Chapter 1 Quick start
Safety
Do not use around flammable gas. All electrical equipment can
generate sparks that can ignite flammable gas.
Heads have powerful motors that can pinch, so take care not to
get your hands trapped in the head or cabling.
Keep cables tidy. Use cable ties to keep them out of harm’s way.
Overview
Thank you for using the Police Head from Mark Roberts Motion Control
(MRMC). The system is a robust controller designed for day-in, day-out
use in surveillance environments.
The two-handed controls on the system controller give you precise,
ergonomic, real-time control of the camera direction (pan and tilt and
camera functions (auto-focus and trigger). You can store up to eight
camera direction settings which you can return to later at the touch of a
button.

Powering up and loading the head
There is no power switch on the camera head unit; the power is on
whenever the 24-volt power supply is attached and live. Similarly, there is
no power switch on the joystick control unit; it automatically gets its
power from its USB connection.
When you start MHC on the PC, it will automatically load the operating
software into the camera head unit, assuming that all cables are
connected.

Setting the soft limits
In order to prevent damage to cables and other equipment, you can set
software limits to the range of physical travel of the head movement.
To set the soft limits you use the MHC menu option Settings >
Preferences >Pan and Tilt.
Hint
The soft limits apply to any live motions that you perform with the
system, and to any existing positions that you have recorded
previously. If you tighten the limits, any existing position that is now
outside a limit will be not be accessible. The system will only go as
far as the limit allows.
If an axis is outside its soft limit then you will only be able to move
the axis towards the nearest soft limit.

Chapter 2 Recording and re-using static
camera positions
You can record the current head direction as a single “preset”, and then
return to that preset later at the touch of a button.
You can record up to eight presets on the joystick control unit, and more
in the MHC software, and the system remembers them even if you power
off. The following sections tell you how to record and use static camera
positions on the joystick control unit.
Recording a preset
1. Press the RECORD button.
2. If you haven’t done so already, use the system controls to go
to the camera direction that you want to record.
3. Press one of the eight PRESETS buttons.
The current settings are stored to that PRESETS button.
4. Repeat steps 2 and 3 to record additional presets if you want, using a
different PRESETS button for each position.
As long as you stay in Record mode, pressing one of the PRESETS buttons
will store the current settings to that button, overwriting the previous
settings for that button.
You record, use, and modify
presets by using the RECORD
and PRESETS buttons.

Using a preset
1. Press one of the PRESETS buttons.
The camera points to the position that is stored under that
button.
2. Repeat step 1 to go to any other presets that you want.
As long as you stay in Playback mode, pressing one of the PRESETS
buttons will go to that camera direction.
Modifying a preset
1. Press the PRESET button for the position you want to
modify.
2. When the camera arrives at the preset position, use the
Joystick to fine-tune the settings the way you want.
3. Press RECORD then press the same PRESETS button
again.
The new fine-tuned settings overwrite the previous settings
for that button.
Hint
You do not need to wait until the head finishes going to a
preset position in order to go to another one. For example, if
you press the wrong PRESETS button by mistake you can
rectify it by immediately pressing the correct one. Pressing any
PRESETS button in Playback mode instantly aborts any current
action and goes to the new preset selection.
To immediately stop the head and abort the current action
without going to another preset, press the BACK button.

Appendix 1 Troubleshooting
Typical symptoms, causes, and actions
Symptoms Cause and/or action
Pod head did not
appear connected in
MHC
Check that all cables are connected, and all
devices have power.
Check you have added the correct IP address of
the Pod head in MHC.
If you have connected more than one Pod
heads, connected the MRMC system to
another local network, or moved the Pod head
between networks, check that correct addresses
have been entered in MHC.
A spanner( ) icon
appears with the Pod
head icon in the MHC
Main screen.
This can occur due Pan axis or Tilt axis error.
To resolve this, power cycle the head. The head
will take about 4 seconds to reappear
connected in MHC after power cycle.
