Product Overview
Combining full-colour night vision with AcuSense deep learning, the DS-2CD2547G2-LS is a 4MP Gen2 outdoor mini dome camera suited to locations where both after-dark colour detail and intelligent event filtering are priorities. Built with a F1.0 super-aperture lens and a high-sensitivity sensor rated to 0.0005 Lux, the camera captures colour-accurate footage at night using onboard white LED illumination, achieving 0 Lux performance with the LEDs active. AcuSense classification distinguishes people and vehicles from irrelevant motion such as animals, rain, and foliage, reducing nuisance alerts significantly. The compact mini dome housing carries an IP67 ingress rating and IK08 vandal resistance, making it appropriate for exposed outdoor mounting on eaves, soffits, building facades, and covered entry points. Available in 2.8mm and 4mm fixed lens options, the DS-2CD2547G2-LS also includes an audio and alarm interface, with a built-in microphone for on-site audio capture.
Key Capabilities
24/7 Full-Colour Night Vision
The F1.0 super-aperture lens and high-performance sensor work with onboard white LEDs to produce colour footage in complete darkness. Rated to 0.0005 Lux with light off and 0 Lux with LEDs active, this camera captures usable colour detail that standard IR cameras cannot provide after dark.
AcuSense Human and Vehicle Classification
Powered by deep learning, AcuSense separates people and vehicles from other motion triggers such as animals, leaves, and changing light. This reduces unnecessary alerts and allows footage to be filtered by category, cutting review time significantly for operators and end users.
130 dB Wide Dynamic Range
A 130 dB WDR rating allows the camera to handle scenes with extreme contrast, such as a doorway backlit by bright daylight. Both the subject and the bright background remain visible without the image being washed out, which is particularly useful for entry and exit points.
IP67 and IK08 Protection
Full dust ingress protection and weatherproofing under IP67 make this camera suitable for direct outdoor exposure. The IK08 vandal resistance rating adds physical robustness for mounting in accessible areas such as covered entries, car park structures, and building perimeters.
H.265+ Compression
H.265+ compression reduces file sizes compared to older H.264 systems, lowering storage demands on NVRs and reducing bandwidth requirements across the network. This is particularly relevant for 4MP cameras recording continuously over extended retention periods.
Best For
- Outdoor Entry and Exit Monitoring: The 130 dB WDR and F1.0 lens handle backlit doorways and transition zones where contrast is challenging, while AcuSense filters out irrelevant motion triggers at high-traffic access points.
- Sites Requiring After-Dark Colour Detail: Locations such as car parks, retail forecourts, and residential driveways benefit from white LED full-colour night imaging where identifying clothing colour, vehicle colour, or signage after dark is operationally important.
- Compact Dome Installations in Exposed Locations: The mini dome profile and IK08 rating suit eave, soffit, and wall-mount positions where a discreet housing is preferred but the camera must tolerate physical contact and weather exposure.
- Installations Needing Audio Capture: The built-in microphone and audio/alarm interface on the -S variant support on-site audio recording and alarm input integration without requiring additional hardware at the camera position.
Why Choose the DS-2CD2547G2-LS
The DS-2CD2547G2-LS sits at the intersection of full-colour imaging and intelligent filtering, which separates it from standard 4MP outdoor domes that offer only one of these features. A basic 4MP dome delivers resolution but relies on IR lighting that strips colour from night footage. A standard ColorVu camera delivers colour but without AcuSense, it cannot filter human and vehicle events from background motion. The DS-2CD2547G2-LS combines both, and the Gen2 sensor improves on earlier ColorVu models with better low-light sensitivity at 0.0005 Lux. The IK08-rated mini dome housing keeps the footprint compact for installations where a large turret or bullet camera would be visually intrusive. Lens choices of 2.8mm and 4mm allow installers to match the field of view to the specific coverage zone. Available at Security Wholesalers, this model suits commercial and residential projects where after-dark colour accuracy and reduced false alert volumes are both required.
Buyer Decision Tips
Lens Selection: The 2.8mm lens produces a 112-degree horizontal field of view, which suits wider spaces such as car parks, open yards, and building facades where broad coverage from a single mounting point is the priority. The 4mm lens narrows to 95 degrees horizontal and extends detection range (77m detection versus 58m at 2.8mm), making it better suited to corridors, driveways, and approaches where the camera is covering a more defined line of sight. Confirm the coverage zone before ordering as the lens is fixed and cannot be adjusted after installation.
