TCP/IP (Transmission Control Protocol/Internet Protocol)
A communications protocol suite that provides two data transport methods. TCP is a
connection-based protocol that ensures that data arrives intact and complete. UDP is a
connectionless, best effort protocol that simply sends out packets. UDP is typically used for
streaming media, while TCP is used when error-free delivery is required.
Tilt
Camera movement in the vertical direction.
Tri-streaming
A Bosch encoding technology that generates two separate MPEG-4 video streams and one
MJPEG stream simultaneously. This advanced streaming capability enables the user to tune
live viewing and recording requirements independently to meet specific site and enterprise
requirements.
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.
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.
