2-megapixel AI cameras

Hanwha Techwin has added five 2-megapixel high-definition AI cameras to its Wisenet P series. The new cameras are designed to complement the 4K models that the manufacturer launched in 2020.

As with the 4K models, the new cameras come with Deep Learning AI video analytics which delivers detection accuracy, while minimising false alarms, the developers say. It does so by simultaneously detecting and classifying various object types, such as people, vehicles, faces and car number plates.

The AI video analytics is supported by Wisenet AI algorithms which identify the attributes of objects or people, such as their age group and gender or the colour of clothes. The attributes are saved as metadata alongside the images from the Wisenet P series AI cameras. A users can search for specific objects or incidents. The algorithms are even able to recognise if a person is wearing glasses or is holding a bag.

Operators can use VMS (video management software) from developers such as Genetec and Milestone Systems, as well as Hanwha Techwin’s Wisenet WAVE and Wisenet SSM, to forensically search for specific objects or people by filtering the recorded metadata, as well as use the search features of the latest Wisenet X network recorders (NVRs) which are able to read AI metadata from the cameras.

A recent firmware update, incorporated into the 2-megapixel cameras and available as a downloadable upgrade for the 4K models, sees face mask detection and social distancing analytics added. There is also enhanced people counting and queue management functionality. To help remove the risk of overcrowding and to assist, for example, store managers make best use of staffing, this includes the ability to count the number of people queuing and generate alerts if a set maximum number is passed.

The cameras also come with Hanwha Techwin’s Occupancy Monitoring application which generates alarm outputs that can be used to control automatic doors or a traffic beacon, as well as trigger the display of ‘wait’ or ‘enter’ messages when the maximum permitted number of people allowed in an area at one time, has been reached. With these various licence-free Deep Learning AI video analytics applications available as standard on the Wisenet P series AI cameras, users do not have to incur the cost of purchasing licences to be allowed to use them.

Features of the new 2-megapixel Wisenet P cameras include:

– Digital auto-tracking which enables the cameras to transmit two streams of video, providing the option for operators to see a camera’s full field of view, while at the same time using a digital PTZ auto-tracking feature while viewing Full HD images, to track the movements of a person or vehicle.
– WiseNRII optimises image noise reduction to reduce blurring.
– 50ma output which can be used to power LEDs, sensors or glass break detectors.

The new cameras come with WiseStream III complementary compression. This applies a low compression rate to objects and people which are detected and tracked by AI, while applying high compression to the remaining field of view. When combined with H.265, this results in an improvement in bandwidth efficiency by up to 80 per cent the makers claim compared to H.264.

To further minimise network bandwidth and data storage, the cameras have a BestShot feature which selects the best images which have been captured of a person or object and only send these, with the associated metadata, to a storage server.

The new cameras are:

– PNB-A6001 box camera
– PNO-A6081R bullet camera with built-in IR illumination
– PND-6081RV dome camera with built-in IR illumination
– PND-6081RF flush mounted dome camera with built-in IR illumination
– PNV-A6081R vandal-resistant dome with built-in IR illumination

Uri Guterman, Head of Product and Marketing for Hanwha Techwin Europe, said: “We are confident that these new affordable cameras will help prove that AI based video surveillance technology is not just suitable for high-end, mission critical applications. In addition to helping combat criminal activity, we believe there are countless applications where the business intelligence captured with the assistance of the Deep Learning AI video analytics, as well as the cameras’ ability to help businesses operate safely during the COVID-19 affected era, will ensure they offer a high return on investment, regardless of where they may be deployed.”
