Motion Event PTZ Presets with the Axis M5000-G in exacqVision

Overview

The Axis M5000-G PTZ camera is a multi-sensor camera containing three stationary wide-angle lenses around the circumference of the camera body and one center-mounted PTZ lens. This guide is intended to help users automate the positioning of the PTZ lens upon events, such as motion detection.

Requirements

  • Axis M5000-G PTZ camera, with firmware 11.10.61 or higher
  • exacqVision Server 24.09 or higher

NOTE: While this article is written specifically with the M5000-G PTZ in mind, the setup of Event Linking to reposition PTZ cameras based on the motion detection from other sensors, and even other cameras, can be used with any capable devices.<br><br>

Camera Configuration

  1. Log into the camera’s web browser interface.<br><br>
  2. Configure the initial user credentials as required, if you have not already done so.<br><br>
  3. Open the PTZ menu. You may configure the PTZ presets within the camera on the Preset Positions screen, or choose to configure presets within exacqVision at a later stage.
    <br><br>
  4. If desired, configure the range of motion for the PTZ turret on the Limits screen within the camera. These settings cannot be configured within exacqVision. See the device’s help file or manual for details on setting PTZ limits.
    <br><br>
  5. The Motion tab within the PTZ settings configures the behavior of the camera during motor movement of the PTZ turret. Motion detection may be configured within the Video Motion Detection application under the Apps menu.
    <br><br>

Connecting the Camera to exacqVision

Use the AXIS VAPIX option from the Device Type menu when adding the Axis M5000-G PTZ camera.

Refer to the exacqVision Client User Manual or watch one of our videos on how to Add IP Cameras for the steps to connect the camera to your exacqVision Server.<br><br>

Motion Detection

If you chose not to configure motion detection zones within the camera, do this now for use in the next steps.

  1. Expand the left-hand navigation tree under Camera Recording.<br><br>
  2. Select the sensor to be configured. When adding the M5000-G PTZ camera to exacqVision, each sensor appears individually on the navigation tree as a separate camera.<br><br>
  3. On the Camera Settings page for the selected sensor, use the Display tab to change the Name. You may find it helpful to identify each sensor and which one is the PTZ. This will be useful in later steps.
    <br><br>
  4. Use the settings on the Motion tab to define the motion detection regions within the sensor’s field of vision. You may need to adjust the sensitivity, percentage, and time to trigger settings to best suit your installation environment.
    <br><br>

PTZ Presets

When adding the M5000-G PTZ camera to exacqVision, each sensor appears individually on the navigation tree as a separate camera with the PTZ turret as the first one. A preset is a saved position and field of view that can be used to quickly point the PTZ lens to a specific region of interest such as a display or locked cabinet.

  1. Expand the left-hand navigation tree under Camera Recording.<br><br>
  2. Select the PTZ sensor.
    <br><br>
    NOTE: Due to this camera reporting to exacqVision that it is a PTZ camera all sensors will display a Mechanical PTZ tab, but there are no motors associated with the non-PTZ sensors.<br><br>
  3. On the Camera Settings page for the PTZ sensor, select the Mechanical PTZ tab, then choose the Presets tab beneath it.
    <br><br>
  4. If you configured PTZ Presets within the camera they will be shown in the Presets panel.<br><br>
  5. Create new Presets by using the Pan/Tilt and Zoom controls to position the camera’s field of view as you’d like, then press the New button to Name your preset before selecting the Apply button to save your changes. Presets may also be removed by selecting them from the list and pressing the Delete button. <br><br>
  6. In the example below, we have created a preset to display a file cabinet after creating a motion detection region for this area on Sensor 3. This may just as easily be focused on a specific entry way, display case, or any other object of interest.
    <br><br>

Using Event Linking to Move the PTZ on Motion Events

PTZ presets may be activated manually by those monitoring exacqVision, but can become more powerful tools when automated. In the next steps you will configure exacqVision to direct the PTZ turret of the M5000-G camera to preset locations when motion is detected by the stationary lenses. You may even choose to activate a preset when motion is detected by other cameras nearby.

  1. From the left-hand navigation tree in the exacqVision Client, select Event Linking.<br><br>
  2. Begin by pressing the New button near the bottom of the window.<br><br>
  3. From the Event Type panel on the left, select Video Motion.<br><br>
  4. Use the Event Source panel to locate and select the first of your stationary camera sensors.<br><br>
  5. From the Action Type panel in the center-right of the window, select PTZ Preset.<br><br>
  6. Using the Action Target panel, select the name of a preset configured for a region within the sensor’s field of view.<br><br>
  7. Press Apply to save your changes.<br><br>
  8. You’ve now configured the system so that when motion is detected by the first sensor it will reposition the PTZ turret to examine an area within that sensor’s field of view with greater detail.
    <br><br>
  9. Press the New button again to repeat Steps 3-6 for each sensor and preset combination.
    <br><br>
  10. The following images show the Live view of all four sensors from the camera in Live viewing mode. The stream from the PTZ turret sensor is shown in the upper-left corner and moves to the file cabinet when motion is detected.
    <br><br>
    <br><br>

If you have a secondary camera nearby configured for motion detection or AI driven Object Classification, you may also select these using the Event Types (Video Motion or Analytics), then select the other camera from the Event Source window. Event Linking may combine other event types as well to take a PTZ Preset action, such as Serial Profiles to position a PTZ lens towards a cash register during sales transactions, or Input Triggers to position the lens towards a door when opened. See our Event Linking Video for more information, or refer to the Related Articles section below.

Recording different resolution or frame rates on event

Description

Some users may desire to record a different resolution or frame rate from a camera when an event such as motion or an analytic is triggered. Reasons for this vary by site, but often comes down to wishing to record a lower amount of data when very little is happening, but they require high frame rates or high resolution recordings for forensic playback.

