To place a logo on the image, select and upload an uncompressed .bmp file with a maximum
size of 300 x 300 pixels and 256 colors to the camera.
–
Use the drop-down menu to select the position of the logo or to hide it (Off).
Optionally, tick the Underlay with full-width bar box to place a full-width background-bar
beneath the time stamp.
Time stamping
–
Click this check box to display the milliseconds in the time stamp.
Note: This information can be useful for recorded video images, however, it does increase the
processor's computing time.
Alarm mode stamping
–
Enter the message to be displayed on the image in the event of an alarm. The maximum text
length is 32 characters.
Live video indicator
Click the check box to display the Live video indicator, an icon that pulses on the OSD to
show that the video stream is live.
Stream security
Select from the Video authentication drop-down box a method for verifying the integrity of
the video.
If you select Watermarking, all images are marked with an icon. The icon indicates if the
sequence (live or saved) has been manipulated.
If you want to add a digital signature to the transmitted video images to ensure their integrity,
select one of the cryptographic algorithms for this signature.
Set the Signature interval [s] for the selected authentication method.
Click Set to apply the changes.

Positioning
The Positioning feature describes the location of the camera and the perspective in the
camera's field of view.
Perspective information is essential to Video Analytics, as it enables the system to compensate
for the illusory smallness of distant objects.
Only through use of perspective information is it possible to distinguish objects such as
persons, bicycles, cars and trucks, and accurately compute their real size and speeds as they
move through 3D space.
However, to calculate perspective information accurately, the camera must be directed at a
single, flat horizontal plane. Multiple and inclined planes, hills, stairs can falsify perspective
information and produce incorrect object information such as size and speed.
Mounting position
The mounting position describes the perspective information that is also often called
calibration.
In general, the mounting position is determined by the parameters of the camera such as
height, roll angle, tilt angle, and focal length.
