1 DESCRIPTION
This manual describes the installation and operation of the PTZ Integrated Pan & Tilt
Camera System designed by Remote Ocean Systems (ROS). The PTZ is a high-
performance color zoom standard (-01) or high definition (-02) camera system which
incorporates pan and tilt control mechanisms with analog speed control and left/right
dimmable, high-intensity LED lights.
The PTZ camera is illustrated by the installation drawings in the appendix. The camera
housing is constructed of anodized aluminum. It is designed to be operated in
radioactive environments up to 1000 R/hr (5000 R/hr manual focus only) and in
underwater applications to 70 meters water depth. The front window is made of impact-
resistant, optical-grade acrylic. The standard external connector is an IMPULSE
MHDL-24-BCR stainless-steel connector.
The PTZ utilizes a CMOS image sensor coupled with a 10:1 optical zoom lens (12x
digital zoom) for video capture. Auto-Focus and Auto-Exposure are enabled upon
power-up, but can be overridden with manual control at any time.
The PTZ offer 360 degrees continuous rotation on the pan axis by means of an internal
slip ring. Both axes offer variable speed control for precise camera orientation.

3 CAMERA OPERATION
NOTE: BEFORE CONNECTING THE CABLE TO THE CAMERA, CHECK THE
INSIDE OF THE CAMERA'S CONNECTOR AND MAKE SURE THAT THE O-RING IS
PRESENT (SEE Figure 27 ON PAGE 25). IF THIS O-RING HAS FALLEN OUT AND
IS MISSING, WATER MAY LEAK INTO THE CONNECTION CAUSING SHORTS.
3.1 INTERCONNECTION
Electrical connection from the controller to the PTZ camera must be made with the
underwater cable for the system to work.
NOTE: PRIOR TO INTERCONNECTING YOUR CABLE, MAKE SURE THE

75-00952 REV D
7
CONTROLLER IS NOT POWERED OR IN THE OFF POSITION. CONNECTING A
PTZ WHILE THE POWER IS ON MAY CAUSE DAMAGE TO THE PTZ DUE TO
INTERMITTENT VOLTAGE SPIKES.
NOTE: WHEN CONNECTING THE UNDERWATER CABLE TO THE CAMERA,
MAKE SURE THE ALIGNMENT FEATURES ON BOTH CONNECTORS ARE
CORRECTLY POSITIONED, THE CONNECTOR IS FULLY SEATED AND THE
LOCKING SLEEVE IS HAND TIGHT.
3.2 INSTALLATION
The PTZ camera is designed to be adaptable for several different deployment methods.
The camera can be directly mounted using the 4 1/4-20 threaded holes on its mounting
plate. Maximum screw depth is .30" from the top of the mounting plate. Clearance for
the connector is required in any mounting surface. See Figure 5 for mounting
dimensions.
Figure 5: 1/4-20 Mounting and Connector Clearance Dimensions
The camera may also be cable deployed using the optional Cable Deployment Clamp
(Figure 3). When used with the Streamlined Screw Protector (Figure 4), the Cable
Deployment Clamp will maintain a streamlined profile at the top of the camera,
preventing snags when the camera is removed from tight spaces.
To use the Clamp, first slide the Screw Protector onto the cable and connect the cable
to the camera. Place the two halves of the Clamp around the cable so that it rests on
the camera's mounting plate and slide the Screw Protector down over it so that the
hardware in the Screw Protector is aligned with the clearance holes in the Clamp.
Fasten the Screw Protector to the camera's mounting plate, then tighten the two screws
in the Clamp so that it grips onto the cable. When properly installed, the Cable
Deployment Clamp will provide strain relief for the molded connector.

Figure 6: Cable Deployment Clamp Installation
An optional PCI Pole Adapter (Figure 2) is available as well. The cable is routed
through the side of the Pole Adapter, which is fastened to the mounting plate using the
Streamlined Screw Protector.

