How can I get Forensic search task rules transferred into the camera for further live alarm purpose?

Question

What is it required for offline troubleshoot in case of false alarm in the IVA rules from cameras?

Answer

The scope of this article is used when you’ve made improvements to your system after analyzing a recording. Here's how it works step-by-step:

1. Recording and Playback: You start by recording footage, then play it back in the BVMS.

2. Forensic Search: You perform a forensic search to review specific events or situations in the footage.

3. Adjust VCA Rules: During the forensic search, you modify the VCA (Video Content Analysis) rules to fine-tune the detection parameters. This helps reduce false alarms by refining the system’s sensitivity or behavior.

4. Improved Configuration: After these adjustments, your system’s detection settings are more accurate, resulting in fewer false alarms.

5. Copy to Camera: Once you're satisfied with the improved configuration, you apply it by copying the settings to the camera to make the changes permanent for future recordings.

This process helps you optimize your system's performance over time.

The VCA task editor can be used for easy analytic configuration or for troubleshooting.

In case of false alarm in the IVA rules from one of the cameras, to troubleshoot offline (without traveling to the site) the following is required:

1. Exported video using VRM Export Wizard

• How to export VRM recordings of cameras & convert them to mp4-file (VRM eXport Wizard 2.0)?
• How to export VRM recordings of cameras & convert them to mp4-file (VRM eXport Wizard 2.10)?

2. Copy the script with the VCA Task Editor from Config Manager

-Paste the script to a notepad text file

3. Send 1&2 to the system integrator or the person who will help to improve the IVA config.

Note

Export with native format from BVMS does not have IVA metadata.

Also, .mov or .MP4 or .wave etc format do not have IVA metadata.

Yes! An installer doesn’t need to travel to customer's site for fine tuning the configuration, when a Camera Analytics task brings false alarms.
