Câmara de vigilância IP Hikvision DS-2CD1343G2-LIU dome 4 MP, 2,8 mm, 2560×1440, IR 30 m, PoE, IP67

The Hikvision DS-2CD1343G2-LIU(2.8mm) Dome is a 4 MP IP security camera designed for indoor and outdoor fixed surveillance. The camera has a metal turret housing with IP67 protection, supports ceiling or wall mounting, and includes a built-in microphone. It provides day/night operation, 2560 x 1440 resolution, IR night vision up to 30 m and wired Ethernet connectivity with PoE support.

Advantages

This model offers wide-angle coverage with a 2.8 mm fixed lens and a diagonal field of view of 114°, 360° rotation capability and pan/tilt control for flexible installation angles. Image quality is enhanced by WDR, 3D noise reduction and H.264+ compression for efficient streaming and storage. The camera supports remote management via web interface and the Hik-Connect app and includes security features such as password protection, digital watermarking, motion detection and privacy masking.

How to use

Mount the camera on a suitable ceiling or wall surface using the included mounting points and ensure cabling for power and network is routed according to local standards. For PoE installations connect a compatible IEEE 802.3af switch or injector; alternatively provide 12 V DC and up to 0.4 A on the DC output. Configure the device through its web interface or the Hik-Connect mobile app, set desired resolution, frame rate and enable motion detection, privacy masking or ROI encoding as needed. Position the camera angle using pan and tilt controls to cover the required scene and verify night vision performance in low-light conditions.

Recommendations

Use shielded outdoor-rated Ethernet cable for PoE installations and ensure the mounting position provides unobstructed view and protection from direct weather exposure where possible. Regularly update firmware and secure access credentials; enable digital watermarking and motion detection to improve evidential integrity and reduce false alerts.
