Different Types of Indoor Security Detectors

Monday, April 20th, 2009

In the movies we often see break-in scenes where a burglar bypasses or is caught by a variety of different detection systems. Often these systems are fabricated or made-up to enhance the drama and action. But sometimes the technology we see in the movies is a real and available source of security. Here are just a few of the types of technology for indoor alarm devices that are actually available today. Though many of these may be typically used only in industrial alarm systems, some are used in more advanced home security alarm systems.

Passive Infrared Detectors

Because it is affordable and reliable, the Passive Infrared Detector (or PIR) is one of the most common types of detection used in homes and small businesses. The PIR monitors the ambient temperature of the desired space for change that might be caused by an infrared emitting object or person. It uses the principle of differentiation, which checks presence or non-presence to verify if a person is actually there.

Ultrasonic Detectors

Ultrasonic Detectors are active detectors that emit an ultrasonic wave that is inaudible to humans. The sound waves are transmitted by the receiver, reflected off hard-surface objects and then detected by the receiver. The device will detect a change in wave frequency that is caused by motion.

Photo-Electric Beams

This device transmits photo or infrared light beams across an area where the beam might be obstructed by a moving intruder. This device, because of the dramatic nature of its technology, is popular in films. One problem with this device is that it can sometimes be avoided if the intruder is aware of its presence, making it somewhat less reliable than other methods.

Glass Break Detectors

Glass generates sound in a wide band of frequencies when it breaks. Glass break detectors are mounted next to the glass panes and listen for the frequencies that are associated with breaking glass. Seismic glass break detectors are installed on the glass itself and detect the shock frequencies that travel through the glass, frame, and even walls.

These are just a few of the types of technology available today for security systems. Some advanced home security systems, such as the devices employed by ADT, may use these types of alarm devices or even more advanced types of detection devices. So, although in some cases the technology we see in the movies may be fabricated, much if it is as a result of real modern advances in security.

The Fire Proof Safe – An Essential Item in Your Home

Often times when we see house fires on television we think that this type of unfortunate event will never happen to us. Unfortunately, those that have lost everything in a fire have thought that very same thing.

No matter what extremes we go through to keep our home safe from theft, fire and even Mother Nature, the fact still remains that these things do sometimes still occur. All the fire alarms and home security devices cannot totally prevent a break in or a fire so what is it that we can do to help keep our irreplaceable, invaluable items safe. One item we can purchase that can keep possessions and documents safe in the event of a fire is a fire proof safe.

Some unfortunate people have experienced losing everything they have due to a home fire. Since fire leaves almost nothing but soot and smoke, it has the capacity to destroy everything that exists in the home. Aside from having home owners insurance, a family can protect themselves even further by buying and using in a fire proof safe. A fire proof safe is proven effective way to in safeguard your important documents, money, and jewelry against fire.

Fire proof safes are tightly secured by virtually crack-proof locks, they offer protection against burglary as well as fire. In a typical safe, such as a fire resistant safe, when a fire occurs the body of a safe is immediately destroyed or heavily damaged by fire. This damaged safe is then easy to crack open and steal whatever remains inside. This is not the case with a fire proof safe.

Fire proof safes are specifically designed to withstand certain ranges of very high temperature and direct contact with fire, they are less likely to be damaged, and therefore opened after the fire by a thief. Some fire proof safes are even specially designed to have insulation inside their compartment, which prevents heat from melting or breaking some or all of its contents. Fire proof safes provide an easy way of protecting everything you value at a reasonable cost.

Fire proof safes can be found online or even at your local security store. It is important to find out all the facts about the fire proof safe you require and what exactly will be contained within it. Remember that the right fire safe for you will depend on what you intend to store inside. Once you have determined that an expert can help you choose one that is right for you at a price you can afford.
