DIY Burglar Alarm Kit: Keeping Your Home Safe and Sound

The home security systems that are considered very important in homes today are burglar alarms. What is exciting about it is that there are DIY (Do It Yourself) kits which provide easy installation for many homeowners. 

However, it is necessary for individuals who are going to use a burglar alarm system to know and understands its basics. Burglar alarms are sensors capable of detecting someone who enters your home. Then these sensors take actions such as making loud piercing noises, call the police, make valuables safe as much as possible, and do other safety measures. 

Generally, these burglar alarms are hard-wired in the walls of your home. This is done to keep it intact preventing it from being removed or disabled. In this manner, the alarm will be easily triggered when tampered. However, the mechanisms which activate or deactivate it vary widely. It could use a more common key and Personal Identification Number (PIN) or even hi-tech fingerprint systems. 

Many people prefer the DIY burglar alarm system kit as they can be less expensive. These systems can be wireless or wired as mentioned earlier. These are capable of setting off audible alarms whenever an intruder moves or breaks into the house.

These systems are available in two types. It can be either a closed or an open circuit. If the alarm has an open circuit design, the alarm works whenever its circuit is closed. Take for example when a window or door is opened, the circuit is completed setting off the alarm. If the alarm has a closed circuit design, the alarm works in opposite ways. When a window or door is opened, the circuit breaks setting off the alarm. 

These burglar alarm systems kits can include (a.) single premise alarm systems which provide specific features such as door alarms, heat or smoke detectors, carbon monoxide alarms, and others (b.) local alarm systems which creates sounds when intrusion takes place (c.)  Telephone dialer alarms which can dial a specified phone number when the alarm is triggered (d.) monitored security systems which are monitored constantly by an alarm company 

Keep in mind that there are existing home security systems rated as more advanced equipment. Some salesman could play on the fear of people for crimes in order to sell them their latest alarm system that is controlled by computers, complete with expert installations that are expensive, and monitoring center open 24-hours on a monthly-basis subscription. As a potential buyer, you should also weigh different options when purchasing DIY alarm systems kits. Sometimes it can be very luxurious yet unnecessary. 



Some people have thought of different ideas to cut down their expenses on purchasing burglar alarms. Their DIY burglar alarm system is made from an alarm box which resembles a real burglar alarm box installed outside their house. This could prevent all hassles and expenses of obtaining the real alarm system. Nevertheless, make sure it actually looks real since you cannot fake experienced burglars. It is a rule to make it a secret or else your efforts would be useless. 

Remember, it is not the features of the burglar alarm system that is making the difference. The secret of using this home security device is keeping the burglars away from your home. The burglar's tendency is to avoid alarm boxes outside your home since they will unlikely expose themselves to great troubles.

Stun Guns

The Stun gun is an effective weapon used to subdue a person by administering an electric shock that disrupts muscle function for a limited amount of time.

While the taser fires projectiles that administer the shock, the stun gun is a handheld weapon that causes a shock in direct contact.

Stun Guns use a temporary high voltage low current electrical charge to stun the body’s muscles and immobilize the recipient.

The recipient feels pain and is momentarily paralyzed. It is also reported that applying the stun gun to more sensitive spots on the body will cause more pain.

Tests show the most effective parts of the body to stun are the upper shoulder, below the rib cage, and the upper hip. The resulting shock causes muscles to twitch uncontrollably, like muscle spasms.

The margin of safety on the use of stun guns depends highly on the overall general health of the person receiving the shock. There is some controversy over the use of the stun guns.

The internal workings are basic and simple, based on either an oscillator, resonant circuit, and set-up transformer or diodecapicator voltage multiplier. This is what causes the continuous, direct, or alternating high-voltage discharge.

They are powered usually on one or two batteries depending on the manufacturer. The power of the output current depends on the recipient resistance, skin type, moisture, clothing, and the battery conditions.

A shock lasting about half a second will cause intense pain and muscle contractions, which startle most people. Two to three seconds will often cause the target to become dazed and drop to the ground, and over three seconds will usually completely disorientate and drop an attacker for several seconds.

Security Cameras You Don't See

Photo: Flickr
Did you know that the malls we shop in every day have security cameras hidden all over the place? And, not necessarily in the individual stores. However, some of the small stores within the malls do have security cameras too, and these in some cases you can see. 

So where are all the security cameras? You would be surprised. I know I would be. But, seriously, you don't think these security "keepers" are actually going to say where the security cameras are. Security cameras are so small now, they can be placed and mounted in many areas, some even in water.

Security cameras can also be disguised to where it is virtually impossible to know where the security cameras are. It amazes me because I had no idea just how many malls have placed so many security cameras within the malls. The bigger malls have even more security cameras. Most of the stores have security cameras; some, of course, you can see, while there are others that are not obvious to you. 

The crime rate is so high-security cameras are on the rise so loss prevention will not affect the cost of the selling of merchandise. Every time some shoplifts and gets away with it, then not only does the store dealers suffer but in a sense consumers suffer the loss as well. Simply put, in order to compensate for theft, the prices for their merchandise would certainly go up.

For this purpose, security cameras are being placed in positions and areas where they will blend in with the surroundings as well as the buildings or lighting fixtures. These security cameras can be placed almost anywhere. Some are small and some may be somewhat bigger in size, however, they will most likely be out of sight. In one mall, at a toy store, a display stuffed teddy bear was where a security camera was actually placed. It seemed that in that one part of the store in the mall, the security cameras that were being used had somewhat of a blind spot and this made it an opportunity for those who were apparently trying to shoplift during the holiday season, get their task accomplished. However, with the security camera in a place where it was, many shoplifters were actually stopped by security at the entrance of the store. This store can't be thankful enough for the use of security cameras.



