Detailed Comparison Table
| Feature | DS-2CD3T87G3-LIS2UY/SL | DS-2CD2T87G3-LIS2UY/SL | Winner & Analysis |
|---|---|---|---|
| Image Sensor | 1/1.2″ Progressive Scan CMOS | 1/1.8″ Progressive Scan CMOS | DS-2CD3T87G3-L The larger 1/1.2″ sensor is superior. It captures significantly more light, resulting in better performance in extremely low-light conditions, less noise, and generally better dynamic range. |
| Lens | 2.8 mm | 2.8 mm | Tie Both have the same focal length, but the FOV is different due to the sensor size. |
| Field of View (FOV) | Horizontal: 110° Diagonal: 132° | Horizontal: 98° Diagonal: 118° | DS-2CD3T87G3-L This is a significant advantage. The 3087 model provides a much wider viewing area, allowing you to cover a larger scene with a single camera. |
| Dimensions (Ø×H) | 112.4 × 90.7 mm | ** 105 × 91.3 mm** | DS-2CD2T87G3-L The 2087 model is more compact and discreet if aesthetics and size are a concern. |
| Hybrid Light Source | ✅ Warm Supplemental Light (Always on, for full-color video) ✅ White Light Spotlight (Activates on alarm for deterrence) | ✅ Warm Supplemental Light (Always on, for full-color video) ✅ White Light Spotlight (Activates on alarm for deterrence) | Tie Both share the exact same advanced “ColorVu 2.0” hybrid lighting system for 24/7 color video and active deterrence. |
| Low-Light Performance | Min. Illumination: ~0.0005 Lux (with warm light on) | Min. Illumination: ~0.001 Lux (with warm light on) | DS-2CD3T87G3-L Both are exceptional, but the larger sensor gives the 3087 model a technical edge in the most challenging lighting conditions. |
| Common Features | ✅ 8MP (3840 × 2160) Resolution ✅ AcuSense (People/Vehicle analytics & filtering) ✅ Built-in Microphone & Speaker (2-way audio) ✅ IP67 Weather Resistance ✅ IK10 Vandal Resistance ✅ “S2UY/SL” Specific Features: Warm Light, White Light, Audio Alarm, Strobe Light Deterrence | ✅ 8MP (3840 × 2160) Resolution ✅ AcuSense (People/Vehicle analytics & filtering) ✅ Built-in Microphone & Speaker (2-way audio) ✅ IP67 Weather Resistance ✅ IK10 Vandal Resistance ✅ “S2UY/SL” Specific Features: Warm Light, White Light, Audio Alarm, Strobe Light Deterrence | Tie Both cameras are packed with the highest-end features Hikvision offers, including the full suite of audio and visual deterrents. |
Which Camera Should You Choose?
Choose the DS-2CD3T87G3-LIS2UY/SL (1/1.2″ Sensor) if:
Ultimate Image Quality is Critical: The larger sensor provides the best possible low-light performance and image clarity.
You Need a Wider View: The 110° horizontal FOV is ideal for covering large areas like parking lots, backyards, or open commercial spaces, reducing the number of cameras needed.
Budget is less of a concern, and you want the absolute best technology available in this class.
Choose the DS-2CD2T87G3-LIS2UY/SL (1/1.8″ Sensor) if:
You Want a More Discreet Design: The slightly smaller form factor is less obtrusive.
You are Monitoring a Standard-Sized Area: For a front door, driveway, or typical retail space, the 98° FOV is perfectly sufficient.
You want all the premium features (Hybrid Light, AcuSense, Deterrence) but may have a slightly tighter budget (the 2-series is typically more cost-effective).
Conclusion: Both are exceptional, feature-packed cameras. The choice boils down to:
Do you need the wider field of view and superior sensor performance? -> Choose the DS-2CD3T87G3-L (3-series).
Is a compact size and potential cost savings more important for a standard scene? -> Choose the DS-2CD2T87G3-L (2-series).
You cannot go wrong with either, but the 3-series model offers tangible performance benefits.
