Privacy zones are used so an operator cannot view the scene where the camera lens is
positioned. Whenever an operator positions the camera so that any portion of a
programmed privacy zone would be visible in the video, the video blanks and the title of
the privacy zone is outputted on the video signal. If any portion of more than one
privacy zone would be visible, the title of the lowest numbered zone is displayed. If a
unit is sent to a PreShot that has been programmed so that any portion of a privacy zone
would be visible, the PreShot title and the privacy zone title are displayed on the monitor
and the video is blanked. If a unit is sent to a PreShot and any portion of a privacy zone
would be visible while traveling to the PreShot, the video is blanked when any portion of
a privacy zone would be visible.
The HD6 stores the privacy zone data in nonvolatile Flash memory, which will save the
data when the HD6 is not powered. If privacy zones have been programmed and the
unit loses power, the video is blanked upon power-up until the unit finds home to
prevent any privacy zones being visible. Any command to move the HD6 causes the
unit to find home. If any portion of a privacy zone would be visible when the unit is at its
home position, the video remains blank until the operator manually moves the unit so
that no portion of a privacy zone would be visible.
6.10 ALARM OPERATION
The HD6 has 4 normally open alarm contacts, which can be used to initiate a Preshot,
VectorScan, or PTZ Tour. The alarms are sampled 16 times a second. After the alarm
has been accepted, the HD6 will determine if a function has been programmed for that
alarm, and if that alarm is enabled. If either of those conditions are not met, the alarm
will be discarded. If both conditions are met, however, the alarm will be considered
triggered. If no other alarm is in service, the alarm will be serviced. The function
assigned to the alarm will be performed. The HD6 will stay in the state of this alarm until
it is acknowledged. Any additional alarms that are triggered will not be serviced until the
first alarm is acknowledged. If there is more than 1 alarm waiting to be serviced, they
will be serviced in order of alarm number, starting with the lowest.
An alarm cannot be reactivated until it has been both acknowledged, and the contact
reopened. After acknowledgment and the contact reopening, the cycle can begin again.
There are 3 ways to acknowledge an alarm. The first way is to press the key on the
controller that represents the 'ESC' key. This will send the 'Return to Manual' command
to the HD6. When the HD6 receives this command, it will acknowledge any alarm that is
currently active. The second way to acknowledge an alarm is to take manual control.
This will acknowledge ALL alarms that are present -- even those waiting to be serviced.
The final way is to use the Default Function. The Default Function will run a Preshot,
VectorScan, or PTZ Tour after a user-programmable amount of inactive time. It will also
auto-acknowledge an alarm after this programmable delay. It will acknowledge each
active alarm until all alarms are inactive. At that point, the Default Function will run. If
any new alarms come in after this, the cycle will start again.