However, with the use of security cameras, the shoplifting in malls is getting increasingly harder to do. Shoplifting in the malls have gone down a lot, however, smaller stores are still feeling the effects, some just don't have enough security cameras in the right places of the store.

Some store owners with the mall believe its wise to show the security cameras, basically letting shoppers know they are under surveillance. This can be a positive conception, especially to those who feel they can get away with shoplifting.

This being the case, more shoppers will be able to enjoy savings, while the security cameras will hopefully continue to defer those who would like to shoplift and not pay for items.

Basics of a Wireless BURGLAR ALARM System

Safety and convenience – these two factors are the major reasons behind every family’s choice on having a wireless burglar alarm system in their home. Compared to the standard burglar alarm system which is connected using different wires, the wireless alarm utilizes radio waves. Having so, this lessens the many scattered and displayed wires inside your home.

More convenience, as well as savings, is brought by the wireless alarm since you do not need to hire an electrician, also, the equipment can easily be attached on a wall area of your choice as long as you properly adhere to the manual guide included in every package. 

It will be handier that upon installation of your wireless burglar alarm system, you have an adept knowledge of the equipment’s composition.  

Humans have a brain. The brain is considered the control center of the entire body. When some of the humanity’s geniuses invented equipment, they formulated brains for it. The control panel is the brain of a wireless burglar alarm system. Just like human’s brain which sends messages to and receives stimulation from all parts of the body. The control panel is responsible for disseminating signals to the system’s sensors which then creates an “alarm” sound.  

The keypad serves as the heart of your wireless burglar alarm system wherein it is responsible for letting your system function or destabilize. The remote keys are alternative to keypads. Remote keys are normally used in long distance for the system to effectively function. 

Other parts of the wireless burglar alarm system which you should get familiar with are the magnetic contacts, contact sensors, cameras and monitoring devices.  

The magnetic contact is a switch which determines the space between the switch and the magnet. Whenever the space between the switch and the magnet goes beyond its normal measurement and the system has been turned on, an alarm sound is evident. Space heightens when individual attempts to open a door or a window.  

Some wireless burglar alarm system has built-in contact sensors. Motions or excessive heat is being detected by this type of sensors. Contact sensors are commonly used where there are fewer chances for individuals to be present in a certain area in the home or in an establishment. Another supplementary device in the system is the “monitoring service” which detects signals from the control panel. When a burglar enters your home and the system has detected it, an alarm will then manifest. The monitoring service will be the one responsible for calling emergency institutions such as 911, a police station or even the hospital. Thus you are guaranteed that during urgent situations immediate help will come its way. 



Cameras can also be available with this type of alarm system for additional surveillance which may lead to greater protection. The transmission of video information from the cameras will go through a wireless signal which will identify people coming in and out of your place. Thus you will have an easier time to distinguish who your visitors are the culprits.   

There should be no second thoughts when safety is the subject matter. You cannot sacrifice your own as well as your family’s protection over anything else. With sufficient knowledge about the security equipment you have at home, such as the wireless burglar alarm system, you are providing utmost protection that you and your family deserve.

How Does A SECURITY Camera Work?

Basically, a camera set into position with the help of what is known as a video transmitter running to a receiver allows the view from a security camera in a specific place or aimed in a certain direction, such as in a parking lot or door entrance.  The security camera whether it is wireless or not, then makes it possible for the surveillance of anyone or anything through sending visual signals through the lenses back to a security monitor which is connected directly to the system.

In some cases security cameras are remotely operated, while others rely on the actual surveillance of a person sitting in front of the security monitor at all times in a separate area. Another form of security camera, simply records the surveillance and it can be viewed at another point and time. Security cameras all have to have power of some kind in order to work however. 

Additionally security cameras work on frequencies as well as range. Different concepts are taken into consideration when a security camera is installed. Therefore, there are many security cameras on the market today. Some are better than others, while some security cameras are basic and simple, to those security cameras that are very complex.

One of the worst materials a security camera would have to go through would be metal, these types of security cameras are high frequency cameras and are very expensive. Most wireless cameras are limited to four different frequencies while others that must have hidden video lines such as in ceilings or walls can have additional frequencies. The range of reception on security cameras vary.

Security cameras provide the initial perception that the issue is safety, while the second of course is protection, from theft or vandalism of property. The security cameras come in many different designs as well as types. Some security cameras help assist authorities when trying to apprehend suspects in crimes or other acts of violence, or vandalism.

You want to have a good reception especially if the security camera that is in use, is the type that simply records surveillance. As opposed to a security camera that has a person monitoring at all times. In this case you want good reception as well but it doesn't have to be nearly as clear. Security cameras can be as small as a button on a shirt, while others can be the size of an average camcorder. The size of a security camera varies as well.



Price doesn't necessarily mean better, depending on what the security camera will be used for. If the camera is going to be for personal use then one that isn't that expensive will probably do  what you need it for.  Security cameras are made to work for the security of people, places, and things of value, as well as keeping places safe and protected. In some cases security cameras are used to give people the peace of mind of feeling safer than they normally would without one.

Some security cameras work on batteries while others require an alternate power source.