In the steps below, we step through creating a secondary stream but configuring them with different settings and schedules. These steps are examples and you will need to adjust the settings for your site’s needs. Mix and match resolution, frame rate, or recording format as desired.

<br>

Setup Steps

  1. Navigate to the Camera Settings page for the camera you wish to configure.<br><br>
  2. Configure the settings for your first stream using the Recording tab on the bottom half of the page. It’s best to use this primary stream for your highest resolution and frame rate settings simply because most cameras provide fewer options for secondary streams.
    <br>In this example, our primary stream is configured for a resolution of 3840 x 2160 (4K/8MP) and an image rate of 25 fps.<br><br>
  3. Assuming your camera supports Multistreaming, select a new Context from the Multistreaming settings and click the Add Stream button.
    <br><br>
  4. After pressing the Add Stream a new sub-stream, or child stream, will appear on the system navigation tree to the left, nested beneath the primary, or parent, stream you just configured. The Camera Settings page should update to display the settings for this stream.
    <br><br>
  5. Configure the Format as needed, then configure the Resolution and Image Rate desired for your lower end stream.
    <br>In this example, the stream is configured for a resolution of 1024 x 576 and an image rate of just 10 fps.<br><br>
  6. Select the high resolution, high frame rate primary stream from the system tree and choose the Schedule tab. In this example, we’re going to configure the high resolution, high frame rate stream to only record on an analytic, in this case person detection.<br><br>
  7. Highlight the entire schedule grid and change these from the default of Motion to None. Apply your change.
    <br><br>
  8. Select the lower resolution, lower frame rate, secondary stream from the system tree, then select the Schedule tab. You could choose to set it to Free Run recording for continuous recording, or highlight the entire schedule and change it to Motion recording.
    <br><br>
  9. The low resolution, low frame rate stream will record based on the schedule configured on the Schedule tab. We need to tell the system when to record the higher resolution, high frame rate stream. Click the New button.<br><br>
  10. Navigate to the Event Linking node on the system tree.<br><br>
  11. We’re triggering off an analytic in this example, but you may use any Event Type you wish, such as Motion or an Input Trigger. We select Analytics, then choose the Enter Rule analytic, previously configured on the camera, from the Event Source panel.<br><br>
  12. Our Action Type will be Record Video.<br><br>
  13. The Action Target will be the high resolution, high frame rate primary stream.
    <br><br>
  14. Returning to the Schedule for this primary stream, we see the red corner flags are set indicating hours of the day in which our configured Event Link will record this camera stream. By default this will occur for all hours and days. Event Linking Source Groups could be used to configure specific days and hours to record on this event.
    <br><br>
  15. Save your configuration by selecting the Apply button.<br><br>
  16. Your configuration is complete and ready for testing. When performing a search you may search for recordings from either, or both, the primary and secondary streams but will likely rely on the primary stream for those high resolution or high frame rate forensic investigations of incidents.<br><br>
  17. Repeat these steps for other cameras where you may want the similar recording behavior.<br><br>

Artificial Intelligence Object Classification Event Triggers Filling OS Drive

Description 

We have found that event links based on triggers from AI Object Classification events flood the eventPI database resulting in the OS drive being filled in a short amount of time. Periodic unexpected crashes, system reboots and increased memory usage have resulted. This happens when the amount of AI metadata captured in the eventPI database in a single day exceeds the available free space on the drive.

The following exacqVision Server log entries confirm when this issue is occurring.

Product 

  • AXIS Object Analytics
  • Hanwha AI-based object detection
  • Illustra AI Object Classification
  • exacqVision Server [All versions]

Solution

Update the exacqVision Server and Client to version 23.09 or higher.

Once updated, utilize the ‘Maximum Days to Keep Bounding Box Metadata’ control. Details on this feature may be found in Maximum Days to Keep Bounding Box Metadata Explained

Analytics not Shown as Alarm on Event Linking

Description 

If you are setting up an event linking using an Analytic Event Type this will not show as alarm in the status window.

Product 

  • exacqVision Client
  • exacqVision Server

Steps to Reproduce 

  • Select Event Linking.
  • Add a New Event and select Analytics.
  • Select your Event source, Action Type and Action Target.
  • Click Apply.

Expected Results 

The Status will change from Off to Alarm

Actual Results 

The Status always stays Off

Solution

This is as designed, many analytics triggers happen so fast that the Status on the Event Linking page never appears to change or it does so for only a split second.

Here is one way to verify it is working.

  • Change the Action Type to Log Event

Setting up Email Notifications to send a Start and a Stop email when the event starts and ends.

When setting up email notifications to work with a IP Camera Connection event there is setting in the Notifications to send on the event start and end.

Once the Email Profile has been tested and confirmed to be working we need to set up 2 rules for this to work properly

  1. Event Linking

To set up the trigger to allow the notification to work we must set up an Event linking event.
In this Example we are using a single camera to to send an email when the camera disconnects and reconnects to the server. The email profile will send out an email that will show the start of the event and the end of the event with a Start and End status in the email that is receive.

The event rule should be set similar to the picture above.

Event Type: IP Camera Connection
Event Source: Is the camera that you want to monitor.
Action Type: Notify (the Email Notifications)
Action Target: The Email Profile Created in the Notifications section. Alert Emails.

Notification Email Message Profiles

To configure your email profile Page correctly to send the notifications with a start and an end see the picture below.

When setting up the Email Message Profile Page there are 2 things we need to make sure are selected from the menu options.

1.Make sure to Select the WHEN drop down menu and select Alarm Starts and Ends. (If you want only on start select Alarm Start)
2. In the Add Field drop down menu select EVENT STATE and a Date format.

When the event is triggered the email profile will send an email out on the start of that event and then at the end of that event.
