To prevent sabotage to your alarm system

Contrary to some crime scenes in TV Modern alarm systems are very well protected against sabotage. The only way to sabotage an alarm system, their manipulation in the disarmed state. Here are a few possibilities of sabotage and how they can be prevented:

Separation of a detector

As between a DC power system and detector, a constant voltage must be applied; an interruption would lead to an immediate alarm. In systems with bus technology, the central control unit immediately detects a missing element and triggers an alarm.

Bridging the detector

In any DC detector is a firmly defined resistance. If these bridges each, eg through a previously already rigged alarm device or via a normal wire, the measured resistance value which is recognized by the Central and evaluated as (sabotage) alarm changes.

Cover of a motion

Modern IR motion has a visual recognition. If they are sprayed with paint or covered with a cardboard or the like, is the altered “view”and reported as a tamper alarm.

Manipulation of the peripheral inside

Theoretically, it would be possible to manipulate the release of a contact detector. However, modern and older elements have a so-called cover contact, which is connected in parallel with the alarm contact or connected to the tamper line. If the housing is opened when armed, the alarm is triggered (“Connection Error”).

Caps of the leased line

Since many plants have a major indicator that signals an alarm via a dedicated line to the local police, it sounds alluring, the leased line to cut. The problem, however, is that the main detector must continuously transmit a signal to the receiving station the police. If this signal is not received, the receiver reports immediate alarm. In addition to the signal line, the status is also monitored with a resistance on the part of the receiver, which prevents the lock-up.

Separation of the telephone line

This could increase the dialer will not perform more alarm call. However, this must be a regular, a potential perpetrator unknown, transmit intervals a status report to a recipient. If the so-called routine callout, assisting measures are initiated depending on the object and guidelines.

There are some ways to add security to a window; the procedures require items available at a hardware store and a center of safety supplies. Some common supplies and tools you have at home will also be necessary.

  1. Apply safety film on the inner side of the window to prevent it is destroyed. Clean the window first spraying with spray glass cleaner. Dry the window with a soft cloth. Placed on the ground the film which has been cut in a hardware at the same dimensions as the window. Remove the protective film role. Hold it with the adhesive side away from you. Place the top edge of the film against the top edge of the window, aligning the left and right sides. Pressed while the cling film along the window. Removes the air bubbles by pushing the edge of a wiper blade against the upper edge of the film and sliding the entire length of the window.
  2. Wireless sensor window does not betray its presence by sending a signal to activate an alarm if the window is disturbed. First open the window and sensor plate screwed to the bottom of the window with wood screws using a Phillips screwdriver. Close the window almost completely. Slide the sensor receiver plate on the ledge of the window so that it aligns with the sensor plate. Upload the window and screw the sensor receiver plate on the ledge of the window with wood screws. Open the battery compartment on the side rear of the wireless transmitter is connected to the receiving sensor plate, insert the batteries and close the lid. Place the wireless transmitter on the wall below the window ledge. Screw the transmitter to the wall. Press the “Sync” button on the wireless transmitter and wireless control panel for the security system’s wireless sync.

Best Security Alarm contacts for windows double hang

Select the best alarm contacts for doors and windows helps to maximize coverage of the safety of all possible points of entry to your home. Contacts consist of triggers that transmit information to a central alarm system. For example, if someone tries to open a window with a contact, the contact feels the same window opening and notifies the alarm that goes off. Several security sources recommend contacts by type of window, as the double-hang.

Recommended Contacts

Sources like Garden State and Cabling Plus Alarm Company, a distributor of electronic security systems, recommends two main types of contacts to double hang windows: recessed or surface. These contacts operate in the same way, both using magnets. Contact, is placed on or in the window frame forms a circuit with the magnet located in the window. When the window is opened, the circuit is broken, the alarm sounding. The assembly of surface mount contacts in window frames, wardrobes while the contacts are mounted inside the frames, you must drill holes to install them. The recessed contacts only work properly with wooden window frames, because you can easily drill into the wood.

Double windows hang

The double-hang have a special feature that affect the installation of the alarm contacts. Unlike most windows, double hang windows can be opened from both ends. For example, a drape window individually containing a single band, which is usually located in the bottom of the window, which slides up and down. The double-hang, moreover, have two sheets, one on top and one at the bottom, both of which are opened. Because of this, double hang windows have more options for potential home invaders, which can open the window in both directions.


