Home Security Devices for Your Home Security System


When you are selecting any home security device that forms a necessary part of the home security system you are building to protect your family and home, you should first do the needed preliminary work. You will need to identify what home security devices you require for the level of protection you want. Second, you need to know how many of each type of home security equipment will be necessary. Third, you need to be clear on any budget limitations. Quite naturally, the amount you are able to spend will affect the type of home security devices you will be using, from very simple to highly sophisticated. Another consideration is installation. Will you be installing the system yourself or having it done professionally? This can affect both the costs and type of home security device you decide to use.

Home Security Devices

Simple vibration detectors for your windows and door jam magnet detectors are basic home security devices that you will most likely install on all windows and entry doors. These may be wired or wireless detectors depending on how your full home security system is structured. Systems may also include external lighting controlled by motion detectors while inside some homes will use motion detectors for monitoring some rooms. Motion detectors can be adjusted to ignore pets or small animals but still detect any people entering a protected area.

Passive infrared detectors may be used to detect changes in ambient temperatures and then trigger an alarm when there is a significant change. Active infrared detectors use an infrared beam passing from a transmitter to a receiver which triggers when the beam is interrupted. While a relatively large area can be covered this way, the source of the beam can often be detected and it can be possible to work around this type of detector.

Another home security device is the pressure mat which triggers when it is stepped on. A variety of wired and wireless surveillance systems use either indoor or outdoor security cameras or both. Wired and wireless security cameras can be full color, black and white, low light or even use infrared for coverage in extremely dark conditions. Wireless security cameras which have integrated motion detectors can save both battery life and storage space for recordings since they only activate and transmit when motion is detected.

Another device you might want is a dialer system for alerting a call center in the event of a break-in, during medical emergency situation or even in case of a fire. This home security device allows for an automated system that can essentially monitor your home and report possible problems even when you are away so this is a piece of equipment that you may want to consider both for your safety when you are home and for your property's security when you are away.

Wireless Surveillance Systems and Home Security


There are some basic differences among home security systems and what are usually referred to as wired or wireless surveillance systems. While wireless surveillance cameras are often a part of a full home security system, their function is slightly different. Many businesses, banks, ATMs and even public locations now have surveillance cameras installed. In some cases they are simply recorded and temporarily stored, only being looked at if there is a question of criminal activity. In other cases they are actively monitored by security personnel.

Wireless Surveillance Systems

In the case of home security systems using surveillance cameras, there is often a combination of functions. They be used by residents to verify who is entering the premises or who is at the door. They may also be used for checking that all is well in various rooms inside the home. They can also be used to monitor and record activities within the home (such as a nanny or babysitter) or outside such as a handyman or caretaker. And, naturally, they can be used to record any breakins or other criminal activity.

The major advantages to going with wireless surveillance systems have to do with the ease of concealment and installation, the ability to expand a system into a full home security system, and being able to move your equipment easily. The biggest disadvantage is the need to replace batteries on a regular basis. No wireless surveillance system is going to do you any good if the batteries are dead. Wireless also means that each device must be able to transmit to a receiver through any intervening obstacles such as walls. While most transmitters should have a range of 200 to 300 feet, the range is affected by obstacles and may drop as batteries weaken.

There are different types of wireless surveillance cameras that you can choose from. Older models generally provided black and white images but newer (and sometimes more expensive) cameras provide color images. You do however need to consider the light levels your cameras will need to deal with - generally the very low lux level cameras will be black and white and if you need to cover very dark areas you will probably want infrared capability. You may several different models to cover each of your specific needs. As part of a full wireless surveillance system, each door to the outside and the approaches to the house should be covered by cameras. An ideal setup would provide full coverage of the perimeter of the house. As noted above, you may also want to have surveillance cameras within the house.

The other main components to a wireless surveillance system include door and window alarms and may also include motion detectors connected to either alarms or lights. Active infrared alarms can be used to monitor interior rooms, though the need for line-of-sight transmission and reception can be inconvenient and some such alarms may generate a visible beam which can then be avoided.

