Using post mode
Use the four Post Mode setting options to determine what conditions will trigger the capture of data from the camera.Note: When using a post mode that requires a camera to be triggered by an alert, the camera must be selected by the Camera to Trigger option for the alert threshold that the alert is responding. Right-click the device in the Device or Map View and use an Alert Thresholds option to edit an existing threshold or add a new one.
Disabled
The Disabled option prevents data from the camera from being archived, even during an alert.
You may want to set a camera to Disabled if you need to temporarily disable capture on a camera for a non-repeating interval of time.
Note: If you want to disable capturing for a repeating interval of time, you should use the Surveillance Scheduling option on the "Surveillance Settings" display.
Send Continuously During Alerts
Choose this option if you need to create a complete auditable record of all activity (and non-activity) that occurs for the duration of an alert configured to trigger the camera.
Note
An alert can result in a camera's surveillance data being continuously sent only when that alert is in response to an alert threshold which has that camera selected by that threshold's Camera to Trigger option.
Surveillance events created using the Send Continuously During Alerts mode do not rely on detected movement to determine whether an image should be captured and added to the surveillance clip. Therefore, the resulting clip may be more consistent in terms of time continuity, enabling you to more easily judge the amount of time that passes between movement that occurs in view of the camera.
Note: You may not want to use this setting with alerts that are set to Return to normal requires user input. If a delay occurs before the alert is resolved, this setting can generate very large clips.
You can use the Send Continuously During Alerts mode under the following circumstances:
- You are in a high security environment where you are required to have a complete audit record of all time-stamped images (including those with no detectable changes) while sensors, such as the door switch, camera motion sensor, or external dry contacts are triggered.
- You need to monitor for situations in which the rate or size of the changes in the images may be too small to be detected reliably by the motion sensor capabilities of the device camera (i.e. the blinking of a small light, a person moving very slowly at a distance from the camera).
- You prefer the time interval between frames to be approximately steady (more "real-time"), as opposed to variable (as is the case with motion based), without the frame count limitations of the alerts being an issue.
Send on Motion Detected
Choose this option if you need to create records of any movement that occurs in the installation location, but a visual record of the time that passes between detected motion is not needed.
You can use the Send on Motion Detected setting if:
- You want to create a visual record of all personnel that access an equipment room.
- You want to create a visual record of all personnel that enter or exit through a specific door.
Send on Motion Detected During Alerts
Choose this option if you need to create records of any movement that occurs in the installation location for the duration of an alert configured to trigger the camera, but a visual record of the time that passes between detected motion is not needed.
Note
An alert can result in a camera's surveillance data being sent when motion is detected only when that alert is in response to an alert threshold which has that camera selected by that threshold's Camera to Trigger option.
Unlike surveillance events generated by devices set to Send on Motion Detected mode, devices set to this mode will ignore movement unless it occurs while an alert is being reported by the device.
You could use the Send on Motion Detected During Alerts mode if:
- You want to create a visual record of all personnel that open a specific door and enter or leave a room during specific hours. Using the Surveillance Scheduling option, you could create a record of people entering and leaving a facility between the hours of 8:00PM and 6:00AM, for example, while ignoring entries and exits that occur during normal business hours.
- You want to create a visual record of a room that has been entered illegally, such as by breaking a window that has a dry contact glass break sensor attached to it or by opening a door that is supposed to be used for emergency exits only.
- You want to record images while a transparent rack or equipment room door is open (thereby triggering the Door sensor alert), but do not want to record movement seen though the door while it is closed.
