Liquid Leak Detection · Practical Guide
Operating Conditions
Plan camera views, nighttime illumination, detection zones and rain inputs for your industrial or commercial site.
Start with what the camera can see
LLD uses computer vision to detect puddles, spray and visible vapor. Frame the areas you want to monitor and define interest zones and exclusion zones in the application.
Use camera presets to organize views where appropriate. A focused view area retains pixel density on the monitored area, helping improve detection.
Provide illumination at night
Detection continues at night with artificial lighting or the camera’s near-infrared (NIR) illumination. Review the actual monitored views after dark to check that the scene remains clearly visible.
Do not treat nighttime support as operation in unlit darkness. This guide does not claim a separate NIR performance benchmark.
Balance sensitivity against nuisance alarms
High sensitivity prioritizes quick detection with a higher chance of false and nuisance alarms. Average balances detection speed and nuisance-alarm reduction. Low takes longer to detect while prioritizing alarm accuracy.
Choose settings for each monitored area and use Advanced settings when more control is needed. Puddle Advanced Alarm Progression is not a spray or visible-vapor feature.
Account for wet weather
Rain data helps LLD account for wet weather when managing alarms. A rain sensor connected directly to the camera’s I/O ports is the recommended local connection where available.
An external I/O module is another physical-sensor route. A weather-service API requires internet access from the camera. Choose the connection that fits the site rather than assuming outdoor deployment includes a rain-data source.
