Hikvision DS-2CD1T47G2H-LIUF/SRB 4MP ColorVu Bullet Camera

The Hikvision DS-2CD1T47G2H-LIUF/SRB combines advanced imaging, intelligent security detection and active warning features to deliver reliable surveillance during the day and at night. Its distinctive red and blue flashing alarm lights, built in speaker and microphone make it particularly suitable for properties that require both security monitoring and immediate deterrence.

4MP High Resolution Imaging

The camera captures video at 2560 × 1440 resolution, providing detailed surveillance footage for identifying activities and monitoring important security areas. Its 4MP resolution offers improved image detail compared with standard 2MP cameras.

ColorVu Technology for Nighttime Imaging

Hikvision ColorVu technology uses a large F1.0 aperture to capture more available light, improving colour imaging in low light conditions. This helps preserve useful visual details, including clothing and vehicle colours, when sufficient ambient or supplementary illumination is available.

Smart Hybrid Light Technology

The camera combines infrared and white-light illumination for flexible nighttime surveillance. It supports three operating modes:

• Infrared Mode: Provides discreet black-and-white surveillance.

• White Light Mode: Uses visible illumination for colour nighttime footage.

• Smart Mode: Can switch from infrared to white light when a relevant target is detected.

Its supplementary lighting system supports illumination up to 50 metres under suitable conditions.

Red and Blue Strobe Light Alarm

A distinguishing feature of the /SRB variant is its red and blue flashing light alarm. When configured detection events occur, the camera can activate flashing lights to attract attention and discourage unauthorized activity. This feature is especially useful for entrances, perimeter areas, parking facilities and restricted locations.

Built In Two Way Audio

The camera includes a built-in microphone and speaker, allowing users to listen and communicate through compatible monitoring software. This is useful for speaking to visitors, issuing warnings or responding to security incidents remotely.

Intelligent Human and Vehicle Detection

The camera can distinguish people and vehicles from other moving objects, helping reduce unnecessary alerts caused by environmental movement. This improves the relevance of motion notifications and helps security personnel focus on important events.

120dB Wide Dynamic Range

The camera supports 120dB WDR, helping balance bright and dark areas in challenging lighting conditions. This is useful for building entrances, loading bays and areas exposed to strong sunlight.

Efficient H.265+ Video Compression

H.265+ video compression helps reduce bandwidth and recording storage requirements, improving efficiency when used with compatible NVR systems.

IP67 Outdoor Weather Protection

Its IP67-rated housing protects against dust and water, making it suitable for outdoor installations.
