Driveway Alarm Systems? Definitely
Summary: Driveway alarm system has become a redundant to nifty little gadget. Find out the reasons why I think so
Driveway alarm system has become a redundant to nifty little gadget. Why, because with them I can spot visitors (unwanted or wanted) far before they hit my front door. Courier, morning milk, no one wants to miss those. Your boisterous neighbors or your shameless in-laws, driveway alarm systems can get you ready long before they began stomping on the porch. Think how else could you get the opportunity to turn off the television and sneak upstairs. Or lock the refrigerator and larders before they began raiding it bare. Nifty little gadget, dont you think?
Technology made it possible for driveway alarm systems to go wireless, thus increasing coverage area and decreasing probability of discovery. Because casing robbers will eventually check for motion detectors and wires do point out a sign that usually says yes, cut me just right here.
Why, you could now listen to the gossip that takes place within the boundaries of your fence thanks to the 2 way voice communication device that is included on most models. Then you could just share that cheesiest tidbit of gossip you always want to let out. Or you could crank up your disc player into the communication device if you found out that the gossip was about your latest exploits.
Okay, thats the farthest you can go. Yes, Im talking to you, on a polka dotted sweater.
The wireless motion detector of the driveway alarm systems is real handy indeed. Not only will the polka dotted gatecrasher be notified that its your property already, youll be notified who approaches; especially effective if coupled with a camera. With multiple motion sensors, your entire backyard will be covered. No mouse can penetrate your hole without passing your intense scrutiny.
Ah, so you see a problem. Well it goes like, what if a cat and a dog and the aforementioned mouse decides to have a little get together picnic on your lawn in the middle hours of darkness. The blaring band parade that goes on and off (or which ever sound you choose to be your alarm or ringtone) will definitely keep you awake. Thankfully, most modern gadget now includes a weight and mass recognition that will allow it to identify the source of the disturbance. Of course it is reprogrammable so you can choose the weight of the trespassers before the alarm goes off.
So you see, driveway alarm system has become a redundant to nifty little gadgets, major thanks goes to technology. They arent for burglars no more. They are part of the household.
Antitheft Alarm Systems
Antitheft alarm systems were once found only on establishments and homes of rich and famous people. However, antitheft alarm systems are now commonly found on the homes of average Joes in the United States. Ranging from simple do it yourself antitheft alarm systems to state of the art sophisticated antitheft alarm systems, from wired alarm systems to wireless alarm systems, antitheft alarm systems provides protection against thieves.
There are two kinds of antitheft alarm systems. These are open circuit antitheft alarm systems and closed circuit antitheft alarm systems. In open circuit anti-theft alarm systems, the alarms are triggered when its circuit is closed (the opening of a window or door will complete the circuit). While in closed circuit anti-theft alarm systems, the alarm is set off when the circuit is opened or broken, the exact opposite of open-circuit anti-theft alarm systems.
Some anti-theft alarm systems have video cameras and motion sensors. Surveillance cameras monitor the perimeter and record events of burglary. Surveillance cameras must be placed on strategic and inconspicuous locations. Some surveillance system record images when the motion sensor detects movements on a particular room or hallway. Motion sensors detect any movement that occurs inside the establishment or house. The sensitivity level of motion sensors can be adjusted so that the anti-theft alarm will not be set off accidentally by animals around the house. Motion sensors are ideal for large areas like hallways and large rooms. Some anti-theft alarm systems have magnetic sensors on windows and doors so that if the windows and doors are opened by burglars, an alarm will be set off.
Some anti-theft alarm systems are monitored by security companies on a monitoring station. These monitoring stations are manned by security specialist. In an event when the anti-theft alarm is triggered, these security specialists will then determine if the alarm is false or not. If the alarm is not false then the specialist will then notify the local law enforcement agency and the owner of the house or establishment.
The four mostly used types of anti-theft systems are the single premise alarm systems, local alarm systems, telephone dialer systems and monitored security systems. The single premise alarm systems protect specific things in the same way as door alarms. The local alarm systems will trigger an audible alarm in case of unauthorized entry and they are not monitored by a security company. The telephone dialer is a type of security system that will automatically dial an emergency number like the police or fire department if the alarm is triggered. The monitored security system is the most effective and reliable of all systems because it is monitored round the clock by a monitoring station.
So if you want to have your property and loved ones protected, have your home and business installed with a antitheft alarm system.
How Fire Alarm Systems Work
Summary: To date there are two types of smoke detectors, Ionization and Photoelectric detectors. Read on how fire alarm systems work
Have you ever wondered how that little round objects attached to the ceiling ever detect smoke? We see it every day, yet a vast majority of us dont know how fire alarm systems work. While were talking of alarms, do you know that a tiny nuclear reaction takes place within that tiny cylindrical object 24/7? Come along and well take a closer look on how fire alarm systems work.
To date there are two types of smoke detectors, and the most commonly used are the ionization detectors. They are cheap, require little space, and are far more effective than the other type which are the photoelectric detectors.
Ionization Detector
Inside the Ionization detector houses a small amount of Americium-241 and two plates of opposite voltage. The voltage is usually provided by a cell and all are housed in an air flowing metal chamber. The actual body of chamber functions as the negative plate and the positive plate covers the Americium. So what does this element do? The Americium generates alpha particles. These particles ionize the oxygen and nitrogen atoms of the air inside the chamber. The event is simply knocking off electrons in the air. As the electrons are knocked off, the air atom gets positively charged and attracts to the negative plate, while the electron gets attracted to the positive plate. Meanwhile, the electrical circuits within the detector senses if there are no disruptions to the pattern.
Because the chamber is open, air passes through freely and gets ionized. But when smoke enters this Ionization chamber, it disrupts the ionization process and the electrical horn within the unit is sounded.
About Americium-241
This element is radioactive, meaning it produces radiation. But the amount within the Ionization Detector is considerably small that the radiation it produces wont pose harmful effects. Plus, the radiation emitted is mostly alpha radiation which has the penetration factor of only a few centimeters. Several inches of air completely blocks it; a paper can effectively block it. Being housed in a metal cylinder would surely pose no harm. Still, discarded Ionization Detectors should be disposed properly. After all, it is still a radioactive element.
Photoelectric Detectors
Photoelectric detectors arent used as largely because they arent that sensitive as most require a substantial amount of smoke to go off. Photoelectric detectors consist of two channels, one is to emit light and the other detects it. If smoke particles are present in the air, this will interfere with the signal and the alarms goes off.
Most fire alarm systems are wired together so if one gets an alarm, all fire systems goes off. Some are even wired together with a water shower that automatically goes off in case of fire.
