Why Outdoors?
  • Alerts you to an intruders presence, before they
    get inside
  • Provides extra security for your property and
  • Ideal for residential outdoor applications
  • balconies, patios, courtyards and driveways
  • Ideal for commercial outdoor applications
  • parking area, storage facility, loading dock and
  • Activates security devices
  • lights, chimes, sirens, CCTV cameras, strobe
    lights, etc.

Challenges of the Outdoors
  • Provides the same reliability as a
    high-performance indoor motion detector while
    overcoming potential outdoor disturbances that
    could affect detector performance
  • Water, ice and snow
  • Wind, dirt, dust and insects
  • Extreme temperatures (hot or cold) -35C to
  • Sunlight
  • Electromagnetic and radio-frequency interference

Presentation Overview
  • In this presentation we will review the following
    main topics
  • Physical construction
  • Pet immunity or pet friendly detection
  • Other DG85W features
  • Advanced digital detection system
  • Installation recommendations

Physical Construction
  • Resists water, snow, wind, dust and insects
  • Injected Rubber Gasket
  • A special rubber gasket is injected into the
    casing to effectively isolate the unit on all
  • Unique in the industry
  • Second rubber gasket
  • Another rubber gasket is placed around the lens's
    mask for additional weatherproofing
  • Plastic PCB cover
  • Protects important part of electronic circuit on
    both sides of PC board
  • Rubber foam
  • Seals the wire entry

Impact and Temperature Resistant
  • Casing made from ABS polycarbonate
  • Combining these two plastic materials makes the
    casing much harder and therefore more resistant
    to impact and extreme temperatures
  • Withstands temperatures as low as -35?C (-31?F)
  • The DG85W continued to perform extremely well in
    our Canadian winters
  • Withstands temperatures as high as 50?C (122?F)
  • This specification must be respected as detection
    will be reduced after 50?C
  • Recessed lens with protective mask
  • Reduces the probability of damage from objects
    that can harm the lens (e.g. ball or machinery)

Lens Material
  • Special Poly IR 9 material with a thickness of
    0.5mm provides
  • Additional UV protection
  • Resistance to discoloration and deterioration
  • A surface that repels dirt and is easier to clean

Dual Optical Filtering System
  • Additional special filters for both sensors
  • Blocks out visible light (e.g. sunlight or car
  • Allows only infrared light to pass through (e.g.
    body heat)

Unique Bezel Design
  • The sensors pass through the bezel opening,
    completely isolating them from the area where air
    or insects may be able to enter (i.e. screw or
    wire entry)

  • Why did we choose this colour?
  • Lowers the internal temperature of the detector
  • Because it looks great!

Patented Pet Immunity
Why Pet Immunity?
  • In outdoor applications, animal immunity is vital
  • Pets, roaming animals, birds and rodents pose a
    potential risk for false alarms
  • Outdoor motion detectors must be able to
    differentiate between animals and humans

DG85W Patented Pet Immunity
  • DG85W is immune to pets weighing up to 40kg or a
    target size of 700mm X 900mm
  • This is accomplished using
  • Patented Digital Motion Detection
  • Two dual-opposed infrared sensors
  • A specially designed lens pattern
  • We will discuss this technology in the following

Two Dual Opposed Infrared Sensors
  • The upper and lower sensor are opposed
  • The human body generates an equally positive and
    negative signal pattern

Two Dual Opposed Infrared Sensors
  • Unlike a human body, an animal does not generate
    an equally positive/negative signal pattern
  • Generally one sensor generates a stronger signal
    than the other

Pet Immunity
Pet Friendly
Specially Designed Lens
  • Beams from the upper and lower sensor are
    interlaced to ensure better coverage
  • Generates 64 coverage zones

Pet immune lens
Pet alley lens
Other DG85W Features
Two Operational Modes
  • DGP2 Mode (addressable)
  • Connects directly to a Digiplex (DGP-848 or
    DGP-NE96) 4-wire combus
  • Communicates its alarm and tamper signals, data
    and settings via the combus
  • In this mode, the relay remains active and can be
    used to activate other devices
  • Relay Mode (conventional)
  • Functions like any conventional motion detector
  • Communicates its alarm and tamper signals via

Adjustable Sensitivity
  • Multi-level
  • 11 sensitivity settings
  • Remote adjustment
  • Unique in the industry
  • Adjust settings remotely using a keypad or the
    WinLoad software
  • Can also be adjusted locally

Metal Shield
  • Metal shield covers parts of electronic circuit
  • Maximizes protection from electromagnetic and
    radio frequency interference

