Detailed specifications and benefits
The DS-2CD2347G3-LI2UY packs a broad set of technical specifications tailored to outdoor surveillance. Below is a concise breakdown of the cameras major subsystems and the practical benefits they bring.
- Sensor:1/1.8" progressive-scan CMOS delivering 4 MP (2688 20) resolution. Benefit: higher pixel count and a larger sensor area improve detail and low-light sensitivity compared with smaller-sensor 2 MP units.
- Lens:Fixed 4 mm, F1.0 (approx. 95.2 horizontal field of view). Benefit: the fast F1.0 aperture gathers substantially more light, supporting vivid colour at low lux levels and enabling broader coverage with one camera.
- Minimum illumination:Colour imaging down to 0.0001 Lux (AGC on), and complete 0 Lux with supplemental light. Benefit: reliable identification and situational awareness in near-dark conditions when combined with the built-in lighting.
- Video codecs:H.265 / H.264 with Hikvision enhancements. Benefit: efficient compression reduces bandwidth and storage costs while maintaining quality.
- Frame rate:Up to 25/30 fps at full 4 MP resolution. Benefit: smooth motion capture for people and vehicles.
- Dynamic & noise handling:130 dB WDR, 3D DNR, BLC/HLC, EIS. Benefit: clear images in scenes with bright backlighting, glare, or night noise.
- Smart Hybrid Light:Integrated white light plus IR (850 nm), effective to 30 m with selectable modes. Benefit: preserves colour when needed or uses IR for covert viewing, and white light can assist recognition at night.
- Deep-learning analytics:Person/vehicle classification, face capture, line crossing, intrusion, region enter/exit. Benefit: fewer false alarms and more relevant alerts for security teams.
- Audio:Built-in arrayed dual-microphone available on certain variants. Benefit: audio context can help with incident assessment and verification.
- Network:ONVIF (S/G/T), IPv4/IPv6, HTTPS, RTP/RTSP, 802.1X. Benefit: integrates with a wide range of NVRs, VMS platforms and enterprise networks.
- Storage:MicroSD up to 512 GB, NAS (NFS, SMB/CIFS), ANR supported. Benefit: local failover recording if the network is interrupted and flexible retention options.
- Power:PoE IEEE 802.3af (max ~11 W) or 12 VDC (max ~8.5 W). Benefit: simplified cabling with PoE and compatibility with legacy 12 VDC supplies.
- Operating range:-30 C to 60 C. Benefit: dependable operation in harsh climates.
- Ingress protection:IP67 and NEMA 4X anti-corrosion rating in a metal housing. Benefit: dust-tight, waterproof performance and corrosion resistance for coastal or industrial sites.
- Physical:Compact turret form factor (Ø138.3 mm × 115.4 mm) at about 750 g. Benefit: discreet, easy-to-mount design that fits many standard surveillance installations.
Benefits in real-world terms
Taken together, these specifications create a camera that excels where colour detail at night, accurate alarms and durable outdoor performance matter. Specific advantages include:
- 24/7 colour identification:ColorVu technology plus the F1.0 lens mean human-recognizable colours can be preserved in very low light, helping identify clothing, vehicle colour and other forensic details that B/W images lack.
- Intelligent alarm filtering:Deep-learning person/vehicle detection reduces nuisance alarms from trees, shadows or small animals and focuses operator attention on meaningful events.
- Flexible lighting modes:Choose white-light illumination for visible, deterrent lighting or IR for covert observation depending on site requirements.
- Cost-effective installation:PoE simplifies deployment (single cable for power and data) and H.265 compression lowers recurring bandwidth and storage expenses.
- Reliability outdoors:IP67/NEMA 4X rating and a rugged metal body resist weather and corrosion for long-term service life.
Use cases and scenarios where the camera excels
The DS-2CD2347G3-LI2UY is particularly well suited to the following applications:
- Perimeter and fence-line protection:The combination of long-range lighting, deep-learning perimeter analytics (line crossing, intrusion) and 24/7 colour capture improves detection and identification at property boundaries.
- Retail exteriors and storefronts:Colour retention at night aids in identifying suspects and vehicles in criminal incidents, while white-light mode acts as a visual deterrent to theft or vandalism.
- Car parks and driveways:The wide field of view, vehicle classification and hybrid lighting support both situational awareness and post-event investigations.
- Industrial and coastal sites:NEMA 4X anti-corrosion protection and a wide operating temperature range help ensure reliable operation in harsh, salty or chemically aggressive environments.
- Residential communities and gated entrances:Accurate person/vehicle detection and optional face capture can improve access control workflows and reduce false alarms for security staff.
How it compares with similar products
When evaluating this camera against alternatives, there are a few key differentiators to consider:
- ColorVu vs IR-only cameras:Many entry-level outdoor cameras revert to black-and-white IR images at night. The ColorVu approach retains colour information at extremely low light levels, which is often critical for identification. For sites where colour detail matters, ColorVu provides a clear advantage.
- Hybrid light vs discrete IR-only or white-light-only units:Hybrid-light cameras let you balance visibility and discretion. IR-only cameras are covert but lack colour; white-light-only cameras may be intrusive. Hybrid designs provide the flexibility to use either or both depending on the scenario.
- Deep-learning analytics vs traditional motion detection:Traditional motion detection flags any pixel change and can produce nuisance alarms. Deep-learning person/vehicle classification produces more meaningful alerts, saving operator time and reducing alarm fatigue.
- 4 MP sensor vs 2 MP or 8 MP alternatives:4 MP strikes a practical balance: more detail than 2 MP for identification, but lower bandwidth and storage demand than some 8 MP systems. For many perimeter and parking applications, 4 MP at 25/30 fps offers the best trade-off of clarity and operational cost.
Customer testimonials and reviews
At the time of writing, there are no specific customer testimonials included with the product data. However, installers and end users evaluating similar ColorVu hybrid-light models typically report the following observations (representative, illustrative feedback):