The placement of a contact in double hang windows has a major impact on their effectiveness to the type of contact you use, because the recessed surface and work in much the same way. Hang in a window individually; just install the contact at the bottom of the window, placing the magnet in the bottom pane of glass. When the window is opened, the circuit is broken. For a double hang window, you must install contacts on the top and bottom of it, since you can open in any direction. Or, you can place a contact with two magnets, one on each sheet in the center of the window.

Partial Magnets

In his book “Security Now: A Guide to the Security Electronics, “writes Ed Morawskipotential home invaders may be smarter than just security contacts with magnets decoy. For example, if a thief

openyour window while holding a magnet to lure even touch, the magnet may be confused into thinking that contact the circuit remains intact. According Morawski, partial magnets represent the best alternative and the optimum option, the standard contacts and magnets. The magnets used contacts biased only respond to signals from a special type of magnet, so it is impossible to mistake the alarm system with a second magnet lure.

Avoiding Theft at Home

Our home is the place where we feel safe, where we rested and share with family without outside threats. But when it is assaulted, the insecurity and vulnerability take over us and we feel that our privacy was violated. However this complex scenario can be avoided through prevention, taking some useful measures that will help prevent foreign friends come to our home. Here we explain how to prevent burglaries.

Improve safety

In many houses it is easy to break in and steal simply because they lack the basic safety measures . These are typically older facilities that have not been improved by their owners, becoming easy prey for thieves. So it is convenient:

  • Install appropriate solid doors with locks optimized to prevent easy access to housing. It is essential to get used to lock the door when we enter and leave home.
  • Doors should always have sight glass, this way we know who is calling without the need to let in a strange home.
  • Windows should be equally resistant and safe, have a good system to prevent effective seal can be readily opened from the outside.
  • Many thieves break into houses through the sliding doors , so it is essential that a professional install a sliding door with a good sturdy and efficient lock that also has hinged avoid that it can be uninstalled or forced to enter housing.
  • If you move to an apartment or a house with old windows and doors that you can not completely replace at least asesórate or a locksmith professional to find ways to improve safety and make them more resistant.
  • Whenever you leave home or even at night, when you go to sleep, it is advisable to close the windows.
  • We recommend installing burglar alarms when we live in a very large estate, spent too much time away from home, we have many valuables at home or live in a high risk area with many thefts.

In every house, the lighting is essential

  • Those who live at home should have a good lighting system to help make your home a less vulnerable area. Thieves are friends of darkness allowing them to hide and enter homes without being seen, so:
  • We recommend installing light bulbs in the front door of the home and all entries, always lit to keep these vulnerable areas.
  • The areas around the home, like gardens, must also be adequately illuminated. The reflector type lights are a good choice, but if you want to save a system can be installed with motion sensors that turn on when someone passes through the area.
  • When installing your lighting system, let yourself be advised by a professional. Ideally, the lights are located away from any visitor (invited or not), thus cannot disable or break the bulbs.

When we travel

For thieves, the best time to rob a house is when you are sure that no one is in it: during our holiday . Therefore it is important to take some forecasts when planning to leave the house for several days or weeks:

  • Do not make public the fact that you go on vacation. This is something you should know people close, but not everyone, this less vulnerable to the foreign friends how they find you.
  • Make sure before you leave home that you have properly closed all windows, sliding doors and doors of your home. Any distraction can make your home become the perfect target for a robbery.
  • If you are spending a lot of time away from home it is important that your home look inhabited. It is best to install timers on the lights to come on and off at the set time, so it will be more difficult to identify whether or not you are at home.
  • If the trip is prolonged ask a neighbor, friend or relative to collect your mail. There is no better indication that the house is only a mailbox full of letters and bills stacked.
  • If you have an account, activate the alarm before leaving home.
  • Lower the tone of your phone. It may seem an unusual advice, but this way it harder to know that there is nobody at home, it will not have a ringing night and day without anyone attend phone.
  • The blinds are raised and lowered automatically, are also a great alternative to simulate that there is life in the house.
  • Never put the luggage in the car for all to see and in the street. You never know who is watching, and if the whole family with luggage is mounted in the car and goes, it is very clear to the foreign friends that the home has been left alone. This recommendation is especially important for people who live in houses.

