!±8± How to Guide - Connecting Your Laptop to HDTV Or TV

I'm writing this guide after being asked a few times on ways to connect a laptop to a TV. People want to achieve this for several reasons. First, it's great for presentations at work, school, or home. It's also convenient for viewing pictures and videos to friends, watching DVDs, and it is now even being used for viewing Blu-ray and other high definition content on the HDTV.

First, we want to make sure you're getting the most out of your laptop when it comes to displaying it on the TV.

If you have an HDTV with HDMI inputs, check if your laptop has an HDMI output. If it does, you're in luck! Your HDTV can display from your laptop in HD resolutions. All you need is an HDMI cable to connect them. If your HDTVs HDMI inputs are used up already. An HDMI switch would be the best solution for you. We supply switches that can connect up to 5 different HDMI sources to 1 HDMI input. If you don't have an HDMI output on the laptop, check if it has a DVI output. Some ASUS, and Dell laptops have them. If you do, you can connect your laptop to an HDTV with an HDMI to DVI cable. They are both digital cables so this will produce the same HD resolutions as a standard HDMI cable. If your laptop doesn't have HDMI or DVI out, it should have a VGA output. Connecting with VGA is capable of high resolutions. However, different TVs support different resolutions with VGA. You must check the maximum resolution your TV model supports with VGA. Pretty much all laptops come with an S-Video output. It's not going to be as great of a picture, but it will certainly do the job with an S-Video cable.

After you have connected your chosen cable, boot up your laptop and see if it has detected your TV. If not, you have to go into your display properties and look for the settings that will enable your TV to display from your laptop. Where to find the setting will vary depending on your graphics card (just look around). If you are having trouble getting your TV to show a picture, make sure you have updated the display drivers on your laptop. Now you're probably going to want sound from something other than your laptop speakers. So you can choose to output it to your TV, or blast it from your home theater audio receiver.

The best way to connect audio to your TV or receiver is through a digital audio cable. Both a digital coaxial cable or Toslink optical audio cable will work great for crisp high quality audio. Just make sure your laptop has either a digital coaxial or an optical audio output. Some laptops use the headphone jack to double as a digital coaxial (S/PDIF) output. If you use this method, your going to need a 3.5mm to RCA adapter with a digital coaxial cable. If your laptop has none of these outputs and you still really want that high quality sound. Don't worry! You can still get an external (USB) sound card that has digital coaxial out or optical out. I recommend the Creative Sound Blaster X-Fi Surround 5.1 SB1090 with Toslink Optical audio out. Another way, which won't require any add-ons, is to use the headphone (3.5mm) jack on your laptop to the RCA (red and white) inputs on your TV or receiver. To do this, all you need is a 3.5mm to 2 RCA adapter with a 2 RCA audio cable.

I know all of these cables can seem confusing to you. If you're having trouble finding out what each cable looks like or find out more about a cable, check out the Cable Guide at CableTrain.com. All of these cables are available for you on our website as well. I hope you can now successfully connect your laptop to the TV in the best way possible!

Tips For Installing Surround Sound

!±8± Tips For Installing Surround Sound

If you're installing up a home theater you should seriously consider installing surround sound - otherwise you'll be missing out on a vital part of the home theater experience! Although ordinary speakers will mimic the sounds of the movie, the surround sound speakers will provide greater quality and make you feel as if you're sitting right in the center of the action on the screen.

Good surround sound speakers will come with a digital media port which will provide even more flexibility. This enables you to play music from your iPod, computer, or any Bluetooth equipment. By utilizing this port you can take the audio on these other devices and channel them through the surround sound so you can enjoy the amazing tone and range that the speakers can generate.

When you are looking for the best in quality sound, keep in mind that you must consider having between 3 to 5 wall mountable speakers and a sub-woofer. Ideally, the best way to place these speakers is to have two front speakers, a sub-woofer, one center speaker and two rear speakers. This way you will have the sound surround system you want.

Installing surround sound speakers can be trying at best, given the excessive wiring on the floor, under the floor (along with the drilled holes that requires) or worming against baseboards, it can be a daunting task. However, you can eliminate all this trouble by buying wireless speakers!

