Rosco Vision introduces true HD 1080P video in camera systems for commercial vehicles. The
new Safe-T-Scope® system utilizes the STSM351 7'' inch LCD monitor to display 1080P quality
video from up to 2 AHD (Analog HD) cameras with custom triggering options. The monitor is also
backwards-compatible with the NTSC 960H camera format.
This monitor allows the driver to see obstructions behind the vehicle as well as any other location
based on the positioning of the cameras for added convenience and safety. The monitor auto adjusts
the switches between day and night modes based on ambient light. Moreover, it complies with the
latest FCC(USA) & guidelines when installed properly.
• To prevent electric shock, DO NOT OPEN THE MONITOR CASE. The components inside the
monitor are carrying high voltage. There are no user serviceable parts.
• Avoid exposing monitor to water, rain, moisture etc. The monitor is not waterproof. Any moisture
inside the monitor can cause extensive damage.
• The driver is always responsible for the safe operation of the vehicle at all times. Rosco camera
systems do not replace the need for a skilled, alert, professional driver, observing appropriately, and
using safe driving practices. The driver shall conform with district or company backing policy at all
times.

MONITOR INSTALLATION
Find a mounting location inside the vehicle cabin that is convenient to the driver, and complies with
federal regulations (e.g. center of the dashboard, above the windshield on the ceiling, near the rear
view mirror etc). Installer needs to ensure he/she can drill a hole for the monitor pigtail, and that he/
she can stow the excess cable under a surface near the monitor (under the dash, headliner,etc). The
STSM351 Monitor Kit o󰀨ers 2 options for monitor installation:
DUCK FOOT MOUNT INSTALLATION
• The mounting surface should be large enough to accommodate the duck foot mount, which is
roughly 3x4 inches in size. Note that the duck foot is designed to bend and ex slightly in order to
t smoothly curved surfaces.
• Attach the "duck foot" bracket to the dashboard or to the headline using self tapping screws and/
or adhesive pad.
• Slide the monitor to the "duck foot" mounting tip and secure the monitor using the locking ring on
the mount. Adjust the monitor angle for optimum driver viewing comfort and tighten the knob to x
the monitor angle in place.
U-BRACKET MOUNT INSTALLATION
• Attach the optional sunshade kit.
• Drill a hole for the monitor pigtail and ensure it lines up with the large hole in the center of the U-
bracket. The hole diameter should not be more than 1 inch. Be sure to clear any obstacles before
drilling holes. This hole will be the access point for the power harness.
• Attach the "U" bracket to the dashboard or to the headliner using #8 screws/ hardware appropriate
for the mounting surface material (hardware not provided).
• Fasten monitor to the U-bracket using the provided plastic thumb screws and adjust mounting
angle to allow optimum driver viewing comfort. Firmly secure the viewing angle using the plastic
thumb screws.

• Once the monitor is mounted, if necessary, drill a hole on the monitor mounting surface near
the monitor in which to pass through the monitor pigtail. The hole should be no larger than 1" in
diameter. Be sure to clear any obstacles before drilling holes.
• Connect the black wire of the power harness to chassis ground. See wiring diagram on page 7 for
connections.
• Connect the red wire to an ignition switched accessory (ex. radio) power source and ensure that
the power source can provide operating current above 2A.
• In order to automatically display the rear camera view when shifting into reverse using a backup
camera setup, connect the green trigger wire to the vehicle's reverse light circuit. Ensure the
backup camera is connected to port C1 on the power harness. Similarly, the trigger wires can
be connected to the vehicle's left or right turn signal circuit to get the view of the blind spot while
turning left/right.
• Connect the monitor 4 pin female power connector to the power harness 4 pin male connector.
• The power harness should be completely hidden from the vehicle operators and tied/clamped to
a rigid structure or rigid existing vehicle harness.
• Adhere to a 2 inch bend radius for all cables to prevent damage.
FUEL TANKERS & OTHER SPECIALTY VEHICLES:
• All electrical equipment tted to petroleum vehicles must be connected via battery master switch
and must be isolated from the battery while the vehicles are loading and unloading. For other
specialty vehicles, please check applicable code and regulations prior to installation.
• Always consult your dealer when tting any electrical or electronic equipment to a vehicle tted
with a CAN-bus multiplex system.

PRACTICAL EXAMPLE:
A delay-o󰀨 is useful when using turn signal triggers to activate a blind spot camera. Most vehicles
automatically deactivate the turn signal half-way through a turn. The delay-o󰀨 allows the driver to see
the blind spot camera through the entire turn.
NOTE
• Please read this manual carefully before using the product.
• This system is intended as an aid to safe driving operation.
• Drivers must always use extreme caution when operating a vehicle.
• Specications subject to change without prior notice.
• Keep all cables AWAY from rotating and electrically noisy components.
• Make sure all cables are fastened properly so that you can prevent wire chang, kinks, cuts, etc.
• Always consult your dealer when tting any electrical or electronic equipment to a vehicle tted
with a CAN-bus or multiplex system.
WARNING
• To prevent electrical shock, DO NOT
OPEN MONITOR CASE.
• Avoid exposing monitor to water, rain,
moisture etc.
• Do not disassemble the camera.
This voids the warranty.

1.1 EXAMPLE CAMERA INSTALLATION
Safe-T-Scope 7" AHD Monitor can accommodate up to 2
cameras. These cameras can be installed at the rear of the
vehicle, left/right side of the vehicle or any other location
according to user's wish. An example of camera installation
is given here using the STSC201 Rosco Backup Camera.
INSTALL MOUNTING BRACKET
• Select a high and centered location at the rear of the
vehicle and close to the rear marker lights to mount
the STSC201 camera. This installation location will
ensure that the image transmitted by the camera will
show the rear bumper and area behind the vehicle.
• We do not recommend mounting the camera near
the lower area of the vehicle (eg. the bumper).
This reduces the view of the camera and increas-
es the chance of physical damage to the camera.
• Using the camera mounting bracket as a guide, drill
four pilot screw holes into the vehicle. Be sure to clear
any obstacles(e.g. electrical wiring), etc. before drill-
ing holes. Use a 3/4 drill bit to drill a camera cable hole
into the vehicle close to camera mounting bracket.
INSTALL CAMERA
• Install the camera mounting bracket (vehicle
mounting screws not provided. Use 3/16 sized
hardware appropriate for the mounting sur-
face) Mount the camera and sunshade onto
the bracket using the provided screws. Insert
the camera cable into the vehicle through the
hole and install the cable grommet on the hole.
• Connect the camera cable to the male-pinned
connector of the camera extension cable .
Hand-tighten the coupling ring on the camera
cable to ensure a secure connection, and slide
the environmental boot over the connection.
ROUTE EXTENSION CABLE
• Route the extension cable to the vehicle cabin at
the front of the vehicle and keep the cable away
from hot, rotating, or electrically noisy components.
• Tuck the cable out of sight and secure/clamp the
cable at as many spots as possible to prevent ac-
cidental snagging or damage to the cable.
