AI enhances CCTV systems in three main ways: 1) Reducing false alarms by distinguishing objects like people from surroundings using deep learning algorithms. 2) Improving image quality using techniques like WiseNRII that optimize noise and motion blur based on object detection. 3) Increasing storage efficiency through codecs like H.265 and Wise Stream that dynamically adjust compression based on motion detection and regions of interest, reducing bandwidth needs by up to 80%.

13. Reducing False alarm based on AI
The AI cameras detect and classify people, vehicles, faces and license plates and more in real time, greatly enhancing the accuracy
of video analytics. While conventional cameras detect motion based on its pixels and generate events even if users want to ignore.
AI algorithms can discern person as distinct objects separate from their surroundings such as waving trees, shadows, or animals.
AI cameras are able to help improve operator efficiency.

and motion blur depending movement of objects (person, vehicle). This effectively resolves the issue of image blur and ghosts effect caused by
excessive noise reduction.

51. Improved image quality
AI based Prefer Shutter technology utilizes the latest AI technology to identify appearance and movement of objects and readjusts the Prefer
Shutter value to an optimal level to effectively improve noise and reduce motion blur. In a scene without objects, shutters are automatically
adjusted to low speed to maintain low levels of noise as well as bright and clear images. In a scene with lots of object appearance and movements,
shutters are adjusted to high speed to reduce motion blur and deliver clear images.

H.265 was developed for high resolution
transmission with low bandwidth without losing
resolution or picture quality.
1992: JPEG
Mid 1990’s: MJPEG
1995: MPEG-2
2004: H.264
2013: H.265

58. Encoding H.26x (1/2)
58
Inter-Frame encoding: Compressing & transmitting only the changes between
subsequent frames.
Frame 1 Frame 2

59. Encoding H.26x (1/2)
59
Encoding the frames:
Divide the image to blocks that is 16X16 or 32X32 pixels (Macroblock MB).
Frame 1
Full frame
(I or Key Frame)
Frame 2
Partial Frame

64. H.265 + Wise Stream
Wise Stream is an efficient way to reduce storage and bandwidth by dynamically choosing your areas of
motion and regions of interest as your high definition areas, while leaving the rest of the video at a lower
resolution.

65. H.265 + Wise Stream with AI
• Save Bandwidth and Storage Costs
• Automatically Adjust Based on Motion in the Scene
• Works with H.265 and H.264

66. Improved Storage Saving
A new cutting edge video compression technology WiseStreamIII operates based on the object detection accomplished by AI algorithms. When
combined with the H.265 compression technology, bandwidth can be reduced by up to 80% without compromising the video quality, enabling
