The Hikvision DS-2CD2343G2-LI2U 2.8mm Black is an IP surveillance camera that delivers 4MP resolution in a compact dome form factor. Equipped with a 2.8mm wide-angle lens, the unit captures clear, detailed images suitable for general-purpose monitoring. The camera supports infrared night vision, on-board motion detection and a weatherproof housing that enables both indoor and outdoor installation while maintaining a discreet black appearance.
Advantages
This camera provides a balance of image clarity and installation flexibility by combining 4MP resolution with a 2.8mm lens for wide field coverage. Built-in night vision extends monitoring capabilities after dark, and integrated motion detection reduces the need for constant manual monitoring. The weather-resistant enclosure supports outdoor placement and the compact black design helps the device blend into residential and commercial environments.
Suitable for
- General indoor surveillance in offices, retail spaces, and common areas
- Outdoor perimeter monitoring under sheltered and exposed conditions
- Monitoring entrances, driveways and parking areas where wide-angle coverage is required
- Integration into IP video systems for continuous or event-triggered recording
When it may not be suitable
The 2.8mm wide-angle lens prioritizes field of view over extreme optical zoom; it is not intended for long-range identification of distant details. Environments that require extremely high optical zoom, thermal imaging, or specialized audio recording will require different camera types or accessory equipment.
Key specifications
- Image sensor and resolution: 4MP (approximately 2688 x 1520) for detailed video
- Lens: 2.8mm fixed wide-angle lens for broad scene coverage
- Night vision: Infrared illumination for low-light and no-light conditions
- Network: IP camera for integration with network video recorders and VMS
- Housing: Weather-resistant design suitable for indoor and outdoor use
- Form factor: Compact dome-style camera with black finish
How to use
Install the camera at a height and angle that maximizes the area of interest while avoiding direct exposure to bright light sources that can cause glare. Connect the camera to your network via Ethernet (or PoE if supported) and add it to your network video recorder or management software following the manufacturer’s setup procedure. Configure motion detection zones and recording schedules to reduce unnecessary footage and ensure relevant events are captured. Regularly check lens cleanliness and firmware updates to maintain optimal performance.
What to consider before purchase
- Confirm network compatibility and whether Power over Ethernet (PoE) is available or required
- Assess required field of view and confirm 2.8mm focal length meets identification distance needs
- Ensure mounting location provides necessary protection from extreme weather if installed outdoors
- Verify integration requirements with existing NVRs, VMS or cloud services
Usage recommendations
For best results, position the camera to cover primary access points and use motion detection with event-triggered recording to conserve storage. If longer-range identification is needed, consider supplementing with a camera that offers optical zoom or a narrower-angle lens.
