VX and PeCo Units
The units can control domes, also known as PTZ (Pan/Tilt/Zoom) cameras, using a software control panel,
integrated in the interface, which offers the same possibilities as a real handset.
Each dome has its own protocol, hence the application only supports those domes which has been tested
and accepted (refer to our list of available domes in The software control panel
integrated in the application can control the dome telemetry (presets, tours, camera and lens movement) but
not its advanced configuration.
How to install the domes in your units
During the installation process you will need to have some information, so it is recommended to write down
and keep available the following data:
Dome model and manufacturer
Dome identification address (refer to the dome user manual); this is not necessary when
installing a matrix
Camera number (video input) in the unit where you want to connect the dome
Besides the unit and the dome (or domes) you will need a dome protocol adapter to RS232, to connect the
dome to the unit, and the instructions for its correct configuration (refer to the specific manual of your dome).
If you are installing a single dome and it supports RS-232 protocol, you can connect it directly to the VX /
PeCo RS232 serial port.
You can connect the domes to the unit directly or through a supported matrix. Using a matrix you will be able
to get images from different domes (not simultaneously) using only one of the video inputs of the unit. To do
this you have to connect the monitor video output of the matrix to the desired video input of the unit. To
operate one of the domes connected to the matrix you have to chose the associated camera in the selector
of the software handset.
If you are not using a matrix, you can connect as many domes as video inputs
has the unit, but all of them must have the same protocol (same manufacturer).
To select one of the domes use the usual camera selector on the interface
Connecting the domes to the unit
The domes video signal is connected to the unit using the BNC connectors.
The domes are controlled from the VX / Peco via the RS-232 port. Some domes can be
connected directly to the RS-232 port, while others need a protocol converter. In the former
case, only one dome can be connected to the unit. Depending on the dome and converter used,
you will need to configure some parameters (speed, protocol, etc.). Please check the dome user
manual for details.
If the installed dome is able to go to a preset when an alarm is triggered, you can wire a unit
digital output to a digital input in the dome. This way, through the proper configuration, an alarm
wired to the VX / PeCo not only cause the start of recording, also order the dome to move to a
position in order to record the desired zone.
Connecting the domes by using a matrix
The video signals from different domes are connected to the video-inputs of the matrix and the
control output of the matrix to the command inputs of the domes.
The monitor video output is connected from the matrix to one of the video inputs of the VX /
Peco. In case of multiple monitors in the matrix use the output "monitor 1". The RS-232 port is
connected from the VX / Peco to the control or joystick input in the matrix. Depending on the
protocol supported it might be necessary to use a converter.
If you want to record simultaneously from several domes, you will have to connect the video
signal from the domes to the matrix and also to the VX / Peco. In this case, in order to select a
particular dome we will choose the associated camera in the selection window of the interface,
but to control it we will need to change the camera selector in the software handset of the matrix
(as seen before).
How to use a dome
The software keyboard of each dome shows the different options available for each model, the operation is
similar in all cases.
The following features are common to all the domes:
Preset recording: To record a preset you have to write the preset number, press the SAVE
button and when the number apperas in orange press the PRESET button.
PATTERN recording: To record a tour or pattern press the REC button, move the dome in the
desired direction, you can include presets in the route and finally press STOP. To play the
pattern press RUN and to stop it press STOP.
Option keys:
o CLEAR key: It cleans the numeric screen.
o RESET key: It restart the dome and dispays the ID assigned.
o 180º key: It makes a 180º turn from the position where the dome is.
o AUX-ON and AUX-OFF: It activate or deactivate a digital output in the dome if it has
o ZOOM, IRIS and FOCUS key: Increase or decrease the zoom, iris (graduation fo the
lens aperture) and focus. On some models it is possible to fix it automatically.
Local use
In local use domes in addition to the above option offers the possibility of using several specific features:
On Screen Control: In local mode and for the VGA monitor the dome can be controlled with the
mouse when you are in quads or in single view. To activate it, click on the joystick or on the
screen and the mouse cursor will change its appearance and will move to the centre of the
image, showing with arrows the dome motion. To deactivate the On Screen Control click on the
screen with the mouse wheel and it will come back to its normal mode.
Preset names: The first five dome presets can have a name assigned. When clicking on the
“Preset” button a foldout menu appears and you can write a name for each preset. Click on the
number and the dome will move to the programmed position.
Configuration of a dome by OSD (On Screen Display): When the dome supports OSD
configuration, besides the dome joystick a new button that activates/deactivates this
configuration mode appears. The OSD running depends on each type of dome. (This function is
not available for all domes).
A dome can be moved to a fixed preset by using the activation of a digital input. In the column of
the corresponding camera, the alarm input is associated to the number of the preset. When the
input is activated the dome will move.
