Security Alarm Systems

Posts Tagged ‘alarms’

Though they protect out home, belongings, and even our lives from outside dangers, many of us don’t understand how burglar alarms work.

In the Good Old Days, how burglar alarms work was simple—the dog barked. But now, how burglar alarms work has become a multi-million dollar science in an industry that is growing rapidly and advancing every day.

We asked Home Security Store’s founder and owner Stacey Winn to help us explain how burglar alarms work.

“You’ll find that there’s a huge variety in alarm systems, from do-it-yourself kits to whole-house wired systems. But most alarms work on the same basic principles, and even the most complex system is based on a pretty basic concept of how burglar alarms work,” says Winn.

How Burglar Alarms Work: Circuit Alarms

The most common first line of defense when it comes to how burglar alarms work is to use the circuit principle. You can have two kinds of circuit alarm: closed circuit or open circuit.

The basic concept is the same: you run an electrical circuit through a door or window. In an open circuit, the electrical current is not completed until the door or window is open, which then triggers the alarm. The only drawback to this system is that all the criminal has to do is cut the wires to prevent the circuit from being completed. In a closed circuit, the current is broken when the door or window is open, triggering the alarm. The all-important control box monitors all the doors and windows and once the circuit is broken, the control box will keep sounding the alarm till someone resets it with a predetermined code.

The control box is often placed in an out of the way place so a criminal can’t easily find it and break it.

The closed-circuit method of how burglar alarms work can be used all around the perimeter of the home. Just create a circuit that will be broken when a criminal tries to enter and you have an alarm system. To make sure the alarm goes off if the window is broken rather than simply slid open; make the glass itself a circuit by running a current through it with a thin foil wire.

Even floor mats can be made into an open circuit alarm. When someone steps on the mat, the circuit is completed and an alarm sounds.

You can surround your home with a closed circuit alarm system that will sound the alarm when an intruder breaks the circuit. But once the criminal is inside, you need a whole different approach to how burglar alarms work.

How Burglar Alarms Work: Basic Motion Detectors

Circuit alarms are highly effective around the outside of your home and business because criminals have to get past the perimeter to get inside. But once they are inside, their movements are too unpredictable to have circuits everywhere inside the house. So then you have to rely on motion detectors.

You run into motion detectors all the time when you are approaching an automatically opening door that uses a radar-based motion detector. A control box above the door sends out radar waves (either microwave or ultrasonic) and then waits for those waves to be reflected back in an irregular pattern, indicating a presence is in the space. For automatic doors, that reflection detection opens the doors, while in an alarm system, it triggers the alarm.

So a motion detector works by constantly monitoring a room for irregular wave patterns. When a room is empty, the radar waves behave one way. But when motion is presented in the room, the pattern changes and the sensor detects the change to trigger the alarm.

How Burglar Alarms Work: More Advanced Motion Sensors

Other than radar-based motion detectors, there are also photo-sensor motion detectors. How burglar alarms work in this case involves beams of light. You aim the beam of light at a light sensor across a passageway in your house. When someone walks through it, the light beam is broken and the sensor triggers the alarm.

More advanced are passive infrared (PIR) motion sensors. These motion detectors see the heat given off by a body. Though the infrared energy tends to fluctuate in any given space, a PIR motion sensor only triggers the alarm when the energy rises rapidly, i.e. when a human, whose average body temperature is 98.6 degrees, enters an otherwise approximately 80-degree room.

If you have a motion sensor alarm system, there is usually delay of a few seconds on the control box to give you a chance to disengage the alarm when you enter the room.

How burglar alarms work has advanced beyond barking dogs and strung-up pots and pans. The science of how burglar alarms work applies measurements of time and space, incorporating the whole room into its security. A good alarm system would combine both circuit and motion sensor alarms, giving you two lines of defense when it comes to how burglar alarms work.

For most people their home is their biggest investment. In 2006 the median price for a home is expected to be $231,000. And of course everyone has insurance on their house. Everyone has insurance on their car as well. But more people have alarms for their car than their home. How does that make any sense?

Most people associate home security alarms with high ticket home security systems, home security alarm systems or home security monitoring that can cost $70 a month or more. I recently heard of a new home security company in New Mexico that is hiring ex police officers only to respond to alarm calls from members because quite frankly the response time from the police department was way to slow. Monitored security systems are effective no question about that. The question is-is there an effective way to protect your house without sending you to the poor house.