Advanced Digital Detection System
Patented Digital Detection
  • An industry first
  • Completely software driven, this technology
    converts, amplifies and processes the sensors
    low-level signal digitally without any analog
  • Processes the sensors entire signal without any
    saturation or noise
  • Provides increased accuracy, reliability and
    superior false alarm immunity

Dual Opposed Detection
  • Compares the entry and exit signals polarity
  • Only movement signals generate opposed polarity
    signals, which are processed by the software
  • Interference signals generate same-polarity
    signals, which are rejected by the software

Dual Opposed Detection
Patented Digital Auto Pulse Signal Processing
  • Measures energy from each detected signal and
    stores them in memory
  • To generate an alarm, the memory must reach the
    required minimum level
  • With high-level signals (low risk of false
    alarms), the detector generates an alarm,
    functioning as a "non-pulse count" detector
  • With low-level signals (high risk of false
    alarms), the detector switches to a very high
    pulse count moderesulting in excellent
    protection against false alarms

Patented Digital Auto Pulse Signal Processing
Digital Dual Edge Processing
  • Separates the entry and exit signals
  • The entry signal and the exit signal must reach
    their respective levels, otherwise an alarm is
    not generated.
  • As a result, false alarm immunity is dramatically

Digital Shield Algorithm
  • Real Time DSP (Digital Signal Processing)
  • Digitally amplifies and filters the sensor signal
    in real time
  • Digital filters are accurate and dont add cost
    or hardware components
  • Movement Analysis
  • Measures and calculates the signals parameters
    in real time and then stores them in memory
  • Compares each signal with a reference bank and if
    the signal does not meet movement criteria, it is
  • RFI/EMI Protection
  • Effectively records high-level RF signals without
    clipping or distortion
  • Recognizes RFI/EMI conditions and effectively
    distinguishes between interference signals and
    movement signals

Digital Automatic Temperature Compensation
  • Automatically adjusts the motion detectors
    sensitivity according to the difference between
    the room temperature and body temperature