3.3 EXPOSURE CONTROL
The PTZ Camera provides operation over a wide range of scene illuminations. To
achieve this wide range the camera automatically adjusts Exposure Control through
composite operation of the iris, video gain, and shutter modes. For optimum viewing
results, turn led lights on full and stop down the manual iris until the best picture is

75-00952 REV D

achieved. Exposure control works in steps, the exposure button needs to be pushed
and depressed in the appropriate direction in order to increment or decrement one step.
The camera’s iris, gain, and shutter functions are all controlled by an internal
microprocessor. This automatic mode is normally selected when the camera is turned
on. As illumination is increased from complete darkness, the AGC (automatic gain
control) is the first function to operate from maximum to minimum gain. At the point of
minimum gain the iris begins to function, closing as the illumination continues to
increase. If the illumination continues to increase with the lens fully closed, the camera
goes into a shutter mode where the CMOS sensor is allowed to capture light over
decreasing time intervals as the illumination increases. When the manual exposure
control is actuated, the function changes from automatic to manual mode giving the
operator full control of this function. If the operator wishes to return the camera to
automatic exposure mode, EXP DEC and ZOOM WIDE are to be simultaneously
actuated as indicated on the front panel of the control unit.
3.4 ZOOM CONTROL
The zoom lens operates when the zoom control switch is actuated in the Zoom Tele or
Zoom Wide direction. The zoom function continues until the switch is released by the
user or the lens zoom limit is reached. Tele operates towards increasing focal length
settings providing reduced viewing angles with increased magnification of objects in the
scene.
When zooming towards the tele end from the full wide end, the optical zoom is activated
until the optical zoom limit is reached. Once the optical zoom limit is reached, the digital
zoom will seamlessly take over.
When using the zoom functions of the PTZ Camera system, the operator should be
aware of the change in the minimum object distance (MOD) as the viewing angle
changes. As zoom increases, the MOD increases as well.
3.5 DIGITAL ZOOM CONTROL
The Digital Zoom feature allows the user to decrease the viewing angles and magnify
the scene beyond normal optical zoom. When zooming tele from the wide end of the
zoom range, the camera will use optical zoom until the optical zoom limit is reached. At
this limit the digital zoom will seamlessly take over and further magnify the scene. Note
that as you zoom further into the digital zoom range the picture becomes grainier. For
optimal picture quality, the digital zoom range should not be used.

75-00952 REV D
10
3.6 FOCUS CONTROL
The PTZ camera defaults to the auto-focus mode. The auto-focus provides nearly ideal
focusing when the camera is aimed at a scene. However, there may be instances
when there is a need for focusing on specific features of an object. Operation in a
manual focus mode will be required for such viewing. When the focus control switch is
actuated, the function changes from automatic to manual mode giving the operator full
control of this function. The auto-focus relies on edges to focus. One set of conditions
which may force the operator to switch into manual mode occurs when viewing a
relatively close object that has minimal detail. This occurs because the Auto-Focus
system relies on increasing the sharpness of edges in the viewed image in order to
optimize the focus. If there are no edges to utilize for this auto-focus process, the
camera will not be able to properly compensate and may even tend to "hunt" around the
optimum focus point. Focus hunting may also be caused by low illumination or thermal
currents in the water. If the camera is unable to properly sharpen edges auto-focus
operation will be less than optimal. Switching to manual focus is the best option. To
return to the automatic mode, ZOOM WIDE and FOCUS FAR are to be simultaneously
actuated as indicated on the front panel of the control unit.
3.7 NEGATIVE COLOR VIDEO or BLACK & WHITE CONTROL
Another built in function is the negative color or black & white video effect. This function
is useful when an immediate change in contrast is needed. In negative color video
mode, dark colors will be turned white and light colors, as well as white illumination, will
turn dark. This can allow the user to see details in a shadowed area, like a crack. From
a color picture, to activate the negative color function, ZOOM TELE and FOCUS NEAR
must be toggled simultaneously. From a negative art picture, to activate black & white
function ZOOM TELE and FOCUS NEAR must be toggled simultaneously again.
Toggle ZOOM TELE and FOCUS NEAR simultaneously once again from black & white
picture mode to return to standard color.

