6MP High-Definition Image Quality
The camera provides up to 6MP resolution at 3200 × 1800, giving surveillance footage significantly more detail than standard Full HD cameras.
The main stream can deliver 3200 × 1800 at up to 20 fps, while 2688 × 1520 supports up to 25/30 fps, depending on configuration.
This makes the camera suitable for monitoring entrances, shops, offices, homes, corridors and other areas where clear video detail is important.
Smart Dual Light Night Vision
A major advantage of the IPC-HDW1639T-A-IL is its Smart Dual Light technology.
The camera combines IR illumination and warm light in a multi-core lighting system. IR can be used for discreet nighttime monitoring, while warm light can provide visible illumination and color imaging when required.
Both illumination systems have a maximum range of 30 meters according to Dahua's specifications.
30m IR + 30m Warm Light
The camera provides:
IR: up to 30m
Warm Light: up to 30m
This makes it particularly useful for nighttime surveillance around entrances, building exteriors, retail locations and residential properties.
Human Detection
The DH-IPC-HDW1639T-A-IL supports human detection, allowing the camera to identify human targets and help filter events triggered by non-human movement.
This can make security monitoring more focused and reduce unnecessary alerts compared with basic motion detection.
Built-in Microphone
The camera has a built-in microphone, allowing compatible surveillance systems to capture audio together with video.
This is useful for locations where both visual and audio information can improve security monitoring.
Smart H.265+ Video Compression
The camera supports Smart H.265+ and Smart H.264+ encoding.
Dahua's smart encoding technology is designed to improve encoding efficiency and reduce storage and transmission requirements while maintaining useful image quality.
This can be particularly valuable when multiple cameras are connected to the same NVR and storage capacity needs to be optimized.
Advanced Image Enhancement
The camera includes several image-processing features:
DWDR for challenging lighting conditions
3D NR for noise reduction
HLC for strong light sources
BLC for backlight compensation
ROI for prioritizing important areas
Image rotation modes for different installation scenarios
These functions help maintain useful surveillance footage across different lighting environments.
2.8mm and 3.6mm Lens Options
The DH-IPC-HDW1639T-A-IL uses a fixed-focal M12 lens and is available with 2.8mm or 3.6mm focal length options.
The 2.8mm version provides approximately:
Horizontal: 110°
Vertical: 58°
Diagonal: 132°
The 3.6mm version provides approximately:
Horizontal: 91°
Vertical: 46°
Diagonal: 110°
The 2.8mm option is better when a wider field of view is preferred, while 3.6mm provides a more focused view.
