e
with factory
settings
that should suit most applications.
By default, when it detects movement, your SLDC2
will automatically
record 2 photographs followed by
a 30 second video clip
.
You can change
these
settings
via
the easy to use menu.
Please refer to the full guide for more information.
Basic s
etup is as easy as A,B,C.

Carefully and without touching
the glass of the bulb
fit the halogen bulb
ensuring you secure the floodlight glass cover afterwards.
NOTE: Halogen bulbs get very hot and contamination from your skin can
cause the glass to break during operation.
We recommend positioning the unit bet
ween 3m and 4m on a sound wall
and angled towards the area of interest so that most traffic crosses the
PIR
zones and triggers your
SLDC2
to start recording.
Good results can also be obtained by
positioning
the
SLDC2
higher and
facing down to the area of
interest
See the section
SLDC2
mounting and the movement sensor
for details.
You can replace an existing outside light or undertake a new installation.

Connect the mains supply.
Your
SLDC2
requires mains power which should already be in place, i
f
not you will need to arrange for a competent and qualified person to
install the necessary cabling.
We recommend you use a switched circuit and that power is turned off
during installation.
Observe correct wiring
failure to do so will
damage the unit and
will
invalidate your warranty.

SLDC2 full u
ser guide
Understanding
your
SLDC2
The
Challenger SLDC2
is a
self-contained
security system that
automatically records both video and digital photographs when
movement is detected.
Because it has a powerful halogen floodlight the
SLDC2
works both day
and night with the added deterrent of
the light to ward off intruders.
Your
SLDC2
can capture digital pictures up to 3 mega-pixels in resolution
or video clips with sound, up to 60 seconds long.
Recordings are
stored
to an SD memory card
. A
free
SD
card is supplied
with your
SLDC2
. You can u
se
up to a 2Gb
card
allowing you to store over
5000 images.
You can recover recordings by retrieving your SD card and viewing the
contents using a PC or digital camera. Alternatively you can use a USB
cable to connect your PC directly to the
SLDC2
and dow
nload recordings
at your convenience.
Y
our
SLDC2
can also work
as a web camera whilst full operation of the
floodlight is maintained. This allows you to view and
make recordings to
your PC and even email or upload images to a web site.

How it works
IM
PORTANT :
Follow the Quick Start Guide to get your
SLDC2
working.
Like a normal motion sensitive floodlight with a Passive Infra Red (PIR)
sensor, if the surrounding light level is low your
SLDC2
floodlight will
come on when a warm object crosses its area
of sensitivity.
Again, like a normal floodlight the light level at which your
SLDC2
operates and the time the light stays on are controlled by the LUX and
Time controls on the underside of the unit.
Unlike a normal floodlight, when motion is detected t
he
SLDC2
will also
record video or photos and you can control the duration and number of
both.
The normal screen of your
SLDC2

Each video and photo is time and date stamped to provide evidence of
when the image was captured.
Your
SLDC2
is fitted
with a backup battery which
should
ensure the clo
ck
continues to operate and all settings are kept in the event of a power
failure.
Whilst we recommend you
check your equipment regularly es
pecially
following a power cut
you
should
only
need
to set
up
your SLDC2 once.

Basic operation
SD
Memory card
Your
SLDC2
will only allow you to record images if an SD card is fitted, or
you are operating it as a web camera and recording directly to your PC.
When no SD card is fitted the display will show No Card
If the unit attempts to record with no card present,
the LED will flash rapidly to warn you.
When you insert an SD card, the
SLDC2
will read the contents of the card
and then display the number of recordings
in this example 160.
To avoid card read
ing problems or system freezes we
recommend you turn the power off when removing
and installing an SD card.
F
it
your
SD card into the slot provided. Ensure you insert the card with
the metal contact end in first and with these contacts facing the front
(c
amera
end
) of the unit. The card should click
easily
into place.
Page 17
Page No. 19
SLDC2 User Guide
Issue 1.0
Recording format
Even if you insert a blank SD card, the
SLDC2
will automatically create a
directory called DCIM and store your recordings in this directory.
This allows you to access the
recordings using a PC or a digital camera.
Photographs are stored in the .jpeg format with the reference
SEC_XXXX.JPG where XXXX is the number for that recording
Videos are stored in the .avi format with the reference
SEC_XXXX.AVI where XXXX is the nu
mber for that recording
The SEC prefix denotes SECurity recording, allowing you to identify those
photos and videos taken by your
SLDC2
.
The
SLDC2
will start the
recording
number based on the number of
recordings already on the SD card fitted e.g. if the
re are 10 recordings,
the next photo will be SEC_0011.JPG and so on.
If there are no recordings on the SD card, the
SLDC2
will re-
start
numbering
at SEC_0001.JPG

