Please Note: This manual covers two product lines; The NiTRO-X 400
Series (utilizing either SDH (up to 32GB) and SDX (over 32GB memory
cards) and the NiTRO 400 series (utilizing SDH (up to 32GB memory
cards). Where there is a distinct difference between the two systems these
differences will be clearly marked in regards as to which system they relate
to.
ongratulations on the purchase of the NiTRO400 series or NiTRO-X 400 series DVR.
These Digital Video Recorders, DVR, are solid state single or quad channel digital video
recorder. Offering H.264 compression, the same compression technique as used in Blue Ray
disk players, which produces crystal clear, best in class, video playback.
Due to its small footprint the NiTRO400 series or NiTRO-X 400 series offers flexible
mounting possibilities. In place of a spinning hard drive video records to a removable SD
memory card. Utilizing state of the art surface mount components the NiTRO 400 series or
NiTRO-X 400 series are built to withstand the shock and vibration of school bus operation.
Keeping with tradition, the NiTRO 400 series or NiTRO-X 400 series includes MaxVIEW
400 viewing software. MaxVIEW 400 viewer is a very easy to use application that allows
users to quickly find the video of interest and save a clip. With the press of a button users can
print images and then send them to qualified staff.

Always use grommets when running the harness through sheet metal holes.
Avoid excessively tight bends especially around metal surfaces.
Use fuse holder and fuse provided on the 12V+ connection.
onnect fuse as close to power source as possible.
Use cable ties to secure harness and fuse holder.
ut power harness to length, removing excess cable.
Use correct terminal size for wire gauge. Always use Butt or Ring Terminal
connectors.
10-12 AWG = Yellow
14-16 AWG = Blue
18-22 AWG = Red
Use ratcheting crimpers for terminal installation.
If grounding to a painted surface, scrape off paint and use ‘star’ washer between terminal
and metal surface.
DO NOT use painted or anodized fasteners.
Before connecting constant power, cut off excess slack.
Before connecting power directly at battery, verify that the system maintains a minimum of
8Volts during engine cranking. Testing requires starting the bus, with a multi-meter
connected to battery. onfirm voltage does not drop below 8V during cranking. If voltage
drops, advise mechanic at bus garage that the batteries may need to be replaced or a
Gatekeeper Systems PowerVault B maybe needed.

•Please refer to the relevant section for your particular model of camera for install
instructions.
•amera mounting locations are to be determined by the district.
•ameras should be mounted to the ceiling whenever possible. Install the foam pad
provided with each camera and use holes as a template. The audio hole on the front of
the camera can be used as a aiming guide for the direction the camera needs to be
facing.
•All camera harnesses must be carefully routed to the NiTRO™ or NiTRO-X unit to avoid
pinching or piercing the shielded camera cable.
•All cables running through holes in sheet metal (ceiling, bulkhead etc.) must be protected
with grommets.
•Ensure included gasket is in place between dome base plate and mounting surface.
When installing multiple cameras, mark camera harness wires so the school district knows
which camera is front and back by looking at the marked Molex output connectors,

1. Disassemble the S-Series camera into its five major parts,
A, B, , D, E and carefully place all parts in a clean work
area.
2. Position the Base Plate (B), in the mounting location.
Ensure that there are no gaps between the Base Plate (B)
and the mounting surface. If there are gaps, relocate the
camera to a position where there are no gaps.
3. Note the location where the camera harness will come
though the bodywork of the vehicle. Drill a 3/8
th
hole in
this location. This 3/8
th
hole MUST be directly in the center
of the Base Plate (B) to allow for the terminal end of the
camera harness to correctly connect to the amera Ball
( ). When access behind the camera is not possible, the
cable can be routed from the side through one of the cut
out notches B1 in the camera base.
4. enter the supplied template guide over the 3/8” hole and
mark the location for the 4 screws used to secure the
camera base to the vehicle. Alternatively, center the
camera base over the 3/8” hole and mark the location of
the 4 screws used to secure the camera base to the
vehicle. In both cases, ensure that one of the camera cut
out notches, B1, is aimed at the viewing target. Drill a
suitable pilot hole to accept a #6 screw for each of the
supplied screws.
5. Remove the backing on the rubber gasket (A) pad exposing the adhesive. Secure the Rubber Gasket,
adhesive side down to the Base Plate (B). The Rubber Gasket is supplied to reduce the possibility of any
rattling noise between the camera and vehicle that may be picked up by the microphone. Using the
supplied Tek Screws, secure the camera base to the vehicle.
6. onnect the amera Ball Molex connector to the
connector at the end of the camera harness. Hold the
amera Ball firmly against the Base Plate with the
Microphone, 1, pointing downwards. Position amera
ollar (D) over amera Ball ( ) with the lens window
centered in the arched cut away in the amera ollar.
7. Hold amera ollar (D) securely while threading on the
Retainer Ring (E) until finger tight. Be careful not to
cross-thread the components.
8. To aim the amera Ball ( ), video from the camera can
be viewed by connecting a monitor to the back of the DVR
“AV-Out” port with a Video Adaptor able.
9. Re-position amera ollar (D) prior to tightening down the Retainer Ring (E) so that it does not interfere
with line of sight of the camera and IR LED’s in the amera Ball ( ). Ensure the amera Ball and Harness
pigtail are not pinched or trapped between the amera Ball ( ) or the Base Plate (B), it must be able to
move freely.

There are two ways in which you can Save a video clip, one using the right-mouse button and
the other method uses the File Menu. Both methods use the same steps to first mark the
video you wish to take a clip of.
1. Pause the video at the point of the video where you want the clip to start from.
2. Single left-click on the Video lip Graph where the yellow cursor bar is located.
3. Drag the mouse to the right, the graph will be
highlighted in green, (A). The Subtitle
information panel will reflect information
regarding the clip being taken. Release mouse
at end point.
4. Right-click on the created green section in the
video clip graph and choose Save lip, or,
choose File, Save Video lip.
