Zone mode
A zone is a remote switching device (multiplexer or DVMRe) that serves a group of cameras. A system can be
divided into as many as 32 independent zones, and each zone can have from 1 to 64 cameras depending on the
type of controlling device. In addition, up to 250 zones can be controlled if all units from 33 to the maximum
can use exactly the same setup parameters as unit 32.
The outputs from the zone’s switching device connect to dedicated monitors directly. Each zone is assigned a
device type (multiplexer or DVMRe) and a size (1 to 32 cameras) and can be assigned a 15-character name.
System controller mode
System controller mode is an extension of standard and hybrid Digiplex modes, a mode that allows use of the
KTD-405 with the HDS (High Density Switch) system controller. In this type of system, each user is assigned
a user number that determines the user’s access privileges for each of the system resources. Users must log on
to the keypad using their assigned user number. The keypad uses the number to ask the system controller for
permission when the user attempts to access a monitor, camera, or other system resource. This is in contrast to
the other operation modes, where permissions are assigned to each keypad and stored in each keypad’s
permanent memory. Otherwise, operation is generally similar to Digiplex or hybrid mode.
To call up a camera in a zone, you must know the
zone number and the camera number (
Figure 4 ).
Refer to Zone receiver site addressing on page 65.