White LED vs. IR Illumination: ColorVu uses white LEDs to produce full-colour night footage. This means the camera emits a visible warm glow at night, which is noticeable to people in the area. In some applications this is a deterrent benefit, but in covert or low-profile monitoring scenarios where you need the camera to be unobtrusive at night, an IR-based camera would be more appropriate. Plan for this before selecting the DS-2CD2547G2-LS for sensitive locations.

Ideal Use Cases
Retail Forecourts and Car Parks
Full-colour night imaging via white LED illumination captures vehicle and clothing colour in low-light conditions, providing operators with footage that is actually useful for identifying incidents after dark without relying on greyscale IR imagery.
Building Entry and Exit Points
The 130 dB WDR handles the contrast between dark interiors and bright outdoor backgrounds at doorways. AcuSense filters motion events so that only people and vehicles trigger alerts, reducing nuisance notifications from shadows, light changes, and non-relevant movement.
Residential Driveways and Gate Areas
The 4mm lens option provides a 77m detection range and 95-degree horizontal coverage, appropriate for monitoring a driveway approach or gate entry where the camera needs to cover a defined corridor rather than a wide open space.
Covered Walkways and Undercover Areas
The compact mini dome form factor and IK08 vandal resistance make the DS-2CD2547G2-LS well suited to undercover areas such as building walkways, loading bays, and covered parking structures where the camera may be mounted at low height and is vulnerable to contact.
Sites with High False Alert Volume
Outdoor environments with animals, vegetation, or variable weather frequently generate high volumes of motion-triggered recordings with standard cameras. AcuSense classification on the DS-2CD2547G2-LS allows the system to log and alert only on human and vehicle targets, making monitoring more manageable for staff.
Choosing the Right Model
- Choose this model if: You need 4MP outdoor dome coverage with full-colour night vision and AcuSense AI filtering in a compact IK08-rated housing, particularly where after-dark colour identification of people and vehicles is operationally important.
- Choose a different model if: The installation requires covert or low-visibility night operation, as the white LEDs emit a visible glow that can be seen by people in the area. An IR-based AcuSense dome would be more appropriate in those scenarios. If longer detection range or a varifocal lens is required to frame a specific scene from a greater distance, a varifocal dome or bullet camera would provide more flexibility than this fixed-lens mini dome.
FAQs
- What is the difference between the 2.8mm and 4mm lens options on the DS-2CD2547G2-LS?
The 2.8mm lens gives a 112-degree horizontal field of view and a 58m detection range, making it better for wider spaces where broad coverage from one mount point matters. The 4mm lens narrows to 95 degrees horizontal but extends detection to 77m, suiting corridors, driveways, and approaches where the camera is monitoring a more focused line of sight. The lens is fixed, so confirm coverage requirements before ordering. - Does the DS-2CD2547G2-LS use infrared or white LED lighting at night?
This camera uses white LED illumination as part of Hikvision’s ColorVu system, not infrared. This means night footage is captured in full colour rather than greyscale. The LEDs produce a visible warm glow that can be seen by people nearby. The camera is rated to 0.0005 Lux with the LEDs off and 0 Lux with them active. - What does AcuSense actually do on this camera?
AcuSense uses deep learning to classify detected motion as either a human, a vehicle, or neither. Events involving people or vehicles can trigger alerts and be tagged for fast search, while other motion sources such as animals, rain, tree movement, and insects are filtered out. This reduces the volume of irrelevant alerts and makes event review considerably faster compared to standard motion detection. - Is the DS-2CD2547G2-LS suitable for outdoor installation?
Yes. The camera carries an IP67 ingress protection rating, which covers full dust protection and protection against water immersion. The IK08 vandal resistance rating indicates the housing can withstand a measured impact force. It is appropriate for eave, soffit, wall, and ceiling mounting in exposed outdoor positions including areas subject to rain and direct weather exposure. - Does this camera support audio recording?
The DS-2CD2547G2-LS includes a built-in microphone for on-site audio capture. The -S variant also provides an audio and alarm interface for connecting external devices. Note that recording audio in Australia may be subject to state and territory surveillance legislation. Confirm compliance requirements with a qualified installer before enabling audio recording features. - What NVR or recorder is compatible with the DS-2CD2547G2-LS?
As a Hikvision IP camera, the DS-2CD2547G2-LS is compatible with Hikvision network video recorders that support the ONVIF protocol. For full AcuSense functionality including human and vehicle search filters, a Hikvision NVR with AcuSense support is recommended. Confirm compatibility with your specific NVR model before purchasing. Security Wholesalers stocks a range of compatible Hikvision NVRs if you need guidance on pairing.
