Product Overview

This network video recorder receives video through your local network and stores footage on installed surveillance HDDs. Its 32-camera capacity allows a site to expand as coverage needs grow. Cameras connect through external network switches, making the recorder suitable for buildings where cameras are distributed across several floors or zones.

Key Features and Benefits

High-Resolution Recording with Clear Bandwidth Limits

Support for 16MP cameras lets you combine detailed entrance views with lower-resolution indoor coverage. Incoming, recording and outgoing bandwidth each reach 256Mbps with AI disabled, falling to 180Mbps when AI is enabled. Add up camera bitrates before choosing recording settings and leave capacity for changing scene activity.

WizSense AI for More Relevant Events

Recorder processing supports one channel of face detection and recognition, two channels of perimeter protection, or four channels of SMD Plus, subject to the supported AI configuration. Human and vehicle filtering helps reduce distracting motion alerts. Face management supports up to ten databases containing 20,000 images in total.

Additional Analytics from Compatible Cameras

Supported AI cameras can provide functions such as ANPR, people counting and heat maps. These capabilities depend on the connected camera and firmware. Discuss which events matter to your team before selecting cameras for a complete CCTV surveillance solution.

4K Monitoring and Practical Playback

HDMI supports a 3840 × 2160 display, while VGA supports Full HD. With AI disabled, decoding reaches 16 streams at 1080p or four at 8MP, at 30fps. Camera recording capacity and simultaneous full-resolution display capacity are different limits. Event playback helps operators locate relevant footage.

Two HDD Bays and Efficient Compression

This 2HDD NVR supports up to 20TB per compatible drive, with capacity subject to operating conditions. Smart H.265+ helps reduce storage demand with compatible streams. Retention depends on camera count, bitrate, recording schedule and usable disk space; choose HDD capacity around the number of days you need.

Remote Viewing and System Integration

Gigabit Ethernet supports network connectivity, while supported mobile and browser access lets authorised users check footage remotely. ONVIF helps integrate compatible third-party cameras. Four alarm inputs, two alarm outputs and RCA audio connections provide options for linking recording with other site equipment.

Recommended Applications

• Garment factories and warehouses monitoring loading areas and stock movement
• Corporate offices covering entrances, corridors and shared spaces
• Retail stores and supermarkets reviewing customer-facing areas
• Schools, clinics and apartment buildings managing multiple camera zones

Technical Specifications

Compatibility and Verification Note

Confirm HDD inclusion, approved drive models, camera compatibility and supported combinations of AI functions before ordering. Cameras require an external PoE switch or separate power. Third-party video compatibility does not guarantee access to every Dahua-specific analytic feature.

Why Choose This Dahua WizSense NVR?

Choose this model when you need room for 32 cameras, two-drive storage and recorder-based analytics in one unit. Compare the wider Dahua NVR range against your camera count, event requirements and recording retention target.

Frequently Asked Questions

How many cameras can it record?

Up to 32 IP cameras, provided their combined streams remain within the recorder's bandwidth limits.

Does this NVR have built-in PoE?

No. Use an external PoE switch or supply power separately to each camera.

Can it record without internet?

Yes. Local recording works with a functioning camera network and installed HDD. Off-site viewing requires internet connectivity.

Does enabling AI affect performance?

Yes. Bandwidth and decoding capacity decrease when AI processing is enabled.

Will it work with other camera brands?

Compatible ONVIF cameras can connect, but advanced analytics and configuration features need verification.

Does two-drive storage mean automatic backup?

Two drive bays describe storage capacity, not a guaranteed backup arrangement. Export important recordings separately.

Can every camera use recorder-based face recognition?

No. Full face detection and recognition on the recorder supports one video channel; camera-assisted modes have separate limits.
