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:
|
| 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. |