Daily prevention measures

Other daily recommendations can help prevent attacks on your home:

  • Never enter a house without looking around, do not know if anyone is following you to get you.
  • Never open the door of your building to strangers who touch the intercom: business mail, hawkers, people gas. Often they are tricks to enter the place and attack the most vulnerable apartment.
  • If you are not expecting anyone, do not open your door to any stranger. Anyone can enter your apartment with the excuse that it is for a survey, for gas or anything else.
  • Use the peephole, was invented just to avoid this kind of thing.
  • When someone rings the doorbell or intercom and indicate that they have a package for that address, you should ask in whose name. If it really is for your house will tell, but the chances are that it is a hoax.
  • If your building or in a nearby building, are remodeling the facade and there is scaffolding installed, it is very important that you increase the safety and well seals all doors and windows. Many thieves take advantage of these structures to climb up the floors and access to households by the gusts. A perfect opportunity to steal at will.
  • Fundamental: never leave the front door of the building open, neither your house. Closes well locked and if once you’re out you remember something you forgot, do not go looking for him and leave the door open in a matter of seconds someone can sneak into your home.

We are all vulnerable

It is important to remember that none of us is safe from being robbed at home, so it is necessary to be proactive, follow these recommendations and invest time and money in our security. This is the best way to avoid a bad time to be attacked in our own home.

9 ways to prevent home burglary

American homes are victims of burglary about every 15 seconds, according to the U.S. Department of Justice. The typical homeowner suffers a loss of nearly $2,000 in stolen goods or property damage.

“With the national economy getting worse, burglary is again becoming a more common crime,” says Charles Sczuroski, a former police officer and now senior trainer for the National Crime Prevention Council.

If you have a high deductible on your homeowners insurance policy, you’ll likely have to pay out of pocket to replace your stuff. But for a small investment, you can make your home less appealing to burglars in the first place.

Prune your shrubs

Bushes, shrubs and trees can offer an intruder places to hide and camouflage signs of a break-in. Trim back any overgrown vegetation so that your home’s windows, porches and doors are visible to neighbors and passersby.

“This doesn’t cost but a few hours of your time, yet it can make a difference in making your property much less attractive to a burglar,” says Officer Mark Buetow of the Milwaukee Police Department.

Draw the blinds

Use shades, drapes and other window treatments to keep potentially tempting household items out of view. Burglary is sometimes a crime of opportunity and “window-shopping” is one way criminals choose potential targets.

Don’t advertise new purchases

Be sure not to draw undue attention to your home by discarding empty boxes at the curb with your trash — a big problem during the holidays.

“By putting out boxes from a new flat-screen television, video game system, a laptop computer or other expensive home electronics at the curb, you’re showing a potential burglar exactly what new and valuable items are now available in your home,” says Buetow.

Get motion sensors

Adequate nighttime illumination is critical, because a dark or poorly lit property makes it easier for a burglar to go about unseen.

“The best deterrent for crime and therefore safety for your home and family is to install motion-sensing security,” says Glenn Dopfel, exterior lighting merchant at Home Depot. “Motion-sensing security lights are … activated when motion is detected and the sudden change from darkness to the bright light will not only startle intruders, but also provide a visual alert to the homeowner and neighbors.”

Set timers indoors

Sczuroskirecommends using timers that are hooked up to indoor lights, as well as radios or televisions. “Setting a timer to switch on about 30 to 45 minutes before it gets dark makes it appear more like someone is really at home, and combined with a radio or TV activating during the day and evening, that impression can be even more convincing.”

“Burglars generally don’t want to be confronted by anyone in a home. They basically want to slip in and out unseen. If they hear sounds of activity, they’ll generally move on,” says Buetow.

Timers can run from about $5 to $40, depending on their sophistication. A basic plug-in unit can turn a light on and off once or twice a day, whereas a wired digital outlet switch can switch lights on at any number of set or random times.

