Common camera properties

This topic documents the camera properties that are common among video network drivers.

Figure 11. Example of Camera properties (naxisVideo driver, Workbench view)

To access these properties, right-click the camera component and click Views > AX Property Sheet.

In addition to the standard properties (Status, Enabled, Fault Cause, Health, and Alarm Source Info), these unique properties are common.

Property	Value	Description
Video Device Id	additional properties	Identifies the device. Refer to Video Device Id.
Ptz Support	check boxes, or `true` or `false`	Turns Pan Tilt, Zoom, Focus, Iris, Move To Preset, and Store Preset features on (`true` or enabled check box), and off (`false` or empty check box). Your camera may or may not support these features. NOTE: If these properties are not enabled, PTZ functions do not work. This means that any widgets that use PTZ controls do not work.
Control Timing	multiple properties	Represent Timeout and Interval settings for a set of the camera control properties. Refer to Control Timing properties.
Video Preferences	multiple properties	Configures how the video feed looks.
Credentials	Username and Password	Define the Username and Password required to access the device.
Preset Text	Opens the Enum Facets window.	Defines a set of pre-defined camera instructions each as a pair that consists of an integer (ordinal) and text command for controlling the camera. What to enter here depends on the camera. The options, once defined here, are available from the `Presets` option list on the camera Live Video view. Refer to “Enum facets window” in this guide.

Video Device Id

Three properties are available for identifying the camera.

Figure 12. Video Device Id properties

Property	Value	Description
Description	text	Adds information to more fully explain an object’s purpose, function or location.
URL Address	IP address in the format: ###.###.###.###	Defines the URL or IP address of the video device (camera or DVR).
Web Port	number (defaults to 443)	Defines the port, when using the web UI, over which to transmit the camera’s video signal. 443 supports only secure communication between the camera and the station. For a camera that does not support TLS secure communication, that is, if `Use Rtsp Stream` (Maxpro Camera property) is `true` or if you are using the HTTP protocol (`Use Tls` is `false` and `Use Rtsp Stream` is `false`), change this property to 80. CAUTION: Be aware that the framework cannot prevent a flooding attack or other malicious activity if you choose to configure your application without secure communication. If using fox streaming, which uses the station to render the video stream, this port should be different from the station’s fox port. If you are not using fox streaming, this port should be the same as the station’s fox port.

Control Timing properties

Figure 13. Control Timing properties

These settings affect how long a camera continues to respond to control communications after a control message is received. The reason for these limits is to prevent a camera from being left in a state of continual movement or adjustment (iris, focus, or zoom) in case communication with the device is lost.

Properties	Value	Description
Move, Zoom, Iris, and Focus Watchdog Timeouts	hours minutes seconds (defaults to five (5) seconds)	Defines the maximum amount of time that a camera control remains active after receiving the last control command. For example, if a move command directs a camera to pan right, and communication is immediately lost, the camera continues to pan right for five seconds and stops. You can adjust this time-out value for each of these controls: Move, Zoom, Iris, and Focus.
Move, Zoom, Iris, and Focus Intervals	hours minutes seconds (defaults to one (1) second)	Initiates a watchdog timer. When a camera does not receive a control communication after this interval elapses, the system assumes communication is lost and initiates this timer. You can adjust this interval for each of these controls: Move, Zoom, Iris, and Focus.

Description

Move, Zoom, Iris, and Focus Watchdog Timeouts

hours minutes seconds (defaults to five (5) seconds)

Defines the maximum amount of time that a camera control remains active after receiving the last control command.

For example, if a move command directs a camera to pan right, and communication is immediately lost, the camera continues to pan right for five seconds and stops.

You can adjust this time-out value for each of these controls: Move, Zoom, Iris, and Focus.

Move, Zoom, Iris, and Focus Intervals

hours minutes seconds (defaults to one (1) second)

Initiates a watchdog timer. When a camera does not receive a control communication after this interval elapses, the system assumes communication is lost and initiates this timer.

You can adjust this interval for each of these controls: Move, Zoom, Iris, and Focus.

Camera Device Extension shared property

Property	Value	Description
Do Not Ask Again	`true` (default) or `false`	Determines the type of connection to use between the station and the camera. `true` uses the fox connection to route video output from the camera to the station. `false` disables this feature.
