Hikvision DS-2CD2T47G3-LIS2UY/SL(2.8mm) 4MP Hybrid ColorVu Fixed Bullet Camera

The Hikvision DS-2CD2T47G3-LIS2UY/SL is a 4MP PoE bullet camera with either a 2.8mm or 4mm fixed lens. It features ColorVu 3.0 technology, and a built-in dual microphones & speaker for added 2-way audio security. In addition, an integrated strobe light and audio alarm provides a powerful deterrent against would-be intruders. The anti-corrosion body offers excellent reliability and longevity, particularly in harsher environments such as the seaside.

Available in black or white.

ColorVu 3.0

 ColorVu 3.0 elevate video security to unprecedented levels, delivering improved image quality, more intelligent functions, better audio capabilities, and enhanced product design and materials. All ColorVu 3.0 cameras feature smart hybrid light technology which integrates Infrared and white lights to give the best of both worlds, providing colour night-time images

AI Powered WDR

Hikvision has introduced the innovative AI WDR (Wide Dynamic Range) in its ColorVu 3.0 range, allowing both the bright and dark areas of an image to be blended naturally. Bright areas are not overexposed, while details in dark areas are not lost. In addition, the AI WDR enables the device to determine whether to automatically turn on or off WDR according to the brightness of the environment, without the need for manual adjustments.

AcuSense 3.0

Hikvision AcuSense 3.0 advanced video surveillance technology combines AI and deep learning algorithms to deliver smarter, more accurate security monitoring. The dual algorithm upgrades in AcuSense 3.0 greatly improve the accuracy rate while effectively reducing the false alarms caused by lights hitting stationary cars at night and reacting to the true source of the event notification.

AcuSense 3.0 also incorporates AcuSearch, a feature that was historically only found in intelligent recorders. This allows users to focus on specific targets of interest with just one click, improving overall search efficiency. ‘Smart Search’ settings allow users to draw rule boxes or intrusion lines at the location of an event to quickly filter and easily identify targets entering a particular area. The ‘Slice Playback’ function enhances video retrieval still further by enabling users to visually locate the segments they want to replay. These features work together to improve overall search efficiency, helping users to quickly and easily find the information they need.

 Audio 2.0: Crystal-clear audio with intelligence

In addition to upgrading image and intelligence, the Network Cameras with ColorVu 3.0 also bring users a new audio experience. The Audio 2.0 provides better sound reception and speaker effects. The arrayed dual-mic design ensures excellent noise reduction, delivering enhanced vocal clarity and improving overall audio quality. The integration of a Smart PA Speaker extends sound coverage, amplifying the warning effects of alerts and facilitating greater two-way audio communication. With Audio 2.0 the cameras can better adapt to larger and more complex scenarios which have higher audio requirements.

DORI

DORI - Recommended operational range of the camera

DORI is a standardized system that provides a clear framework for evaluating the effectiveness of CCTV cameras. It is based on the European standard EN 62676-4, which defines specific criteria for detecting, observing, recognizing, and identifying objects or individuals within a camera's field of view. For more information on understanding the DORI metrics, please read our blog article here.
