The system can be broken down into four sub-assem-
blies: camera head, reel/dolly, interconnect cord, and
Monitor + VCR/power pack. The Monitor
pack is powered by any 120 or 230 volt AC source. In
turn, they convert this power to ~12 volt DC to power
the camera head and LED lighting, as well as any
options in the system. Other than the controls found
on the Monitor + VCR/power pack for such things as
brightness, contrast, and LED lighting, the system has
no external buttons or dials.
The 12 volts DC for the camera (and options) is fed to
the reel through the interconnect cord that is stored on
the dolly. There are three conductors within this cable
that terminate to pins (male) and sockets (female) in
the connectors. See Figure 1 for a detailed description.
Pins/sockets #1 and #2 are the supply and return for
the 12 volts DC. Pins/sockets #3 are the return path for
the video signal generated by the camera back to the
monitor/ power pack. The connectors on this cable are
the same type that are found at the camera head, push
cable, and any options.
The interconnect cord plugs into the back side of the
reel into an area called the hub. Inside the hub, there
is a device called a slip ring, a kind of rotating electri-
cal joint. The slip ring allows the reel to spin without
twisting the cables that enter/exit the reel, while allow-
ing power and video signals to pass.
The push cable is connected to the slip ring by anoth-
er connector inside the reel, on the cone-shaped por-
tion. This is the "dry end" of the push cable. The
power and video signals travel within the push cable
to and from the camera head. At the "wet end" of the
push cable, a transition occurs from the stiff rod to a
flexible coil cord within the spring. This cord has
another connector that is held into the back of the
camera with a locking sleeve. There are also two
stainless steel safety cables within the spring which
prevent the spring from overstretching when pulling
the camera from pipe.
Once the 12 volt DC power enters the camera, it
passes through a circuit board that directs it to either
the actual video module, or the lights. There is also
some protective circuitry to minimize electronic failure.
The camera circuitry processes images it receives
through the sapphire window and converts it to a
standard video signal that returns to your monitor for
display. If you have a separate power pack, this signal
exits the pack through a video out jack to the monitor
you have chosen to use.

There are several pairs of these connectors in the
system: camera - push cable, push cable - hub, hub -
interconnect cord, interconnect cord - Monitor
power pack. The above designations are always true
for these connectors. Guide pins are always a differ-
ent color than circuit pins, and guide sockets are a dif-
ferent size than the other sockets. Align guide pins to
guide sockets, ensuring the remaining pins and sock-
ets are aligned, and push straight together. To unplug,
pull straight out. Wiggle the connector a little, if neces-
sary, but DO NOT bend or twist it!
