Dahua Starlight IP Dome Motorised 2.7–13.5mm
The Dahua DH-IPC-HDBW2431RP-ZAS-27135-S2 is a high-performance 4MP Starlight IP Dome Camera designed for reliable security monitoring in residential, commercial, and industrial environments. Featuring a 1/3” CMOS image sensor, this motorised varifocal dome camera delivers sharp, detailed images with excellent low-light performance.
For efficient recording and storage, the camera supports H.265 compression, Smart H.264/H.265, and ROI technology, reducing bandwidth and storage requirements without compromising important video details.
4MP High-Definition Surveillance
The 4MP image sensor provides detailed video with resolutions up to 2560 × 1440 at 25/30 fps. It can also support up to 2688 × 1520 at 20 fps, delivering enhanced image clarity for monitoring entrances, buildings, commercial areas, and other security-sensitive locations.
Motorised Varifocal Lens
The 2.7–13.5mm motorised varifocal lens allows flexible adjustment of the camera’s field of view, making it easier to achieve the desired coverage without physically repositioning the camera.

Starlight & 40m IR Night Vision
Designed for around-the-clock surveillance, the camera combines low-light imaging technology with integrated IR illumination. Its IR LEDs provide a maximum night vision distance of 40 metres, helping capture useful footage after dark.
Advanced Image Enhancement
Multiple image-processing technologies work together to improve video quality in difficult lighting conditions:
- WDR for high-contrast scenes
- 3D DNR for reducing image noise
- HLC for controlling strong light sources
- BLC for improving backlit subjects
- Rotation mode for flexible installation
- Digital watermarking for video protection
Smart Detection & Security Alerts
The Dahua camera provides intelligent detection functions to help identify important events and reduce the need for constant manual monitoring. Intrusion and tripwire detection can be configured for specific surveillance areas.
Abnormality Detection
The camera can identify several system and video-related abnormalities, including:
- Motion detection
- Video tampering
- No SD card
- SD card full
- SD card error
- Network disconnection
- IP conflict
- Illegal access
- Voltage detection
Efficient H.265 Video Compression
With H.265 and Smart H.264/H.265 compression, the camera is designed to reduce video file sizes, bandwidth consumption, and storage requirements. ROI support also allows important areas within the image to receive greater encoding priority.
Flexible Storage & Connectivity
The camera supports a Micro SD card up to 256GB, providing convenient local video storage. It also includes 1 alarm input and 1 alarm output, along with 1 audio input and 1 audio output for integration with compatible security and audio devices.
PoE & Reliable Outdoor Protection
The DH-IPC-HDBW2431RP-ZAS-27135-S2 supports both 12V DC and PoE power, offering flexible installation options. PoE can simplify deployment by carrying power and network connectivity through a single compatible Ethernet cable.
With IP67 weather protection, the camera is designed to withstand dust and water exposure. Its IK10 impact-resistant housing provides additional protection against physical impact, making it suitable for demanding surveillance locations.
