High clarity surveillance videos are not only important legal evidences for post-incident investigations, with the aid of intelligent video analytics technology, they are also effective tools for crime prediction.
In 2018, WAMA starts off the new year with the release of two new 4K IP cameras. These cameras come with multiple features including 4K ultra-high resolution, H.265 compression technology, triple independent video streams, region of interest (ROI) smart encoding, automatic network replenishment (ANR) and built-in video analytic functions. The 4K vandal resistant compact dome camera and bullet camera are suitable for indoor or outdoor applications that require high clarity videos and intelligent functions.
“The security industry is moving very quickly with the emergence of many new technologies. 4K, H.265 and artificial intelligence are among the technologies that we anticipate will have a wide-spread use in the near future,” said Dr. Wallace Ma, CEO of WAMA Technology Ltd. “With the launch of the new NS8 series 4K IP cameras, we aim to bring security in the society to a higher level.”
The new cameras are capable of capturing videos at 3840 x 2160 pixels (8MP), which is four times the resolution of 1080p. The 4K imagery technology allows crystal-clear videos to be produced, ensuring all important details at the site of surveillance not to be missed.
H.265 video compression technology can reduce the network traffic and storage requirement by 50% in comparison to H.264. By optimizing the network bandwidth while maintaining the details of 4K resolution, the overall storage costs can be greatly minimized.
The cameras are also developed to simultaneously deliver 3 independent video streams to provide greater flexibility for users with different requirements:
3 independent video streams
Users can have the flexibility of choosing 2 streams with 4K resolution, or selecting different resolution for live viewing and video recording.
- Main stream with maximum 4K resolution at full frame rate
- Sub stream with maximum D1 resolution at full frame rate
- Third stream with maximum 4K resolution at 6fps
Region of interest
On top of the H.265 compression technology, the ‘region of interest’ encoding technology can further optimize network bandwidth and ultimately saves storage costs. A maximum of four regions can be pre-set as regions of focus, while redundant video data in areas that are not of importance will be omitted. This approach effectively compresses video data without the need of sacrificing image quality in the areas of interest.
Automatic network replenishment (ANR)
The ANR technology ensures safe recording of videos even during a network breakdown. When network failure is detected, videos will be automatically recorded onto the camera's micro SD card. When network is resumed, the videos will be stored back into the NVR.
Built-in video analytics
The 4K IP cameras also come with four built-in video analytic functions including tripwire detection, loitering detection, missing / unattended object detection and overcrowd monitoring. They are designed to intelligently analyze the captured videos at real-time. When abnormal events are detected, alarm notifications will be instantly sent to the operators, all without the need of human involvement.
