How Does A Motion Detector Work?

An alarm system is a great way to provide extra protection for your home. There are plenty of options available for you to ensure your home’s safety. So don’t take chances. Protect your family with a home security system that will safeguard your most precious valuables, and the people you love.

What are they?

Motion detectors spot the movement in areas covered by the security sensors. Motion detectors transmit high frequency radio wave signals. They give a warning that someone is entering into your home.

Different kinds of motion detectors & how they work:

Infrared Sensors:

Motion detectors use infrared light to detect heat changes, i.e. when a person moves across this light it detects them with the help of the infrared sensors. If a person moves in the range of the motion sensors, the alarm is activated. Infrared sensors are cheaper than microwave sensors and ultrasonic sensors. Infrared sensors are generally smaller and very reliable.

Vibration Sensors:

It detects a person through vibration. Many car alarms have this feature to alert the owner that something has bumped into their car.

Photoelectric Sensors:

Some motion detection systems use lasers and photoelectric beams. The laser is shot across to the other side of the room or doorway. If the laser is interrupted the unit’s alarm signal is activated.

Ultrasonic sensors :

They use a frequency around 30kHz. The transmitter bounces the waves of walls, furniture, windows and ceilings and when the room has stabilized, the alarm is armed.

Acoustic Sensors:

They can detect the energy produced by any kind of sound, including breaking glass. In the case of breaking glass from window intrusions, the pattern of the sound emitted is detected.

Are Security Cameras Really Necessary?

Security is very serious and for many having security cameras are a great option. For most of us, we’re away from the home and so we wonder what is going on, and also what if someone breaks in while you are away.

Not having a security system now a days is like playing Russian Roulette, and it’s only a matter of time before something might happen, and then you will be left holding the bag about your safety. I hope nothing never happens to you, but it’s a true fact that for the most part, crime is on the rise, and with recessions and hard times crime really goes up.

With the internet, you can go wireless and see what is going on from your laptop, or even your cell phone. You can be contacted via text or call when the alarm has gone off, and when some turns it off, so you can know when a family member has made it home. How convenient is it for you to know your family made it home, and if you’re away and you forget to set the alarm you can turn it on or off, amazing.

Most people look at the cost of the alarm system and say it’s too much. If that is the case you need to go through your house and put a price tag on your family, your pets and your valuables, and then I guess you will have your answer if it’s worth it or not. I personally think my family is priceless, and there is no amount of money I would spend to protect them. Security is no longer a fad or a gizmo, it’s a necessity of life for you and your family.

Home Alarms

A home alarm can be a great tool to help add an extra layer of protection to your household. A home alarm can be simple or complex, but is quite reasonably priced. The most common types of easy to use and install home alarms are explained below.

Motion Alarms
Motion alarms come a variety of sizes and styles; however a good option for any home is the Mace Motion Alert. This alarm mounts quickly and easily near any entry point in the home. There is no need to hard wire the device, as it is battery powered. Equipped with a keypad to program a personal entry code, this alarm can sound as a high pitched alarm, or as a two-tone entry chime. You and your family will be alerted quickly when anyone enters the home via door, window, or cellar hatchway.

Voice Alarms
Voice alarm systems feature wireless passive infra-red motion detectors (PIR) that transmit signals to a special base system. Users record their own warnings on the base system and for each zone that is monitored within the home. For example, if zone one in your home is your back door, your recorded alert could be “someone approaching back door” when motion is detected in that area. These recorded alerts can be modified at any time, and the motion sensors can be moved as needed. The system works in all weather conditions, and signals can be transmitted up to three hundred feet through walls, or one thousand feet in open space.
Door Alarms

Door alarms are a very simple, but very effective alert tool that no home should be without. While there are a few variations of this alarm, the premise remains the same: to notify occupants when someone approaches, touches, or attempts to open a door. Door alarms are great for travel and require no installation. In most cases these devices cost less than fifteen dollars, and are worth every penny!

Keeping Your Family Safe on a Budget

Everybody worries about the security of their homes and families. The question is: how can you make your home safe without turning it into Fort Knox? The sad fact is that, if someone is resolute to get into your house, they can and will. Ten years ago, my home was ‘safe’, but I was conned into opening the door and I let my attackers in. No home security system can safeguard against circumstances like that.

Burglars look for homes that look vulnerable. Most criminals are opportunistic. In other words, if they see an open door or window or if it is obvious that no one is at home and if there is no obvious security, then it is worth them attempting to get in. Open gates are also an incitement. So are valuable possessions put on show in windows.

It only takes minutes to steal something, you would be astonished. I let two armed robbers into my house and they timed 15 minutes to take everything of value in my house and then a car stopped outside to pick them up. It was night time and I was tied up. It could have been a taxi, which would not have aroused my neighbours’ suspicion.

It is imperative to show people (opportunistic thieves) that you have a home security set-up of some type. If you cannot afford a good, working alarm system, get a dummy siren box with a flashing light. It is not as good as a proper system, but it would take a brave or desolate burglar to find out, which means that you cannot tell anyone at all, in case it gets out.
