Introduction: Meet the DS-2CD2547G2-LS — a compact 4 MP ColorVu mini dome

The Hikvision DS-2CD2547G2-LS is a fixed mini dome IP surveillance camera designed to deliver full-colour imaging around the clock. With a 4 MP sensor (2688 × 1520), a fast F1.0 2.8 mm lens and built-in white supplement light (ColorVu), this camera is aimed at installations that require excellent low-light performance, reliable weatherproofing and advanced onboard analytics. Its compact form factor, PoE support and ONVIF compatibility make it a practical choice for installers, integrators and technically minded DIY users.

Key features at a glance

• 24/7 full-colour imaging:Large-aperture F1.0 lens plus built-in smart white light for vivid colour in very low light.
• 4 MP resolution:2688 × 1520 at up to 25/30 fps with efficient H.265/H.264 compression.
• Smart analytics:Deep-learning features onboard, including human/vehicle classification, face capture and perimeter protection (line crossing, intrusion).
• Robust outdoor performance:IP67 weather rating and IK08 impact resistance for exterior deployments.
• Flexible connectivity and storage:PoE (802.3af) or 12 VDC, microSD local storage, NAS support and ANR to handle network outages.

Detailed specifications and benefits

The DS-2CD2547G2-LS uses a 1/1.8" progressive-scan CMOS sensor to produce sharp 4 MP images. The 2.8 mm fixed lens gives a wide field of view (approximately 112° horizontal), making it suitable for monitoring entrances, retail aisles, parking approaches and building perimeters. Crucially, the F1.0 aperture combined with the built-in white light enables full‑colour imaging down to 0.0005 Lux and 0 Lux when the white light engages — this is the ColorVu advantage versus traditional IR-based low-light cameras.

The camera supports H.265 and H.264 (including H.265+ / H.264+ optimisations) to reduce bandwidth and storage requirements without sacrificing detail. Triple streaming and region-of-interest (ROI) support allow you to prioritise bandwidth to critical areas of the scene. The shutter range and a 130 dB wide dynamic range (WDR) help the camera handle scenes with strong backlight or mixed lighting conditions.

Onboard deep-learning analytics include human/vehicle classification for more accurate event filtering, face capture for identification workflows and perimeter protection features such as line crossing and intrusion detection. These analytic capabilities reduce false alarms, simplify monitoring and support faster response times. The LS variant includes audio I/O and a built-in microphone for additional situational awareness.

Network compatibility is broad: ONVIF S/G/T, IPv4/IPv6 and HTTPS/TLS ensure interoperability with third-party VMS platforms and secure transmission. For storage the camera supports microSD cards (capacity depends on region/firmware) and NAS (NFS/SMB), and ANR helps protect footage during network outages. Power options include PoE (802.3af, class 3) for simple single-cable installations, or 12 VDC where PoE is not available. Typical power consumption is modest (~6.5–8 W), making it suitable for PoE switches and small installations.

Built for outdoor use, the DS-2CD2547G2-LS is IP67 rated for dust and water ingress and IK08 rated against impact. The compact footprint (Ø113.6 × 72.6 mm and ~400 g) makes it unobtrusive and easy to install under eaves or on walls and ceilings. Operating temperature ranges from -30 °C to 60 °C, covering most climates.

Use cases and scenarios where this camera excels

• Retail and commercial premises:ColorVu’s full-colour imaging is a major advantage in shops and malls where colour helps identify clothing, vehicles or distinguishing features. The analytic features reduce false alarms and help protect stock and entrances.
• Perimeter security for small to medium sites:For offices, warehouses and residential complexes, the combination of perimeter protection analytics and wide field of view provides effective coverage without needing multiple cameras.
• Parking lots and access control:The wide-angle 2.8 mm lens is ideal for monitoring approach lanes, and colour footage at night aids plate and vehicle colour recognition in many situations where IR would only produce monochrome images.
• Installations with limited infrastructure:PoE support simplifies deployment where power outlets are sparse. Local microSD storage and ANR provide resilience where network reliability is a concern.
• Discreet residential monitoring:Homeowners who want a weatherproof, vandal-resistant camera that preserves night-time colour details will find the mini-dome form factor attractive and discreet.

Comparisons with similar products

Traditional IR cameras rely on infrared illumination and deliver monochrome night images, which can make identification of colours and subtle details difficult. The DS-2CD2547G2-LS’s ColorVu system uses white supplemental lighting and a large-aperture lens to produce true colour images at very low light levels. For applications where colour identification at night matters (retail theft, vehicle identification, incident investigation), ColorVu is a clear advantage.

Higher-resolution cameras (e.g., 6–8 MP) can capture more detail at long distances but often require more bandwidth and storage. The 4 MP balance offered by this Hikvision model provides high-quality images with reduced storage and network demands, making it a practical choice for many sites where wide coverage and low-light performance are priorities over ultra-high resolution.

Mini domes are compact, less intrusive and generally offer better vandal resistance mounting options compared with bullets. The DS-2CD2547G2-LS’s IK08 rating and compact dome housing are well suited to public-facing and decorative settings where a discreet, robust look is preferred. Bullets may be chosen for long-range coverage or as a visible deterrent, but for many installations the dome’s form factor is the better fit.

Customer feedback and testimonials

Below are representative testimonials based on typical user experiences with ColorVu-style mini domes; these illustrate how different users benefit from the camera’s features.

• Retail manager:"We switched several entrance cameras to ColorVu and immediately noticed improved incident capture — colour makes it much easier to identify clothing and vehicle colours after hours. Installation was straightforward using PoE."
• Security integrator:"The DS-2CD2547G2-LS is compact and reliable. The analytics reduce false alarms for our customers, and ONVIF compatibility means we can integrate it into most VMS platforms without headaches."
• Property owner:"I wanted a weatherproof camera for the driveway that didn’t look bulky. The mini-dome is discreet and delivers surprisingly good night-time colour images. The microSD backup gave me peace of mind when our ISP had an outage."

Conclusion: Why choose the DS-2CD2547G2-LS?

The Hikvision DS-2CD2547G2-LS 4 MP ColorVu fixed mini dome strikes a strong balance between image quality, low-light colour performance and practical deployment features. Its F1.0 lens and built-in white light deliver true-colour imaging in conditions that would normally force IR cameras into monochrome. Combined with onboard deep-learning analytics, PoE convenience, robust environmental ratings (IP67, IK08) and flexible storage options, this camera is well suited to retail, commercial, residential and light industrial applications.

For projects that require accurate night-time colour, simplified network installation and reliable perimeter analytics without the storage and bandwidth demands of ultra-high-resolution devices, the DS-2CD2547G2-LS is an excellent choice. Its compact form factor, broad compatibility and practical performance make it a versatile option for installers and end users seeking dependable, all‑round surveillance coverage.
