Introduction
AdvanceGuard® can control many individual Pan/Tilt/Zoom (PTZ) cameras. In order to manage potentially large numbers of devices, each individual camera is made to be a member of a camera group.
Camera Groups determine how cameras react to multiple tracked objects, according to how the group is globally configured:
Closest mode causes all cameras within the group to follow only the objects that are in their immediate vicinity.
Timeshare mode causes all cameras within the group to spread themselves between tracks, spending an adjustable amount of time on each, before moving to the next tracked object.
Static mode is designed for use only with Static Cameras. Although static cameras can never be moved, they can participate in automatic control groups to display targets in their field of view (FOV). However, once a camera is placed in a static group it will never be tasked for automatic tracking. This does not have any impact for any camera enabled for latching, they will still operate as expected. Like automatic control, a static camera can latch in order to display targets in their FOV.
Although cameras are usually controlled automatically, you can also take direct control.

Camera Control
In the example below, the camera is in the Timeshare Group, as displayed in the Configuration Tree. It is circled in pink on the PPI Map has been selected by left-clicking on it. This will open the Camera Mini Control on the right-hand side:
To focus a camera on a particular area, simply Ctrl+Right Click the area you wish to target and the camera will move to dwell there:
Camera Mini Control
The Camera Mini Control offers the following options to aid the operator:
Viewer: This opens the Viewer. Please see the section below on Using a Viewer.
Camera Home Position: This returns the camera to focus on its default home position.
Locate: This option locates the camera on the PPI Map.
Help: To open the Help Screen if enabled.
Automatic: This is a toggle between Automatic and Manual camera control. This is covered in the Camera Mode section below.
Height Map: These are very useful where a single camera needs to cover a region that has differing ground heights within it. Each Height Map is made up of grids, and each grid has a Height Offset option which allows you to inform the camera that when it is viewing that grid it should make tilt adjustments to account for the height difference. For further information please go to the Height Map page.
Using the Selection Menu
There is a quick way of accessing the Height Map for a camera:
The Selection Menu is accessed by a long left click on the PPI Map on the camera you wish to access.
The The Selection Menu will open. Using the curser, you can select the camera to open the Height Map:.
You can now view/hide the height map by toggling it on and off:
Camera Modes
Automatic: The camera will be controlled automatically by AdvanceGuard® based on the camera and camera group configuration. The automatic following of targets is controlled through the use of rules.
Mirror: This setting allows the camera to mirror a master camera in either automatic or manual mode.
Manual: The camera can only be controlled and moved by the operator.
Camera Mode Change
The camera mode change in the Camera Mini Control is an operators feature:
It allows you to switch between Automatic and Manual camera mode. This option means that an operator can quickly take manual control of a camera to follow a target and then, once they have finished their task, can return the camera to the Automatic setting.
Camera Latching
When a target has been selected for latching, a free camera capable of latching will follow the target.
The FOV outline (in pink) will appear when the camera is active and disappear when the camera is inactive.
In the example below, the selected track 2159 (in pink) had been latched to the camera, however, the operator latched a camera to track 2-1197 (in red), by right-clicking the track.
For further information about cameras, please navigate to the Cameras section.
Using a Viewer
Video viewers allow video inputs from cameras to be displayed for the operator when required. Most usually, video viewers are used in conjunction with optical or thermal imaging cameras that can be called upon when an incident occurs in the areas that they cover.
The Viewer has a Navigation Control very similar to that of the PPI Map.
Commands
Wiper: Select to enable camera lens wipers
White Lights: If this option is available, select to enable illuminating white light.
The direction keys are used to direct the view of the camera up-down and left-right, whilst the and are used to zoom in and out.
The ✖ is used to close the Viewer window.
The bar at the top labels the Viewer and the Camera the Viewer is streaming from.
The window controls are to maximise/minimise the Viewer window, or to exit.
In the example below, the camera has been automatically tasked by the system to follow the Track. The operator has selected the Viewer (circled in orange) from the Camera Mini Control which has opened the Viewer on the top left of the PPI Map, and also the Viewer Mini Control, highlighted on the top right. The track and camera have been highlighted in the middle of the PPI Map:
