Hanwha Vision has announced that it is expanding its range of AI cameras with new four and five-channel multi-directional cameras, powered by an AI engine, that provide operators with a 360° view and video analytics.

According to the company, the solutions rapidly classify and detect people, faces, vehicles (including vehicle types) and licence plates, as well as providing AI-based loitering and line crossing detection, Auto Prefer Shutter control, WiseStreamⅢ smart compression technology and WiseNRⅡnoise reduction.

The benefits of AI

Hanwha Vision highlights that AI cameras help minimise false alarms; deep learning AI video analytics ignore video noise, waving trees, moving clouds and animals, all of which may trigger false alarms when standard motion detection technology or sensors are being used to detect activity.

This higher level of performance means control room operators and security personnel can focus on responding to real incidents and not waste time and effort on false alarms.

Object classification also allows for more efficient forensic search, meaning security managers can quickly find relevant event footage for further investigation.

Virtual areas can be set up with AI object detection so that if a person is identified as loitering in a specific area, an alert is sent to the operator to take action.

Enhanced image quality

Hanwha Vision also says that AI is helping to improve the footage quality for operators, with the BestShot AI feature automatically choosing the best images of an object or event to send to a backend server, minimising storage and bandwidth requirements.

The company’s AI compression technology, WiseStreamIII, can also apply low compression rates to objects and people detected in footage and high compression to the remaining field of view.

This improves bandwidth efficiency without compromising the quality of the footage that operators view.

Hanwha Vision emphasises that solutions like the WiseNR II noise reduction uses AI to reduce blur in noisy, low-light environments.

The solution is further complemented by AI-based Prefer Shutter technology that automatically adjusts shutter speed to further reduce motion blur.

Multi-directional cameras

The multi-directional cameras require significantly less cabling and infrastructure, compared with what would normally be required to enable up to five separate cameras to cover large and complex scenes.

Meanwhile the AI on the camera (edge AI) needs less server room space as analytics is carried out on the device and only metadata is transmitted.

Once the camera is installed, the PTRZ remote adjustment feature on the PNM-C34404RQPZ model also allows users to adjust the camera settings, lens position and viewing angle through a web viewer, making them multi-directional cameras.

Operators no longer have to be physically present at the camera installation site for every tweak and minor adjustment, delivering unparalleled operational efficiency.
