In this newsletter, we introduce the automatic ISP profile switching feature built into Seyeon Tech’s IP cameras. IP cameras are placed in environments far more complex than we often imagine—indoor and outdoor, bright sunlight and dark tunnels, forests and beaches, sunrise and sunset. Maintaining consistent image quality in these diverse conditions requires more than a single static ISP setting.

Therefore, the ISP (Image Signal Processor) profile of the camera must be automatically adapted according to changes in the environment.  For example, when lights turn off or the camera enters a tunnel, it must instantly switch to an appropriate ISP setting to maintain optimal image quality.  Seyeon Tech cameras are designed to actively adapt to such situations. 

Multiple ISP profiles can be configured according to conditions, and the camera automatically applies the optimal profile to ensure consistent, high-quality images.

Many conventional cameras only switch from color to black-and-white when transitioning from day to night.  However, since lighting, color temperature, and noise conditions differ greatly between day and night, using the same ISP profile leads to unavoidable image degradation. To overcome this limitation, Seyeon Tech cameras allow completely separate ISP profiles to be defined for daytime and nighttime.  For example, profiles for bright outdoor scenes and low-light indoor conditions are separately optimized/configured and automatically switched during day/night transitions.  But Seyeon Tech doesn’t stop at day and night. Our cameras support four fully independent modes: Day, Night, DI (Digital Input), and Motion. Each mode operates with its own ISP profile, and switching occurs automatically based on real-time triggers.

DI Mode, in particular, offers a highly flexible structure.  Profiles can be triggered by scheduled time slots, scene changes, or input from external devices such as sensors and alarm systems.  Upon detecting a trigger, the camera applies the DI-specific ISP profile and returns to the standard profile when the event ends. 

The following are the four operational modes supported by our system:

 Default (Day) Mode : This is the default profile applied during daytime under normal conditions.

 Night Mode  : Automatically activated when lighting or conditions indicate a transition to night.

 DI Mode (Digital Input)  : Triggered by external digital signals (e.g., sensor activation), this profile can respond to scheduled times, scene-based adaptation, or event-based inputs.

 Motion Mode  : Activated when motion is detected within a designated region of interest in the frame, allowing for enhanced detail and clarity.

This smart, automated profile switching structure ensures optimal image quality for various operational objectives and environments. It is a key differentiator in today’s evolving surveillance market.

This real-time, environment-sensitive switching system gives Seyeon Tech cameras an unmatched advantage over conventional models.  Unlike simple time-based switching, which lacks adaptability, our system focuses on event, sensor, and visual data-driven automation—true smart image processing at its core.
