Extra Info
AI by Camera
The DHI-NVR5232-16P-4KS2E is designed to record and manage AI metadata generated by compatible Dahua AI cameras. While the NVR itself does not perform onboard AI processing, it supports and stores intelligent data for powerful post-event review.
Key features supported through connected smart cameras include:
-
Facial recognition, with searchable metadata such as age, gender, mask, glasses, and beard detection
-
Automatic Number Plate Recognition (ANPR), with the ability to search license plates and apply allow/block list rules
-
SMD+ (Smart Motion Detection Plus), which filters motion events to focus on human and vehicle movement only
All of these AI events are searchable through the NVR interface, allowing operators to quickly filter and locate specific footage using descriptive attributes — such as a red vehicle, a person wearing a backpack, or a face with specific features.
Smart Search Capabilities
Once AI cameras are deployed, the NVR unlocks advanced metadata-based search tools. These tools enable users to conduct precise searches within recorded footage based on the following criteria:
-
Vehicle characteristics, such as type, color, or presence of a license plate
-
Human attributes, such as clothing color, accessories (e.g. backpacks, umbrellas), or facial features
-
Behavior-based triggers, such as loitering, tripwire crossings, or intrusion detection
This smart search functionality drastically reduces the time needed to investigate incidents or gather forensic evidence, making it especially valuable for high-security or high-traffic environments.
24MP Camera Support
The NVR supports camera inputs of up to 24 megapixels, enabling ultra-high-definition surveillance. This high resolution is ideal for applications that demand exceptional detail, such as:
-
Retail spaces, for identifying product interaction or theft
-
Corporate offices, for employee verification and visitor tracking
-
Public infrastructure, where wide-area clarity is essential for security and incident analysis
This capability ensures that even in large or crowded scenes, small details remain clear and usable during playback.
Fisheye Dewarping
The system includes built-in support for fisheye dewarping on one channel, allowing 360° panoramic camera footage to be corrected into usable viewing formats. Dewarped views can include:
- Panoramic perspectives
- Quad-view layouts
- Custom-defined regions of interest
Dewarping is available in both live view and playback modes, making it easier to monitor and review wide-area scenes, such as retail lobbies, warehouse floors, open office layouts, and parking structures.
DMSS Mobile App Integration
The NVR integrates fully with Dahua’s DMSS mobile app, offering remote access and system control via smartphone or tablet. Key app features include:
- Live view of all connected cameras
- Event playback and smart search on the go
-
Push notifications for AI-triggered alerts such as face detection, motion, or intrusion
-
Two-way audio support with compatible cameras, allowing users to communicate directly through the system
The DMSS app provides real-time access and control, making it an essential tool for users who need to monitor their system remotely or respond quickly to events.
Q&A
Q: Does this NVR perform AI detection itself?
A: No — all AI features like face recognition or ANPR are performed by the camera and sent to the NVR for storage and smart search.
Q: How many cameras can I connect directly via PoE?
A: Up to 16 cameras can be powered directly via built-in PoE ports (Ports 1–8 support ePoE and EoC).
Q: Can I record in full colour at night?
A: Yes, if you're using compatible full-colour cameras. This NVR supports recording whatever the camera provides.
Q: Does it work with third-party cameras?
A: Yes, it's ONVIF compatible (Profiles S, G, T), but AI features may not work with third-party cameras.
Q: Can I disable the camera lights or siren if I use TiOC models?
A: Yes, through the DMSS app or NVR interface, you can manage light and siren behavior.
Q: Will the siren or strobe trigger automatically?
A: If using TiOC cameras, yes — triggers can be set by event (e.g., SMD, intrusion).
Q: What’s the maximum recording resolution?
A: This model supports input and recording up to 24MP.
Q: Can I view and control this NVR remotely?
A: Yes, with the DMSS mobile app or via web browser.
