The Hikvision DS‑2CD2T66G2H‑2L is a powerful 6 MP bullet-style hybrid camera that combines ColorVu warm-light illumination with infrared (IR) night vision for reliable, full-colour surveillance 24/7. This model replaces the older DS‑2CD2T66G2, which only featured IR, and adds advanced hybrid lighting to switch automatically between visible light and IR based on ambient lighting conditions.
This “2L” version is designed with a shorter-range IR (up to 60 m) compared to the “4I” model (80 m), making it perfect for moderate distances, such as home driveways, retail exteriors, car parks, and warehouse entries.

Lens Options Explained
-
2.8 mm Lens:
Offers a wider field of view (~114° horizontal). Ideal for covering broad areas like courtyards, wide driveways, or large rooms where you need to capture more within the frame. -
4 mm Lens:
Offers a narrower, more focused view (~94° horizontal), providing better detail at longer distances. Ideal for monitoring entrances, corridors, or fences where subjects move through a narrower area.
Tip:
Use the 2.8 mm lens when width coverage is critical. Choose 4 mm if distance detail and narrower focus are more important.
Use Cases
-
Driveway & Perimeter Monitoring
The 2.8 mm variant captures wide driveways or front yards, while the 4 mm lens provides sharper detail at entry points or gates. -
Retail Exteriors & Loading Bays
Deploy the 2L model for colour video in low-light storefront areas or rear loading zones — perfect for theft deterrence and operational oversight. -
Home and Apartment Security
Suitable for wall- or soffit-mounted use around entry doors, garages, and common walkways. Choose black housing for discreet installs. -
Industrial and Warehouse Surveillance
The hybrid lighting ensures consistent, full-colour imaging in low-light indoor environments, and IR mode preserves visibility for larger bays after hours. -
Car Parks and Laneways
Excellent for moderate-length coverage with full-colour footage at night — supports better identification of people and vehicles compared to traditional IR-only cameras.
