AXIS Q1910/-E/AXIS Q1921/-E - Events
Notes:
• Pre-trigger and post-trigger buffers will be lost if the connection to the event server fails
• The maximum length of the pre-/post-buffer depends on the video image size and selected frame rate
• If the pre- or post-buffer is too large for the camera’s internal memory, the buffer length is reduced. If this occurs, an
entry is created in the unit's log file
Continue image upload (unbuffered) – Upload video images for a fixed length of time or for as long as the trigger is active.
The frame rate will be the best possible, but might not be as high as specified under image frequency, especially if uploading
via a slow connection.
Select type – Upload i
mages to an FTP or HTTP server, send images by email or save the video stream to the local storage disk.
Create folder – Images uploaded to FTP and HTTP servers can be saved to designated folders. Folders can for example be
named using the current date and time, see File Naming & Date/Time Formats in the online help.
Base file name – Used t
o name all uploaded images. Add a suffix or use your own file format to give the images unique
names, see File Naming & Date/Time Formats in the online help.
Use stream profile – Select
the stream profile to upload, send as email or save to the local disk.

Camera tampering
The network camera can generate an alarm whenever the camera is repositioned, or when the lens is covered, sprayed, or
severely defocused.
The camera tampering settings are configured on the Ev
ents > Camera Tampering page as described below. For the camera to
send an alarm you must also create an event, see
How to set up a triggered event
, on page 28.
Camera Tampering Settings
The Minimum duration parameter sets the minimum tampering period, that is an alarm will not be triggered until this period
has elapsed, even if the tampering conditions are otherwise met. This can help prevent false alarms for known conditions that
affect the image.