There are additional specifics you may want to look for. For example, if you want to put your center speaker close to the television, buy one that is magnetically shielded; otherwise you run the risk of distorting your image. (Make sure you know before you buy if this is the way you want to arrange your solution.) The sub-woofer you buy also needs to have its own power supply.

Finding the right receiver is crucial for your Surround Sound experience. The ideal receiver will allow you to control movie and music output separately, to plug in headphones and other accessories easily, and has at the minimum a 4-channel Dolby Pro Logic decoder. Additionally, Auto Calibration and Digital Cinema Sound will provide the crispest listening experience. Finally, buy the highest-wattage receiver you can afford.

Installing surround sound is very time-consuming and complicated, so you may wish to get a professional to do the job. Picking the right receiver and speakers is truly the most critical part, so after you have done that, you've won most of the battle.

This 50 foot subwoofer cable is made by Blue Jeans Cable in our Seattle assembly shop using our proprietary LC-1 low-capacitance, heavily-shielded analog audio cable stock and Taversoe brand crimp connectors. The most common quality issues in subwoofer cabling have to do with hum, and the LC-1 cable carries an extremely heavy double-braid shield for maximum shield effectiveness at low frequencies and excellent ground contact between receiver and subwoofer. Despite its thickness (.305 inch) the LC-1 cable is very flexible due to its soft nitrogen-foamed dielectric. The connectors are gold-plated where it counts--on the contact surfaces--and grip the RCA jack on your receiver and subwoofer using a set of spring contacts which ensure solid grip without the jack-damaging "death-grip" phenomenon associated with many other tight RCA contact systems.

DIY Home Surveillance - What You Need to Succeed

!±8± DIY Home Surveillance - What You Need to Succeed

Today's world is becoming a more dangerous and scary place to live. Burglary, vandalism, and violent crime run rampant in some areas, and often the police presence required to mitigate the threat in residential areas leaves a bit to be desired. But there are options available for homeowners to protect themselves and their families from this threat, and to help police identify and apprehend perpetrators.

There are companies out there who want to charge consumers an arm and a leg to install a state-of-the-art CCTV or digital surveillance system in the home. But fortunately, you don't have to be one of those people who get taken advantage of. By installing your own digital surveillance system, you can save yourself thousands of dollars, and end up just as secure as your neighbor who paid handsomely for the privilege.

Installing a home surveillance system is a good weekend project. While there will be some manual labor involved, if planned out properly, your project will go smoothly and you will be on your way in no time! Here are some tips to get you started.

1. Identify what you need to watch. Maybe you need a camera to watch your driveway, your back yard, your pool, and your front door. Maybe you just need to watch your baby's nursery. The point is, identify how many areas you need to keep an eye on. This will give you the approximate number of surveillance cameras that will be required for your system.

2. Identify where you need to position your cameras. Now that you know how many cameras you will need, you have to identify where you are going to mount them. This can be accomplished using a floorplan or drawing of your property layout, and perhaps a ladder and digital camera to take some photos of where cameras will go, and what you would like them to see/cover. This should also give you an idea as to what materials will be needed to perform the installation, such as mounting hardware, cabling, etc.

3. Identify what kind of cameras you need. Now that you know how many cameras you need and where you intend to put them, you need to put that info to use in identifying the kind of cameras you need. Is the camera being placed indoors or out? If you are placing the camera outside, it needs to be able to withstand the elements, so you need a camera that is weatherproof, or you will need a weatherproof camera housing to protect the camera.

Is the area being covered always well lit, or is there little or no light available at times, and do you even need coverage during those times? If you need coverage in near or complete darkness, you will need a camera that is either low-light sensitive or an infrared/night-vision camera.

4. Identify what type of viewing and recording system you need. Now that you know how many cameras you need, you already know how many channels are required on your recording/viewing device. Further, you need to identify about how long you need to store recorded video. For example, is this your permanent residence, or a vacation home or cabin, where you might not be there but once every few weeks? These will all be important when buying your system.

5. Identify where the viewing/recording unit will go. Once you know where you want to place your DVR or other recording device, you can easily decide how much wiring you will need to install the system, and get an idea where and how the wiring will be run.

6. Decide which installation materials, hardware, and accessories you will need to install. How long are your wire runs going to be? Will you need to run your power separately, or together with the cable? If you run them together, you can save a great deal of headache by using Siamese coaxial cable, which consists of a shielded coaxial cable, bonded to a two-conductor power line.

