Advanced PTZ Options Overview

To provide an advanced explanation of the different Pan/Tilt/Zoom (PTZ) options available in the camera's Web GUI under the SYSTEM tab, refer to the following sections.

PTZ Settings

PTZ Speed

You can increase the maximum pan and tilt speed, which is useful in scenarios like conference systems where quick movement is necessary. However, setting the PTZ speed to 'high' may cause the camera to produce slightly more noise. For example, using the IR remote control, the camera will complete a full pan in approximately 3 seconds when the PTZ speed is set to HIGH, compared to around 5 seconds when set to LOW. The same concept applies to tilt movements.

  • Note: If your camera pans or tilts very slowly despite the PTZ Speed being set to HIGH, the 'Speed by zoom' option described below might be enabled, and the camera could be zoomed in to its maximum.

Speed by Zoom

This mode affects PTZ speed when the camera is zoomed in to its maximum. If you move the controller stick when this mode is disabled, the camera will move too fast to control effectively. Enabling this mode reduces the PTZ speed in relation to the current zoom factor.

Image Freezing

  • You can freeze the image when the camera moves from one preset to another preset by selecting them using your IR remote controller or hardware controller. This is particularly useful in applications where you do not want to see the camera pan between two presets.
  • Note: If you are using audio during streaming, ensure that you turn it OFF before freezing the image. Freezing the image could result in a paused audio output on the IP Stream, leading to audio stuttering. While the video might stutter when re-engaged, this can be mitigated by setting the iFrame value to 4 or 5 times per second, which helps counteract video stutter.

Low Power Mode

The Avonic CM70 series cameras are designed to consume very little power in stand-by mode. To achieve this, some features within the camera are completely shut down by default, including the LAN port. We have introduced the "Low Power Mode" feature for those who require the camera to be powered on over IP. Previously, Low Power Mode had to be disabled first, but it can now also be disabled via HTTP API commands or VISCA serial/IP commands (refer to the camera user manual for commands).

  • Note: If the camera cannot be booted up through Visca over IP because Low Power Mode is active, the camera can only be turned back on using the physical switch on the back, the remote control, or by sending a command via a serial connection.

Enable/Disable Infrared Receiver

It is possible to enable or disable the Infrared Receiver. Note that when the Infrared Receiver is disabled and Low Power Mode is enabled, you will not be able to activate the camera again using the IR Remote Control. In such cases, you will need to power the camera via a serial connection or re-enable the Infrared Receiver before activating the camera with the remote control.

Zoom Speed

You can set the speed at which the camera will zoom into the image. A higher number indicates a faster zoom speed. This setting is effective only when the remote controller is used to control the camera.

  • Note: This feature does not affect cameras controlled using our hardware controller CON300-IP. The CON300-IP has its own "PTZ Speed" settings to control PTZ speed, which takes precedence over the settings in the camera Web GUI.

Preset Pan, Tilt, and Zoom Speed

This setting affects the speed at which the camera switches from one preset to another when using your (remote) controller. A higher number means faster switching. By default, all preset PTZ speeds are set to their maximum levels.

OSD Menu Options

Some of the above PTZ options are also available in the camera's On-Screen Display (OSD) menu:

  • Note: The OSD Menu is visible only on the CM40 and CM7x HDMI and SDI outputs (not on USB or IP outputs).
