Video Mode (NC450 only)
You can select between Area of Interest, Turbo Picture, and Motion Adaptive mode.
•
Area of interest - This mode generates displayed image by directly cropping the native 2-megapixel image
captured by the image sensor. It provides the greatest details for the region you're most interested to
see in the scene, but limits max. frame rate to 15. Once this mode is selected, a preview window will be
displayed at the bottom of this page. Click and drag on the preview window and press [Save] to set the
area of interest.
• Turbo Picture
- This mode will provide you with the best video quality, but max. frame rate will be limited
to 15.
• Motion Adaptive
- This mode will provide up to 30 FPS at maximum 640 by 480 resolution.
Stream Setting
You can change the setting of resolution, codec, frame rate, and quality for the video stream. If you need to
watch the live video on your mobile phone or PDA, please check the [Enable 2nd stream (include 3GPP)] box
to enable the Stream-2 video, and the stream setting of the secondary stream will be displayed. Check [3GPP
Mode] box to enable the viewing of secondary stream on a 3GPP-capable cell phone.
Intelligent Frame rate
Enabling this option allows the camera to automatically lower current video frame rate when the camera
detects little or no motion in the scene. And when the camera detects motion in the scene, it will then bring
the frame rate back to normal user-defined level again to smoothly record every important moment, thus
avoiding wasting precious bandwidth and storage space on transmitting and recording video streams when
there's really nothing significant to record in the scene.
Active Bandwidth Management
When network congestion occurs, Compro network camera can intelligently force down current user-defined
video bit rate and bring it back when healthy bandwidth level becomes available. This avoids video quality
deterioration and frame dropping by restricting the camera from sending excessive amount of data while the
network is already overloaded. To activate the function, select [Enable] from the drop-down list.
