The Digital Zoom Mode screen allows the digital zoom feature on the Surveyor99
to be disabled (default setting is enabled). When the Zoom In button is held, the
lens magnifies the image to the limit of the 16:1 optical zoom. Releasing the button
and tapping it will enable digital magnification of the image, with each tap
increasing the magnification by 16x.
With digital zoom, the user has the effect of a 128:1 lens (16x is the last optical
setting, followed by 32x, 48x, 64x, 80x, 96x, 112x, and 128x), but this figure can
be deceptive. Digital magnification 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.

Alarm Handling
The Alarm Input Controller menu is used to program the tremendously flexible
alarm processing features of the Surveyor99. This device can intelligently process
and respond to alarms without the need of an external CPU or controller. Many
standalone applications can be built around the processing capability of the
Surveyor99.
For example, a single unit could be placed in the vestibule of a building. Using the
built-in features, the following scenario is easily accomplished. A person walks into
the vestibule from the outside. A door contact on that door triggers the Surveyor99
to take a picture of the person. At the same time, a relay driver completes a circuit,
which locks the inner door, preventing open egress. 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.
When the outside door is fully closed, the buzzer is enabled to allow passage from
the vestibule into the building. All activity has been taped on an event driven VCR,
also triggered by the dome. In the event that a “panic button” is pressed, an auto-
dialer could also be connected to call the police. This illustrates how a single dome
can do the work of several systems in a standalone application.
The first option on the Alarm Input Controller menu, Enable/Disable Input,
determines whether the 4 alarms are active. These alarms may all be turned on
and off individually, useful when a single alarm is malfunctioning, a door is
propped open, or an alarm event is only required on certain dates and times.
Report Enable is a function that allows the user to determine whether local alarms
are processed, and resolved, at the dome, switcher, or both. In the example of the
vestibule, if the “panic button” were connected to a larger system, we could have it
report directly to the CPU and have that camera display on a selected monitor.
Since the door opening is an occurrence that happens all day long, we do not
necessarily want the operator to intervene each time it happens.
The Active Alarm State menu chooses whether individual alarm inputs respond
when contact closures are made or broken (in essence, normally open or normally
closed).
