IP camera Hikvision DS-2CD20166G3-IUY/SL (2.8mm) — 6 MP, outdoor, IR, PoE

The Hikvision IP camera DS-2CD20166G3-IUY/SL (2.8mm) is a 6 MP outdoor turret camera designed for reliable network video surveillance. Equipped with a 2.8 mm fixed lens and IR illumination, the camera delivers high-resolution images for perimeter, entrance and parking monitoring. The unit supports Power over Ethernet (PoE) to simplify power and data cabling and is built to withstand outdoor conditions while providing clear daytime and low-light performance.

Advantages

The camera combines a 6 MP sensor with a wide-angle 2.8 mm lens to capture detailed scenes with broad coverage. Integrated infrared LEDs enable monitoring in low-light or nighttime conditions without additional lighting. PoE support reduces installation complexity by carrying power and data over a single Ethernet cable. The turret form factor and weather-resistant construction make the device suitable for outdoor mounting while maintaining adjustable orientation for precise framing.

Suitable for

• Perimeter surveillance around buildings and facilities
• Entrances, gates and doorways monitoring
• Parking lots and outdoor vehicle areas
• Small to medium outdoor sites requiring high-resolution imaging

Key specifications

• Image resolution: 6 megapixels
• Lens: 2.8 mm fixed focal length for wide field of view
• Low-light capability: built-in infrared illumination for night vision
• Network interface: Ethernet with Power over Ethernet (PoE) support
• Form factor: turret-style outdoor camera with adjustable mounting angle
• Weather protection: designed for outdoor environmental conditions

How to use

Mount the camera at a stable outdoor location with a clear view of the monitored area, using appropriate screws and anchors for the surface type. Connect the camera to a PoE-capable network switch or injector to provide both power and data over a single Ethernet cable. Configure network settings and image parameters through the camera's web interface or compatible video management software to set resolution, IR behavior and motion detection zones. Aim the turret housing to frame the desired scene and secure the adjustable joints to maintain position.

Recommendations

For optimal image quality, position the camera to minimize direct sunlight and reflective surfaces in the field of view. Test IR coverage at night to ensure sufficient illumination for the required detection distance. Use a PoE switch with appropriate power budget and ensure the network has sufficient bandwidth for 6 MP video streams. Regularly check seals and mounting hardware to maintain weather resistance.
