1.1
Programmable
Features
The Dennard 2055 Dome Camera has a number of features which can be selected by
the system supervisor when the dome is installed. Any of these can be altered
subsequently, at any time, or cancelled altogether as relevant, to give the best
operational responses for any particular application.
These are all invoked or cancelled through on-screen menu structures, described in
section 4, and the settings are then retained in non-volatile memory so that they are not
affected by a loss of power.
The features and what they offer are described below:
1.1.1
Positions
Up to 250 positions can be stored and recalled at any time. Each position stores the
Pan, Tilt, Zoom, and Focus positions as well as the position title.
1.1.2
Position
Titles
Each position title can have up to 20 alphanumeric characters to identify the associated
position uniquely. The default title position lies at the bottom left hand corner of the
video picture, left justified.
These Position Titles only appear at the position they identify: any movement from that
position will remove them.
1.1.3
Sequences
Up to 100 Sequences can be stored and recalled at any time. Each sequence can
contain up to 20 positions together with a ‘dwell’ time at each position (2 - 18 seconds in
increments of 2 seconds: longer delays are set by repeating a position) plus the length
of time (2 - 18 seconds again in 2 second increments) that the dome unit must take to
reach the next position, when the time comes to leave the current position. When the
last position in the sequence is reached, the sequence ‘loops’ back to the first position,
taking the time set in the last position/dwell/time-forward block.
1.1.4
Queues
Up to 50 queues can be stored. The purpose of a queue is to form long sequences
without difficulty in documenting a long ‘thread’ of positions, by effectively forming a
sequence of sequences. Each queue links up to 20 sequences together in the same
way that sequences link positions, except that each entry in the queue contains only a
sequence number and a time which links from the last position in one sequence to the
first position in the next; this time (in queue operation only) replaces the time held in the
last position block in the sequence.
1.1.5
Alarm
Response
Up to 250 Alarm responses can be stored. Each alarm response stores a specified
position, sequence, or queue against an alarm number. This is a very powerful feature,
allowing an unlimited number of domes, or any other device conforming to the Dennard
protocol to invoke a pre-set alarm action from one single loop broadcast command.
