T812 FEATURES
T812 Pan and Tilt Camera Features
The T812 camera features a unique system-feature named ‘Human Perspective
View’ (HPV). Rather than a simple auto-uprighting system as found in other
cameras, the Troglotech T812 camera uses a series of sensors and motors to
view a scene in the same way a human would. This makes interpreting the viewed
scene simpler and ensures that the viewer can pinpoint problems with the
assurance that the orientation is known.
To allow the camera to assume the straight-ahead position and have the picture in
focus quickly, a single key-press centralises the camera and sets the focus to
6”-infinity. The focus control is entirely electronic allowing pre-set-focus to be
realised. After scanning and adjusting the focus to view close-up objects, the
single key-press will quickly allow the operator to resume the survey.
Borehole Mode allows the T812 to be operated when vertical - in this situation the
Human Perspective View is not required - a single key-press switches off HPV and
allows the picture to be rotated using the ZOOM keys - this makes inspection of
Boreholes more intuitive.
Digital Lens Measurements are covered in a separate manual

OPERATION GUIDE
Standard Operation
When the T812 is fitted to the Troglotech T804 push-rod system and the system
switched ON, the T 12 camera will perform a short calibration routine. During
the calibration routine the Tilt mechanism will turn and the picture will rotate on the
T804 screen as the internal picture sensor rotates. After a few seconds the main
rotate mechanism will adjust the camera to an upright position, the pan
mechanism will face forward and the picture will auto-upright. The camera is now
ready for use.
When operating the camera using the
T804 keyboard, the camera can be set
to view straight-ahead and the Focus
pre-set to 6”- infinity by pressing the
‘Centre’ button on the keyboard as
shown to the right here.
Always use this button after operating
the camera pan, tilt and focus controls.

OPERATION GUIDE
Standard Operation Continued
Inspecting damaged joints in pipe-work:
With the camera view set to straight-ahead position
(by pressing the Centre button if required), push the
camera so that the damaged joint is at the edge of
the picture, then use either of the TILT controls to
move the head so that the damaged joint is in the
centre of the picture. Adjust the Focus controls if
needed to achieve a sharp picture
Now use either of the ROT (rotate) controls to
inspect the joint through 360 degrees. During this
operation, the camera picture will remain upright as
the damaged joint is scanned. After scanning, press
the ‘centre’ button to set the focus to 6” - infinity and
the camera pointing straight ahead.
Borehole mode Pressing the button shown to the
right puts the T812 camera into Borehole mode.
This switches OFF the Human Perspective View
and allows the operator to rotate the video picture
using the ZOOM keys. Press CENTRE to enable
Human Perspective View
Maintaining your T812 camera
After completing a survey, return the cam-
era to the T804 coiler and check the LED
and lens windows for debris—remove any
debris with a soft cloth. Adjust the pan po-
sition so that the windows face the camera
body. This will protect the windows during
transit to the next survey.
Do not use any solvents to clean T812
camera as they may damage the camera
seals and remove lubricating greases.
Troglotech T812 Pan & Tilt Camera User Manual Page 6
OPERATION GUIDE
Your T812 camera is supplied with a C-Spanner which is used to separate the
camera into the Camera Head and Rod Adaptor. When used on the T804 Pushrod
system, the camera is always used as a single unit. When fitted on the Troglotech
Tractor System (not yet released), only the Camera Head is required.
If, in normal use, the two assemblies
become loose, they can be mated again
using the spanner as shown here.
The T812 is fitted with a impact-
absorbing buffer to protect the camera.
This is designed to be sacrificial and
will wear down over time.
To ensure that the camera has
continued protection, when the buffer
has been worn it must be replaced as
shown to the right.
There are three recessed Pozi-Drive
screws, remove all three screws to
remove the buffer.
Clean the front of the camera with a
damp cloth before replacing with a new
buffer.
The buffers are available from your
distributor.

FITTING THE WHEELED ADJUSTABLE SKID
Slide the internal adaptor sleeve from the
skid.
To Fit the Adjustable Wheeled Skid:
Remove the three rear Allen bolts that
secure the internal adaptor sleeve
Ensure the rear pogo area of the camera
is free from moisture and debris. Clean if
required.
Screw camera onto T804 camera termi-
nation, ensure that the collar is flush with
the camera.
Ensure that the T804 camera termination
is free of water or debris, clean if re-
quired. It is imperative that the slipring
area is clean and free from moisture.
Slide the internal adaptor sleeve over the
T804 camera termination

FITTING THE WHEELED ADJUSTABLE SKID
Unscrew camera from T804 termination
and internal adaptor tube.
Slide the internal adaptor sleeve over the
T804 termination until it is flush with the
back of the T812 camera.
Tighten 3 x Allen screws onto T804
termination collar. Do not over-tighten
Fit 3 x Allen bolts to secure internal
adaptor sleeve.
Slide the T804 camera termination and
the internal adaptor tube into the skid.
Troglotech T812 Pan & Tilt Camera User Manual Page 9
FITTING THE WHEELED ADJUSTABLE SKID
Tighten camera onto the T804 camera
termination
Slide camera into skid
Set the skid to the correct diameter for
the pipe being surveyed and then lightly
tighten the friction bolts to hold the skid in
position. For pipes between 150mm-
200mm, use the small wheel set.
The system is now ready for surveying.
Lightly tighten 3 x Allen screws onto the
camera body. Do not over-tighten these
screws as this may distort the camera
body
Troglotech T812 Pan & Tilt Camera User Manual Page 10
FITTING BRUSH SKID SET
Fitting Brush Skids
The T 12 must always be used with the full skid set, whether or not the
brushes are fitted. Using the T812 without skids may damage the camera.
The Troglotech skids can be adjusted from 3” (no brushes fitted), through 4” to 6”
by selecting from the two brush sizes.