Reinforce entry points

Sixty percent of all burglaries take place at ground floor doors and windows, says Sczuroski, so it makes sense to “harden” these entry points.

All entry doors should be solid wood or steel-wrapped wood-core doors, he says. Hollow-core doors or rickety old wood-panel doors can be kicked in easily and don’t offer much of a deterrent. New solid (slab) doors cost around $100. Installation, of course, will cost extra. However, an experienced home handyman can tackle the job with the help of instructions.

Shield windows near doors

For existing doors with windows, Buetow recommends installing a protective barrier of quarter-inch Plexiglas over any existing glass. Attached properly, it can prevent the burglar from breaking the window and either opening the door’s lock from the inside or getting into the house through the opening.

Install deadbolts

“A deadbolt should be installed on every exterior entry door,” says Melissa Richards, Home Depot’s safety and security merchant, adding that the bolt should have a throw of at least one inch. Insurance companies and locksmiths recommend Grade 1 or Grade 2 American National Standards Institute deadbolt locks on exterior entryways.

The two main types of deadbolts are single and double cylinder locks. A single cylinder deadbolt, about $35, has a keyed opening on one side and a knob that can be turned by hand on the other. A double cylinder deadbolt lock, about $45, is keyed on both sides.

Richards says double cylinder locks should be used on a door with a glass section or one located near a window. “If the glass is broken and someone tries to reach in to open the door, they won’t be able to.”

Consult local building codes before buying new double cylinder deadbolt locks, though. Some communities don’t allow their use due to safety concerns: They can impede a speedy exit from a home in case of fire. And when upgrading any entry door lockset, make sure that the strike plate is properly secured with strong 3-inch screws into the home’s structural framing (studs).

Use common sense

But the best form of protection is to simply lock all your doors and windows whenever you leave your home, Sczuroski emphasizes. “It’s amazing how many people don’t do that, and yet it’s the simplest and best thing anyone can do.”

6 tips to protect your home to prevent theft

While in some cases we cannot avoid them, there are some precautions you can take to try to minimize the risk.

Exterior Doors

Exterior doors should be solid wood or metal to better protect against intruders.

  • Be sure to keep all doors locked or locked at all times. Also the latch or lock bolt should also install a double pallet or similar in all entry doors type.
  • Not all burglaries occur in a vacant home. You could also consider installing a peephole to see who is at the door before opening it.

While in some cases we cannot avoid them, there are some precautions you can take to try to minimize the risk.


  • Whenever you are not at home and overnight windows must remain closed and locked.
  • Consider installing grilles or shutters with locks on all windows to avoid being forced.

Sliding Glass Doors

  • Call a professional locksmith to install closures that ensure the doors to the frame or rail.
  • Adjust the clear spans of rails so that the doors cannot be lifted and removed from the rails.
  • Place a bar resistant metal or wood, such as a metal pipe or a broomstick in the track to prevent the doors from opening.
  • Install latch hinges that slide into the rails to prevent the door from being forced.

Exterior Lighting

  • The lighting, both inside and outside of your home, is one of the best and most economic measures to discourage thieves. The interior lights on give the impression that the house is occupied, while the exterior lights make it harder for a thief to find a place to hide.
  • You should install lighting near porches, all exterior doors, garage and other entry points. Keep all entrances well lit.
  • Reflectors are also a good option for outdoor lighting in your home. You can also choose lights with motion detectors that turn on automatically when you are moving in the area.
  • For safety, install some of the lights out of reach, so that it is not easy to remove or break the bulbs.
  • Aim the lights so that your yard and garden are lit so you can see anyone approaching.

Burglar Alarms

  • Burglar alarm systems can offer many advantages if you live in a remote area or staying away from home for long periods of time. Also, if you live in a high crime area or keep valuable items at home, you should also consider installing a security system. There are a variety of burglar alarms and security systems available.
  • If you install an alarm system ensure that all people living in your home are trained for residential use.

Security while outside your home

  • Make sure your home has the look of an inhabited dwelling at all times. If possible, ask a friend, neighbor or family trust to stay in your home during your absence. Otherwise, arrange for someone remove daily mail and newspapers and turn on the lights.
  • If you are absent for an extended period, consider using timers for your lights so they turn on and off automatically at predetermined times.
