The camera delivers a maximum resolution of 2688 × 1520, which is commonly referred to as 4 MP. This level of resolution provides noticeably more detail than standard 1080p, making it easier to identify faces, vehicles, and key activities. Higher resolution also allows for better digital zoom during playback without losing critical clarity. This is especially useful in entrances, retail spaces, and parking areas where identification matters.

Yes, this model includes AcuSense technology with deep learning–based human and vehicle classification. This allows the camera to distinguish people and vehicles from irrelevant motion such as animals, rain, or shadows. As a result, users experience fewer nuisance alerts and more reliable event notifications. This feature is particularly valuable in busy outdoor or semi-public environments.

The DS-2CD2743G2-LIZS2U uses Smart Hybrid Light technology that combines infrared (IR) and white light. It can automatically switch lighting modes depending on the scene and detection events. The supplemental light has an effective range of up to 40 meters, improving nighttime visibility. This flexibility helps capture clearer nighttime footage while avoiding overexposure or complete darkness.

The camera is equipped with a motorized varifocal lens ranging from 2.8 mm to 12 mm. This allows installers or administrators to remotely adjust the field of view after installation. Being able to fine-tune the angle and zoom saves time and reduces the need for physical repositioning. It also makes the camera more adaptable to different installation environments.

Yes, the camera includes a built-in arrayed dual-microphone for audio capture. It also supports multiple audio compression formats such as G.711, G.722.1, AAC-LC, and MP3. Audio adds an extra layer of situational awareness by providing context that video alone may not capture. This can be useful in entrances, customer interaction areas, or incident investigations.

The DS-2CD2743G2-LIZS2U is rated IP67 for weather resistance and IK10 for vandal resistance. This means it is protected against dust, rain, and physical impact. The camera is designed to operate in temperatures ranging from -30 °C to 60 °C. These ratings make it suitable for both indoor and outdoor security applications.

The camera supports H.265, H.264, H.265+, and H.264+ video compression. These formats help reduce bandwidth and storage requirements while maintaining image quality. H.265+ is especially beneficial for long-term recording and high-resolution video streams. This allows systems to store more footage without upgrading storage infrastructure.

Yes, the camera includes a built-in memory card slot supporting microSD, microSDHC, and microSDXC cards. It supports cards with capacities of up to 512 GB. This allows for edge recording directly on the camera if a network video recorder is unavailable. Local storage can also act as a backup in case of temporary network interruptions.

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 through a single Ethernet cable. This simplifies installation and reduces the need for additional power wiring. The maximum power consumption is approximately 12.5 W when using PoE.

The datasheet lists multiple compatible mounting accessories, including junction boxes, wall mounts, pendant mounts, and pole mounts. Examples include DS-1275ZJ-SUS, DS-1272ZJ-120, and DS-2200ZJ series mounts. These accessories allow the camera to be installed in a variety of environments and orientations. Accessories are listed as optional and are not stated as included with the camera.
