The ROI (Region of Interest) feature in camera systems
The ROI (Region of Interest) feature in camera systems lets you define areas in the camera's field of view that will receive increased attention. This can be achieved in several ways:
- Higher resolution: in the defined area the image is rendered at higher resolution, making it easier to recognise details.
- Higher sensitivity: in the defined area the camera's sensitivity is increased, making motion detection easier even in poor lighting.
- Per-area camera settings: in the defined area you can adjust camera settings such as brightness, contrast and sharpness for an optimal image.
- Action triggers: after motion detection in the defined area the system can trigger further actions such as an alarm or operator alert.
Benefits of ROI
- Greater monitoring efficiency: focusing on important areas reduces operator fatigue and improves monitoring efficiency.
- Fewer false alarms: excluding less important areas from monitoring reduces false alarms.
- Higher security: focusing on critical areas allows timely response to security incidents.
ROI is a useful tool for optimising monitoring and improving security.
Examples of ROI use
- Building entrance monitoring: ROI is set on the door to make identifying people entering the building easier.
- Parking lot monitoring: ROI is set on parking spots to make detecting unauthorised vehicles easier.
- Production-line monitoring: ROI is set on critical sections of the production line to make problem detection easier.
