Description of Equipment
Overall
The R-Cam XLT 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 CMOS 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 will provide 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 12 VDC rechargeable Absorbed Glass Mat Battery Pack is used to power the System and
Video Recorder making the entire System completely portable. The Battery Pack will provide
approximately 4-5 hours of operation depending on the amount of Video Recording and/or
Reel usage.
Camera
The Camera, shown in Figure 5, electronics and LED lighting are housed in a stainless steel outer
housing (Figure 5 Item 8), which when assembled is water tight at external pressures of 500 PSI.
The Down View Port (Figure 5 Item 5) protects the downhole view lens and LED lighting. The
Side View Glass Port (Figure 5 Item 7) protects the side view lens and LED lighting.

Reel Assembly
A portable 12 VDC electric powered reel (Figure 6) equipped with a variable speed motor and
1,000 feet (or 1,300 feet for R-Cam 1300) of coaxial cable is used to lower or raise the Camera
in the well. The coaxial cable is lightweight and Kevlar reinforced for strength. A shelf (Figure 6
Item 1) is located on the Reel Assembly to support the R-Cam Control Unit during operation.
An extendable Boom Arm
(Figure 6 Item 2) on the
Reel Assembly supports the
Camera over the well when
lowering or raising the
Camera during the survey.
An Electronic Encoder
(Figure 6 Item 3) is
mounted at the Boom head
and is used to display
accurate footage
information of the
Camera’s depth on the
Control Unit Video
Monitor. When the system
is not in use the Boom Arm
can be repositioned for
easier storage, by simply
removing the locking pin
(Figure 6 Item 4) at the
base of the Boom Arm,
removing and rotating the
Arm 180 degrees, placing
the Arm back on the base
and replacing the pin.
Power Supply
A 12V DC battery (Figure 1 Item 5) housed in a black box with a lifting handle and an external
battery charger are provided with the system. An LCD voltmeter with protective cover is
located on top of the housing.

When fully charged, the voltmeter will read about 13.0. The voltage will decrease during use.
Camera functions will start to diminish when the voltmeter reads 10.0. Expected run time for
the battery is 4 to 5 hours, depending on the amount of motor activity.
The battery supplied with the system is AGM (Absorbed Glass Mat) Battery which uses a special
absorbed electrolyte technology that is superior to conventional lead-acid batteries.
This completely sealed valve-regulated battery eliminates gas emissions and acid leakage for
longer and safer battery operation. This Industrial 12V Battery is maintenance-free, completely
sealed, vibration and freeze resistant, and non-spillable. Battery substitution is the leading
cause of system failures and voids all warranties.
If the system is used frequently, it is recommended to always keeping the battery recharging on
an AC plug indoors when not in use. If the battery is left at low or no charge for an extended
period it will not hold a charge. When charging, ENSURE SURE THE FUSE IS IN THE BATTERY.
When storing the system for an extended period of time, fully charge the battery for 24 hours
using the supplied charging cable. Then remove the fuse and store in a fully-charged state.
Repeat this procedure every 30 days to maintain a healthy battery life.
Control Unit
The R-CAM 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 7.
12 VDC power is supplied to the Control Unit by the Battery (or Emergency Auxiliary Power
cord).
The Reel Control and Power Cables are connected to the Reel Assembly to provide Camera
control, Depth Encoder information, and Drive Motor power and control functions.
NOTE: IN THE EVENT OF A BATTERY PACK FAILURE OR A SURVEY RUNNING LONGER THAN
BATTERY POWER AVAILABLE THE R-CAM SYSTEM CAN BE OPERATED BY USING THE
VEHICLE BATTERY IN CONJUNCTION WITH THE EMERGENCY AUXILIARY POWER CORD
INCLUDED WITH THE R-CAM SYSTEM

10
The VIDEO OUT (Figure 7 Item 2) is available to connect to a DVR (or Auxiliary Equipment) Video
input with a BNC-RCA Cable. BNC-RCA Cables are available for purchase at www.lavalparts.com
and most online retailers.
The CAM CONTROL ON-OFF Switch (Figure 7 Item 5) routes power to the Camera and the
Camera LED lighting when switched to the ON position.
The FORWARD-REVERSE Switch (Figure 7 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 7 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 7 Item 8) is used to set the depth counter to zero (0000.00ft) after
positioning the Camera near the top of the well prior to the start of the survey. Loss of power
to the system will reset the depth counter to zero.
The REEL CONTROL ON-OFF Switch (Figure 7 Item 12) routes power to the Motor Drive controls
when switched to the ON position.
The FORWARD-STOP-REVERSE Switch (Figure 7 Item 10) 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 Reel Assembly from moving in the forward
or reverse direction.
The SPEED Control Dial (Figure 7 Item 11) 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.
For DVR set-up and connections, see DVR GUIDE on page 12
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 Reel Assembly.

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.
