DS-2CD2047G3-LI2UY/SL 2.8mm ColorVu Strobe

The G3-generation 4MP ColorVu active-deterrent IP bullet

The Hikvision DS-2CD2047G3-LI2UY/SL 2.8mm is the active-deterrent version of the G3-generation 4MP ColorVu IP bullet. Same refined ColorVu sensor and AcuSense AI as the standard DS-2CD2047G3-LIY 2.8mm, with the addition of built-in white-light strobe and audible siren that fire on AcuSense-confirmed human or vehicle activity in the configured detection zones.

The right call for the priority outdoor positions on premium residential properties: the front gate of a smallholding, the main entrance of a freestanding home, and any position where the camera needs to do more than just record (it needs to make intruders go away). Combined with AcuSense filtering, the strobe fires only on confirmed real-person activity, not on cats and shifting branches.

What this camera is actually good at

• 4MP resolution with refined G3 ColorVu sensor.
• 40m hybrid IR/white-light illumination.
• Built-in active siren and white-light strobe with AcuSense-driven triggering.
• 130dB WDR for extreme-contrast scenes.
• Array microphone for audio capture.
• AcuSense AI filtering all alerts and strobe triggers to confirmed human and vehicle activity.
• 2.8mm wide-angle lens for situational gate and entrance coverage.
• IP67 weather-sealed housing.

The strobe needs proper configuration

Active-deterrent cameras that fire their strobe at every cat are worse than no strobe at all. Detection zones drawn precisely, AcuSense sensitivity calibrated for the specific environment, schedule rules ensuring the strobe only fires when armed, and live testing with real-person walk-through all matter critically. We do that configuration work as standard on every install.
