Home Security Tips T o Keep Y our Home Safe

Introduction Home Security Systems  Security systems are important features of a modern Home. The earliest home security systems date back to the early 1900s.  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.

Types Of Detectors used in home security Smoke detector Heat Detector Sound Detector

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  Y our 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 T o 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. Dont rely on your automatic garage door opener for security. 4. Create the illusion that you are home. by using timers on lights radios and TVs. Making your residence appear occupied even when no one is home will deter criminals.

1. 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. 2. 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. Y ou can also ask a neighbor to park in your driveway or parking place to make it appear that you are present. 3. Keep some shades and blinds up and curtains open to maintain a normal everyday appearance in your residence. 4. 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. 5. 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. 6. Organize a community watch program to protect your neighborhood. An alert community is a safe community.
