The Digital Zoom Mode screen allows the digital zoom feature on the
S2800e to be disabled (default setting is enabled). When the Zoom In
button is held, the lens magnifies the image to the limit of the 22:1, 23:1
or 35:1 optical zoom, depending on the camera type. Releasing the
button and pressing it will enable infinitely variable digital magnification
of the image.
With digital zoom, the user has the effect of a 264:1, 276:1 or 420:1
lens. Digital magnification, however, cannot add any resolution to the
picture. With each increase in the digital magnification, the picture gets
noisier and loses clarity. Disabling the digital zoom prevents the user
from going into a “digitally enhanced” mode in applications where it is
not desirable.
The Video Defaults menu sets all the camera video settings to the
default settings without affecting other functions, such as presets and
privacy masks. Setting the video defaults will cause the dome to reboot.
Alarm Handling
The S2800e holds the following alarm and relay signals:
• Four local alarm signals available on the TB2 connector, on the main interface board
• One local relay signal on the TB4 connector, on the main interface board
• One Nextiva alarm and one Nextiva relay on the Verint mezzanine board
To use the Nextiva alarm into the Nextiva software, connect it to the relay on the TB4 connector. This way,
you will be able to use the IntelliFlow automated rule engine to create scenarios and responses based on the
state of these Nextiva signals. For the connection procedure, refer to the Nextiva S2800e Series User Guide.
To program the four local alarms located on the TB2 terminal block, use the Alarm Input Controller
programming menu. The S2800e can intelligently process and respond to these four alarms without the need
of an external CPU or controller. Many standalone applications can be built around this processing capability.
For example, a single camera could be placed in the vestibule of a building. A person walks into the vestibule
from the outside. A door contact on that door triggers the S2800e to take a picture of the person. At the same
time, a relay driver completes a circuit, which locks the inner door, preventing open exit. Once in the
vestibule, a motion detector connected to the dome senses that the person has moved over to the intercom
and turns a brighter light on in the vestibule. The dome moves over to a shot of the intercom, allowing us to
clearly see which call button is pressed.
