• You may also be able to detect heat coming
from your house walls (inside and out).
This may be due to water pipes in the wall,
radiators and other heaters, or even poor
insulation. You can also sometimes get a
heat source trigger from looking at windows
as there can be a big heat differential there.
CAUTION:
Some heat sources you detect may
be VERY HOT, e.g. water pipes. Do NOT touch
heat indicated surfaces.
A fun game to play with your goggles is to get
someone to try a creep up on you in the dark
without detection, they will have to move very
slowly and walk straight at you, any slight
moves to the left or right should trigger the
detector. To try this out, make sure that the
Thermo-Tracking sensor is pointing at the
target persons head at the start and
throughout the game.

Full mode - both night LED’s illuminated and thermal tracking
enabled. With this mode (in darkness) any people/animals that
you are tracking will see your position.
Stealth mode- the night LED’s are turned off and thermal tracking
is enabled. In darkness any people/animals that you are tracking
will not see your position. This mode should ideally be used when
you are stationary and your target is under intense surveillance.
Caution: Be careful moving around in the dark without lights
helping you to see, especially on uneven ground, where objects
are in the way that you may fall over and near water sources like
ponds, lakes and rivers).
So now you are about to discover the thermal world that is all
around us! Interesting objects that can give off thermal traces are:
• Humans.
• Animals.
• Computers and some computer monitors.
• Radiators.
• Water pipes.
• Hot drinks.
• Lights (especially incandescent lamps) – even
when turned off they can emit a thermal trace
for some time as the lamp/tube cools down.
Function Modes
Your detector
senses
heat, but
converting infrared heat (IR) into an
image that the human eye can actually
see is only possible through a process
called thermal imaging. Cameras that
offer this are expensive to buy.
Our bodies radiate and
absorb infrared energy through
the skin. The military uses
infrared sensors to locate and
track human targets.
