Tilt
Camera movement in the vertical direction.
Tri-streaming
A Bosch encoding technology that generates two separate
U
UTP (Unshielded Twisted Pair)
A variant of twisted pair cabling UTP cable is not surrounded by any shielding. The wires in a twisted pair cable are twisted around each other to minimize interference from the other twisted pairs in the cable. UTP is the primary wire type for telephone usage and the most commonly used type of networking cable.
V
Virtual Masking
A unique Bosch technology that allows for the creation of “invisible” motion masking areas. These invisible masks are similar to privacy zones, but only the AutoDome’s AutoTrack II and Video Motion Detection algorithms can see them. This allows the AutoDome to ignore areas of unwanted motion.
VMD (Video Motion Detection)
An algorithm for motion detection in which the camera compares the current image with a reference image and counts the number of pixels (see Pixel) that have changed between the two images. An alarm is generated when the number of pixel changes exceeds a user- configured threshold.
X
XF-Dynamic
A highly accurate
Z
Zoom
Changing the effective focal length to allow different fields of view to fill the picture area. Zoom can be optical, where the lens is adjusted, or digital, where a portion of the view selected is magnified electronically.