A solid, careful evaluation of your security needs will help a great deal in doing the planning for your own wired or wireless surveillance system. You will need to decide if you want to have your system professionally installed or whether you have the skills and time to handle it yourself. It may also depend on whether you are planning a standalone system or want to have a third-party monitored system. Whichever way you go, any type of home security system will enhance your safety and act as a deterrent.

Do It Yourself Home Security Systems



In today's electronic age it is becoming simple for the handyman to work with do it yourself home security systems. Home security equipment is now widely available from a variety of sources. Through the use of wireless technology, plug-and-play home security cameras and digital video recorders, a person can actually set up a do it yourself home security system in their home or business in less than an hour. Of course, more complex systems which can include multiple door and window sensors may take a bit longer.


But - before you run out thinking you know what you are doing and start buying stuff for a weekend do it yourself home security project, you actually need to survey your house and property to determine your real needs. Particularly with security cameras you want to make sure that the placement allows full coverage of critical areas. With door and window sensors you will want to insure you can cover the entire area. With devices such as cameras, the use of motion detectors can save space on your image storage device as well as reduce playback time following an incident.

Once you have determined where you believe cameras and other devices may be needed, visit the online sites of companies to determine the types of do it yourself home security devices that are available. You may find that by using wide-angle lenses you can reduce the number of cameras needed for close-up surveillance. Additionally, for faster identification of potential problems, longer lenses can be placed for views of areas further away from the building. Where possible it may be better to avoid using panning cameras since they could leave areas uncovered at times. And they also have more parts that can potentially fail.

For most people the best solution is probably to purchase an expandable diy home security system with the basics you want for your project. Additional components to expand the capabilities of any such security system must be easily available, so you should look for a system that uses established standards and can be connected to a variety of brands of additional equipment. Since it is unlikely that a kit home security system has exactly what you'll need for your home, be sure to get any additional pieces you may need.

Have Everything Handy Before You Start Your Project

When you think you are ready to begin your do it yourself home security project, double check that everything you need is on hand. There is nothing worse than being on the roof installing a camera and finding out you are short of cable connectors. You will have to climb back down the ladder, head to the store and, if it is open, buy what you need and then head back up the ladder. It is better to inventory your equipment and supplies at the beginning of the project than have to stop in the middle.

Make sure you have a checklist of exactly what needs to be installed, where, and in what order. If you decided on a wired system, better make sure you have extra wire and connectors. Be systematic and work through your checklist. Test each step as you finish before you check it off. If you are installing cameras, then, unless you have access to a battery operated television with which to view the images from the camera, you will need help lining up the cameras used for your do it yourself home security system. While you adjust the views from the cameras, have your helper watch the video screen to make sure the image received catches the area needed and that the images are in focus. Motion sensors may also require adjustment. Having every stray cat or squirrel triggering your motion sensors and turning on the outside lights gets old fast.

When you've completed your do it yourself home security system, make sure to run a series of tests on all the components before you congratulate yourself. Once you've verified that everything is working the way it should, you can relax with the assurance that your home security system is on the job protecting your family and your property.

A Wireless Home Security Alarm System can be Installed Easily


Depending on a house's style and size, a home security alarm system could be quickly installed using the older wired security devices. However, in many homes using a wireless home security alarm system will make installation much simpler. Installation of a wired home security system requires drilling holes and pulling wires through walls or into basement and attic areas. That can be difficult, time consuming and dirty work. Typically, the installation of this type of system is better left to the professional while a wireless home security alarm system can normally be done by the homeowner with little effort.

Wireless Home Security Alarm System

Unlike wired systems, the components of a wireless home security alarm system can be easily moved from one location to another to provide protection where it is needed without messing with wiring. Naturally, adding on to this type of system is also easy although every receiver will have limitations on how many devices it can handle effectively. Staying under the maximum number of supported devices will insure that your security system functions properly.

