Stream security
Video authentication
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.
Signature interval [s]
For certain Video authentication modes, enter the interval (in seconds) between insertions of
the digital signature.
4.4.1.2 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.
The height of the camera must always be entered manually. Whenever possible, roll angle and
tilt angle are provided by the camera itself. The focal length is provided, if the camera has a
built-in lens.
Select the appropriate mounting position of the camera. Options that appear depend on the
type of camera.
