New from Hanwha Techwin are five Wisenet P ultra-high definition 4K AI cameras. From the Hanwha Techwin Premium range, they come with deep learning video analytics.
The license-free deep learning video analytics simultaneously detects and classifies various object types, including people, vehicles, faces and license plates. Supporting the analytics are Wisenet AI algorithms unique to Hanwha Techwin, able to identify the attributes of objects or people, such as their age group, their gender or the colour of the clothing a person is wearing.
The attributes are saved as metadata alongside the images captured by the new cameras, enabling users to search for specific objects or incidents. The algorithms are even able to recognise if a person is wearing glasses or is holding a bag, the product developers add.
The AI cameras have a BestShot feature which, as its name suggests, is able to select the best images which have been captured of a person or object, and only send these together with the associated metadata, to a storage server. You can use VMS (video management software) from developers such as Genetec and Milestone Systems, as well as Wisenet WAVE and Wisenet SSM, to forensically search for specific objects or people, by filtering the recorded metadata.
The analytics can be configured to ignore video noise, waving trees, moving clouds and animals, all of which might normally be the cause of false alarms when standard motion detection or sensors are being used to detect activity. This ability to minimise time wasting and costly false alarms means control room operators and security personnel are able to focus on responding to real incidents and emergencies, Hanwha adds.
At some point, when the number of people being tested positive for COVID-19 begins to reduce, thought will no doubt be given as to how businesses will be able to safely re-open. Inevitably, social distancing rules will have to remain in place, and this is likely to mean only a specified number of people will be allowed to be in a controlled area at any time, the firm says.
With this in mind, the Wisenet AI algorithms built into the new Wisenet P 4K AI cameras can be used to count the number of people entering and leaving a premises. The data can be displayed to provide managers with information on the number of people present.
For the retail sector the cameras have been integrated with Wisenet Retail Insight (v2.0), which enables retailers to gain a greater understanding of customer behaviour and buying patterns.
The Wisenet Retail Insight business intelligence solution uses people counting, heat mapping and queue management applications to display statistical analytics on a centralised dashboard, with other practical information such as weather reports. With the help of Wisenet AI algorithms, Retail Insight is also able to display the age and gender of store visitors, allowing retailers to granularly analyse customer demographics.
Other features:
•Digital auto-tracking: The cameras are able to transmit two streams of video, providing the option for operators to see a camera’s full field of view, whilst 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.
•Wide Dynamic Range (WDR) which performs at up to 120dB to produce clear images from scenes containing a challenging mix of bright and dark areas which normally results in overexposed or underexposed images.
•DC output: A 12V DC power supply with maximum 50mA provides sufficient power to support external devices, including LEDs, PIR sensors and glass break detectors, eliminating the need to install separate power supplies for each of them.
•Alarm in/out ports: Connected devices such as LEDs can be activated when a camera detects and classifies an object or person.
• 2 SD card slots allow video or data to be stored at the edge should there be disruption to the network. Video evidence, which might have been potentially lost, can be retrieved when the network connection has been restored.
The five Wisenet cameras are:
– PNB-A9001 – 4K AI box camera
– PNO-A9081R – 4K AI bullet camera
– PNV-A9081R – 4K AI vandal-resistant dome camera with built-in IR illumination
– PND-A9081RF – 4K AI flush-mount dome camera with built-in IR illumination; and
– PND-A9081RV – 4K AI dome camera with built-in IR illumination.
With the exception of the Wisenet PNB-A9001, all models come supplied with a 4.5~10mm (2.2x) motorised varifocal lens which facilitates auto-tracking and allows operators to zoom into a camera’s field of view to see close up detail of any activity and functionality.
The dome cameras have a four-part magnetic modular design which makes them extremely easy to install. The ability to prefigure IP network settings without the need to remove the camera modules from their packaging, also reduces the time an engineer has to spend on site and/or cause disruption.
Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe said: “We are proud of all the new innovative products and solutions we have launched over recent months, but this new camera range is a particularly good example of how Hanwha Techwin is continuing its 30 year journey of innovation and adding real value to video surveillance solutions.
“By harnessing the power of Deep Learning AI, we are providing security personnel with an extremely powerful and accurate tool to help them keep one step ahead of intruders and we are also able to provide businesses with information which could help them be more productive.”