Every device which is connected to your wireless home security alarm system has a built in transmitter which sends a wireless signal to the receiver. In the case of the less expensive systems, the receiver will simply sound the alarm when a device is activated. More costly setups will not only sound the alarm, but also indicate which device caused it to activate. This can be a most helpful feature when you're troubleshooting a false alarm or want to quickly identify where the potential danger is.

Wireless Systems Have Some Limitations

While the ease of installation makes a wireless home security alarm system an attractive option, there are some disadvantages. Since the transmitters used in wireless devices operate on batteries, you need to monitor the batteries charge and they will need to be replaced regularly. With cameras, choosing motion sensor cameras can save power when the cameras are not operating, but the batteries will still drain periodically and need to be changed. One reason why close monitoring of battery status is important is because as the battery weakens, the strength of the transmitted signal falls and it may not trigger the receiver or could lead to a false alarm.

The construction of your home can also limit the distance a signal travels. While most wireless home security alarm system devices will send out a signal reaching 200 to 300 feet, wood, brick and metal walls can weaken the signal strength substantially. With high quality, thick walls - particularly if there is much intervening metal, signal strength could be cut in half, or more. The unit may still function properly, but if the signal cannot reach the receiver, then obviously the alarm is not going to work. The location of the receiving unit should generally be in a location which minimizes the distances to all the transmitters. 

Testing can help you determine if there are any potential problems with signal loss. Be sure to continue your testing through at least the first set of batteries so that you can catch any signal loss that occurs as battery strength diminishes.

Outdoor Security Cameras - More than Amazing


There come times in your life when you run into the kind of gizmo that's so fascinating that it hardly matters if you actually need it or not. The sort of thing you want to just sit and be awed at it – sort of like a high tech lava lamp. One such gadget is the outdoor security camera. It utilizes technology that would give Mr. Spock a headache. And, depending on your circumstances (see your tax advisor), you might even be able to write off your costs for an outdoor security camera.

Outdoor Security Cameras


Why Are They So Cool

They have infra red night vision. Yes, yes - they can see in the dark. So now, with your new outdoor security camera, you see what goes bump in the dark and where it's bumping. You can check out the wildlife in your back yard. Hmmm. You can also check out the wild life over there in the neighbor's yard (just kidding, you wouldn't really do that would you?). You can (and should) get weatherproof outdoor security cameras, armored outdoor security cameras (talk about protecting your investment!) and even outdoor security cameras for under $100 (US). You can choose black and white outdoor security cameras or color cameras (this refers to the images you see, not the color of the actual camera itself).

And, did I mention that they have infra red night vision?

Fun Accessories


Sadly, the camera can't do it all. It tends to be just the star of an ensemble piece. You need brackets, instructions, wires and some kind of monitor. Most security cameras are hooked up to internet services. Don't just buy the first pretty outdoor security camera that winks at you. You need to check out what specifications it needs in order to operate. You also need to consider whether you want just a monitor or a recording device also. And whether you want a wired or wireless system.

Any potential security camera company you think of doing business with has to be able to answer a few basic questions before you lay any money down:

Who installs it?
Who fixes it?
What refund policies do you have?
What warranties do you offer?
Are there any lenses that fit onto this camera?

These questions should cover the situation for a system that doesn't include an off-site monitoring service. A fully monitored system is a different beast and requires a lot more thought and analysis before you pick a company to go with.

In Conclusion

Outdoor security cameras may be a little expensive but they are very cool. If you don't necessarily really need one, but do need a good excuse to buy one, check with your homeowner's insurance policy to see if you get any discount by installing one. Check also with your state tax laws – sometimes security cameras qualify for home improvement tax refunds. And don't forget to check with your tax advisor to see if it could be written off as a business expense.

Simple Home Security Tips To Help Protect Your Family And Home


Home security and safety has become an increasingly prevalent concern for neighborhoods in many cities. Even in smaller communities where crime is a lesser problem, following a few home security tips not only can make your home safer but can add to your peace of mind. Certainly the use of alarm systems, video cameras and other wireless surveillance systems can make you feel more secure and loud alarms will normally scare off the vast majority of burglars. However, also using these simple home security tips a family can follow in addition to other steps will help protect them and their property.

