Dahua XVR5232AN-4KL-I3/T 32-channel 4K DVR, H.265/H.264, Gigabit Ethernet, 16 TB support, Black

Dahua XVR5232AN-4KL-I3/T is a 32-channel digital video recorder designed for multi-camera surveillance that supports up to 3840×2160 (4K) resolution. The recorder accepts a mix of analog and IP inputs and uses Smart H.265+, H.265, H.264 and H.264+ compression to optimize storage and bandwidth. Network connectivity includes Fast and Gigabit Ethernet with standard protocols for remote access and integration. Local interfaces include one USB 3.2 Gen1 Type-A port, one USB 2.0 port and a single RJ-45 LAN port. The device supports a maximum single drive capacity of up to 16 TB and comes in a compact black housing suitable for commercial and residential installations.

Advantages

The XVR5232AN-4KL-I3/T combines multi-format video input compatibility with AI-assisted features to improve event detection and reduce false alarms. Smart compression modes and AI coding help lower storage requirements while preserving critical details. Gigabit Ethernet and common network protocols enable flexible remote monitoring and integration with existing IP infrastructure. Support for mixed analog and IP channels and Wi‑Fi camera access extends deployment options without replacing legacy cameras.

How to use

Install the recorder in a ventilated, dust-free location and connect cameras using the supported analog or IP interfaces. Insert a compatible 3.5" SATA hard drive up to 16 TB if local storage is required. Connect the unit to the network via the RJ-45 port and configure IP settings using DHCP or a static address. Use the web interface, client software or mobile app to add cameras, set recording schedules, enable AI detection features and configure event-triggered actions. Connect USB devices for data export or mouse control as needed. Apply a DC power source matching the device specification and confirm that firmware is up to date before commissioning.

Recommendations

For reliable long-term recording, use surveillance-grade SATA HDDs and configure regular overwrite policies. Adjust AI detection sensitivity and zones to reduce false positives in busy scenes. Ensure the network uplink supports the configured incoming bandwidth (up to 256 Mbps) when using many high-resolution IP channels, and enable Smart H.265+ to optimise storage and bandwidth use.
