FireTrack
Use the FireTrack module to receive immediate alerts on smoke and fire hazards in both indoor and outdoor environments.

How It Works
A neural network trained to recognize smoke and fire processes the video.
The network looks for the visual signs of smoke and fire. It produces a confidence score, the probability that the frames contain smoke or fire.
For smoke or fire to be detected, the smoke or fire must cover at least 2% of the frame.
The module detects only dense, highly opaque smoke that fully blocks the background. Smoke that dense is treated as a clear sign of a fire. Light haze and steam are ignored, so false alarms stay down.
The confidence score is compared with the threshold in Sensitivity to smoke or Sensitivity to fire. A lower sensitivity requires a higher confidence score before the module creates an event.
The module also compares how long the smoke or fire has been present with the minimum time set for that event.
When every condition is met, the module creates a Smoke or Fire event.
Computational Complexity
The algorithm is rated 3.5 on a 5-point complexity scale. Average CPU usage is about 70%, and the load can vary with video resolution and the processor.

How to Receive Smoke and Fire Alerts
Smoke and fire alerts require immediate response from emergency services.
- Ensure that cameras monitoring fire-prone areas meet the system requirements.
- Enable the FireTrack module and configure detection for smoke and/or fire.
- Configure an alarm monitor with Analytics modules > FireTrack > Smoke/Fire enabled.
Set Up Smoke Detection
Configure FireTrack parameters under CALIBRATION and ADDITIONAL SETTINGS.
- Region of interest: defines the area of the frame to analyze (highlighted in green). By default, the full frame is used.
To move a vertex, drag it with the cursor.
To delete a vertex, double-click it.
To add a vertex, double-click on an edge.
To move the entire region, drag it from inside the selection.
- Assign priority levels for Smoke and Fire events.
- Sensitivity to fire (0–1): lower values require a larger fire area to trigger a Fire event.
- Sensitivity to smoke (0–1): lower values require higher smoke density to trigger a Smoke event.
- Smoked for longer than … sec: defines how long smoke must persist to be detected.
- On fire for longer than … sec: defines how long a fire must persist before triggering an alert, helping reduce false positives from short-lived events.
When enabled, FireTrack automatically generates the Smoke and Fire events.