Obviously there is a point where cost becomes prohibitive. Each situation is different for sure. Depending on the risk level of the area in which you live many low cost home security devices will do the job just as well as the high priced toys. Remember the objective is to prevent a burglary-keep the intruder from intruding. 

Recently in Colorado Springs a woman was saved from an uncertain fate by an intruder trying to get into her house. She was awakened in the middle of the night by her barking dogs. Now I am not suggesting that everyone get a dog because quite frankly a lot of dogs are not suited for this anyhow. But let’s look at some inexpensive alternatives that do work.

The simplest and least expensive are security alarms activated by opening a window or door. When the alarm is activated a 110 decibel alarm goes off. Other systems using infrared technology detect motion in a room and set off an alarm. Yet another device sets of a realistic barking dog sound when movement is sensed from 30 feet away thru doors and walls. The barking gets louder and more frequent as the intruder approaches.

One more system that has a broader appeal is a motion activated annunciator system that can detect movement from 1000 feet away and “lets you know” if someone is approaching in your driveway, back yard or patio. This system can trigger a floodlight if it senses movement in a designated area. It can monitor up to six zones.

There are many home security alarms available that will do the job effectively without breaking the bank. Why take a chance with such a valuable investment. There are many choices available-one has to be right for your home.

Just as we expect a bevy of safety features in our car, we must take equivalent safety measures in our homes and offices. House alarms warn us of intruders and carbon monoxide detectors alert us if poisonous – and invisible – gas has entered our home. But equally important is the use of properly installed and deliberately placed fire alarms throughout your home. They can be the first line of defense when fire threatens you life or the lives of your family.

Fire alarms are often found as standard equipment in newly built homes. Most states have adopted fire code laws that require fire alarms on every floor of each home. But if you move into an older home you must ensure that all fire alarms are operational and situated in the proper locations. Fire alarms should be mounted on the ceiling of every floor of the house – including the basement. The most important thing to remember is that in a fire situation, seconds count. Give yourself as much time as possible by putting fire alarms throughout your home. While as late as the 1970s it would have cost upwards of $1,000 to outfit a home with fire alarms, today’s homes can be safe guarded for under $100. Modern fire alarms are efficient, technologically advanced, and extremely affordable.

Most fire alarms can be installed by do-it-yourselfers with simple household tools. But if you are unsure about the location or installation process, check with a certified alarm installation technician or contact your local fire department. Remember that more is always better when it comes to protecting the lives of you and your loved ones; so don’t cut corners when it comes to purchasing the best fire alarms.

Some fire alarms can be integrated straight into your central alarm system. So in addition to alerting authorities if you should have a break-in, it will notify fire personnel should your fire alarms sound. This can be especially helpful if you are away from home on a frequent basis; you will rest assured that your home is always being protected.

In addition to fire alarms, be sure that you and your family have a fire plan that you practice several times a year. This should include an exit strategy for every person in the house as well as a meeting location at a safe distance outside the home.

Product Description
ISO 12239:2003 specifies requirements, test methods, performance criteria, and manufacturer’s instructions for smoke alarms (including those with optional features) that operate using scattered light, transmitted light, or ionization, and are intended for household or similar residential applications. Smoke alarms with special characteristics and developed for specific risks and devises intended for incorporation in systems using separate control and indicating equipment are not covered by ISO 12239:2003. For the testing of other types of smoke alarms, or smoke alarms working on different principles, this document should be used only for guidance.

People spend a lot of time and money on buying their ideal house. Once you have purchased your dream house and decorated it, it is time to think of protecting it. We often tend to overlook home security systems, until a burglary happens. It is safer to install home alarms and be prepared for any situation. The most important aspect of a home security system is the home alarm. Home alarms make sure that you get necessary help when you are in trouble. This makes its essential to get home alarms from the best home alarm company in the market.

While selecting a home alarm, make sure you choose a house security alarm system for the entire house. No part of your house should be vulnerable enough to be attacked or intruded by burglars. The home alarm company should be able to provide you with separate alarms for the individual doors and windows. You should carefully decide which doors are windows are more prone for attacks and accordingly install the home alarms. The more the number of doors with home alarms, the greater will be the cost of installation. Try to avail special package offers to cut down on the price.

It is essential to have a live monitoring system along with your home alarm. Home monitoring systems never let you down. These always keep you updated on the on-goings in your house. Home monitoring systems have the capability of informing police or fire services if needed. You have to conduct a market survey to zero in on the best home alarm company.

Home alarms are easy to install and can be installed by the user too. If you are unable to place it, you can get in touch with the service providers or local contractors. While setting up the home alarm, you have to select the most appropriate place for the alarm control box. You can set it up on your back door, front door, on any windows or anywhere else. Select a place where you can easily turn off the alarm when you are at home.

