DAHUA DH-IPC-HFW2849TL-S-PRO 8MP CCTV WizColor Camera 

DAHUA DH-IPC-HFW2849TL-S-PRO Singapore

8MP 4K WizColor 24/7 Colour • WizSense AI • Bullet IP Camera • CCTV Repair & Upgrade

The DAHUA DH-IPC-HFW2849TL-S-PRO is an 8MP 4K WizColor fixed-focal bullet network camera designed for high-quality colour surveillance in very low-light environments. It combines a large 1/1.8" CMOS sensor, ultra-bright F1.0 aperture, warm-light illumination, WizSense human/vehicle classification, SMD Plus, built-in microphone, PoE and IP67 outdoor protection.

It is a strong upgrade option for factories, warehouses, landed properties, condominiums, commercial buildings, car parks, loading bays, shops and perimeter CCTV systems where useful colour information at night is important.

8MP 4K Full Specifications

Dahua's current product page confirms these specifications; older datasheet revisions can differ slightly, so firmware/hardware revision should be checked for replacement projects.

WizColor — 24/7 Colour CCTV

The major advantage of the DH-IPC-HFW2849TL-S-PRO is WizColor.

Conventional IR CCTV often changes to black-and-white at night. WizColor instead combines a large 1/1.8" sensor, F1.0 aperture, image processing and warm supplemental lighting to retain substantially more useful colour information in low-light scenes. Dahua positions WizColor specifically for low-light colour imaging.

Colour evidence can help operators distinguish details such as:

Vehicle colour • Clothing colour • Bag colour • Object colour • General scene details

However, “24/7 colour” does not mean the camera can produce perfect daylight-quality colour in complete darkness without illumination. Available ambient or built-in supplemental light still matters.

Large 1/1.8" Sensor + F1.0 Lens

Low-light CCTV performance is not determined by megapixels alone.

This model combines:

1/1.8" CMOS sensor

• F1.0 aperture
• WizColor processing
• Warm supplemental light

The current Dahua specification lists minimum illumination down to 0.0004 lux @ F1.0.

This architecture is particularly useful where conventional high-resolution cameras produce excessive noise, motion blur or lose useful colour after dark.

2.8mm / 3.6mm / 6mm — Choose the Correct Lens

This is a fixed-focal camera, not a motorized zoom camera.

Current Dahua specifications list three lens choices:

2.8mm — 110° horizontal FOV
Best for wide areas, entrances and short-distance coverage.

3.6mm — 93° horizontal FOV
A useful general-purpose balance between width and distance.

6mm — 57° horizontal FOV
Narrower coverage with greater pixel concentration on more distant targets.

Therefore, lens selection should be done before installation. You cannot remotely zoom a 2.8mm version into 6mm after installation.

Warm Light Up to 50m

The latest Dahua specification differentiates illumination distance by lens:

2.8mm → up to 20m
3.6mm → up to 30m
6mm → up to 50m

using built-in warm light.

This is more precise than simply advertising every version as “50m warm light.”

Actual usable illumination also depends on mounting height, target reflectivity, surrounding lighting and scene geometry.

WizSense AI — Human & Vehicle Detection

The DH-IPC-HFW2849TL-S-PRO includes Dahua WizSense intelligent functions.

Its perimeter protection supports:

Intrusion Detection
Tripwire Detection

with human and vehicle classification.

For example:

Human crosses restricted boundary
→ Camera classifies target
→ Tripwire rule triggered
→ Event recorded
→ Compatible NVR/app can present the alarm event

This is substantially more useful than relying only on basic pixel-based motion detection.

SMD Plus

SMD Plus further improves intelligent motion-event filtering. Dahua lists SMD Plus as a standard feature of this model.

In a correctly designed system, human/vehicle classification can reduce irrelevant motion events and make recorded-event searching more efficient.

For best results, pair the camera with a compatible Dahua Smart NVR, because Dahua specifically supports refined intelligent search and event extraction when the camera works with an appropriate Smart NVR.

4K Recording — Important Frame-Rate Detail

The camera records:

3840 × 2160 8MP → maximum 20fps

or

2688 × 1520 4MP → up to 25/30fps.

Therefore, it should be advertised as:

“8MP 4K @ up to 20fps”

—not 4K 30fps.

Built-In Microphone

A built-in microphone provides real-time audio security in addition to video.

This can be useful for entrances, warehouses, loading areas and commercial premises where audio provides additional incident context.

Recording audio is subject to applicable privacy, notification and organizational requirements.

IP67 Outdoor Protection

The camera has an IP67-rated metal housing, making it suitable for many outdoor installations.

For a reliable outdoor installation, the complete system should still include appropriate:

Weatherproof junction box • Cable gland • Cat6 cable • PoE switch • Surge protection where required

An IP67 camera does not automatically make an exposed RJ45 joint waterproof.

CCTV Repair & Upgrade Singapore

For an existing Dahua system with no picture, intermittent video, poor night image, water-damaged connections, HDD errors or obsolete cameras, replacing only the camera may not solve the underlying problem.

A proper upgrade should check:

Existing camera → Cabling → RJ45 termination → PoE voltage/power → PoE switch → NVR compatibility → HDD condition → Network → Router → Mobile App

For an older 2MP or 4MP CCTV system upgrading to this 8MP 4K camera, the existing NVR should be checked for:

8MP camera support
4K recording capability
H.265 compatibility
Incoming bandwidth
Decoding/display capability
HDD capacity
PoE capability

An old NVR may display a new camera but still limit recording resolution, decoding performance or AI functionality.

10 FAQs

1. Is DH-IPC-HFW2849TL-S-PRO an 8MP 4K camera?
Yes. Maximum resolution is 3840 × 2160, or 8MP 4K.

2. Does it provide colour video at night?
Yes. It uses Dahua WizColor technology with an F1.0 lens, large 1/1.8" sensor and warm supplemental illumination for low-light colour imaging.

3. Is it an infrared camera?
This specific WizColor model uses warm-light illumination rather than being marketed as a conventional IR bullet camera.

4. Does it support human and vehicle detection?
Yes. Intrusion and tripwire functions support human/vehicle classification.

5. Does it support SMD Plus?
Yes.

6. Does it have a microphone?
Yes, a built-in microphone is provided.

7. Can I install a 256GB microSD card?
Yes. Dahua specifies support for up to 256GB microSD.

8. Is it PoE?
Yes. It supports 12VDC or PoE, simplifying network-camera installation.

9. Can it replace my existing 2MP Dahua camera?
Potentially, but the existing NVR, PoE/network infrastructure, recording resolution, bandwidth and decoding capability must first be checked. Do not assume every older Dahua NVR fully supports an 8MP WizColor/WizSense camera.

10. Where can I buy, repair or upgrade Dahua CCTV in Singapore?
