Misunderstandings About Wireless Security Technology

Wednesday, June 16th, 2010

In the security industry there is trend of misusing the word ‘wireless’. I want to try and clarify some of the misuse. The term wireless security system is currently being used to describe an expertly installed system with wireless contacts, a wireless phone communication device, and a do-it-yourself security system. There is a huge difference in the three.

A professional installed wireless system is identical to a hardwired system that consists of a main control panel hidden away with all the same components, keypad, siren, contacts, and/or motion. There, components would be wireless in cases where hardwiring is impractical or impossible. Your protection is still essentially the same. Any destruction to the system will cause an alarm, and signals will instantly be sent to your monitoring center.

One of the most notable misuses of the term ‘wireless alarm system’ is the wireless phone communication. This transfer of information works the same as with a hardwired or wireless alarm systems. Adding a GSM/GPS cell module to the security system, hardwired or wireless, allows this service to work. This phone service is used in place of a cheap landline phone or voip phone, and provides safe communication at a lower price.

Now the do-it-yourself is the hardest to solve, but I will make the attempt. Seeing that it is a system that can be installed by the average housewife, naturally it uses wireless components, and there is no main control panel. The system has a self-contained keypad/control panel all-in-one. This system is designed to be moved by the homeowner in temporary housing. These systems are obtained by online alarm companies that ship them out to the homeowner and he installs it himself/herself. If it’s too complicated for them, the company can sub someone to install it at a fee. Now there are some companies that sell these system as permanent professionally installed systems. There are pros and cons to this type of system. A pro is that it is inexpensive to install and can be moved easily. A con is it can be removed with ease by an intruder, it is not good for long-term, and it limits you to one company for monitoring. This system can be easily defeated by removing the all-in-one keypad/control panel.

As technology changes, so will the way people search out information. Information on security systems is being delivered by a modern generation of salespeople and purchased by a new generation of customers. No matter, a professional hardwired security system is always essential to have. If several wireless products are needed as well, that’s fine, as long as the bases of the system is hardwired. When it comes to your communication, it must be viewed in the proper lighting. Your phone is the way in which all systems communicate, one landline phone, voip phone, or GSM/GPS cell; all three cooperate with your security system. An indication that the term wireless security system is being misused is if a homeowner asks for one, and in that case it needs to be clarified.

Tip For Choosing A Suitable Sound System For Your Television

Monday, December 28th, 2009

When designing a new home theater system, one of the most important things to consider is the sound. Installing a new surround sound system can enhance your home theater experience, making it a more complete setup. While the installation may or may not be easy, depending on the type of system you choose, it will be worth it when you have it completed.

Any time you can savor a job well done is good. So you want to hook a surround sound to your new 52 inch flat screen television? Where do you start? First you have to decide how much you want to spend. Are you looking for the ultimate movie experience and looking to impress your friends and family? Unless you are Usher or Lil Jon, you might not be able to build an actual theater in your house. So those of us on a budget can still get great results without having to sell a kidney on the black market.

If you are looking for a less complicated solution, many manufactures offer a home theater system in a box, which includes all of the necessary pieces for your surround sound system. The package typically includes a DVD player/tuner or a stand alone tuner, all of the necessary speakers, and color coded wires that make installation easy.

First, you can get what is called a sound bar. A sound bar is a speaker that sits directly over or under your television and mimics a surround sound speaker by having multiple channels of sound. It usually has a separate sub-woofer that sits on the floor next to the TV. It is a trick of sound that make your ears believe that they are hearing surround sound. An advantage to this set-up is the ease of setting up the system and only having a couple of components to hook up.

The most common home surround sound system is the 5.1 channel system. This home theater system includes a center speaker and two side speakers for the front of your room, two additional speakers for the back of your room, and a sub-woofer for the bass. This system is the best available option for a DVD player or high definition set top box. Some systems even come with wireless speakers for the rear, so you do not have to worry about running cables across the room.

The newest option in home surround sound systems is the 7.1 channel system. The setup for the 7.1 channel system is similar to the 5.1 channel system, with the addition of two speakers that are places in the middle of the room, on opposite sides of the viewing area. The 7.1 channel system is the ideal system for Blu-ray movies, since these movies offer a higher quality of sound then a standard DVD.

Audio cable and speaker wire is needed for your in home surround sound. If you are searching for these items take a look at www.selbyacoustics.com.au.
