DW MEGApix Ai and Blackjack Ai Analytics

DW MEGApix Ai cameras integrate advanced deep learning capabilities directly at the edge, enabling real-time object detection and event alerts. Camera video streams are actively processed and analyzed in real-time by the embedded Ai analytic engine as they are sent to the recording server, increasing analytic efficiency, reducing latency and network load, while preserving video quality.

DW Blackjack Ai Servers leverage server-side analytic processing to enhance video intelligence and can be deployed to accompany existing security setups and standard DW Blackjack recording servers. Like MEGApix Ai cameras, video analytics are processed centrally to reduce the load on edge devices. As a result, video streams from preexisting (non-Ai) cameras can be analyzed by the Ai server, offering a cost-effective solution to elevate existing DW Spectrum systems in manageable stages, without needing to replace standard camera hardware.

 

By being able to analyze video footage in real-time, you can implement intrusion detection for sensitive areas, log and manage ANPR license plate detections, and automate your security setup. Further enhance surveillance efficiency and minimize unnecessary alerts by also creating parameters to filter out ambient elements like foliage or vehicle traffic, which may be irrelevant to your security needs.

This article will outline how to create and configure the various analytic detection zones, non-detect zones, and detection lines with DW Ai analytic products.

 

Supported/Affected Devices:

  • DW MEGApix Ai Cameras
  • DW Blackjack Ai Servers

 

Detection Zones and Analytic Rules

Through Deep Learning technology, intelligent analytics use scene recognition and advanced object recognition for motion tracking and event rules. DW Ai products come equipped with 12 built-in algorithms for customizable surveillance setups, tailored to specific security needs.

Analytic rules can be created within the camera’s web interface through the DW Spectrum Client or using a web browser.

 

**NOTE: To view analytic rules in the camera’s preview window, the Burnt-in Annotation feature must be enabled within the camera.

  • Decrement: select an analytic rule that will decrease from the tally.
  • Occupancy: set the counter rule from the available list, which when triggered will add to the counter.
  • Trigger Condition: define the counter threshold that will cause an event to be triggered.
  1. [Optional] Clicking the Reset Counter button will reset the tally number to zero. This action cannot be undone once performed.
  2. [Optional] In the Event Actions section, select the type of Event Notification and Action Rule that will occur when the rule’s trigger condition occurs.
  3. Click the Save button to apply the counter to the camera.

 

Creating a Non-Detect Zone Rule

A Non-Detect Rule will designate an area that the camera will ignore object detection and motion, which can prove useful for mitigating false alarms. Some common scenarios include when there is background motion from nearby roads and ambient movement from trees and foliage.
