Camera settings

    Image Settings Use this option to configure the image quality and other settings (such as Timestamp Location) used for the selected camera during alarm and surveillance activities. Element Description Brightness (0-255) Sets the brightness of the captured image. The value can be set from 0 to 255. Gamma Correction Use this control to adjust the overall brightness of the camera image. Gamma Correction enables you to display captured image more accurately on your computer screen. Images which are not properly corrected can look bleached out or too dark. Rotate Camera Image 180 Degrees Select to rotate the image captured by the camera 180 degrees. This is useful for correctly orienting the image captures included in alert notifications and in the NetBotz Advanced View when the device has been mounted upside down due to installation location restrictions. Note This option is not available for use when configuring Capture Settings for CCTV Adapter Pods. Type of Lighting Use this control to specify the color balance settings that will be used by the camera. The four pre-configured color balance selections are: Fluorescent: best color balance settings for locations with fluorescent lighting. Incandescent: best color balance settings for locations with incandescent lighting. Daylight: best color balance settings for locations with natural lighting. Auto-detect: analyzes the current lighting conditions and automatically selects the best. Custom: use the Red balance and Blue balance controls to fine tune the image to your specifications. Red Balance (1 - 254) Adjusts the color balance of the image to counteract the effect of the lighting in the clip. Blue Balance (1 - 254) Adjusts the color balance of the image to counteract the effect of the lighting in the clip. Timestamp Location Use this control to specify the location of the timestamp within the image capture: None, Bottom right, Bottom center, Bottom left, Top right, Top center, and Top left.  

    Define when the selected camera will begin to capture data during an alarm, as well as the quality of the clip generated by the camera for alarms. Note The Alarm Capture Data settings have nothing to do with how clips are generated for normal surveillance activities. For information about the settings that affect surveillance clips, see Surveillance Settings options under Surveillance feature. Element Description Camera Resolution Sets the resolution of the images captured by the camera. The available sizes depend on the capabilities of the selected camera. Larger image resolutions will require increased amounts of disk space. Maximum Rate Sets the maximum number of frames per second recorded to the disk when a clip is captured. This setting defaults to 1 frame per second. Image Quality Specifies the amount of compression that will be applied to captured images. As compression is increased, file sizes decrease but the quality of the image decreases as well. The available values, from highest image quality/largest file size to lowest image quality/ smallest file size are: High Quality, Normal Quality, Normal Compression and High Compression. Note Actual frame rate available from image processor depends on the resolution and image quality of generated images. A maximum frame rate of 30 frames per second is available only at Normal Quality or lower and only at resolutions up to 640x480. The maximum frame rate for 800x600, 1024x768, and 1280x1024 (if available) at Normal Quality or lower is 10 frames per second. For example, if you configure a Camera Pod 120 to capture images in High Quality, the Maximum Rate for some resolutions changes: At 640x480 and lower resolution the maximum frame rate drops from 30 frames per second to 20 frames per second. In 800x600 the maximum frame rate is unchanged (stays at 10 frames per second). In 1024x768 and 1280x1024 the maximum frame rate drops from 10 frames per second to 8 frames per second. Post Alert Capture Time (seconds) Specifies the total number of seconds after the alert triggering event for which images will be included in alert notifications. The number of post-alert images that are captured is equal to the Post-Alert Capture Time multiplied by the Rate value. Note that the individual alert actions may specify a Maximum Camera Pictures setting that is less than the total number of images captured in response to an alert. If the total number of pictures captured by the camera (including both post-alert captures and pre-alert captures) is larger than the Maximum Camera Pictures setting for an alert action then the most recent images captured are given preference and included in the alert notification. Note Three alert actions have the Maximum Camera Pictures setting: Send E-mail, Send HTTP POST, and Send Data to FTP Server. Pre-alert Capture Time (seconds) Specifies the total number of seconds prior to the alert triggering event for which images will be included in alert notifications. The number of pre-alert images that are captured is equal to the Pre-Alert Capture Time multiplied by the Maximum Rate value. Note that the individual alert actions may specify a Maximum Camera Pictures setting that is less than the total number of images captured in response to an alert. If the total number of pictures captured by the camera (including both post-alert captures and pre-alert captures) is larger than the Maximum Camera Pictures setting for an alert action then the most recent images captured are given preference and included in the alert notification. Note Three alert actions have the Maximum Camera Pictures setting: Send E-mail, Send HTTP POST, and Send Data to FTP Server. Time delay before capturing (seconds) Specifies the number of seconds between the triggering of the alert and the first picture capture. Include Audio Specifies whether the device should also use either the integrated microphone or an external microphone (if one has been plugged into the external microphone jack on the pod) to capture audio and include it with the alert for the duration of time covered by the alert notification. Note: This option is available only when configuring NetBotz Appliances that are capable of capturing audio. Audio Volume Specifies the volume at which audio will be captured. Summary of Alarm Capture Data Shows a variety of information about the files that will be generated by the camera using the currently selected Capture Settings. The information in this field will update automatically as new settings are specified or selected.  

