# Searching And Playing Back In Playback View

Recorded clips cannot only be played in the player, but they can also be searched. The way that you search depends on whether you want to search for specific events within the recorded clips or whether you want to search for events at specific times.

### General Playback View Controls

To search and play back recordings, first activate Playback mode or select the date and time and then use the Previous/Next Image buttons , to browse the recordings; alternatively, you can start the playback using the Forward/Backward Playback buttons .

### General Operation Of The Playback View For MOBOTIX MOVE And ONVIF Cameras

Not all playback capabilities are supported by MOBOTIX MOVE cameras and third-party cameras that provide an ONVIF S-compatible interface. For these cameras, recordings can only be played forward.
Therefore, first select Date/Time (1), and then start playback using Forward Playback (2).

### Performing PTZ Actions In Recordings

You can zoom and move the visible image area not only in live images but also in recorded images (PTZ). This enables you to examine specific image areas more closely while the recorded video stream is playing back. On Dual cameras, the program also shows the slider. Use this slider to show the images of either the right, the left or both image sensors. When playing back the recordings of hemispheric cameras, you can set different display modes .

### Zooming and Moving Image Sections

You can zoom using the slider or the mouse wheel. To see other image areas, you can move the recorded image using the mouse.

### Choosing a Sensor

On Dual cameras, you can opt to see the recordings of the right, the left or both image sensors. To do so, move the slider to the right to (left sensor) or further to the right to (right sensor).

### Subsequent Distortion Correction Of Hemispherical Images

When showing recorded images of hemispheric cameras or cameras with the lenses L12/B016, L23/B036, L25/B041, you can select different display modes. In order to get naturally-looking images, the camera will automatically correct the distortion in these modes. This distortion correction can be refined even further when using the panorama correction. Note that this type of correction only takes place locally. This means that the distortion correction of the recorded images only takes place on this computer. The stored recordings (from the camera or a file server) are not influenced in any way.

#### Selecting The Distortion Correction Mode

- Full image: Shows the entire (distorted) full image.
- Normal: Shows a distortion-corrected image and allows executing PTZ actions.
- Panorama: This option shows the distortion-corrected image of an entire room (corrected 180° panorama view) from the left to the right wall. The aspect ratio (width to height) is 8:3.
- Surround: This option shows four image sections (one for each cardinal direction: N, E, S, W) in one joint view. Note that you can use PTZ actions to modify all four views independently from one another.
- Double panorama: This mode shows a panorama view for the North half of the image and a second panorama view of the South half of the image using an aspect ratio (width to height) of 4:3. This mode only makes sense for a hemispheric camera that is mounted to the ceiling.
- Panorama focus: This display mode combines the panorama view (aspect ratio 8:3) with two smaller images (each with aspect ratio 4:3) in one large image.

Move the slider to the right until you see the desired view. This slider position will be stored automatically until you change it again.

#### Panorama Correction

The distortion-corrected images of the different display modes can be further refined using the panorama correction. Move the slider to the right to and use the mouse to correct the image. To store the corrected setting, click on the slider and hold it until the slider icon briefly appears in the center of the image.

### Browsing Recordings For Event Images

When searching for event images, first select the image playback type:

- Event images: Only shows event images.
- Pre-event images: Shows only the first recorded image for each event.
- Highlighted images: Shows only the images, which had been marked as important before.

Note: This feature is not supported by MOBOTIX MOVE cameras and third-party cameras that provide an ONVIF S-compatible interface. For an overview of how the camera functions differ, see Camera Feature Overview.

1. In the Playback view, select the Playback mode by right-clicking on (1) and selecting the desired mode (2).
2. Browse the recordings using the and buttons. Starting with the current event image, these buttons show the previous or next event image.

### Browsing Recordings For A Specific Date And Time

If you have set up a continuous recording for certain times and you want to check for events during those times, for example, you can limit the search to these times. You can search for events at a given time by using time leaps or time-lapse playback.

