Bosch Video Management System
SNTP Simple Network Time Protocol is a simplified version of NTP (see NTP). SNTP can be used
when the ultimate performance of the full NTP implementation described in RFC 1305 is not
needed or justified. SNTP version 4 is described in RFC 2030 (see RFC).
SSL Secure Sockets Layer. Protocol used to secure applications that need to communicate over a
network.
Subnet mask number
Combined with the IP address number used to identify the network segment your computer is
on. A subnet mask is a 32-bit number written in dotted decimal notation, e.g.
255.255.255.192.
Synchronous replay
Simultaneous playback of archived videos that are synchronized in time.
Task User-programmed behavior that is triggered by specific events (motion detected, doorbell
rung, alarm triggered, etc.) Tasks can be: Control of PTZ cameras, relay outputs, camera
sequences, start of an alarm recording. Typical tasks are for example: An event triggers an
alarm; event executes a Command Script; event is logged; user login is allowed only from 8
a.m. to 5 p.m; execution of a Command Script at 11 p.m.
Task Schedule
Used for scheduling events which can occur in Bosch Video Management System, for example
executing a Command Script. In Events you assign Task Schedules to events. For scheduling
events you can also use Recording Schedules. With a standard Task Schedule you configure
time periods for every day of the week, for holidays, and for exception days. With a recurring
Task Schedule you configure recurring time periods. They can recur every day, every week,
every month, or every year.
TCP/IP Transmission Control Protocol / Internet Protocol. Connection-oriented protocol used to
transmit data over an IP network.
Timeline Part of the Bosch Video Management System user interface. Displays lines as graphical
representations of the recordings of the selected cameras. The Timeline allows you to
navigate through recorded videos.
Trap Term in the SNMP environment for an unrequested message from a monitored device (agent)
to the network monitoring system (manager) about an event in this device.
Trunk line Analog outputs of an analog matrix that are connected to an encoder device. Thereby matrix
video sources can be used in the Bosch Video Management System.
UDP User Datagram Protocol. A connection less protocol used to exchange data over an IP
network. UDP is more efficient than TCP for video transmission because of lower overhead.
Unicast Communication between a single transceiver and a single receiver over a network.
User group User groups are used to define common user attributes, such as permissions, privileges and
PTZ priority. By becoming a member of a group, a user automatically inherits all the attributes
of the group.
