Perimeter Detection Combined with Intruder Detection

The principle difference between a perimeter detection
system and an intruder detection system is that
the perimeter system is designed to detect burglars before
they enter your home whilst an intruder system will only pick
up the burglar after entry has been made and movement is detected
within a protected area.
Although generally 2½ to 3 times more expensive than
standard intruder detection (depending on the number of opening
windows and doors), Perimeter detection combined with intruder
detection is considered to be the ultimate way to give personal
protection to all occupants along with protecting your valuable
belongings and items that can never be replaced regardless
It is generally accepted statistically that most burglars
will break a small pane of glass or corner of a window to
access the locks on windows and doors and open them to gain
With this system we install virtually invisible magnetic
reed switch contacts on all external doors to help prevent
an intruder from gaining access to your home.
When your security system is set in either full or partial
mode the perimeter of you home becomes an electronic barrier
to the most common entry methods used by burglars.
Perimeter detection is designed to enable you and your pets
to have full freedom of movement within the home with the
system armed in the 'stay' mode.
Any intruder attempting to gain entry to any protected part
of the home would instantly trigger a pre-alarm alarm condition,
which causes all keypads to squeal for approximately 45-60
seconds allowing you time to check the violated area before
the main alarm sirens activate.
This is especially useful when you are sleeping, working,
watching a movie etc., in one end or on another level of a
larger home and an attempted break-in can not be heard.
If you wish, certain windows may be contacted in such a way
as to enable them to be open approximately 75 - 100mm and
still have the system armed. We refer to this method as 'breeze
In this case, if you have left a door open (or in the case
of a breeze-contacted window, open too far), the system will
inform you of which are insecure when you attempt to arm.
Backing all this up are Passive Infra-red (PIR) motion sensors,
which detect the movement of body heat within a room, and
various other forms of sophisticated detection devices which
add to the difficulty for an intruder to defeat.
Motion detection devices come in many forms with the most
common being PIR. There are now available many other forms
of motion detection including PIR/microwave and radar, which,
in the correct environment, are excellent protection devices.
We can also provide Pet immune/friendly motion sensors which
can allow for single pets up to 36 kgs in weight or 4-5 cat
sized pets, (conditions apply).
With the system armed in away, (full), mode, the two main
entry points (generally garage and front door) are on delayed
activation, (normally 60 - 90 seconds), to allow authorised
entry to, or exit from the premises without activating the
alarm. All other zones are programmed to activate immediately
upon the detection of an intruder.
This is all connected to a state-of-the-art main central
processor to form the heart (and brains), of your system with
an in-built digital dialler, zone expansion, automatic alarm
recycle, full self diagnostics including low battery, fail
to communicate, power failures, etc.
We usually situate this panel in a service room or other
such discrete place as fits in with the premises design, provided
conditions within this area are acceptable to the system specifications
of operation, and expander modules are located discretely
within cupboards as required.
These systems are fully partitionable into 8 completely separate
areas and activated by up to 99 four or six digit user access
codes, which will allow you the ability to assign personal
codes to any and all users.
They are fully programmable either locally through the Alphanumeric
or Graphic LCD message display keypads or remotely utilising
the telephone interface, allowing addition or deletion of
codes, programming of area restrictions, adjustable entry
/ exit delays, remote monitoring, and upload / download facilities.
Connection to the telephone line for monitoring and maintenance
is standard practice for all our systems, although the decision
to go 'on-line' for monitoring remains yours.
Although State-of-the-Art, our systems are very easy you
to operate. Arming the system either fully or partially can
be as simple as the press of a button.
Discretely mounted internal piezo sirens are recommended
to provide the dual role of alerting you to smoke detection
and to create an unpleasant environment that will cause an
intruder to leave immediately.
All systems are connected to the anti tamper circuit to prevent
any unauthorised person from interfering with it whether armed
Included in this system is the ability to interface into
the lighting circuits, (using the appropriate switching devices
/ relays [see your electrician]) which will cause lights to
switch on should an activation of the alarm system take place.
Combining all these different forms of technology is what
makes a Security Concepts system such formidable protection
for your home.
