Introduction Home Security Systems?

• Security systems are important features of a
  modern Home. The earliest home security systems
  date back to the early 1900's.
• These systems were generally expensive and very
  hard to monitor. In the past 100 years as
  technology has changed, home security systems
  have also changed .
• Early home security systems were very expensive
  and surprisingly ineffective.
• The requirement for an efficient and cost
  effective system to cater the disastrous
  situations and in order to fulfil the security
  concerns of home owners when the user is away
  from home, there was a strong need to develop a
  cost effective and reliable system to satisfy the
  security related needs of occupants.

Smoke Detector

• A smoke detector is a device that senses smoke,
  typically as an indicator of fire. Commercial
  security devices issue a signal to a fire alarm
  control panel as part of a fire alarm system,
  while household detectors, known as smoke alarms,
  generally issue a local audible or visual alarm
  from the detector itself.

Heat Detector

• The pyro-electric sensing is located in order to
  detect unauthorized intruders. It detects the
  heat generated from the human body and sends a
  signal to the PIC notifying a possible intruder
  existence. The electronic circuit uses the CMOS
  LS6511 integrated circuit for detecting motion
  from the PIR sensor and initiating appropriate
  response. The LS6511 includes two staging
  differential amplifier along with a window
  comparator

Sound Detector

• Sound signal is received from microphone.
  Amplified by OP AMP LM358 and then compared with
  fixed DC Voltage. If the amplitude of sound is
  more than threshold value defined by user is
  detected and a high signal is transferred to the
  PIC microcontroller. Here the sensitivity of the
  circuit can be varied changing R4 value. C4 value
  can be varied from 220 to 470nF in order to
  change the circuit speed-response. ICA amplifies
  about 100 times the audio signal picked-up by the
  microphone and drives ICB acting as peak-voltage
  detector.

Home Protection Against burglars

• Your best defense is to create an environment in
  which burglaries are less likely to occur.
• This can be accomplished by methods of physical
  security, the outside appearance of your
  residence, and by neighborhood and police
  cooperation.

Home Entry Points To Secure

• Doors For external doors and doorframes, opt
  for solid wood or steel. Avoid leaving gaps
  around the doorframe, as this provides leverage
  for removing the door from its frame. Hinges
  should be positioned on the inside of the door so
  that a thief with a screwdriver will be unable to
  remove the entire door.
• Deadbolt Locks A "Thumb Turn Deadlock" can be
  used on all exterior doors where windows are not
  in or near the door. Exterior doors should be of
  "solid core" construction. The bolt should have
  at least a one inch "case hardened" throw and the
  strike plate must be attached securely through
  the door frame into the home structure using at
  least 1-1/2 inch "case hardened" screws.
• Sliding Glass Doors The most inexpensive way to
  secure a sliding glass door is to insert 1-1/2
  inch pan head (large head) sheet metal screws
  into the top of the doorframe at both ends and in
  the middle. Adjust the screws so that the door
  barely clears them when it is operated. This will
  keep the door from being lifted and removed from
  the track and from being forced open. In
  addition, place a metal or solid wood rod on the
  inside track to hold the door closed. The most
  effective protection for this type of door is a
  sliding bolt with a locking device.
• Porch or Patio Doors Treat porch and patio doors
  as any other outside door. Since they are usually
  more hidden from view from the street or by your
  neighbors, extra care should be used to secure
  them.

Analysis From experienced Burglars

• Often a burglar will drive or walk through a
  subdivision looking for a home that appears
  unoccupied. This can be determined by clues such
  as an open garage without cars, an accumulation
  of mail or newspapers, packages left at the front
  door, or notes stuck on the door. The burglar
  will then approach the residence and ring the
  doorbell. If a resident answers, the burglar may
  pretend to be lost and ask for directions.
• If you have someone approach your home in this
  manner, call the police immediately. Try to get a
  description of the person and any involved
  vehicle, along with a license plate number if
  possible to pass on to the police. The police
  will verify the story and offer any necessary
  assistance.

Some Necessary Security Tips

1. Keep all doors and windows closed and securely
   fastened. An open window or door is an open
   invitation for burglars. Thieves are also quick
   to spot weak locks that may be easily forced
   open. Doors should have deadbolt locks with a one
   inch throw and reinforced strike plate with three
   inch screws. All windows should have window
   locks.
2. Secure sliding glass doors. Place a metal rod or
   piece of plywood in the track and install
   vertical bolts. These will help prevent burglars
   from forcing the door open or lifting it off the
   track.
3. Always lock the door to an attached garage. Don't
   rely on your automatic garage door opener for
   security.
4. Create the illusion that you are home. by using
   timers on lights, radios and TV's. Making your
   residence appear occupied, even when no one is
   home, will deter criminals.

• Keep the perimeter of your home well lighted.
  Installing low voltage outdoor lighting is a
  cost-effective way to discourage intruders, as
  well as highlight a house.
• Never leave clues that you are away on a trip.
  Have a trusted neighbor collect mail and
  newspapers while you are away so delivered items
  do not accumulate. You can also ask a neighbor to
  park in your driveway or parking place to make it
  appear that you are present.
• Keep some shades and blinds up and curtains open
  to maintain a normal, everyday appearance in your
  residence.
• Never leave a message on your telephone answering
  machine telling people that you are away from
  home. A message that you will return at a certain
  time leaves your home vulnerable in the interim.
• Keep shrubbery trimmed away from entrances and
  walkways. While large, ornate hedges may be
  beautiful, they also provide a hiding place for
  burglars who need only a minute to break in
  through a window or door.
• Organize a community watch program to protect
  your neighborhood. An alert community is a safe
  community.
