DESCRIPTION¶

Uses Milestone's Configuration API to modify properties of cameras and saves the changes to the Management Server. Most parameters represent the Milestone MIP SDK property names of the underlying camera object. However, there are a few custom parameter names including "Coordinates", "Direction", "FieldOfView" and "Depth" which accept values that are easier to understand than the values expected by the MIP SDK.

This cmdlet supports the "-WhatIf" parameter switch. Use this to test to see what would happen and if the changes made are what you would expect to see. You may also use the "-Verbose" switch without the "-WhatIf" switch, and you will see all the changes applied to the camera(s).

You do not need to use this cmdlet to make configuration changes to cameras. You could choose to modify the properties directly on the camera objects, and then call the ".Save()" method on the object(s) when you're ready to push those changes to the Management Server. However, this cmdlet provides an idiomatic PowerShell option to accomplish the same task with less effort.

REQUIREMENTS

Requires VMS connection and will attempt to connect automatically

EXAMPLES¶

Example 1¶

Connect-ManagementServer -ShowDialog -AcceptEula
Get-VmsHardware | Get-VmsCamera -Channel (1..63) -Verbose | Set-VmsCamera -Enabled $false

<# OUTPUT
VERBOSE: Performing the operation "Changing Enabled from True to False" on target "Cash Register".
VERBOSE: Performing the operation "Saving changes" on target "Cash Register".
VERBOSE: Performing the operation "Changing Enabled from True to False" on target "Entrance".
VERBOSE: Performing the operation "Saving changes" on target "Entrance".
VERBOSE: Performing the operation "Changing Enabled from True to False" on target "LPR".
#>

In this example, we first ensure we are logged in to the Management Server. Then we gets all enabled cameras with a channel number between 1 and 63 (camera 2 to camera 64), and disable them. You might do this if you only use the first channel on every camera, and all other channels should be disabled. In this case, channels higher than 63 would be unchanged. If you had devices with more unused channels than this, you could use "(1..511)" to select all cameras from the 2nd to the 512th channel.

Example 2¶

$selectedCameras = Select-Camera -AllowFolders -AllowServers -RemoveDuplicates
$props = @{
    PrebufferEnabled = $true
    PrebufferSeconds = 10
    PrebufferInMemory = $true
    Verbose = $true
}
$selectedCameras | Set-VmsCamera @props

<# OUTPUT
VERBOSE: Performing the operation "Changing PrebufferSeconds from 3 to 10" on target "Camera 1".
VERBOSE: Performing the operation "Saving changes" on target "Camera 1".
VERBOSE: Performing the operation "Changing PrebufferSeconds from 3 to 10" on target "Camera 2".
VERBOSE: Performing the operation "Saving changes" on target "Camera 2".
#>

Prompts for a camera selection and accepts the selection of camera groups or recording servers, and removes duplicate entries in the results just in case the same cameras are present in multiple groups or subgroups. Cameras are retrieved from the selected group(s) recursively.

Next, each camera is configured to use an in-memory pre-buffer of up to 10 seconds. All changes made are logged to the verbose stream so each configuration change made to each camera will be displayed in the console.

Example 3¶

$vmsCameraParams = @{
    Camera = Get-VmsCamera -Name 'Office Entrance'
    Coordinates = '45.4171601197572, -122.732137977298'
    Direction = 90
    FieldOfView = 180
    Depth = 15
    Verbose = $true
}

Set-VmsCamera @vmsCameraParams

<# OUTPUT
VERBOSE: Performing the operation "Changing CoverageDirection from 0.505555555555556 to 0.25" on target "Cam Lab Camera".
VERBOSE: Performing the operation "Changing CoverageFieldOfView from 0.125 to 0.5" on target "Cam Lab Camera".
VERBOSE: Performing the operation "Changing CoverageDepth from 37.49040000015 to 4.57200000001829" on target "Cam Lab Camera".
VERBOSE: Performing the operation "Saving changes" on target "Cam Lab Camera".
#>

A hashtable named $vmsCameraParams is defined with all the parameters needed to change the GPS location, direction, field of view, and depth of field for the camera(s) named "Office Entrance". The hashtable is then "splatted" into the cmdlet and because we included the Verbose switch, all changes made to the camera are logged to the console.

Note that if the settings already matched these values, there would be nothing logged to the console because no changes had to be made.

PARAMETERS¶

-Camera¶

Specifies one or more Milestone Configuration API camera objects such as those returned by Get-VmsCamera.

Type: Camera[]
Parameter Sets: (All)
Aliases:

Required: True
Position: 0
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-Coordinates¶

Specifies GPS coordinates in a "latitude, longitude" format where latitude and longitude are positive or negative numberic values with no alphabetic characters. For example, "45.4171601197572, -122.732137977298".

To remove the coordinates from a camera, you may set the value to $null or ''.

Type: String
Parameter Sets: (All)
Aliases:

Required: False
Position: 5
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-CoverageDepth¶

Specifies the depth of the camera's field of view in meters.

Type: Double
Parameter Sets: (All)
Aliases:

Required: False
Position: 12
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-CoverageDirection¶

Specifies the orientation of the camera as a 360-degree compass bearing expressed as a value between 0 and 1. For example, a value of 0 represents North while a value of 0.5 represents South, and 0.75 represents West. You can produce the right value by dividing the compass heading value, such as 270 degrees (East), by 360, for a value of 0.75.

Alternatively, you may choose to use the Direction parameter which allows for specifying a value in degrees between 0 and 360. If the Direction parameter is provided, it takes priority over CoverageDirection.

Type: Double
Parameter Sets: (All)
Aliases:

Required: False
Position: 8
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-CoverageFieldOfView¶

Specifies the angle of the field of view of the camera in degrees, expressed as a value between 0 and 1. For example, a value of 0.25 represents 90 degrees and a value of 0.5 represents 180 degrees. You can produce the right value by dividing the field of view in degrees, by 360.

Alternatively, you may choose to use the FieldOfView parameter which allows for specifying a value in degrees between 0 and 360. If the FieldOfView parameter is provided, it takes precedence over CoverageFieldOfView.

Type: Double
Parameter Sets: (All)
Aliases:

Required: False
Position: 10
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Depth¶

Specifies the depth of the field of view, either in meters, or in feet, depending on the region settings of the environment in which PowerShell is running. If PowerShell is running in a PC configured in a region of the United States, the value will be treated as a measurement in feet. In most other cases the value will be treated as a measurement of meters. To override the regional default or explicitly include the units in your script, you may use the Units parameter.

This parameter overrides the CoverageDepth parameter if that parameter is also provided.

Type: Double
Parameter Sets: (All)
Aliases:

Required: False
Position: 11
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Description¶

Aliases:

Required: False
Position: 3
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

Specifies that the camera should be enabled or disabled.

Type: Boolean
Parameter Sets: (All)
Aliases:

Required: False
Position: 4
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-FieldOfView¶

Specifies the field of view of the camera in degrees between 0 and 360. This parameter overrides the CoverageFieldOfView parameter if that parameter is also provided.

Type: Double
Parameter Sets: (All)
Aliases:

Required: False
Position: 9
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-GisPoint¶

Specifies the GPS coordinates of the camera in a custom format. The value is accepted as a string in the format "POINT EMPTY" to "un-set" the coordinates, or "POINT (X Y [Z])" where the elevation field "Z" is optional and not usually provided, X represents the longitude, and Y represents the latitude. It's important to note that this format reverses the standard "latitude, longitude" order because it is expressed internally in Milestone as a "point" with X/Y coordinates.

You may use the Coordinates parameter for a more user-friendly format for setting coordinates.