Floodlight
light level
The light level at which the floodlight com
es on is controlled in
two ways
and is set
using the Floodlight menu from within the Main Setup.
Auto
The light is turned on when the camera
needs it and for as long as recording lasts.
LUX
The light is turned on based on the
setting of the LUX
and Time
control
.
When set t
o LUX mode, you can adjust the light level at which the
floodlight comes on by changing the position of the LUX setting on the
underside
of the
SLDC2.
Turn the LUX control to the + setting if you want the floodlight to come
on
in brighter conditions.
Tu
rn the LUX control to the
setting if you want the floodlight to come
on only in very dark conditions.
In AUTO mode, the
LUX and Time
settings are
ignored and the camera decides when
and for how
long the light is turned on.
Page 19
Page No. 21
DC2 User Guide
Issue 1.0
Floodlight on time
When th
e Floodlight menu option is set to LUX t
he time that the
floodlight stays on for is determined by the TIME control of the base of
the
SLDC2
.
Move the TIME control to the
position to set it to minimum on time of
approximately 7 seconds.
Move the TIME co
ntrol to the + position to set it to the maximum on time
of approximately 7 minutes.
When the Floodlight option is set to Auto, the on
time is controlled by the camera. If necessary,
the floodlight will come on and stay on for the
duration of recording r
egardless of the TIME
setting. It will go off approximately 5 seconds
after recording ends.
Arming period
Following power up or after
you exit the main menu
the
LED on your
SLDC2 will flash rapidly for
approximately 1 minute before arming and
becoming re
ady to start recording.
If the LED mode is set to Flash, when the unit is ready to operate
the
LED
will begin flashing
slowly
every 5 seconds.

USB connection
You can connect your
SLDC2
to your PC using the USB lead supplied.
Important
: You must regi
ster your
SLDC2
and install the camera driver
before connecting it to your PC. See the section
Using your
SLDC2
with a
PC
.
Each time you connect the USB lead to your PC
, your
SLDC2 will enter
the mode set in the
USB menu within the
Main Setup menu
.
N
ote
: Automatic re
cording by your
SLDC2
stops
when it is connected
to a PC.
PC Camera
Your
SLDC2
will operate as a PC camera allowing you to
view and record images via your PC.
MSDC (Mass Storage Device Class)
You will be able to access your SD
car
d as a removable disc via your PC.
If your
SLDC2
is recording when you connect the USB lead to your PC, it
will wait to complete the recording before giving you PC access. When
you remove the USB connection from your PC, your
SLDC2
will
automatically reset.
Page 21
Page No. 23
SLDC2 User Guide
Issue 1.0
Whilst the USB standard allows for only limited length cables, it is
possible to
buy
a USB extension cable up to 5m long.
The USB menu
option allows you to leave a USB lead permanently connected
to your
SLDC2 as the unit will behave the same way each t
ime you connect your
computer. If set to MSDC you can access your recordings without having
to recover the SD card. If set to PC Camera you can use
the SLDC2
as a
web
cam
era and record directly to your PC (Additional software
required).
When connected to
your PC, the
SLDC2
draws its power from the PC.
Therefore, in the event of a power failure and assuming your PC still has
power (like a laptop or a computer with an uninterruptible power
supply) your
SLDC2
will continue to operate in either mode.
When
ma
ins power is connected and your
SLDC2
is
operating as a PC
camera
the
floodlight on your
SLDC2
will continue to operate
independently, turning on when movement is detected. In this mode,
the light level at which the floodlight comes on is determined by the
LUX
setting.
Should power fail whilst your
SLDC2
is connected to a PC, the unit will
continue to work as a PC camera or removable disc drive, but the
floodlight will stop operating.
NOTE:
When you disconnect the
SLDC2
from your PC, it will reset.

mounting
and the movement sensor
Passive
Infra Red (PIR) sensors detect changes in infra-red radiation in
the form of heat given off by objects such as people, cars and animals.
The larger the object the more infra-red it emits.
SLDC2
has an angle of
s
ensitivity of approximately 65 degrees and approximately 9m range.
To focus the
energy to its
sensor
SLDC2
uses
a Fresnel lens.
This divides the
area into a number
of zones, both
vertical and
horizontal.
PIR sensors detect
moving hot objects
as they cross zones.
Thus they are most
sensitive to
movement across
the area of
sensitivity and
least sensitive to
movement towards
the sensor.
Page 23

SLDC2 User Guide

We therefore recommend that you position your
SLDC2
at a height of 3
-
4 meters and angled towards the area of interest
so that most traffic
crosses the zones and triggers your
SLDC2
to start recording.
The PIR sensor detects
the difference between
objects and ambient air
temperature and will
only trigger when it
detects a hot object
moving across its zones.
Because of
this the area
of sensitivity will vary
with changes in
temperature and the size
of the object. Your
SLDC2
will become more
sensitive in winter and at
night when the
difference between the
hot object and the
ambient air temperature
is greatest, with
sensit
ivity reducing in
summer and during the
day when the difference
is less.

