Turret Camera Hikvision DS-2CD23123G2-LI2UY 12 MP, 2.8 mm, F2.8, Black

Hikvision DS-2CD23123G2-LI2UY 12 MP turret camera is a fixed-lens surveillance camera designed for indoor and outdoor monitoring. With a 12-megapixel sensor and a 2.8 mm fixed lens (F2.8), the camera provides high-resolution video suitable for detailed observation, identification and recording. The turret form factor and weather-resistant housing support installation on walls or ceilings and integration with PoE networks and standard NVR systems.

Advantages

The camera delivers very high image detail due to its 12 MP sensor, allowing clearer identification at typical monitoring distances. A 2.8 mm wide-angle lens covers broad scenes such as retail areas, office floors or building entrances without frequent repositioning. The F2.8 aperture balances depth of field and light sensitivity for general lighting conditions. The turret design simplifies aiming and installation while offering a compact, robust housing suitable for exterior placement when mounted under appropriate shelter.

Suitable for

• Retail spaces and shop floors for product and customer monitoring
• Office interiors and corridors for personnel and asset surveillance
• Building entrances, lobbies and reception areas
• Perimeter observation of smaller properties and parking areas
• Integration with PoE-enabled networks and standard NVR setups

When it may not be suitable

This fixed 2.8 mm lens provides a wide field of view but is not ideal when long-range, close-up identification is required; scenes that need detailed recognition at large distances may require a camera with a telephoto or varifocal lens. The F2.8 aperture is suitable for normal lighting but may not perform as well as lower-aperture optics in very low-light environments unless additional illumination is provided.

Key specifications

• Image sensor resolution: 12 megapixels
• Lens focal length: 2.8 mm (fixed)
• Aperture: F2.8
• Form factor: turret-style camera for wall or ceiling mounting
• Suitable for indoor and outdoor installations (weather-resistant housing)
• Networking: compatible with PoE power and common NVR systems

How to use

Install the turret camera on a stable wall or ceiling surface using compatible mounting hardware, aiming the 2.8 mm lens to cover the desired scene. Connect the camera to a PoE switch or injector for power and network access, or wire it into a compatible NVR network according to the installer’s guidelines. Configure resolution, frame rate and recording schedules via the NVR or camera web interface to balance image quality and storage use. Adjust angle and focus during commissioning to ensure optimal coverage and identification capability.

What to consider before purchase

• Required field of view: the fixed 2.8 mm lens gives a wide-angle perspective, not long-range zoom
• Lighting conditions at the installation site and need for supplementary illumination
• Compatibility with existing PoE switches, NVRs and network infrastructure
• Mounting location and weather exposure; ensure proper shelter or rated mounting for outdoor use

Usage recommendations

For best results, mount the camera at a height and angle that maximizes facial and object capture within the 2.8 mm field of view, use PoE for simplified power and data cabling, and combine with an NVR or cloud recording solution configured to retain footage at the desired resolution and retention period.