4 SERVICE AND REPAIR
NOTE: IT IS RECOMMENDED THAT LOCTITE 222, VIBRA-TITE OR AN
EQUIVALENT THREAD LOCKING COMPOUND BE APPLIED TO ALL FASTENERS
BEFORE THEY ARE INSTALLED.
4.1 CAMERA MODULE REPLACEMENT
Replacement of the PTZ camera module requires the following:
Module Replacement Assembly (75-00958-01, see drawing in Appendix)
#3 Phillips Screw Driver
7/64" Allen Wrench
Silicone O-Ring Grease (included in PTZ Maintenance Kit, 75-00997-01)
To replace the module, follow these steps:
1. Loosen the 4 screws on the back of the camera module housing. The module is
attached to this back piece and will slide out along with it. You will only be able
to pull out the module a few inches while the wire harnesses are still attached to
it.

3. Remove the 1/4-20 screw at the bottom of the module, then remove the module.
Figure 10: Module Removal
4. Set the replacement module on the plastic mounting plate and push it backward
against the tacky gap-pad until the threaded hole in the module lines up with the
screw hole in the mounting plate. This ensures good thermal contact with the
housing.
5. Apply Vibra-tite, or an equivalent thread locking compound, to the 1/4-20 flat
head screw included with the module and screw the module to the mounting
plate.
6. A replacement for the -039 size o-ring shown in Figure 11 is included with the
replacement module. Replacing this o-ring at this time is recommended. Make
sure the o-ring groove is free of dirt and debris. Lubricate the new o-ring with
silicone lubricant and insert into the groove as shown.

7. Make sure there are no fingerprints or foreign matter on the lens of the camera
module before reinserting it into the housing. If necessary, clean it with lens
cleaner and a lint free cloth.
8. Reconnect the two connectors to the camera module and re-insert the module
into the housing. As you insert the module, guide the wires so they sit on top of
the wire management shelf inside the module housing. This will prevent
snagging the next time the module is removed.
9. Make sure that the o-ring is still seated correctly in the groove and that no wires
have been pinched, then re-tighten the 4 screws on the back cover of the module
housing.
10.Connect the PTZ to a controller and test operation of the camera and LEDs prior
to redeploying the camera.
11.Purge the camera. Refer to Section 4.5.2 for the Camera Purge Procedure.
4.2 LED PLATE & CAMERA PORT REPLACEMENT
4.2.1 LED PLATE REPLACEMENT
The integrated LED lights should not need to be replaced often. However, over time the
light from the LEDs will become increasingly blue and light output will be diminished,
which will signal that the LED Plate will need to be replaced.
Replacement of the PTZ LED Plate requires the following:
LED Face Plate Replacement Assembly (75-00959-01, see drawing in Appendix)
3/32" Allen Wrench
Silicone O-Ring Grease (included in PTZ Maintenance Kit, 75-00997-01)
To replace the LED Plate, follow these steps:
1. Loosen the 4 screws and pull off the LED Plate to expose the connector.
Disconnect the inline connector and the LED Plate can be removed.

2. The new LED Face Plate Replacement Assembly includes a replacement -039
size o-ring (shown in Figure 12). Replacing the o-ring at this time is
recommended. Make sure the o-ring groove is free of dirt and debris. Lubricate
the new o-ring with silicone lubricant and insert into the groove as shown.
3. Reconnect the connector to the new LED Plate. When putting the LED Plate
back on the camera module housing, make sure to slide in the wire management
shelf (see Figure 11) under the wires going to the camera module. Be careful not
to damage the wires or pull out the camera's connections.
4. Make sure the o-ring is still correctly seated in the groove and tighten the 4
screws.
5. Connect the PTZ to a controller and test operation of the camera and LEDs prior
to redeploying the camera.
6. Purge the camera. Refer to Section 4.5.2 for the Camera Purge Procedure.
4.2.2 CAMERA PORT REPLACEMENT
NOTE: IF CAMERA MODULE AND LED PLATE ARE BEING REPLACED AT THE
SAME TIME, MAKE SURE THAT THE LED PLATE IS INSTALLED FIRST IN THE
CORRECT ORIENTATION. THE WIRE MANAGEMENT SHELF ON THE INSIDE OF
THE LED PLATE MUST BE INSTALLED TOWARD THE TOP OF THE MODULE
HOUSING WITH THE PORT FACING FORWARD. REFER TO THE ASSEMBLY
DRAWING 75-00953-01 IN THE APPENDIX FOR REFERENCE.
The LED Plate Replacement Assembly comes with a new Camera Port already
installed. However the port can also be replaced independently.
