CVEDIA-RT for VCA cameras

CVEDIA-RT can work along with an embedded version of NX Witness, NX Meta, Wisenet WAVE, DW Spectrum or Piko as a VCA camera plugin.

Installing VCA plugin

After you installed a compatible VMS in the camera, open camera's admin panel and go on:

  1. Setup -> System -> Plug-in -> Select file
  2. Select the .enc file you downloaded from https://rt.cvedia.com

  3. After the VMS restarts, you should see CVEDIA-RT as a plugin:

    CVEDIA-RT VCA plugin

  4. It's suggested to disable the native VCA analytics to free some resources:

    Disable VCA Analityics

Configuration

Connecting to the VMS Server

  1. Download and install the Nx Witness client from this link. You may download a differerent flavor of NX, but the following steps do not change.

    Tip

    If you're running a different flavor of NX the setup process is the same, except for the client you will download.

  2. Run the Nx Witness application, a New System with pending status will show up:

  3. Click on it, then click Setup New System

Adding a new device

You need to have at least one camera added before using our analytics.

  1. Locate the list of servers on the left side of the application, and right-click on the one we just connected (eg. CVEDIA-RT) to add a new camera.

  2. Paste the URL of your camera or RTSP device into the address bar, enter login, password, and port if required, set as default if needed and when ready, click on search.

    Tip

    If you have IP cameras connected to your network, you can use the "Subnet Scan" option.

  3. Locate the device to be added to the list of found devices.

  4. Click on the Add all Devices button.

  5. Once ready, the camera will be shown as added and the add devices window can be closed to return to the main window of Nx Witness.

  6. Note that a new device is now shown underneath the server name on the left side of the screen.

  7. Double-click on the new device to open the viewer.

Info

For more information on the camera setup in Nx Witness application, please check the official manual: NX Witness User Manual

Enabling the Plugin

  1. Right-click on the video stream and select the camera settings option.

  2. Navigate to the plugins section of the camera settings window and enable the CVEDIA-RT plugin and click apply.

    Warning

    As shown in the red banner at the bottom of the screen, the analytics will work only when the camera is being viewed or when the recording is enabled.

Activation

You must activate a license to be able to run the analytics, we offer trial licenses in some installs, contact sales if you want to buy commercial licenses.

Activating

You can activate a license after you enable CVEDIA-RT Plugin (see the following chapter on Enabling the RT plugin) in the VMS device settings.

You can then use the last page in the left panel to activate the license: NX Plugin Activation

Deactivating

Once a license is activated, it gets bound to the specific device on which the plugin is running (the NX Witness server).

If you need to replace the device, you should deactivate the license before using it on a different device.

Simply click the Revoke key button in the Licenses window (see image above).

Activating

To activate the CVEDIA-RT Plugin license, you may need to access the System Administration settings of the Nx Witness application. From there, you can add the license for the plugin:

  1. Click on the top-left icon with 3 horizontal lines, to access the System Administration window.

  2. Go to the Plugin section and select the CVEDIA-RT plugin if it's not already selected.

  3. Insert the license key in the first available slot and cick the Apply button.

    Please wait a few seconds until the Status field is updated.

    The Status field will inform you that the license is valid and active. In case of errors, it will inform you of the failing reason, such as network issues, invalid license key, etc...

Deactivating

Once a license is activated, it gets bound to the specific device on which the plugin is running (the NX Witness server).

If you need to replace the device, you should deactivate the license before using it on a different device.

To deactivate a license is enough to remove it from the text field and click the Apply button. Wait a few seconds until the Status field is updated.

Multiple licenses

Each license is configured with a maximum number of concurrent cameras where the analytics will run.

If you need to increase this limit, you can obtain a new license with the additional streams and activate it.

Analytics

Enabling

Once you activated RT and added a license you can enable analytics.

  1. From the left menu, you can now configure the analytics of your choice.

  2. Configure one of the analytics. For example draw an area in the Intrusion Detection.

  3. Click the OK to save the settings.

  4. Go to the OBJECT tab on the top right to preview the detected objects:

  5. To generate events, you need to define the camera rules in NX Witness. Right-click on the camera and click on Camera Rules, and add a new rule based on Analytic Events.

  6. Monitor the events in the events tab.

Recording Events

If you create a rule that has a Bookmark as an action, you can easily jump to the recorded event.

Don't forget to enable the recording in the Camera Settings. This requires an Nx Witness license, but you can easily activate a trial one.

Once you activate the recording, you can set days and hours. To save on space you can choose the Objects Only or Objects + Low-Res modality.

Configuring Analytics

Each analytics allows you to configure some operational options, such as the area of the line used to trigger events, and some other related parameters.

All the analytics offer the ability to specify for each area or line what type of objects to detect between Person, Animal, Vehicle, or Unknown motion.

An analytic is active only if at least one area or one line is defined.

Multiple Analytics

You can enable multiple analytics at the same time. This will not impact on the performance of the system.

Inspecting

Once CVEDIA-RT plugin is enabled, you can check if it's running and which hardware it's using.

First enable Show statistics in the plugin Expert Mode:

Then, open the camera and go into Objects tab within NX, and you will see a large info panel:

This panel shows as follows:

  • Engine version: CVEDIA-RT engine version
  • Plugin: NX integration plugin version
  • Solution: CVEDIA-RT solution version
  • AI frame-rate: Should be always above 10 for analytics to perform correctly
  • AI latency: miliseconds spent doing inference, should be less than 100 ms for analytics to perform correctly
  • Camera frame-rate: Camera source frame rate, should always be above 10 for analytics to perform correctly
  • Run time: Runtime of CVEDIA-RT instance
  • # frames processed: Number of frames processed by our analytics
  • Accelerator: Accelerator(s) type and ultilization percentage (when available)
  • AI Model: Model(s) in use and accelerator(s) used to run it, some examples of accelerators are:
    • rknn: Running on Rockchip NPU
    • tensorrt: Running on NVIDIA GPU
    • openvino.CPU: Running on Intel CPU
    • openvino.GNA: Running on Intel GNA
    • openvino.GPU: Running on Intel GPU
    • hailo: Running on hailo
