This camera delivers a maximum resolution of 4 megapixels, specifically 2688 × 1520. This level of detail allows for clearer identification of people, objects, and vehicles compared to standard 1080p cameras. The higher resolution is especially useful when reviewing footage for evidence or zooming in digitally. It strikes a balance between image clarity and efficient storage use when paired with modern compression.

Yes, the DS-2CD2143G2-LI(S)(2U) features Acusense technology with human and vehicle classification. This allows the camera to filter out motion caused by things like rain, shadows, or animals. By focusing alerts on people and vehicles, it reduces false alarms and saves time during incident review. This makes it more practical for real-world security monitoring.

The camera includes both infrared (IR) and white light illumination, known as Smart Hybrid Light. Depending on the scene and configuration, it can use IR for discreet monitoring or white light for full-color night images. The illumination range extends up to 30 meters. This flexibility helps improve nighttime visibility and evidence quality.

Yes, the -2U variant includes a built-in arrayed dual-microphone. It supports multiple audio compression formats and includes environmental noise filtering. This allows the camera to capture clearer audio alongside video when enabled and permitted by local regulations. Audio can add valuable context during incident review.

The camera is rated IP67 for dust and water resistance, making it suitable for outdoor and indoor installations. It is also IK10-rated for vandal resistance, which helps protect it from physical impact. These ratings make it well-suited for exposed or high-traffic areas. However, it does not include a specific anti-corrosion coating.

The DS-2CD2143G2-LI(S)(2U) supports H.265+, H.265, H.264+, and H.264 video compression. These options allow you to optimize for either maximum compatibility or reduced bandwidth and storage usage. H.265+ is particularly useful for long-term recording as it significantly lowers file sizes. This helps reduce storage costs without sacrificing image quality.

Yes, the camera includes a built-in microSD card slot. It supports microSD, microSDHC, and microSDXC cards with capacities of up to 512 GB. Local storage is useful as a backup if the network connection is interrupted. It can also be used for standalone recording in smaller installations.

The camera can be powered using 12 VDC or Power over Ethernet (PoE) compliant with IEEE 802.3af. PoE allows both power and data to be delivered over a single Ethernet cable. This simplifies installation and reduces wiring requirements. Maximum power consumption is under 8.5 watts when using PoE.

Yes, it features true Wide Dynamic Range (WDR) rated at 120 dB. This helps balance scenes with both very bright and very dark areas, such as entrances with strong backlighting. WDR improves visibility of faces and details that might otherwise be lost. It is especially helpful in locations with variable lighting throughout the day.

The camera is available with fixed focal lenses of either 2.8 mm or 4 mm. The 2.8 mm lens provides a wider field of view, while the 4 mm lens offers a narrower view with more detail at distance. This allows installers to choose the lens that best matches the coverage requirements. Both options use a fixed aperture of F1.6 for good low-light performance.
