Based on a Large Multimodal Model (LLM), images and their corresponding natural language descriptions are mapped to a shared high-dimensional vector space. This enables versatile functionalities, such as open-ended text-to-image search, image-to-image search, and alarm triggering based on the presence of persons, vehicles, objects, events, or locations.

By understanding and correlating visual content and natural language, AcuSeek delivers human-like comprehension with machine-level precision and speed.
How Does AI Video Search Work in an NVR System?
AI video search helps an NVR identify and retrieve relevant footage based on detected objects, events or visual characteristics.
A typical AI video-search workflow involves five stages:
1. Video capture
Compatible IP cameras capture and encode the video before transmitting it to the NVR over the network.
2. Video analysis
AI algorithms in the camera, the NVR or both analyse the footage. Depending on the supported equipment, the system may distinguish people and vehicles, detect perimeter events or extract searchable visual attributes.
3. Metadata creation
The system associates detected targets and events with information such as camera location, date, time, object category and event type.
4. Search query
The operator selects an event filter, marks a target in recorded footage or enters a text or voice description, depending on the NVR’s supported search technology.
5. Ranked results and playback
The NVR searches the indexed video metadata and returns matching clips or snapshots, allowing the operator to review likely results instead of watching the complete recording.
Hikvision AcuSearch is designed to improve target-based retrieval and playback efficiency. Smart Search supports searches across recorded frames and events. On compatible VPro Series NVRs, AcuSeek allows users to search with natural-language text or voice descriptions for a specific object or scene.
Available search functions vary by NVR model, firmware, connected camera and system configuration.
FAQs
An AI NVR is a network video recorder that stores video from IP cameras and supports intelligent analytics or search functions. Depending on the system, it may classify people and vehicles, identify configured events, create searchable metadata and help operators retrieve relevant footage.
A compatible AI NVR can filter or retrieve footage using event types, target classifications, selected visual targets or natural-language descriptions. The available method depends on the NVR, camera, firmware and enabled analytics.
Retention time depends on available storage and recording settings. Higher image quality and continuous recording will use more space, while larger storage capacity can support longer retention.
In many cases, yes. However, compatibility should be checked to ensure stable video recording, smooth management, and access to key system functions.
The main considerations are channel count, storage capacity, camera compatibility, ease of deployment, and how quickly footage can be reviewed when needed. The right NVR should match both current requirements and future expansion.
Yes. An NVR can continue local recording without an internet connection if the cameras and recorder are properly connected on-site. Internet access is mainly needed for remote viewing and remote management.
Standard video search often requires manual review by time or camera. AI-assisted video search helps users locate relevant footage faster, reducing the time needed to review large amounts of video.
The number of channels should cover the cameras required today, while allowing room for future expansion. This helps ensure the system can grow with the site without early replacement.

Can an NVR Work Without the Internet?
Yes, an NVR can continue recording locally even if the internet connection is interrupted, provided the cameras and recorder are properly connected on-site. This is important for sites that cannot afford gaps in recording. Internet access is mainly needed for remote viewing, remote management, and certain cloud-based functions, not for basic local recording itself.
For businesses in Singapore looking for a system that balances daily usability with stronger search and management capabilities, Hikvision’s Network Video Recorders are designed to support a wide range of site sizes and operational needs. From straightforward recording to more advanced AI-assisted video search with AcuSeek, the right NVR can help teams move from simply storing footage to finding answers faster.
What to Look for When Choosing an NVR Camera System
Choosing the right NVR camera system starts with understanding how the site will be used day to day. A smaller office or shop may only need a few cameras and basic recording, while a larger site may need wider coverage, longer storage time, and faster ways to search video during an incident review.