After choosing the place, you have to program a code for your home alarm. This code will enable you to turn on and turn off the home alarm when required. If you have motion detectors as a part of your home security system, the home alarm will be triggered the moment it senses movement in the house. A home alarm company provides the facility of motion detectors as a backup plan if a burglar manages to get past the alarm.

You can also opt for outdoor home alarms. A home alarm company programs the outdoor home alarm in such a way that it activates the floodlights as soon as movement is detected outside the house. It is a general idea that home alarms are expensive and cannot be afforded by all. Sometimes people have wrong assumptions because they do not investigate about the actual costs. This mistake is not to be made with a home alarm. There are home alarm company that provides alarms for apartments and houses at a reasonable rate.

Securing your home can be one of the most expensive and time consuming endeavors you will undertake if you let it get out of control. Every company has hundreds of solutions that will meet your needs, and they will try to sell you them all under the guise that the more security systems you have in place the better your protection will be. The truth is this will just provide you with a great deal of hassle and lull you into a false sense of security. With all of the different devices available you need an easy way to sort through them to find the one that is right for you. Below you will find a list of the basic types of driveway security alarms and how they work:

Wired Sensors – This category covers half of the devices available on the market. You can buy any of the subsets of sensors as a wired sensor, which you should do if you will need to be running a long distance or through a material that will dampen wireless signals. These are often slightly more expensive than their wireless counterparts, but they are much more reliable.

Wireless Sensors – The other half of devices fall under this category. They are usually less expensive to install and maintain, but they can be unreliable when their signals are interfered with by inclement weather. They are more versatile than their wired counterparts because you can move them if the need arises.

Motion Sensors – The basic security device, motion sensors use laser or infrared beam to detect movement. When something breaks the beam their transmitter sends a single to a remote receiver, which emits an alarm sound so that people know that they have been triggered. These devices make a great catch all as they are capable of detecting car, people and animal movements. The problem is that they cannot differentiate between the different types which can lead to a lot of false alarms.

Magnetic Sensors – Magnetic sensors are driveway security alarms that detect the movement of large quantities of metal. They are specifically designed to monitor cars, and are incapable of detecting people or animals unless they are covered in metal. This makes them the ideal solution for people who are trying to monitor when someone is pulling up their long drive, or when a customer is entering a location. Many, like the Dakota Alert Driveway Monitor, are buried underground to protect them from vandalism and the elements. This makes them a great choice for people in high stress areas.

With this information you should be able to choose the security system that fits your needs the best. Remember, however, that any security system is only effective as the people who are using. If you think that having a system in place will protect you from burglars, vandals, and murderers then buying one will only open you up to greater exposure to the threat of becoming a victim of one of these criminals.

When you listen to the news there are many times when you will hear of a new robbery that has been committed. For the ordinary person this can be very alarming news, especially if your neighborhood has been a victim to robberies. To help the homeowner cope with these types of disturbances there are various home burglar alarms that you can install.

These home burglar alarms can range from the simple and inexpensive to the more complicated and expensive burglar alarms. To investigate the various home burglar alarms you can visit the many security stores in your area and see what they have that will fit your budget. There are a few types of home burglar alarms that you can look into.

One type that you can see is that of driveway alarms. These alarms add an extra layer of protection by informing you if any one is found to be coming to your home via the driveway or the yard. The other type of home burglar alarm that we are most commonly acquainted with is that of home security cameras. These cameras can be used to monitor the exterior of your home or various places where it is somewhat difficult to see.

You can also use motion sensor home burglar alarms. These burglar alarms function by detecting the heat motion that is caused when someone or an animal passes through your property. You can set the height and width of detection parameters. These types of home burglar alarms can feature a lighting system that activates when there is activity in your property. When the motion detector senses body heat somewhere within its field of sensor range it activates and your property will be lit up.

There are home burglar alarms that can be set to protect your home from being broken into. With these burglar alarms the trigger is the illegal entry into home either by the windows or your doors. Some of these home burglar alarms are connected to the police and the security company that installed the home burglar alarm.

This means that when someone tries to come into your home by force the police will be notified and they will have time to respond. Hopefully this will also allow them to catch the robbers as well. As you see there are many different home burglar alarms that you can have installed in your home.

Since there is a wide choice of home burglar alarms you have the right to expect buying an excellent alarm system will bring to your home a level of comfort and security that you want. Therefore you should look into the matter of home burglar alarms very carefully and buy only the best.

