-clicking on the camera, opening Camera Settings, then selecting the Expert tab.
By default, the Preferred PTZ preset type will be set to Auto, allowing users to simply add the camera and begin using the PTZ function. If needed, you can change the setting to Native to only use the camera’s PTZ setting presets or change the setting to System to ignore the camera manufacturer settings in favor of using DW Spectrum settings only. Otherwise, it is recommended to leave the setting as Auto.
By clicking the PTZ icon in the camera’s viewing window, users can activate DW Spectrum’s PTZ controls. Click the PTZ icon again to hide the PTZ controls.
Depending on the camera model, one of the following modes will be made available.
Simple (Zoom only) – this feature is represented by a set of plus (+) and minus (-) buttons that allow users to zoom the camera lens in or out through the DW Spectrum interface. This option does not allow users to pan or tilt the camera as it is typically associated with cameras with zoom functionality only.
Regular PTZ (zoom and point) – this feature is represented with the same zoom controls as the Simple (Zoom only) PTZ feature, but it is also accompanied by a “center circle” that can be used to click-and-drag to point the PTZ camera to a desired position.
Extended (zoom, point, and additional features) – this feature requires ONVIF Absolute Move support by the camera and custom product integration with DW Spectrum. It includes the same features as the Regular PTZ (zoom and point) feature as well as:
Camera models that support the advanced PTZ features (Regular PTZ and Extended PTZ) can be found using the DW Spectrum Supported Device List.
When troubleshooting ONVIF camera issues, such as PTZ control problems, it is recommended to download and install ONVIF Device Manager on the same computer as your DW Spectrum Server. If you cannot install the ONVIF Device Manager (ODM), because you are using an Ubuntu/Linux or Macintosh operating system, install ODM on a Windows PC that shares the same LAN as your troubled camera.