#### Searching For A Specific Date And Time

1. Click on Date/Time (1) and enter the date and time to search for.
2. The event image jumps to the event in the recordings that is closest to the specified date and time. Click on Playback .

or

1. Click on the Calendar (2) slider. The date and time will be shown above the slider. Move the slider until you reach the date and time that is closest to the point in time you want to examine. The event image jumps to the event in the recordings with the specified date and time. If such a recording is not available, the event image jumps to the event that is closest to the specified point in time (in the direction of searching). In the latter case, the slider turns read the time difference to the specified point in time is shown above the slider. Click on Playback .
   Hint: The farther away you move the mouse pointer from the slider, the more precise your setting will be.

#### Searching Several Cameras For Persons Or Objects

Scenario: Camera A is overlooking the gate and signals an event. The event image in the Alarm bar shows a delivery truck driving through the gate. You want to know if the truck has also passed the area monitored by camera B.

1. To do so, move the mouse pointer over the event image. Three icons are shown. Open the Playback view mode by clicking on .
2. Play back the recording (end of recording) (1).
3. Drag&drop camera B from the camera bar into the Playback view.
4. The playback automatically selects the recording that follows the end of camera A's recording (2). You can continue this process for any number of cameras.

#### Investigating Multiple Cameras For A Specific Point In Time

You want to know if other cameras have recorded something at a specific point in time:

1. Set the reference time using the Pin button (1).
2. Drag the cameras from the Camera bar (2) one by one.
3. The application shows the event images of each camera that are closest to the specified point in time.

### Limiting The Search Range For An Incident

Scenario: Your camera monitors a parking lot from which a car had been stolen during the day. Follow these steps to locate the event as quickly as possible:

1. Start the Playback mode (right-click on ) and select an interval (e.g., 1 day ).
2. Keep clicking on Previous Image until the car can be seen again in the image.
3. Now select a shorter interval (e.g., 1 hour ).
4. Keep clicking on Next Image until the car has left the frame.
5. Keep on using shorter intervals until you have found the exact point in time of the incident.

Note that you can also use the Forward/Backward Playback buttons to play back using the same time leaps.

Note: This feature is not supported by MOBOTIX MOVE cameras and third-party cameras that provide an ONVIF S-compatible interface. For an overview of how the camera functions differ, see Camera Feature Overview.

### Playing Back Recordings

#### Playing Clips

To play the clips, the play buttons and the playback mode are available in the Command bar of the Playback view. First set the desired mode for playing the recordings, such as event images only or with one hour time-lapse, in the Playback mode.
Next, use the Playback Buttons to browse and play back the images one-by-one or continuously in backward or forward direction.

Note: As mentioned in General Operation Of The Playback View For MOBOTIX MOVE And ONVIF Cameras, playback of recordings is limited when using MOBOTIX MOVE cameras and third-party cameras that provide an ONVIF S-compatible interface. Recordings of these cameras can only be played forward. For an overview of how the camera functions differ, see Camera Feature Overview.

The following table summarizes the actions that you can perform with the playback buttons, depending on the playback mode:

Playback Mode | Playback Buttons
| Complete Recordings |  | Jumps one image backward/forward.
| Plays back all recordings backward/forward.
| Event Recording |  | Jumps to the end/the start of the recorded sequence.
| Plays back until the start/the end of the recorded sequence has been reached.
| Event Images |  | Shows the previous/next image every time you click on the button.
| Pre-alarm Images
| Highlighted Images |  | The previous/next images are shown automatically one after the other.
| 1 day time lapse
| 1 hour time lapse
| 10 minute time lapse
| 1-minute time lapses

#### Setting The Playback Speed

The Playback Speed option allows you to speed up or slow down the playback of a recording. This also applies if you play back a recording backward.

1. Click on Playback Speed. The background of the button turns dark gray.
2. To play the recording forward, left-click and hold the left mouse button and move the mouse pointer to the right. The further you move the mouse pointer down (to the right), the faster the playback speed.
3. To play the recording backward, left-click and hold the left mouse button and move the mouse pointer to the left. Again, the further you move the mouse pointer down (to the left), the faster the playback speed.

#### Precise Positioning by Image

If you want to examine a scene very closely, you can view the recordings one image at a time. To do so, stop playback (click on or ). Now use the two buttons (forward) and (backward) to navigate the images one by one.
