The cameras use Hikvision ColorVu technology, an F1.0 aperture, and sensitive imaging hardware to produce full-color video day and night. You receive more visual context when reviewing activity around entrances, vehicles, walkways, and other important areas.

Each camera records at up to 2560 × 1440 resolution, giving you more image detail than standard 1080p video. That additional detail can make it easier to understand what happened without relying on unclear, low-resolution footage.

The LUF camera model includes a built-in microphone and environmental noise filtering. Instead of seeing only part of an event, you can capture another layer of context that may help explain the situation.

The camera’s supplemental white light reaches up to 30 meters, helping it maintain colorful imaging when surrounding light is insufficient. This gives the camera a practical way to continue producing useful nighttime video even in zero-light conditions.

Bright entrances, windows, headlights, and shadowed areas can make ordinary footage difficult to interpret. The camera’s 120 dB WDR helps balance high-contrast scenes so both bright and dark areas remain more visible.

The DS-7732NI-M4 supports up to 32 IP cameras. You can begin with the cameras needed today and retain room to cover additional entrances, parking areas, buildings, or interior spaces later.

The recorder accepts camera resolutions up to 32MP, with support for as many as eight 32MP or 24MP inputs. This gives you the flexibility to add higher-resolution compatible cameras in locations where greater detail matters most.

HDMI 1 supports output up to 8K at 30 Hz, while HDMI 2 supports up to 4K at 60 Hz under supported configurations. This allows high-resolution footage and multi-camera layouts to be viewed on compatible displays with greater clarity.

The NVR can decode up to 32 channels of 2MP video at 30 fps, with additional configurations available for higher resolutions. You can review multiple cameras from one interface without reducing the system to a single-camera view.

Instead of searching through cameras individually, you can replay as many as 16 channels together. This makes it easier to follow movement across different areas and reconstruct the sequence of an event.

The recorder supports four SATA hard drives with capacities up to 16TB per drive. That provides the flexibility to configure substantial local recording storage based on your camera count, recording schedule, and desired retention period.

H.265+ compression can reduce required storage space by up to 75% under suitable conditions. This helps you use available hard-drive capacity more efficiently while preserving high-quality recorded video.

Hik-Connect support allows the properly configured system to be accessed remotely. You can check compatible live and recorded video without needing to remain in front of the recorder’s local monitor.

The cameras are rated IP67 for resistance to water and dust and can operate from -30°C to 60°C (-22°F to 140°F). This makes them suitable for many exposed indoor and outdoor surveillance locations.

Choose the 2.8 mm option for a wider 96.5° horizontal view or the 4 mm option for a narrower, more focused 75.8° view with longer DORI distances. The right lens helps match each camera to the area it actually needs to protect.

The NVR supports analytics supplied by compatible cameras, including functions such as line crossing, intrusion detection, ANPR, heat mapping, and people counting. This gives you a recorder that can accommodate more specialized cameras as your surveillance requirements evolve.

Supported POS information can be overlaid on live and recorded video, with transactions capable of triggering recordings and alarms. Retail operators can connect transaction activity with the corresponding camera footage for faster investigation.

Secure boot, signed firmware, HTTPS, AES-128 stream encryption, address filtering, access logs, and brute-force delay protection help defend the recorder and its video streams against unauthorized access.
