• ACTi real camera demo
• High megapixel - Wide FOV
Panorama/Cylindrical Application
CylindricalFOV: 170Deg
Video is digitally wrapped (flattened) on edges due to curvature effect from lens
• Megapixel with zoom
Better clarity and detail when zooming in on objects

• Video cropping with independent streaming
Video cropping is used for indoor application – shopping store => 1 camera replacing 4 camerasFor scenery that is close, it is effective. For scenery that is far, the object appears to be smaller and hence not so effective under cropping
• Electronic PTZ
Beneficial with Wide FOV/High megapixel cameras:1.Do digital pan, tilt, zoom without moving mechanical parts
2. Wide FOV + ePTZ => A large field of view is constantly present, but for example when MD in one regions happens the view can auto ePTZ to the MD region, while the other camera view is still being monitored and recorded
FAQ
• Why is optical zoom only available up to 3MP?
Ans: 3 A’s are the key to good video: Auto white balance, Auto focus & Auto exposure. All three A’s require frame to frame comparison for video algorithm to take place. Having 30fps for video image processing is a key factor.
When >3MP, the frame rate is reduced and therefore the amount of data required for video processing will not be enough, or time taken will be too long to achieve a good picture that meets the 3 A’s.
For higher megapixel cameras beyond 3MP, the pixel count is high enough so digital zoom is considered instead.
ACTi is not chasing a multi megapixel resolution only, rather ACTi is focusing to adopt full camera technologies in addition to just higher resolution.
FAQ
• Why is Day & Night only available up to 3MP?Ans: Under such a large picture, the ability to do D&N correctly is a challenge. Focus shift, noise levels at night mode vary within the larger picture. Another reason is because peripheral components such as lens, IR cut filter etc will need to be able to support >3MP resolutions as well, and there is a technical barrier. Of course if these barriers at the peripheral components can be resolved, then ACTi will adopt D&N into >3MP cameras.
• Why is WDR/DNR only available up to 2MP?Ans: The main reason is because the video data beyond 2MP is too much for the ISP processing engine to handle calculations intended for WDR & DNR. Another reason is the reduced frame rates at >2MP means that the frame to frame comparison is not highly efficient.
• Why is ePTZ only available at 5/10MP?Ans: This is because the FOV is wide enough to allow significant space/movement for ePTZ.
• Why is video cropping with 4 streams only available at 5/10MP?Ans: This is because the overall picture size is large enough to allow significant use of video cropping at 4 different regions within this picture. If the picture size is small, then transmitting the entire picture rather than 4 separate pictures makes more sense.

DSP AVERAGE EXCELLENT FAIR
SoC EXCELLENT FAIR EXCELLENT
•SoC (System on Chip) has dedicated performance for IP camera applications - ACTi adoption - To achieve multi megapixel, the algorithms are highly complicated so a dedicated processor with full computing power is necessary
•DSP (Digital signal processor) are based for multi purpose applications, not necessarily for IP surveillance - H.264 baseline profile at most
•Key performance differentiators:-Maintaining good video quality under compression-Able to achieve high frame rates at high megapixel resolution-Network streaming with low latency and jitter-Overall firmware stability in varied working environments

•The camera ISP is in charge of video processing, while Codec for video compression - They are doing completely different functions, putting them into one chip may limit overall performance and stability
•Each technology to be developed separately - Separate development will allow greater technology improvement in their specific fields - ACTi is following a separate development trend until both technologies are mature
FAQ
• Why type of H.264 compression is ACTi using and why?Ans: ACTi is adopting baseline for initial product phase with VGA ~ 2.0MP, and will move to high profile (skip main profile) for second phase from 2.0MP ~ 10.0MP. High profile includes more intelligent encoding with added features, so it means that less information decoding (as compared to baseline) is required by the NVR system, hence less CPU resources are required by the NVR server.
• Can ACTi achieve multiple streaming?Ans: Yes, dual streaming can be achieved at all video resolutions. For example, it can be two H.264 streams, or one H.264 stream + one MJPEG stream.At 5/10MP cameras, up to 4 independent video streams can be outputted from 4 different regions within the picture.