Select the camera to configure its associated NetBotz Appliance. The cameras listed depend on the Camera Settings option used. Note You can configure the settings for all listed cameras, one at a time: when done configuring one camera, select another camera in this "Select Camera" display. Camera Settings, a NetBotz Appliance Configuration option in the Device menu: all cameras at all monitored NetBotz Appliances. Camera Settings, a right-click NetBotz Appliance Configuration menu option in the Device Groups view: all cameras at all monitored NetBotz Appliances assigned to the selected device group. Camera Settings, a right-click NetBotz Appliance Configuration menu option in the Device View: all selected cameras, or all cameras for the selected NetBotz Appliances. Note When a single camera device is selected, the "Camera Settings" display is accessed directly; when no selected NetBotz Appliance has an associated camera, the Camera Settings option is not available. NetBotz Appliance Camera Settings, a right-click option in the Thumbnails view: all cameras for the selected thumbnails. Note When the thumbnail for only one camera is selected, the "Camera Settings" display is accessed directly.  

    Masking Use this option to create masks that will cause motion in user-specified image areas to be ignored (Motion Mask), or prevent user-specified regions of the image from being seen (Blockout Mask) for the selected camera during alarm and surveillance activities. Note: When switching between the Motion Mask and Blockout Mask tabs, you may notice a difference in the size or resolution of the displayed Camera view. The Blockout Mask shows the entire field of view of the camera, while the Motion Mask shows the current cropped area of the Camera view. If you have limited the view of the camera by zooming in on the displayed image (through the device web interface or the NetBotz Advanced View application), the Motion Mask tab will show only the cropped area. Motion Mask Use this tab to configure the camera's motion sensor to ignore movement that is detected in specified regions of the image capture. Note A motion mask causes the camera to ignore any detected motion in the masked area. If detected motion would normally cause a clip to be generated, the motion mask prevents any action from being taken. These masks are useful if you want to restrict the camera to movement only in a certain area: for example, monitoring an entryway next to a busy corridor. Using a motion mask, you can block off the corridor, so that only motion through the entryway causes a clip to be generated. Element Description Drawing Mode Select the Drawing Mode. Mask: dragging the mouse across the displayed Camera view draws a green masking rectangle. After you release the mouse button, the masking rectangle turns light blue. Any motion that takes place behind the blue rectangle will not trigger a clip. Unmask: dragging the mouse across the displayed Camera view draws a purple rectangle. After you release the mouse button, the rectangle disappears, along with any portion of a masking rectangle that intersects the purple rectangle. You can flip back and forth between modes as many times as you like until the motion mask is defined to your liking. Once you are finished, click Apply to save your changes. If you want to remove the current mask, click Revert Masks. This does not affect masks that you have already saved with the Apply button. If you want to remove an applied mask, use the Unmask mode. Area of Motion Use this setting to specify how large an area of the image must change (as determined by the Sensitivity value) before the changed image is considered movement. A lower Area of Motion value indicates a smaller area and therefore a smaller amount of movement is required to flag a change. Sensitivity Use this setting to specify how much change in a portion of the image will be tolerated before the changed image is considered movement. A lower Sensitivity value indicates less tolerance for change between images. More subtle movements will be marked as a change. Enable Camera Motion Select to enable the camera motion sensor. Show Motion Outline Select to have a dotted-line outline surround any region of a captured image that is determined to be indicative of motion. Blockout Mask Use this tab to configure a selected camera so that specified areas of the image cannot be seen, when that camera is monitored by a NetBotz Appliance that has the Premium Software Module. Element Description Drawing Mode Select the Drawing Mode. Mask: drag the mouse across the displayed Camera view to draw a green masking rectangle. After you release the mouse button, the masking rectangle turns light blue. When the surveillance feed is viewed, the masked area will be covered with a light grey rectangle. Any motion that takes place behind the gray rectangle will not trigger a clip. Unmask: drag the mouse across the displayed Camera view to draw a purple rectangle. After you release the mouse button, the rectangle disappears, along with any portion of a masking rectangle that intersects the purple rectangle. You can flip back and forth between modes as many times as you like until the motion mask is defined to your liking. Once you are finished, click Apply to save your changes. If you want to remove the current mask, click Revert Masks. This does not affect masks that you have already saved with the Apply button. If you want to remove an applied mask, use the Unmask mode.
