The settings related to picture in picture can be configured on this page.
[Picture in picture mode]
Select a picture in picture mode from the following settings.
Off: Images are not combined.
Live: Always combines images according to “Picture in picture setting”.
Alarm action 1: Images are combined according to “Picture in picture setting” only when an alarm occurs.
Alarm action 2: In normal operations images are combined according to “Picture in picture setting”. When an alarm occurs, the main image and sub image are switched.
Alarm action 3: In normal operations images are combined according to “Picture in picture setting”. When an alarm occurs, the frame rate is changed.
When “Main: 15fps/ Sub: 15fps” is selected in “Frame rate”, the frame rate changes to “Main: 30fps/ Sub: 1fps”.
When “Main: 30fps/ Sub: 1fps” is selected in “Frame rate”, the frame rate changes to “Main: 15fps/ Sub: 15fps”.
Alarm action 4: Images are not combined under normal operations. When an alarm occurs, a still image of the entire screen is combined.
Default: Off
Note
When the picture in picture function is used, combined JPEG and H.264 images with the following image capture sizes are transmitted.
When “2 mega pixel [16:9]” is selected for “Image capture mode”: 1920x1080
When “1.3 mega pixel [16:9]” is selected for “Image capture mode”: 1280x720
When “1.3 mega pixel [4:3]” is selected for “Image capture mode”: 1280x960
When “Alarm action 1”, “Alarm action 2”, “Alarm action 3”, or “Alarm action 4” is selected, you can return to normal operations after an alarm occurs by clicking the alarm occurrence indication button on the “Live” page.
When “Live”, “Alarm action 1”, “Alarm action 2”, or “Alarm action 3” is selected, the maximum frame rate for H.264(2) is 15fps. To enable a maximum frame rate of 30fps, select “Off” or “Alarm action 4”.
When “Alarm action 2” is selected, the “Frame rate” of “Picture in picture setting” becomes “Main: 15fps/ Sub: 15fps”.
When “Alarm action 3” is selected, the “Display type” of “Picture in picture setting” becomes “Main: Full image/ Sub: Cropped image”.
When “Alarm action 4” is selected, the image displayed in the sub image is updated each time an alarm occurs.
When displayed images in the sub image for “Alarm action 4” use the same image capture size as the images to be transmitted to the FTP server, images to be attached to the alarm E-mail, or images to be saved to the SD memory card, the image displayed in the sub image may be an image of an earlier time than the image displayed for the main image.
Cropping area setting
Configure the cropping area for the screen set for the cropping image in “Display type”. When “VMD alarm per area” is selected for “Alarm trigger”, a cropping area (up to 4 areas) can be configured for each VMD area (up to 4 areas). If any other setting is selected for “Alarm trigger”, only 1 area can be configured.
Drag the mouse over an image to specify an area. The specified area is configured as a cropping area and an outline is displayed. The position of the cropping area can be moved by clicking and holding the configured outline and then moving it.
The width that a cropping area can be set to is between 1/12 or more and 1/2 or less than the width of the entire image. (When using the Extra optical zoom function, the minimum width will become larger than 1/12 of the width of the entire image.)
Click the [Set] button at the very bottom of the screen to fix the area.
[Clear] button
When “VMD alarm per area” is selected for “Alarm trigger”, the selected outlines displayed in red are deleted. If the [Clear] button is clicked when there is only 1 outline, the outline is moved to the default position. In all other cases the [Clear] button is used to return the area set in “Cropping area setting” to its default position.
The [Set] button at the very bottom of the screen must be clicked after clicking the [Clear] button.
[VMD area display] button
Click the [VMD area display] button to display the configured “VMD area”. The corresponding VMD areas and cropping areas are displayed in the same color. Click the [VMD area display] button again to stop displaying the “VMD area”.
By using this function, you can use the “VMD area” setting as a reference when configuring the cropping area.
Picture in picture setting
[Display position of sub image]
Select a sub image display position from the following settings.
Upper left/Lower left/Upper right/Lower right
Default: Lower right
[Display size of sub image]
Select a sub image display size from the following settings.
Large: The sub image is displayed at a size 1/3 of the width of the main screen.
Small: The sub image is displayed at a size 1/4 of the width of the main screen.
Default: Large
[Display type]
Select a display type for combined images from the following settings.
You can select the main image or sub image to be displayed as either a full screen or a cropping screen.
Main: Full image/ Sub: Cropped image or Main: Cropped image/ Sub: Full image
Default: Main: Full image/ Sub: Cropped image
Note
When “Main: Cropped image/ Sub: Full image” is selected, “Frame rate” becomes “Main: 15fps/ Sub: 15fps”.
[Frame rate]
Select a frame rate for combined images from the following settings.
A frame rate for the main image and sub image can be specified.
Main: 15fps/ Sub: 15fps or Main: 30fps/ Sub: 1fps
Default: Main: 15fps/ Sub: 15fps
Note
When “Main: 30fps/ Sub: 1fps” is selected, “Display type” becomes “Main: Full image/ Sub: Cropped image”.
The value set for the JPEG “Refresh interval (JPEG)*” or H.264 “Frame rate*” on the [H.264/JPEG] tab will be given priority for the actual frame rate.
For example, when “30fps” is selected for the H.264 “Frame rate*”, if “Main: 15fps/ Sub: 15fps” is selected, the frame rate operates at a maximum of 15fps. In addition, when “10fps” is selected for the H.264 “Frame rate*”, if “Main: 15fps/ Sub: 15fps” is selected, the frame rate operates at a maximum of 10fps.
Depending on factors such as the network environment, the resolution, the image quality, or the number of computers concurrently accessing the camera, the transmission interval may be longer than the set value.
If images are not delivered in the specified transmission interval, you can make the images be delivered closer to the specified time by lowering the resolution or image quality.
When “Main: 15fps/ Sub: 15fps” is selected, the transmission interval for all images including images with image capture sizes that are not combined is a maximum of 15fps.
[Alarm trigger]
When selecting “Alarm action 1”, “Alarm action 2”, “Alarm action 3”, or “Alarm action 4” in “Picture in picture mode”, you can select what type of alarm to be triggered by.
All/Terminal alarm/VMD alarm/Command alarm/VMD alarm per area
Default: All
When “Alarm setup >>” is clicked, the [Alarm] tab of the “Alarm” page will be displayed. (→13.1 Configure the settings relating to the alarm action [Alarm])
Note
When “VMD alarm per area” is selected, the cropping area corresponding to the VMD area where an alarm was detected is displayed in the sub image.
“VMD alarm per area” can only be selected when “Alarm action 1” is selected for “Picture in picture mode”.
[Set] button
Applies the picture in picture settings.
[Preview screen >>] button
You can check the configured picture in picture image with a still image.

The picture in picture function cannot be used when the cropping function is being used. When using the picture in picture function, select “Off” for “Cropping”.
When the privacy zone and cropping area overlap, the picture in picture function will not operate. Set the cropping area so that it does not overlap the privacy zone.
When the lens distortion compensation function is used at the same time as the picture in picture function, the cropping position of the cropping area may move out of alignment.
If motion is detected in the area where the sub image is being combined, the actual movements cannot be viewed in the image being combined. Check the movements in an image with a different image capture size that is not being combined.
The cropping area may move out of alignment when the “Image capture mode” setting is changed. Make sure to check the cropping area after changing the “Image capture mode” setting.
The cropping area may move out of alignment when the “Extra optical zoom” setting is changed. Make sure to check the cropping area after changing the “Extra optical zoom” setting.