By default there is always a small delay between taking photos as i
t
takes a small amount of time for your
SLDC2
to store each photo. This is
normal for dig
ital cameras and t
he Burst Delay
setting does not contro
l
the exact time between photos
, it increases that time. The actual delay
is
determined by several factors
described in the section Understanding

Understanding digital images
Additional reading
Your
SLDC2
allows you to take either
videos
or
photos
or both. The
choice depends on what images y
ou are trying to record.
The
SLDC2
uses a single
1.3 Mega-pixel
(Mp) image sensor to capture
both photos and video. This sensor has 1280 unique cells horizon
tally and
1024 cells vertically
. In total it has
1280 x 1024 =
1310720 pixels or
1.3Mp
Each cel
l is capable of
measuring
light
levels and colour
. The camera lens
focuses the image onto the image
sensor and the camera
reads
the light
and colour
level of e
very
cell. It
stores this information as a digital
picture or frame.
Digital video
A digital v
ideo is a succession of
such
digital
frames
played to the viewer
at a certain rate
frames per second. T
he human eye
can distinguish up
to 20 frames
pe
r second
but anything faster
gives the illusion of full
animation. The faster the frame rate, the smooth
er the video but the
more storage it requires.
Similarly the larger the
picture size
the more
storage is required.
The
SLDC2
will automatically decide on the best
frame rate for each recording.

Digital Photos
Whilst digital
photos
cannot capture the action, they are very
good for
providing eviden
ce for identification of people.
Unlike
digital video
where each frame or picture must be small in size to
be recorded and stored
quickly, because speed is not so important when
storing a photo they
can be much larger and contain more
pixels and
hence mo
re
information.

In digital images, the more pixels the better
the resolution
but the larger
the file size
and hence the more memory needed to store each picture.
The
combo mode
on your
SLDC2
gives
you the best of both worlds, a
better resolution
photo f
or evidence with a great video to capture action.
Like all digital cameras, the
SLDC2
uses a method cal
led interpolation to
obtain images that are higher in resolution than the natural resolution of
its image sensor. Interpolation effectively inserts addi
tional pixels of
information into an image and uses clever software to guess what colour
and brightness that pixel should be based on those pixels around it.
The more pixels a digital photo has, the
greater resolution it offers.
Because more pixels means
more
information
, a higher resolution will
be
larger and
therefore
take longer to store.

Digital photo resolution is based on 72 dots per
inch (
dpi). The first
photo
above
is 800 x 600 pixels in size (0.5Mp) and would therefore be
just over 11 inches wide if printed w
ithout any adjustment. T
he second
is picture of the same scene is 2048 x 1536 pixels (3Mp), nearly 2.5 times
the size.
Alth
ough both photos are of the same scene, the second has considerably
more pixels, in fact over 6.5 times more and hence offers much higher
resolution, allowing you to see more detail in the picture.
If
we
scale the lead figure in both photo and compare wit
h a video still
it
is easy to see that more pixels gives more resolution and better
recognition.

However, remember the amount of detail you can resolve in an image
depends on how
close the object of interest is to the
SLDC2
.
Your
SLDC2
can record photos in the following resolutions
High
3 Megapixel
2048 x 1536
Normal 2 Megapixel
1200 x 1600
Medium 1.3 Megapixel
1280 x 1024
Low
0.5 Megapixel
800 x 600
Whilst high resolution phot
os are great, because they contain so much
more information (more pixel data) their file sizes are much larger and
as such they use up more memory on the SD memory card.
Your
SLDC2 can record to an SD card up to 2Gb in size. This
size of card
gives the capacity to store
over 5000 2Mp
photos before
the
SLDC2
starts
to overwrite the oldest recordings.

SD card speed
The size of a photo also affects the time it takes for the
SLDC2
to write
the data to an SD card. Different cards have different write s
peeds
measured in megabits per second (Mb/s).
The faster the card, the less
time it takes for any given size of file to be written to it.
Photo Burst
As discussed above, it takes a small amount of time for your
SLDC2
to
store each photo. The faster the
SD card, the shorter this time will be.
Similarly, the smaller the file size (e.g. a low resolution photo)
the
shorter the write time.
This is normal for digital cameras
.
As the amount of detail in the picture will also affect file size there is no
absolu
te time for how quickly your
SLDC2
can take multiple photos but
to achieve the shortest time possible between
photos when using
burst
mode set
the Burst Delay
to the minimum, set the Photo Resolution to
Low and use a very fast SD memory card.
Similarly, t
aking bursts of high resolution photos will slow your
SLDC2
down and can take up to 5 seconds between shots. This is normal.