Simple Home Security Tips


The first step is to check every point of entry. All exterior doors should be made of solid wood or metal so check them to make sure none are hollow. If they are, replace them with solid wood or even metal core doors. Every door should have a deadbolt. Do not rely on a door lock without a deadbolt. If you have a home with any sliding glass doors, be aware that you can not really trust the locks on most of them. Locking pins can help and always use a wood or steel pole that fits tightly in the track so the door will not slide. If you are in an isolated area without neighbors close by, you may want to consider replacing glass doors with something that can't be broken to gain entry.

Windows are also potential entry points and in an isolated area can carry the same risks as glass doors. Still, most burglars are reluctant to make much noise. Check to make sure that all windows close properly and can be locked. One often overlooked home security tip is to train everyone to always make sure doors and windows are secured when leaving and at night. People forget and burglars take advantage of that.

Walk around your home's exterior and look for what amounts to an invitation to burglars. Many home security experts consider it safer to avoid trees or shrubs in front of windows. This is especially true in areas not visible by passers-by such as the backyard. Someone can hide behind the foliage while working on compromising a window's lock. One home security tip is to plant dense thorny shrubs close to the wall in front of windows and keep them trimmed to below the window ledge. Few burglars will put up with the thorns. Next, you should eliminate dark areas around the home. You can install small lights by shrubs and also use motion activated lighting.

Think About How a Burglar Views Your Home

Most burglars are not into hard work. They're looking for the easiest entry with the biggest payoff. They normally want to get in and out without attracting any attention or wasting any time in an exposed position. If you have an alarm system installed (and maybe even if you don't), a sign in the yard and signs on the windows warning of the security system, will often cause them to move on hoping for easier pickings.

Other home security tips include keeping the curtains drawn at night, especially if you're not at home, and keeping valuables out of sight. High-cost, high-demand electronics which are visible from the outside are a lure to burglars. Check the sightlines from outside and where possible locate expensive, portable items where they can't be seen. If a burglar can't see your valuables, he may be unwilling to risk getting caught. Invest in a simple timer to connect to a light and perhaps a radio when you'll be out of the house. A dark house at an hour when most people are still awake can be an invitation to a break in.

By themselves, these home security tips can greatly reduce your vulnerability. The use of home alarms, wireless surveillance systems, outdoor security cameras can also all contribute to ensuring the safety of your family and your property. An aware, organized neighborhood where everyone knows and looks out for each other and their property is one of the strongest sources of security. It does take some time, effort and commitment, but it can make for a safe, pleasant neighborhood with a high quality of life for all the residents.

There are many components that make up a home security system.  A good system will have both indoor and outdoor alarms. Some systems are silent and alarm only the police, emergency numbers or monitoring service, while some emit a loud piercing alarm, and some will do both. Window and door alarms, motion detectors, security cameras, security lights, etc.  Some people also have a protective safe or vault to store their important documents and valuables.  However, it's really very easy to get carried away and go overboard on home security.  Take into account when picking out your security system that while it should offer maximum security for your family that it should not interfere to much with their routines during the day or night.  

Basic indoor alarm systems are a excellent deterrent for any would be intruder and is also easily adaptable to any family.  You may consider taking additional measures to protect your home if you're usually away.  Installing plexiglass window panes to windows or doors that are low to the ground is a good way to keep a possible intruder from entering your home through a window.  Security lights and motion detector alarms also work well by tricking burglars into thinking that you're in the house.

If you happen to currently have a home security system, it is necessary to maintain proper care of your equipment.  Have your system tested every few months to check if it's operating properly.  Replace low batteries, burned out bulbs and clean dust from the sensors.  Invest in long lasting batteries and long life light bulbs if you have trouble remembering to test your security equipment.

Besides giving you the peace of mind that your home is protected, homeowners insurance in some cases are lowered by as much as 20%.  Check with your insurance carrier to see if this option is offered to you.

Security systems for home use that are available on the market today in many cases can be purchased at a reliable online website.  You can often get free shipping and discounts that are not available in retail stores. Get yourself a home security system and give yourself the peace of mind that you're safe and protected in your own home.