When people want their homes, offices or businesses be protected from intruders, they install security alarm systems. With the rampant crimes nowadays, it is best to be safe than be sorry later. With the different types of security alarm systems available in the market today, it is quite difficult to select which one to use. But usually, it boils down to two major choices: either you go with a hardwired system or go with wirefree burglar alarms. More and more people nowadays are going wirefree, since its less of a hassle.

Based on your security needs, you can determine if you want a hardwired type of burglar alarms or go for the wirefree burglar alarms. It is also subject to the availability of the said system as well as the cost considerations of the client. If you are working on a new building, or having a major renovation wherein the walls and flooring might be changed, it is recommended that you go for a hardwired system. This is cheaper, and one can run the wires or cables underneath the floor or the walling system so that it will be hidden from view.

If you are working with an existing room, having a hardwired system might destroy the interior design of the room, or it might be difficult to run the wires, so a wirefree burglar alarm system is recommended. Though wirefree burglar alarms are more expensive (usually 25% to 40% more than the hardwired kind), they are easier to install and they can be discreetly placed. This can also save time, energy and money if used in the right situation. But more and more people, regardless of the existing situation go for wirefree systems nowadays.

In the past, wirefree burglar alarms are considered inferior to their hardwired counterparts. Most complain that they didn’t work properly, or some amount of signal loss was observed, especially if there are obstructions between the components, such as a solid wall.

Old wireless systems also experience signal loss if the components were to far from each other. Of course, these might have led to break-ins that go undetected. This was the problem in the past. But now, with new technology, wirefree burglar alarms are functioning much better than before.

New wirefree alarm systems have innovated and are now more efficient and more suited to modern needs. Whatever the area or the type of sophistication that the company requires, there is a suitable wirefree burglar alarm system for this.

So, If you are looking for good alarm system, you might be considering to get a wirefree burglar alarm. Not only is it efficient, it is also hassle-free in installation as well in maintenance. Though it might be more expensive than a hardwired system, it gives you value for your money since you don’t have to spend much time and effort in installing them. It’s as simple as putting one up and letting it work. There are a lot of benefits when using this system.

Installation of smoke alarm is an important undertaking in order to alert the danger of fire in homes. The wi- safe range of smoke alarm helps a person wake up when a smoke or carbon monoxide alarm is triggered anywhere in the house. It has the capability to convert into a torch to aid escape. The loud alarm indicator and high quality ionisation sensor make this life saving device a complete success.

Once you decide to buy a security alarm system, you will realize that there are an overwhelming number of companies which manufacture them. Even though this will make it difficult for you to make a choice, never give in and steer clear of sales people who are determined to make a sale. Always do your own research before stepping into a store so that you do not end up regretting the purchase as these security alarms can be quite expensive.

The basic benefits of a security alarm are obvious- they help you to avoid theft and keep your property where it belongs, that is, with you. In other words, unwelcome intruders are kept away as your house is protected as the alarm will notify you whenever something out of the ordinary takes place. When an alarm is installed, the company also puts up a sign outside which advertises the fact that your house is secure and under constant surveillance. This will make burglars think twice before taking any chances. However, if they do, they will not get away without getting arrested as these systems have excellent success rates.

The entire packaging includes several components, namely, sensors, keypads, a siren and a control panel. Apart from that, the individual is also given direct access to the company which is monitoring his house. Every door and window is attached with a sensor which alerts the authorities if an unwelcome stranger is stepping onto your property. Certain sensors are sensitive to such activities which result in glass being broken. The alarm is immediately triggered and the company is informed. The above mentioned siren is attached in certain rooms. The noise is shrill and is sure to startle the intruder into leaving your house. A security alarm system is definitely something everybody should invest in. Apart from the safety factor, it also adds to the overall value of the property which will make it easier for you to sell it in the future. Insurance companies are more flexible with matters related to homes which have strong security systems. A security alarm will allow you to relax if you live alone or if you are out of town and unsure about your neighborhood.

When you are looking to buy a security alarm, make sure that you contact a well-known and reputed company. This is because these companies can be trusted and their technology can be depended on. If you choose to rely on local companies, you will be fooled into buying an expensive system which will not live up to its cost and you will end up wasting all that money.

A video intercom is a device which adds to the above mentioned benefits of a security alarm. A buzzer is attached onto the video intercom which allows the individual to see the individual before giving him permission to enter your property. Even though it becomes difficult to ascertain who is bad news and who is not, it is always recommended to make use of some common sense as well.
