What is Structured Wiring?

Structured wiring is a bundle of wire that usually includes RG-6 (coaxial wiring) for multi room video such as Cable TV, and Satellite TV. Structured Wiring also includes Category 5 (or better) communications wiring for Telephone wiring, and Computer Networking. Adding Multi-Room audio is also a popular add-on. Audio systems can be installed using just speaker wire, or a combination of Cat5 and speaker wire.

Common Structured Wiring Requirements Include:

  • Multi-Room Video Wiring, for Cable TV & Satellite Dish
  • Multi-Room Telephone Wiring - Telephone structured wiring is typically done using Cat 5. Computer Networking
  • Computer Networking - Networking of Computers, and other devices will only grow over the next decade - This should never be overlooked, structured wiring your home for computer networking is vital for future products.
  • Audio Distribution - Structured Wiring your home for audio, and intercom is a very popular requirement for all new structured wiring projects. This will allow you to listen to your favorite music, in any room of your home.
  • Infrared (IR) Distribution - IR Distributing is sometimes built-in to an all-in-one multi-room audio system - This will allow you to use any remote control, from any room, to control any remote function. This will keep you from running all over the home to change a CD track. If your Audio System does not have it built-in, you can easily add IR to any room with Cat5 and an IR Receiver.

"Structured Wiring VS Traditional Wiring"

Both using the same type of wire throughout the house.

Honeywell (Honeywell) Security Systems

A security system starts with a control panel. Usually located in a closet or a basement, the control panel contains the “brains” of the security system, and essentially operates as a central computer. Various sensors connect to the control panel from locations throughout your home. If your security system is armed and the sensors detect a problem, they send signals to the control panel. The control panel automatically dials the central monitoring station, where the proper authorities are notified.

Hardwired Home Security

Hardwired Security Systems are still possibly the most common type of security - Typically recommended for new construction. Hardwired systems typically cost less than wireless systems, but take more time to install. However, If installed during the construction phase the installation time is very little, making wired systems the preferred choice.

The advancement of home security systems, and the reduction of price over the years has led to it becoming almost as common in new homes as Cable TV. Many new home owners realize that their home is their largest investment, and the best way to protect it is to install a security system at the time of construction.

Adding Sensors after construction is a common decision. Some things may be over looked at the time of the original installation, or possibly something changed - All of our wired security systems can be updated to work with wireless sensors - Making it a Hybrid wired / Wireless system as described below.

There are many hardwired security kits, pre-configured to meet anyone's needs

Home Security Sensors

A home security system consists of many different sensors types - Each accomplishing a separate task. Knowing the difference in these security system sensor types, can make the difference in price, and overall security.

Security System Motion Detectors

One of the most common sensors you will see on a home security system is a Motion Detector. These sensors use Infrared, or Microwave sensors to detect movement within a room. Many motion detectors are made pet immune. This will allow you to arm the system, while your pet still roams around the home undetected.

** Best practice is to place a motion detector directly in a corner. The placement of a motion detector is vital to how it will detect movement. Most motion detectors have built-in "Zones" to protect against false alarms. These zones are mapped so a person will have be detected moving through one or more of these "Zones" - This means a person must taking 2 or 3 steps past the motion detector, before detection. Because these zones are mapped typically from right to left - Having a motion detector placed in an area where someone has to walk past it, NOT towards it will work the best. We have found a corner will work best 9 out of 10 times.

Door / Window Security Sensors

Door Window Sensors are another important addition to any security system - These sensors are simple - The detect any thing that opens or closes. They consist of 1 magnet, and 1 magnetic sensor. When the sensor is moved close to the magnet, a small relay called a reed switch closes. The security systems watch for this sensor to open, and close, so the security system always knows if your door is open, or closed.

Glass Break Detectors

Glass break detectors work by detecting the sound frequency that is generated from breaking glass. Some also detect a change in pressure in the room at the same time, reducing false alarms. A glass break detector can have up to a 40 foot range. So, if you have a room with multiple windows, one sensor should protect them all.

Smoke Detectors

You should always use these in conjunction with your state code required smoke detectors. Adding a smoke detector to your home security system is a good idea, to quickly dispatch the fire department so you can escape as soon as possible. If there is a fire, a you you can exit and not worry about having to call the fire department because your monitoring company will take care of it. If you are away from home, you will have the same feeling of security, because the home is monitored for fire 24/7.