Installation Recommendations
1.Always use the MG-SB85 bracket when installing
the DG85. a. The bracket ensures better
isolation from heated walls and better
ventilation. b. The field of view can be
adjusted much easier, if needed. c. Make sure
the bracket is securely installed on a
non-movable wall or post. 2. The DG85 will
perform better when installed in shade. (If
possible) a. This will ensure a lower internal
temperature resulting in better processing of the
heat it needs to detect. b. There will be less
manipulation from the suns infrared rays.
3. For optimal performance install the DG85 at a
height of 2.1m. a. Make sure that when installed
at 2.1m the internal setting corresponds to
ensure pet immunity. b. Where there are no pets
the unit can be installed at 1.6 meters. You will
notice that the human detection speed is faster
at this height, but the detection range decreases
to about 8 meters. If more range is needed set
the internal setting closer to 1.1m. c. The
higher the unit the slower the detection and the
bigger the non-detection gap under it becomes.
(1.5m _at_ 2.1m). For SA conditions do not install
the unit higher than 2.6 meters d. The unit
should be installed at 90 degrees to the ground.
If the ground runs at an angle, adjust the unit
at 90 degrees to that angle to ensure pet
immunity. e. Note the different levels of the
ground. If a unit is installed at 2.1m and the
ground level changes to one meter below the unit,
the pet immunity will be compromised at this
level. If the level suddenly becomes lower than
2.1m, poor detection could be expected from that
4. The DG85s viewing planes (beams) must be
terminated on a solid object (background) not
more that 15m away from it a. The PIR needs a
solid background with a slow changing
temperature. It memorizes the background
temperature to ensure stability and to
differentiate between that and the temperature of
a human. b. Do not install the unit facing into
infinity, an open field or overlooking a built-up
area. The background temperature will fluctuate
leaving the unit with an undetermined reference.
This will result in false alarms during warm and
windy conditions. c. Remember that at 2.1m the
PIRs minimum detection range is 11m, but at
night where there is no heat from the sun it may
detect infrared energy more than 100m away. Be
careful not to install the unit on a balcony or
wall facing over the neighbors border or into
traffic. Vehicles engines are hot and can create
large infrared fields that and can trigger the
PIR from far away. d. Trees, hedges and wooden
fences do not totally stop the path of infrared
energy. Neighbors and vehicles could be detected
through this. Pointing it towards a wire or
slotted fence will result in false alarms from
the neighbors movement. e. Be aware of
backgrounds like black walls, tar, zinc plates,
paved areas or any objects that reach high
temperatures. These could slow down or even mask
the PIR from human detection when the same or
higher temperature is reached.
5. When installing the DG85 outdoors set its
pulse count to dual edge processing. a. Dual
edge processing ensures better stability with
false alarms caused by wind. Air moving past the
DG85 carries heat and this could be interpreted
by the PIR as a large moving heat source such as
a human. To combat this problem a dual pyro is
used. Each sensor has two pyros (dual opposed)
situated next to each other, thus there are two
view planes (beams) right next to each other.
When a human passes from left to right or from
right to left past these beams each pyro receives
the same amount of energy, because heat from a
human stays constant. This also indicates the
entry and exit of the detection ensuring movement
sensing. The heat from moving air changes shape
and size and is very unlikely to deliver the same
amount of energy at both these pyros. When the
energy differs a pulse will not be counted. b.
With single edge pulse count, only one pyro needs
energy to be counted as a pulse. Where there is
no or very little wind (enclosed courtyard) this
could be used to ensure faster detection.
6. Adjust the pulse count setting according to
the environment. a. The outdoors has many
conditions that could simulate the movement of
human heat, but if installed correctly these
simulations are usually temporary and caused by
unique temperature combinations. One or two
pulses might be noticed by the PIR and by setting
the pulse count slightly more false alarms could
be eliminated. b. Turn the pulse count pot fully
clock-wise and then back one quarter of the way.
This will give you a pulse count of three and
should be sufficient for most conditions if
installed correctly. If false alarms occur adjust
the pulse count to a maximum of 5. c. To check
what the pulse count is set to, push down on the
tamper switch and the LED will flash. If it
flashes 7 times, subtract this from 10 and the
pulse count is thus 3. d. The minimum movement
and heat detection on the DG85 on Dual processing
is 1,4m across the field view at 2m from the
detector and is doubled at 11m .eg (7/10
sensitivity 1,4m of movement ) ( 5/10
sensitivity 2,5m of movement ) 1/10 sensitivity
3,5m of movement )
7. The DG85 should be installed facing the
protected area. a. The DG85 counts pulses as it
detects the movement of heat from left to right
and from right to left. Considering this it is
better to install the PIR facing the path towards
the protected area or the area itself. The
intruder should cross the PIRs field of view.
Pointing the unit towards the building (house)
ensures for better termination as well. b. When
installing the DG85 facing down an alley only a
few beams will cover the area depending on the
width of the alley. Consider the above mentioned
when positioning the PIR.
8. The DG85 should not trigger from the infrared
energy radiated from animals of up to 40KG.
(Installed at 2.1 meters at 90 degrees to the
ground level) a. The PIR cannot weight anything
and this is just a reference. The size, shape and
posture of an animal determine how many view
planes it covers at once at any given moment. b.
There are dogs of 50 kg that might not be
detected and dogs of 25 kg could trigger the
DG85. Some dogs are bred for cold conditions and
cloaked by long hair, causing the size of the
infrared energy to appear smaller. On the other
hand shorthaired dogs, especially darker ones
radiate much more heat appearing larger. (Boxers,
Dobermans etc.) c. The best method is to measure
the animal, if the animal is longer than 90cm and
taller than 70cm you should rather opt for the
DG85 with the pet-alley lens. Always take point
b. into consideration. d. Two or more dogs with
a combined weight of more than 40kg will activate
the PIR and the DG85 with pet-lens should rather
be used. e. You will find that the unit will
even activate with children weighing less than
40kg due to their upright posture. The DG85 is
designed to detect vertically moving heat sources
better than horizontal ones. This is how it
achieves pet immunity. If bigger animals jump
against walls or into the air, activations might
occur, but should be rectified with an increased
pulse count setting. f. Large plant leaves
(Palms, Strelitzia, Delicious Monster), which
move around in the wind, could cause activations.
At 11m they should not move more than 1m from
side to side, if closer the movement should be
less. g. Washing moving in the wind during the
day, especially large sheets could cause false
alarms. Be aware of rotisserie lines, which move
over a greater area.
9. The DG85 is only pet immune from 2 meters away
from its view pattern. a. The viewing planes
(beams) are closer together nearer to the PIR. If
a cat is one meter in front of the unit it will
appear to the DG85 as a 200kg lion. The cat is
covering more beams than when it is further away.
b. Make sure there are no moving objects or
plants closer than 2 meters from the DG85. Moving
objects or plants in the non-detection tri-angle
(2.1m by 1.5m) right underneath the unit will not
be detected. c. Insects or lizards gaining entry
to the unit could cause false activations. Make
sure the cable entry point is sealed.
10. False Alarms (Although installed correctly)
a. If false alarms occur in the day and at night
the unit is looking over or through borderlines
detecting heat sources outside the property. b.
If false alarms occur in the morning only, the
PIR is looking onto a fast heating object such as
a metal plate. The combination of this and cold
air causes false alarms. c. If false alarms
occur only in the day at different times, change
the view angle of the unit slightly or move it to
another point. Some object in its field of view
is simulating an alarm condition.
