The sapphire window is
held in place with a snap-
ring. This is similar to a
circlip but has no holes at
the ends. The camera front
has a small cut-out (shown
here), this allows a thin-
bladed screwdriver
(1.5mm) to push the snap-
ring upwards and inwards.
The snap-ring may “ping”
out so eye protection
should be used. A spare is
supplied with new windows
in case the original is lost.
Use a cotton-bud with
some Blu-Tak on the end to
get a grip on the face of the
window and pull straight
upwards. The window will
have some resistance to
pulling due to the ‘O’ ring
pressure but should lift
using this method.
Remove the old ‘O’ ring
using a pair of tweezers.
The new ‘O’ ring should be
fitted into the camera front
and the window inserted
into it. Fitting to the window
first may result in damage
to the ‘O’ ring when fitting
into the camera front.
Ensure that the new
sapphire window inner
surface (the smaller end) is
free from all grease and
dust and then push this into
the camera front using a
lint-free cloth.
Due to the air pressure
within the camera and the
‘O’ ring the sapphire
window may show some
resistance. Leave the
window a little proud and
then push the new snap-
ring into the camera front.
Using a pair of small screwdrivers work the snap-ring into the groove as
shown here. The best technique is to get one end of the snap-ring into the
groove while pushing down on the window and then use the other
screwdriver to work the other end into the groove.
Clean the outer face of the window with a soft lint-free cloth.

The T801 camera is designed to operate on a Gatorcam push-rod
system that has a termination suitable for their range of “Gatorcam”
colour cameras. Although the internal electronics are completely different
to the Gatorcam colour camera, the T801 is designed to operate at the
same voltage and current. However, the T801 produces more light output
by utilizing 4
th
generation LED’s and saves energy by using a passive
uprighting system.
The camera is designed to work in 3” pipes and above. The maximum
pipe size is dependant on the material the pipe is constructed from but 9”
– 12” pipes are successfully illuminated as long as the material has good
reflectance.
A 3” – 6” skid set is also available.
The lighting on the T801 camera has at least twice the output of the
Gatorcam camera and you may find that good results can be obtained
with lower settings. The T801 utilises the latest auto-exposure system for
excellent pictures in most pipe sizes and construction.
The lighting is designed to illuminate only the area that the video camera
is viewing, concentrating the lighting to the side of the pipe with a little
light directed further down the pipe. This is achieved by using four LED’s,
two of which are high-power types (5W) and two of low power (1W).
Using this combination the lighting produces the perfect pattern for use in
pipework.
