help you in getting a deeper understanding of the

concept of debounce time. Example 1 deals with

events creating the same state: The System Info

event occurs and the configured debounce time

starts. During this time another System Info event

occurs. This System Info event is not accepted as

a new event. Example 2 deals with events creating

different states with the same priority: A Motion

Detected event occurs and the configured

debounce time starts. During this time, the

Motion Stopped event with the same priority

occurs. The Motion Stopped event is not accepted

as a new event. Example 3 also deals with events

creating different states with the same priority:

The state of a virtual input is on. The state

priorities for both state changes are identical. At a

specific point in time, the virtual input is switched

off, the debounce time is started. During this

debounce time the virtual input is switched on.

This state change is not accepted as a new event

because it has the same priority. After the

debounce time has elapsed, the virtual input is in

another state. The switch-on gets the time stamp

of the end of the debounce time and no new

debounce time starts. Example 4 deals with

events with different priorities creating different

states: The Motion Detected event occurs and the

configured debounce time starts. During this time

the Motion Stopped event with a higher priority

occurs. The Motion Stopped event is accepted as

a new event but the debounce time does not start

again. Example 5 also deals with events with

different priorities creating different states: The

state of a virtual input is off. The state priority for

switched on is "5", for switched off is "2". At a

specific point in time, the virtual input is switched

on (prio "5"), the debounce time is started. During

this debounce time the virtual input is switched

off (prio "2"). This state change is accepted as a

new event because it has a higher priority. The

debounce time of the first switch-on is continued.

Further state changes are not accepted during

this debounce time.

Decoder

Changes a digital stream to an analog stream, e.g.,

to display digital video on a analog monitor.

Device family

Bosch encoders / IP cameras can belong to one of

the following device families: CPP-ENC , CPP3 ,

CPP4. Each device family uses another hardware

platform with different functionality. CPP4

provides extended support for H.264 and HD

video resolution.

Device Tree

Hierarchical list of all the available devices in the

system.

DNS

Domain Name System. A DNS server converts a

URL (www.myDevice.com, for example) into an IP

address on networks that use the TCP/IP

protocol.

Dual authorization

Security policy that requires two different users to

log on to the Operator Client. Both the users must

be member of a normal Bosch Video Management

System user group. This user group (or these user

groups if the users are members of different user

groups) must be part of a dual authorization

group. A dual authorization group has its own

access rights within Bosch Video Management

System. This dual authorization group should have

more access rights than the normal user group

that the user belongs to. Example: User A is

member of a user group called Group A. User B is

member of Group B. Additionally a dual

authorization group is configured with Group A

and Group B as members. For the users of Group

A, dual authorization is optional, for users of

Group B it is mandatory. When user A logs on, a

second dialog box for confirming the logon is

displayed. In this dialog box, a second user can

log on if he is available. If not, user A can continue

and start the Operator Client. He then has only

the access rights of Group A. When user B logs

on, again a second dialog box for logging on is

displayed. In this dialog box, a second user must

log on. If not, user B cannot start the Operator

Client.

Dual streaming

Dual streaming allows an incoming data stream to

be encoded simultaneously according to two

different, individually configured settings. This

creates two data streams: one for live and pre-

event recording, the other for continuous, motion,

and alarm recording.
