Description of Equipment
Overall
The DW-1500/ DW-2000 Color Video Water Well Inspection System is equipped with two
cameras in a single housing, each with a wide-angle lens, for viewing down hole and side view
images in water wells or boreholes. Low light level CCD sensors allow the cameras to detect
images with minimal lighting power, as low as 1 LUX.
Light Emitting Diodes (LED’s) are housed in the Camera and provide lighting for the Down Hole
Image and the Side View Image. LED’s are shock proof, and long lasting, providing
approximately 5000 hours of use.
The Video Output from the Camera duplexes with the control signals and power, going down to
the Camera, on a single conductor armored, Kevlar reinforced, coaxial cable. The Camera is
therefore operable only with the R-Cam Control Unit supplied with the System and is not
compatible with other types of closed circuit survey systems.
A single coaxial Cable head Connector on the rear of the Camera is connected to the Cable by a
watertight pressure rated connector.
The R-Cam Control Unit provides all the controls to operate the Camera and Reel Assembly,
equipped with a 9” LCD Color Video Monitor, and embedded DVR with internal memory.
A standalone power generating system, which supplies 115 VAC or 220 VAC (specified at time
of order) must be used to power to the Winch. The Control Unit is then powered by a 12 VDC
power supply from the 12 VDC output plug on the Winch.
Camera
The Camera, shown in Figure 6, electronics and LED lighting are housed in a stainless steel outer
housing (Figure 7 Item 8), which when assembled is water tight at external pressures of 500 PSI.
The Down View Port (Figure 7 Item 5) protects the downhole view lens and LED lighting. The
Side View Pyrex Glass Port (Figure 7 Item 7) protects the side view lens and LED lighting.

Winch
The custom Winch (Figure 8) supplied by Laval Underground Surveys (LUS) is manufactured for
operating LUS video camera systems in water wells, boreholes, etc. The Winch is driven by a
low speed, high torque electric motor (Figure 8 Item 1). Electric motor power sources for Winch
operation are 115V or 220V AC 60/50 Hz (specified at time of order) or an AC generator.
Winch speed and direction are controlled by the variable speed controller built into the Winch
Motor Controller (Figure 8 Item 2).
Counter-Sheave Assembly
A Counter-Sheave Assembly (Figure 8 Item 3) travels back and forth on a Lead Screw to level
the Cable as it winds onto the Spool. The sheave drives an electronic Encoder that provides
input for the footage counter display on the monitor.

Control Unit
The R-CAM XLT Control Unit is a lightweight portable, hard case that houses the 9” LCD Monitor
Video display with DVR and all the necessary electronics, to control and operate the Camera in
a lightweight, portable, hard cover, carrying / storage case.
The front panel controls on the Control Unit are shown in Figure 9.
12 VDC power is supplied to the control unit from the DW-1500/DW-2000 Winch 12 VDC
output.
The ON-OFF Switch (Figure 9 Item 5) routes power to the Camera and the Camera LED lighting
when switched to the ON position.
The FORWARD-REVERSE Switch (Figure 9 Item 6) rotates the Camera’s Side-View and Down-
View images, and is spring loaded to the STOP (center) position when released.
The VIEW-LIGHT Switch (Figure 9 Item 7) controls the image and light to be viewed on the LCD
Monitor, and is spring loaded to the center position when released. Pressing VIEW toggles
between “DOWN VIEW” and “SIDE VIEW” on the Monitor. Pressing LIGHT cycles through 5
preset light intensities or levels. The “DOWN VIEW” light intensity is independent of the “SIDE
VIEW” light intensity and do not have to match.
The CLEAR Switch (Figure 9 Item 8) is used to set the depth counter to zero (000.00f) after
positioning the Camera near the top of the well prior to the start of the survey.
NOTE: THE DW-1500/DW-2000 WINCH MUST BE SUPPLIED BY EITHER 115 VAC OR 220
VAC 60Hz/50 Hz. WINCH INPUT POWER VOLTAGE MUST BE SPECIFIED AT TIME OF ORDER.
NOTE: The REEL CONTROL functions of the Control Unit will NOT operate the Winch Motor
Control Functions and WILL disrupt power to the Camera if switched ON.

