Stop/Start recording all the cameras

Hey

I’m looking for plugin example to stop or start recording all the cameras

Note: when the record is in stop I’m still need to be able to run playback

Thanks

I suggest you create a rule that when a user-defined event is triggered you begin recording on all cameras belonging to a group (and uses another event to stop).

You then develop a plugin that trigger the user-defined events on UI button or other criteria you implement.

As inspiration for the plugin explore the ConfigAccessViaSDK sample; the Trigger button. This is not a plugin sample but you can use the same code in your plugin.

It is important to note that a rule can start and stop recording, but if another rule or user action has started recording you cannot stop the recording by applying a rule.

Thank you

I take a look on ConfigAccessViaSDK example and I see that in the example using send massage TriggerCommand but not using Stat/StopRecordingCommand massage so I don’t understand how they in the example control on the recording

also I want to know if there is any way to go overall the Camera and the Screen Recorder in the systems so I can send for each one of them Stop or Start record massage

Allow me to explain.

You said you wanted to start all the cameras. What I suggest is that you create a rule that will start and stop recording in all cameras. This is an alternative to sending StartRecordingCommand to each camera which could be many depending on the size of your installation.

If you do not know how to create the rule please consult the help (F1) in the Management Client, or ask again.

You can see how to use the StartRecordingCommand if you explore the VideoViewer sample. https://doc.developer.milestonesys.com/html/index.html?base=samples/videoviewer_sample.html&tree=tree_2.html

As you indicate this would be the way to go if you want control of the individual camera and not all cameras in on go.

Hey

Thank you!

by you recommended if prefer to create a rule

So I try to take a look on ConfigAccessViaSDK example

first I don’t exactly understand what the meaning of ConfigAccessViaSDK application so maybe it’s will be easy to find what in need from the example if I understand what the application do - so I will be happy to get a little explain

Second I will like to get more explain or reference to explain about ‘rule’, how I create rule that effect from outside ? (in may case I using socket massage UDP)

6

So the ConfigAccessViaSDK does a lot of stuff but the Trigger button in that sample is the method that I wanted you to notice. The Trigger button will, if you have a user-defined event picked, trigger the user-defined event.

The central code you need to use (and you do not need much else) is: (item being the user-defined event)

EnvironmentManager.Instance.SendMessage(
  new VideoOS.Platform.Messaging.Message(
    VideoOS.Platform.Messaging.MessageId.Control.TriggerCommand), item.FQID);

I am glad I had the chance to explain further, do not hesitate to ask again if it does not play for you right away..

OK

and how I create a rule ?

Thank you

I try to create a rule from the XProtect Management Client application

But it’s look like something wrong

When I try to klick on each rule in the list (was in the rule list some building rules) the XProtect Management Client application crash…

Thank you

the like to fix the crash was very useful

I don’t find to create rule from kind ‘StartRecordingEvnt’ in the list of the rule

where I can find that rule ?

12

You need to create the events and the rule in the Management Client

I believe this can be of guidance..

Hey

I try to create my Event (from 3 type in the list : ‘User-defined Event’ ‘Analytics Event’ ‘Generic Event’) in all of themes in ‘Step 2: Conditions’ I don’t find options to add ‘start recording immediately on RecordOnRuleCamerasGroup’

I have only the options : ‘Within selected time’ Outside selected time in’ ‘Within the time period’ ‘Day of week is’ ‘Event is from’

Can you help me?

Thank you

Hey

I found, I just skip on that step…

Thank you!

Hey

So I chose to use ‘User-defined Events’ - I understand that that event base on string

Now I’m try to send the Event from my XProtect Smart Client plugin

how I can send my specific User-defined Event ?

16

If you have the Item that is your user-defined event you just use it.

Note that the ConfigAccesViaSDK should be an eye opener to the “configuration” and how it is structured, so you might revisit that sample.

If you do not have the Item, you find it, I suggest you look at the CameraStreamResolution sample, FindCamera method, but change it to use Kind.TriggerEvent instead of a Kind.Camera

https://doc.developer.milestonesys.com/html/index.html?base=samples/camerastreamresolution.html&tree=tree_2.html

Alternatively use VideoOS.Platform.Configuration.GetItemsBySearch

https://doc.developer.milestonesys.com/html/index.html?base=miphelp/class_video_o_s_1_1_platform_1_1_configuration.html&tree=tree_search.html?search=getitem

17

So I try to create an item with two way (GetItemsByKind and GetItemsBySearch)

                   List<Item> list = Configuration.Instance.GetItemsByKind(Kind.TriggerEvent);

                   SearchResult Result;

                   List<Item> list1 = Configuration.Instance.GetItemsBySearch("UDEventStopRecord", 10, 10, out Result);

In the both of them I don’t find my event in the lists…

18

The two samples I have mentioned both illustrate that the configuration is like a tree, so you probably miss using the GetChildren method when you use GetItemsByKind.

The ConfigAccessViaSDK builds a tree to visualize this, the FindCamera method implements a very simple recursive routine that can help.

However the GetItemsBySearch method should give you a common list so your list1 should contain the Item in the list.

might be better yet.. https://developer.milestonesys.com/s/question/0D53X00006Sow5dSAB/how-to-get-the-available-cameras

hey

I try to copy that get item samples

"SearchResult result;

List listCam = Configuration.Instance.GetItemsByKind(Kind.Camera);

List list2 = Configuration.Instance.GetItemsByKind(Kind.TriggerEvent);

List list1 = Configuration.Instance.GetItemsBySearch(“UDEventStopRecord”, 10, 10, out result);

List allUserDefinedEvents = Configuration.Instance.GetItemsBySearch(Kind.TriggerEvent.ToString(), 10, 5, out result);"

Into CameraStreamResolution example , in FindCamera method

and all of them work good

but in my plugin it’s not working at all

It’s look like the Configuration.Instance not working well

In CameraStreamResolution example the Configuration.Instance.ServerName member is ‘DESKTOP-B7NRPQ7’ (as the host name)

But in my plugin Configuration.Instance.ServerName member is empty

Did I miss something in the initialization of Configuration or something else ?

Thank you!
