Product Overview
For outdoor installations at building entrances, shopfronts, walkways, and driveways where colour scene detail matters after dark, the DS-2CD2147G2-L delivers 4MP ColorVu imaging in a weatherproof dome housing. Unlike infrared cameras that produce greyscale footage at night, this camera uses a built-in white light LED with a 30m illumination range to capture full-colour video around the clock, including in very low ambient light down to 0.0005 Lux. Featuring AcuSense deep learning detection, it classifies motion events as human or vehicle activity, which reduces the volume of non-relevant alerts triggered by animals, shadows, or foliage. Built with H.265+ compression and 130 dB wide dynamic range, it maintains usable image detail across scenes with mixed lighting. This model has no built-in microphone, making it suited to installations where visual monitoring is required without onboard audio capture.
Key Capabilities
24/7 Full-Colour Imaging
The built-in white light LED illuminates scenes up to 30m in full colour. At 0.0005 Lux sensitivity, the camera captures usable colour footage in near-darkness without switching to greyscale, making it far more useful for identifying clothing, vehicle colour, and other scene details at night.
AcuSense Human and Vehicle Detection
Deep learning classification separates human and vehicle movement from other motion sources. This reduces the frequency of non-relevant motion events at outdoor locations like shopfronts and driveways, where passing animals, trees, or shifting shadows would otherwise generate constant alerts.
4MP Resolution with 130 dB WDR
Four-megapixel output provides enough detail for practical identification at entrances and walkways. The 130 dB wide dynamic range handles high-contrast scenes, such as a brightly lit shopfront entrance with a darker background, by balancing exposure across the frame.
H.265+ Compression
H.265+ encoding reduces file size and bandwidth usage compared to older compression formats. This means longer recording history on the same storage and lower network load, which is useful in multi-camera installations where storage and bandwidth are shared across the system.
No-Microphone Dome Design
This variant has no built-in microphone, making it suited to environments where audio recording is not permitted or required. The weatherproof dome housing is low-profile and ceiling or wall mountable, fitting discreetly into outdoor-facing building spaces without drawing attention.
Best For
- Shopfronts and Retail Entrances: The 2.8mm lens covers wide entry areas, while AcuSense classification filters vehicle and pedestrian activity from general motion, reducing notification fatigue for business owners.
- Residential Driveways and Gates: Full-colour night vision captures vehicle colour and plate area context in low-light conditions, providing more useful footage than a standard infrared camera at the same price point.
- Covered Walkways and Building Perimeters: The low-profile dome housing mounts neatly to soffits and building eaves, and the 130 dB WDR manages the uneven lighting typical of covered outdoor corridors.
- Installations Requiring Video-Only Monitoring: Where privacy regulations or site policy prohibit audio recording, the no-microphone configuration provides a compliant option without sacrificing image quality or detection capability.
Why Choose the DS-2CD2147G2-L
The DS-2CD2147G2-L sits in the Gen2 ColorVu range, which means it combines AcuSense deep learning detection with full-colour white light imaging in a single outdoor dome unit. A basic motion-detection camera at a lower price point will produce greyscale night footage and generate alerts on any movement including wind-driven objects. The DS-2CD2147G2-L instead filters motion events by human and vehicle classification and maintains colour imaging down to 0.0005 Lux, giving installers and end users footage that is genuinely more actionable. The 130 dB WDR also handles backlit entry scenes that would cause blown-out or silhouetted images on cameras with narrower dynamic range. Available at Security Wholesalers, this model is stocked for installers who need a capable outdoor dome without the premium cost of higher-tier AI feature sets.
Buyer Decision Tips
No Microphone – Check Your Requirements First: This model has no built-in microphone. If the installation requires audio capture alongside video, a separate microphone-equipped variant of this camera is available. If the site has legal or policy restrictions on audio recording, such as a common area covered by tenant or consumer privacy rules, this no-microphone version is the appropriate choice. Confirm your audio requirements before ordering to avoid a return or exchange after installation.

Ideal Use Cases
Retail Shopfront Entrances
The wide 2.8mm field of view captures the full width of a shopfront entry. AcuSense filters vehicle and pedestrian events separately, and full-colour night imaging means footage taken outside trading hours still shows clothing colour and other identifiable detail.
Residential Driveways
White light illumination out to 30m covers a standard residential driveway or gate approach in colour. AcuSense vehicle detection triggers recording specifically on vehicle movement, reducing unnecessary footage from ambient motion sources.
Building Entry and Lobby Approaches
The 130 dB WDR manages the contrast between a lit interior and a darker outdoor approach visible through a glass entry. The dome housing mounts flush to soffits and canopies at building entries without protruding hardware.
Covered Outdoor Walkways
Covered walkways often have inconsistent or no artificial lighting after hours. The ColorVu white LED provides its own consistent illumination in these areas, and the low-profile dome form factor suits ceiling-mounted installation under awnings or pergolas.
Audio-Restricted Surveillance Zones
Common areas, stairwells, and shared outdoor spaces in residential or commercial buildings may have audio recording restrictions. The no-microphone configuration of this model provides 4MP colour imaging and smart detection without any onboard audio capture.
Choosing the Right Model
- Choose this model if: You need a weatherproof outdoor dome with full-colour night vision, AcuSense human and vehicle detection, and no built-in microphone – particularly for entrances, driveways, or covered walkways where audio recording is not required or permitted.
- Choose a different model if: The installation requires built-in audio capture alongside video – a microphone-equipped variant of this camera is available and should be selected instead. If the location requires a longer illumination range than 30m, a camera with a higher-power white light or an infrared model with extended range would be more suitable for that specific distance.
FAQs
- Does this camera have a built-in microphone?
No. The DS-2CD2147G2-L is the audio-free variant of this camera. It has no built-in microphone and does not record audio. If your installation requires onboard audio capture, a microphone-equipped variant is available separately. Check the product listing for the link to the microphone version before ordering. - What colour is the night footage from this camera?
This camera produces full-colour footage at night using its built-in white light LED. It does not switch to greyscale. At very low ambient light levels down to 0.0005 Lux, the sensor continues to produce colour images, and with the LED active it operates at 0 Lux. This applies to all hours of the day, giving consistent colour output across day and night conditions. - What is the white light range on this model?
The built-in white light illuminator has a stated range of 30m. This is sufficient for most residential driveways, shopfront entries, and covered walkways. For longer approaches or larger open areas requiring coverage beyond 30m, a different model with a more powerful illuminator or a longer-range lens would be more appropriate. - What does AcuSense do and how does it work on this camera?
AcuSense is Hikvision’s deep learning classification system. On the DS-2CD2147G2-L, it analyses motion events and determines whether the source is a human or a vehicle. Events that do not match either category are treated as lower-priority. This reduces the number of recording events and notifications triggered by non-human movement such as animals, shadows, or wind-driven objects at outdoor locations. - Is this camera suitable for mounting under an eave or on a soffit?
Yes. The dome housing is designed for ceiling and soffit mounting and the low-profile form factor suits covered outdoor locations such as eaves, undercover entries, and building overhangs. The weatherproof construction handles exposure to rain and dust, making it appropriate for outdoor positions that are sheltered but not fully enclosed. Available through Security Wholesalers, this model is regularly used in exactly these installation types. - What does the DORI range mean for this camera at 2.8mm?
DORI describes what the camera can achieve at different distances. At 2.8mm, the DS-2CD2147G2-L has a Detection range of 58m, an Observe range of 23m, a Recognise range of 11m, and an Identify range of 2m. In practical terms, subjects can be detected at 58m, and recognition of distinguishing features such as facial detail is achievable within approximately 11m under suitable lighting conditions.
