Wisenet7 camera devices provide clear and vivid images in resolutions of up to 4K suitable for forensic search applications. Hanwha Vision self-developed the F1.2 varifocal lens, the brightest among 4K lenses, are implemented to the 4K lineup.

The Wisenet7 SoC includes improved extreme WDR technology to reduce noise that occurs within the WDR imaging process. This provides us with clear and well contrasted images even with extreme backlighting conditions.

Wisenet7 camera technology uses different filters for motion and still areas within a camera’s field of view. This minimizes motion blur and improves edge and color definition of objects, making them easier to identify when viewing live video and during forensic review.

Wisenet7’s Lens Distortion Correction technology corrects video distortion created through the use of wide angle lenses, delivering video that more closely resembles what is seen through the human eye.

Generating high quality images in low light conditions is a fundamental and essential element of video surveillance camera, and noise reduction technology is especially important for network-based video surveillance camera in order to optimize transmission and storage efficiency. In extreme low light environment where the amount of light is insufficient, the level of noise remains the same while the components of image signals decrease, ultimately resulting in greater noise effects. High level of noise degrades the image discrimination power and increases the size of the data when compressing image, which causes reduction of transmission and storage efficiency.

Through SSNR (Smart Super Noise Reduction), Hanwha Vision’s unique low light image process technology, we are able to provide clear color images in dark environments with limited light by effectively reducing the noise and by minimizing the afterimage (motion blur) of objects. Through this, the size of image data is also significantly reduced allowing efficient storage and network transmission.

Video surveillance cameras have been developed to provide the best image quality under difficult and changing lighting environments. One of the most important aspects is the Wide Dynamic Range (WDR) or backlight correction technology, which reacts to the change of light. WDR is a technology for obtaining an excellent image by resolving the difference in brightness when the background is brighter than the main object or glare is generated by strong lighting.

Generally, WDR is required in the following situations:

• During daytime, where it is relatively dark inside a building and bright outside.
• A bright light shines towards the camera, such as with a car approaching the camera with its’ headlights turned on.

Hanwha Vision has been working continuously to strengthen its WDR function to provide optimized and vivid images in the strong backlit scenes. Hanwha Vision introduced the Wisenet7 implemented with the extreme WDR technology which can produce high resolution images suitable for forensic search application in the environment with strong backlit.

The WDR technology applied to Hanwha Vision cameras provide excellent image quality while minimizing side effects to deliver videos suitable for all applications.

The widespread adoption of high-quality video equipment is augmenting the video data size, highlighting the importance and necessity of data reduction. Efficient network streaming and data saving require ‘video compression’ that reduces data size while maintaining image quality of meaningful objects such as humans and vehicles.

Hanwha Vision WiseStreamⅢ is an AI-driven technology that effectively retains high video quality at low data size. The technology enables users to efficiently process more high-quality footage without installing additional network and storage devices.

In low light environments, if gain level is increased in order to raise sensitivity in low light environments, noise is amplified as much as signal is amplified. In extreme low light environment where the amount of light is insufficient, noise remains the same while the components of image signals decrease, resulting in greater noise effects. This noise degrades the image discrimination power and increases the size of the data when compressing image which causes reduction of transmission and storage efficiency.

Generating high quality images in low light conditions is a fundamental and essential element of video surveillance camera, and noise reduction technology is especially important for network based video surveillance camera in order to provide transmission and storage efficiency.

Hanwha Vision’s latest AI based low-light image processing technology offers efficient monitoring of detected objects in low-light environment. Also, it helps to capture the cutting-edge BestShots, one of the most important features required in AI camera. It greatly enhances the efficiency of videos by removing inevitable noises and minimizing objects’ motion blur based on analyzed AI data.

As AI becomes more broadly adopted across industries, it is likely to be more widely incorporated in video surveillance in the upcoming year. Edge-based AI (which filters and processes data locally on a camera) will be more ubiquitous, enabling end-to-end AI technology. Today, most security cameras send the data they collect to servers to be analyzed. However, with edge-based AI, the data is analyzed by the camera first, and subsequently sent to the server. This reduces the burden of transferring and storing large amounts of data to a server, thereby increasing efficiency, saving time, and reducing server costs typically required to analyze data.

• Increase event monitoring accuracy by reducing false alarm
  
• Classify Target Objects with attributes
  
• WiseDetector to specifically detect user-interested objects
• Disease prevention solutions by using AI technology
  
• BestShots for minimizing storage and bandwidth requirements
  
• AI search when used with non-AI cameras
  
• AI NVR supports LPR (License Plate Recognition) search
  
• Wisenet SSM, the best partner for AI smart search
  

WiseDetector detects user-interested objects with P AI cameras. Once the training is done and the data is sent to the cameras, WiseDetector will function as one of the regular detection on the WiseAI application.

P series AI cameras can prevent the spread of disease through multiple AI functions. Wisenet occupancy monitoring application enables P series AI cameras with people counting function which prevents people to be over-crowded. In addition, the attribute classification function enables face mask detection through P series AI cameras in order to send alerts. Finally, P series AI cameras detects each individual and therefore sends out alerts if the proximity gets higher than pre-set distance.

Solution

Once hackers plant malicious codes in firmware, sensitive information (certifications, encryption key, encryption processing, video information, etc) can be leaked.

Wisenet7 chipsets contain Hanwha Vision’s own embedded security platform module, HTPM (Hanwha Trusted Platform Module). Critical information is saved in the Secure Storage of chipsets and processed through the Secure OS.

Additionally, the Secure Boot feature verifies firmware during each step of the device boot, blocking the execution of malicious firmware once infected.

Solution

To achieve safe communication between interconnected security devices, one must use encryption to protect communication and all Devices should be cross-verified and authenticated.

Without mutual authentication, hackers can employ the ‘Man in the Middle’ attack to eavesdrop or tamper with the data during encrypted communication.

Hanwha Vision supports mutual authentication of interconnected devices to prevent hacking during encrypted communication, securing sensitive information from leakage or damage. In 2018, it introduced its own ‘Root CA,’ inserting device authentication to each product in the manufacturing stage. Even if one camera is hacked due to security vulnerabilities, the entire system can still be protected as the authentication is all different for each device.

Mutual authentication between devices enables secure communication, while authentication per device can defend the system against large-scale hacking.

Solution

Video footage captured by all cameras is encrypted during the entire process of data transfer, storage and backup.

Without encryption, personal video can be leaked or altered by others regardless of the user’s intention.

Hanwha Vision supports data encryption during video transfer or data storage on camera SD memory cards as well as ZIP encryption for data backup on PCs or other storage devices.

Solution

Devices compromised by malicious software can give a hacker the ability to run system actions, this will be true for compromised Open Platform apps too.

Wisenet7 security verification checks for data integrity at boot up or after updates.

An electronic signature is employed to secure open platform apps. Each app vendor is supplied with their own key to perform verification every time an app is installed.

These measures can ensure the integrity of Open Platform apps and completely block malicious firmware or apps from operating.

Malicious software will be rendered inoperable by the electronic signature which prevents compromised firmware or apps from running.
