The Different Types of TV and How They Work

!±8± The Different Types of TV and How They Work

If you have ever wondered how a TV show you are watching gets from who-knows-where to your TV? Well there are a lot of steps involved in getting the signal from point A to point B. There are also many components and gadgets used to get it there.

When a show is filmed the broadcasting service gets that video, and then uploads in to the TV satellite dish. A broadcasting station is a building that broadcasts the recorded programs to a TV satellite dish or analog cable. This building is also used to broadcast live shows, such as news or sports games. Now you, as a subscriber to this service, get access to those uploaded videos. Depends on which service you have, digital or analog, there are different ways to obtain it.

In analog, the video quality is worse than digital and is also worse than your average computer screen resolution. If you take into account that television has been around long before computers, it is weird that the resolution is still as low as it is. The analog signal is transferred through antennas and receivers. This service is not available in many parts of the world, and that is where digital comes in.

Digital is the best quality television, and is ten time better than the best analog TV. For this you need a computer style monitor, or a HDTV. The signal is better than analog because of the pixels. The pixels in a digital screen hold a much greater amount than analog TV.

A TV satellite dish is placed atop your house and then gathers signals from a satellite that is in space. The signal is then transferred to a receiver located on your television. A receiver is a box that collects, decodes, and translates codes of the television broadcasts in order for your TV to read it. HD channels are only available to a TV that can read HD codes, i.e. a HDTV.

The Biggest Oversight When Hanging Your Flat Screen TV On The Wall

!±8± The Biggest Oversight When Hanging Your Flat Screen TV On The Wall

So you've saved up your money and now going to buy a flat screen TV. Perhaps you have settled on a LCD or Plasma.

I hope you didn't spend all of your money on the TV because there a few things you may want to budget for if you are not particularly handy around the house.

Where are you going to install your Flat Screen?

If you are going to mount your TV on the wall there is something very important for you to consider

Do you have a TV outlet installed at the height you want your TV? Even if you said yes...I am sorry it will not be enough. Allow me to explain.

Can you picture where your existing TV is set up? Maybe it's in an entertainment center. Now close your eyes and see all of those wires that connect between your Television & your satellite box, DVD player and receiver.

Why do I bring this up?

If you hang your TV on the wall with a standard TV jack installed there-

What about all of those wires that we just talked about? How do you plan on connecting all of those wires that are needed to work all of your electronic equipment?

I told you that no one thinks about this.

Unfortunately, with a single cable TV jack over the fireplace...your ONLY option is to stack your:

· Satellite receiver

· Cable TV box

· Surround sound receiver

· DVD player

All on top of your beautiful fireplace!

Or have a bunch of ugly wires draped all over the place serving as a serious tripping hazard

Can you imagine moving into a beautiful new home and seeing all of those pieces of equipment balancing on your mantel?

You would be surprised how many new homes are built this way. They install just a simple TV jack over the fireplace. The homebuilders are totally clueless. Unfortunately, its up to you, the homeowner to foot the bill to wire this correctly.

So what can we do about it?

If you want the best signal possible, Then HDMI cables are the way to go. One HDMI cable run thru the walls will do the work of all of those other wires we spoke of moments ago. To have this professionally done I would budget from 5- 5 for HDMI cables, depending on how long they need to be.

You can probably save two hundred dollars if you do this yourself.

Remember that buying the flat screen TV is just the beginning of your investment to have HD TV in your home.

!±8± A Quick Look at the Lorex LW2702 Wireless Surveillance System

Lorex is an international leader in video surveillance solutions. It offers consumers a wide range of products that include wireless security cameras, network security cameras, observation systems, security DVRs, and surveillance systems. In this article, we will take a look at the Lorex LW2702 Wireless Surveillance System.

This model has just been released and is already receiving accolades for its many innovative features. Of special mention are the digital wireless cameras that have a range of 450 feet, and 40 feet in night vision mode. The receiver is built into a seven-inch LCD screen that can record what the camera stores on a SD card. The system can be connected to a television for big screen viewing via an RCA output.

The LW2702 is a perfect starter kit for small office suite or a modest home. It is very easy to set up and use. Using Ultra Digital Wireless technology that offers homeowners the very latest advancements, it is able to minimize interference caused by other equipment like cordless phones, wireless routers, and Bluetooth devices. Image quality is also excellent, as is the sound.

There is a secure connection between the cameras and the receiver which gives the homeowner complete privacy.The out-of-range notifications and signal strength functions help you to find the best spot to install the cameras. The LCD monitor has an inbuilt video recorder and a wireless receiver. The system comes with five images for display use on the monitor,for when the camera system is not in use.

The SD memory card can hold 16 GB. Recording can be pre-set to various modes, i. E. When the camera detects motion, a daily time recording, or a manual start and stop recording. Searching for a particular event is made easy with date-stamped recordings. If you want high resolution, you can record at 640 x 480 VGA. For maximum recording time, set the resolution at 320 x 240 QVGA.

The cameras have a two-way intercom function,as well as IR Night Vision. They are covered in a robust metal housing which makes them weatherproof so they can be used outdoors as well as indoors. The cameras images can be set to rotate,or you can view them one at a time or all four at once, the choice is yours.

The intercom function enables communication between the cameras and receiver. Therefore, you can speak and listen to the person in the camera's immediate area. An on-screen menu facilitates easy changing of the settings and also makes searching for recordings quick and simple. The system displays each camera's signal strength on the screen.

The LCD receiver looks just like a digital picture frame and has a minimalistic and clean design. There are no buttons on the front of it. At the rear, you will find the speaker for audio, the antenna, the SD slot, the on/off switch, and a stand for use on a desk or table. There is also a wall mount, an AV port, and the navigation menu and talk button for the intercom.

One of the most useful features on the Lorex LW2702 Wireless Surveillance System is the PIR (Passive Infrared) sensor. Most DVR cameras activate when the pixels change which means that you often get unwanted recordings, e. G. A tree moving or an animal walking past. With the PIR function, recordings will only start when body heat and movement are picked up by the sensor.
