Night surveillance often requires a compromise. Visible illumination provides color details but may disturb people or attract attention. Infrared illumination remains discreet but produces monochrome images.

TRASSIR PRO DualLight cameras eliminate this trade-off.

Smart illumination for changing conditions

Using intelligent dual illumination, cameras can operate discreetly in IR mode and automatically switch to color imaging when an event occurs.

This means operators receive:

• Discreet surveillance during normal operation
• Color evidence during incidents
• Reduced complaints caused by permanently active white light
• Better visual identification of people, vehicles, and objects

Real-world scenarios

Retail stores and shopping malls

During business hours, cameras provide overview monitoring and audio recording. After closing time, IR illumination maintains surveillance while LED illumination activates only when a person enters a monitored area.

Benefits:

• Better incident investigation
• Improved identification of individuals
• Reduced false alarms

Manufacturing facilities

Perimeter and production area monitoring often requires reliable night visibility without constant bright illumination.

DualLight cameras provide:

• Continuous monitoring after dark
• Event-based color video
• Human and vehicle classification
• Reduced light disturbance

Office buildings and business centers

Common areas, reception zones, elevators, and entrances benefit from discreet monitoring combined with clear visual evidence when events occur.

Benefits:

• Better visitor monitoring
• Improved security investigations
• Audio and video evidence from a single device

Municipal and public infrastructure projects

Parks, schools, hospitals, and public facilities often require reliable surveillance while minimizing unnecessary light exposure. DualLight technology allows operators to maintain visibility without permanent white-light illumination.