Working Style of Today’s Sophisticated Burglars Alarm


Lots of business and stores are today fitted with burglar alarms; furthermore, they are flattering progressively more ordinary in private residences also. In case, if you have not yet made a purchase of a scheme to secure your home, then you must understand that there are wide selection of options. You can avail these systems from the model that can be handled by the kids to that of the complicated ones that needs the installation by the professionals. However, majority of such alarm schemes are constructed on the same concepts.


Here, in this piece of article, you can have a look regarding the concepts and you can examine some particular model.  You can view that the handpicked alarm models are the simplest one.

Breaching the circuit

Excluding your family dog, your most fundamental burglar-alarm is considered to be the uncomplicated electric circuit that is constructed into the doorway. In any kind of circuit, whether it forms to be the computer or flashlight, there is only the flow of electricity when a path is given between 2 points of opposed charge. Unlock or lock the circuit for turning on & off of the electricity.

For opening or winding up the flashlight circuit, it is enough if you simply fling a switch. The switch of the burglar alarm becomes aware of the performance of the interruption – opening a window or door, for instance. These kinds of alarms can be split into 2 groups:
  1. Closed-circuit method: In this method, electric-circuit is got closed at the time when your door is put down the lid. This implies that until the door remains shut, the electricity flow from the circuit’s one corner to that of the other. However, if anybody unlocks the entrance, it opens the circuit and the flow of electricity is stopped. This sets off an alarm.
  2. Open-circuit method: In this organization, opening of the door completes the circuit and the electricity starts flowing. In this scheme, when there is completion in the circuit, the alarm gets activated.
There are numerous modes for constructing this kind of circuit in the entrance. It is better to construct closed circuit than the open circuit for the reason that a robber can switch off your open circuit just by cutting the wire connections.
A magnetic feeler is considered to be a closed-circuit that holds a few uncomplicated mechanisms. To get the fundamental design, you call for:
  • A battery to power the circuit
  • A metal that is usually, driven by spring, for constructing the entrance border
  • A magnet fixed on the entrance and connected with the button
  • A buzzer that is separately-powered with the relay-driven button.
If the door gets locked, the metal drags the metal button and gets it closed and the circuit is concluded. Relay’s electromagnet is powered with current and your buzzer circuit remains open. When the magnet is moved by unlocking the entrance, the spring breaks the button again into the unlocked position. This disconnects the current and winds the relay, noising the alarm.

It is possible for you to construct this kind of scheme on your window. If the robber tries to push the window, the magnet gets beyond the channel of the switch and your buzzer is set in motion.

Another model of burglar alarm utilizes small knob as a switch. The knob is fixed on the door’s frame and if the door is locked, the door drives it in and if someone unlocks the door, the knob is released. This alters your circuit and results in sounding of alarm.

Just with the help of buzzer and battery, these models create a fairly defective security scheme. Simply, the burglar requires locking the entrance once again to switch off the buzzer. For this reason lots of modern alarms for burglars are incorporated with another device inside the circuit known as control box.

Becoming Aware of Motion

For giving protection to your home’s perimeter, circuit alarms renders vital role, however, they do not look too smart inside a construction. The reason for this is that the actions of the burglar are highly random – you cannot say correctly the place where they enter and what will be done by them. The particular activate is not highly effective. For detecting the burglar who stays already inside the home we need motion detector instrument.

These days fundamental motion-detectors are widely found, for instance they can be seen in the automatic doors mostly. You can avail various kinds of detectors.

Example for motion-detector based on radar is the automatic gate opener. The explosion of microwave radio energy is sent out by the box that is placed at the top of the door and then hangs around for the bounce back of the reflected energy. In case, if nobody is there near the door, then the radio energy bounces in the equivalent way. However, if someone enters the region, the model of reflection is disturbed. At the happening of this, the sensor forwards the indication and the gate gets opened. In the case of the security system, obviously, the sensor forwards the alarm signal at the time when the way of reflection is troubled.
