Accurate, fast and simple video search

SMART Surveillance 2023 Surveillance, Products & Solutions

As the volume of video data grows exponentially, locating specific objects within the footage becomes increasingly challenging. To tackle this challenge, video analytics solutions have emerged as an indispensable tool, using metadata to accurately identify and track objects, thus becoming an essential component of surveillance systems. This is where Dahua Technology’s latest offering, AcuPick, becomes relevant.

How AcuPick works

Dahua’s AcuPick solution employs cutting-edge technology to analyse target features data via intelligent IPC and seamlessly transmits it to the back-end NVR. During the search process, the NVR extracts target feature values using its back-end intelligence capacity and compares them with those in the historical data from the IPC.

A crucial factor that makes AcuPick attractive is its deep-learning foundation that ensures high accuracy and fewer false positives or false negatives by designing rich data enhancement strategies, optimising neural network structure, and improving training strategies. False alarms are one of the biggest causes of resource wastage for many customers.

Benefits of AcuPick

Quicker search

Directly locate the target. Users can quickly and easily filter out vast amounts of useless information and locate the relevant video clips of their target.

Smart search by intrusion; users can draw an intrusion rule to search for video clips during SMD playback, helping then to quickly and easily identify the target that entered the area.

Easier operation

Just one click: AcuPick is easy to use. Users can search in preview or playback with just one click. With just one click, users can freeze the video and frame the target.

High accuracy

IPC/NVR extracts and models the target’s appearance details through an algorithm, mainly focusing on the appearance characteristics of the human body, such as clothing colour, clothing style, gender, body shape, and other relevant information.

It aims to determine whether the person/vehicle of interest appeared elsewhere at a distinct time captured by a different camera, or the same camera at a different moment in time.

Reduced TCO

Lower Purchase Price (no server needed). The IPC and NVR can effectively process data with intelligent computing power. They are suitable for small and medium-sized campus scenarios with fewer than 32 channels, without the need for a server.

Lower operation cost

AcuPick improves retrieval efficiency by providing easier operations, faster search functions, and higher accuracy. Furthermore, it is useful for various precise retrieval scenarios, reducing manpower and operational maintenance costs.

As video data continues to expand, AcuPick is well-positioned to become a vital tool for a wide range of industries, offering innovative and practical solutions to overcome the challenges of identifying objects in an increasingly complex digital landscape.