Winch Motor Control Functions
The ON-OFF Switch (Figure 10 Item 6) routes power to the Motor Drive controls when switched
to the ON position.
The FORWARD-STOP-REVERSE Switch (Figure 10 Item 1) controls the Cable Drum to either
lower or raise the Camera in the well, and is used in conjunction with the SPEED Control. The
toggle switch in the “STOP” position will prevent the winch from moving in the forward or
reverse direction.
The SPEED Control Dial (Figure 10 Item 2) is used to control the rate at which the Motor Drive
plays out or rewinds the Cable. The speed should always be at MIN to start and then returned
back to MIN to stop the Motor Drive.
NOTE: After individual use, the cable windings will NOT look or lay the same as when the
unit was delivered from the factory. This is normal and expected. It will NOT affect the
proper working of the Cable or Winch.
NOTE: THE WINCH CONTROLS ARE LOCATED ON THE DW-1500/DW-2000 WINCH. THE
REEL CONTROL ON CONTROL UNIT WILL NOT OPERATE THE WINCH MOTOR

Adjustments
Level-Wind Adjustment
If cable windings become uneven, gapped, or bunched, the level-wind Counter-Sheave
Assembly (Figure 11 Item 3) should be adjusted. The metal adjustment Knob (Figure 11 Item 1)
on the end of the Level-Wind Lead Screw (Figure 11 Item 2) engages and disengages to move
the Counter-Sheave Assembly back and forth.
To adjust the level-wind, pull and hold the adjustment Knob (Figure 11 Item 1) out, then turn it
to move the Counter-Sheave Assembly so that the level-wind trails (follows) the cable windings
on the spool. When correctly adjusted, the cable should lay, wrap by wrap, without gaps,
overlays, or bunching.

DVR Guide
The Digital Video Recorder (DVR) records video and audio to USB storage media and can capture
snapshot images on-the-fly without interrupting recording. It has an internal real-time clock with
battery backup that provides date and time information. Videos and snapshots are saved to a folder
called DCIM on the USB devices. The DCIM folder is created if not present. The videos are recorded as
.ts files and the snapshots are .jpeg files. File names are automatically generated by the real-time clock.
The video bit rate can be tailored to match the user requirements and storage capacity.
The recorded audio comes from an internal microphone behind the front panel. The microphone can be
muted from recording if desired. Text overlays reflecting current date and time can be applied to
appear in the recorded video. A single line of user defined text comments can be overlaid in the video.
There are 5 user entered custom text lines.
The DVR has an internal 16GB USB storage device. This internal memory will store at least 8 hours of
video. There is a USB jack on the panel for an external storage device. There is no limit on capacity of
the USB storage devices; however, the devices need to be FAT 32 format. The DVR will simultaneously
record to both the internal and external USB storage devices. When either internal or external memory
becomes full, an on-screen message will prompt the user to address the capacity of the internal or
external memory before the recording option will resume.
There is also a USB jack on the panel for plugging in a standard PC-type USB keyboard. A wireless mini
keyboard is supplied with the DVR. There is a black ‘receiver’ for the provided mini keyboard inserted in
a USB space on the control unit. It will have two letters on it that correlate with the mini keyboard.
Without the receiver plugged into the control unit, the keyboard will not be able to function. NOTE: the
keyboard and its USB receiver are paired and cannot be mixed with another set.
Keyboard Use and Charging
The internal battery is a non-replaceable Polymer Lithium-ion type. If no keys are pressed for more than
3 minutes, the keyboard goes into Sleep Mode. Because of Sleep Mode, the keyboard’s battery will last
many hours and even many days on one charge. The battery will retain a charge in Sleep Mode from
500 to 700 hours. To re-charge the battery, plug the charging cable into the keyboard and into any
standard USB jack. The charging cable can be plugged into the RCAM panel to charge the battery and
simultaneously operate the keyboard; however, the keyboard receiver must be plugged in to either the
RCAM panel or the female-USB jack on the charging cable. The Green Power LED will flash when the
battery power is low. The Red Battery LED will light up when the keyboard is being properly charged.