If you run your own cable, you may need BNC or RCA video connectors and power connectors for the cameras. Also, depending upon how many cameras you need, you may use individual power transformers (similar to a cellular phone charger), or go for a distributed power box instead.

On the mounting side of things, you may need mounting brackets, housings, and other additional hardware (screws, nails, etc).

Once you have accurately identified what you need, it's just a matter of calling our friendly and helpful sales team for help choosing the right product, or making a visit to our online store to place your order, anytime day or night. You'll have your product in just a few days, and be ready to move forward with your project.

At this point you should have a pile of information and hardware at your disposal. Here is a quick checklist of everything you should have:

- Cameras

- A Viewing/Recording System

- Power Transformer(s) for the Cameras

- Cable(s) (Video and Power)

- Connectors (unless you have pre-made cables)

- Camera Mounting Hardware and/or Housings

- Instruction Manuals for all of the above.

- Spare parts (in case you make a mistake)

Additionally, it can be a big help to have a "field monitor" on hand when installing your cameras. A "field monitor" is a handheld video screen that you can connect directly to the camera while on the ladder, and will help you get the camera in just the right position before you come down. This will save you tons of headache and hassle as you install your equipment, and will help ensure a good install on the first try.

Before you install, here are a few other things to know:

1. Know the laws regarding surveillance in your jurisdiction. For example, it is illegal in some jurisdictions to record video AND audio. In others, it is necessary to post that surveillance is taking place. If you don't already know what the laws regarding surveillance are, consult your attorney or your local law enforcement agency for more information.

2. Know the building and fire codes for your jurisdiction. Some states require special types of cabling to be used (such as PLENUM), where others require such installations to be handled by a licensed electrician or installer. Other areas may require you to have some type of building permit to install surveillance on your property. It's best to check with your local building inspector to find out for sure.

3. Know that all your equipment works before permanently installing it. Some folks make the mistake of not testing the equipment right out of the box, only to find that they installed a camera that was damaged in transit on the peak of their roof, and it takes several hours more to take down the bad camera, and again to reinstall it after a replacement is received.

Finally, remember, SAFETY FIRST!! Don't get into an install that you are not physically capable of, or that you lack adequate knowledge or experience to perform. Be especially cautious working around other electrical wiring and utility connections. Having great security is worthless if you're dead.

Latest Innovations on Computer Speakers

!±8± Latest Innovations on Computer Speakers

Computer speakers are external devices which produces sound coming from a computer or any attached multimedia device. It improves sound quality electronic devices cannot do on their own. These speakers come with a built-in amplifier to better magnify sounds from audio devices like mp3 players, iPod, CD players and personal computers.

Most of the computer speakers use a standard 3.5mm stereo jack to connect to computer systems. The stereo jacks are colored lime green for easy recognition based on the PC 99 standard used for all computer sound cards.

Some of the latest models in the market today come with multi connectors such as an RCA jack. It makes it easy to plug the speakers in TV sets or DVD players. Latest models also consist of built-in equalizers, treble and bass controls for better enhance sound.

Common CCTV DVR DIY Mistakes

!±8± Common CCTV DVR DIY Mistakes

This article will attempt to reveal some of the more common mistakes to avoid when creating your own CCTV DVR.
Budget: Many DIY'ers simply do not budget enough money for projects like this. When looking at cameras, look at the specs. A 0 security camera and a security camera are going to be very different in terms of image quality and light response. Also look at CCTV DVR features. Places like Costco offer surveillance systems for under 0 but those surveillance systems don't have anywhere near the features of professional grade systems like Video Insight. Those systems can even be missing basic features like video motion detection. You may want to look for surveillance packages that combine everything you need to put a system together, including the CCTV DVR, security cameras, security camera lens's, mounts, power supplies, and cable. Packages like that can start at about 00 and go up to ,000 depending on the number of security cameras needed. Surveillance Camera Placement: Surveillance camera placement is one of the most important factors in an effective surveillance camera system. Ask yourself the questions professionals do: How is the light coming in? How will this change at night? What am I trying to see? How do people move through the area? What kind of blind spots will there be? What kind of surveillance camera lens do I need to use? Do I need to use multiple surveillance cameras to cover this area? Would a side view be better for this then a straight on view? Selecting the right security cameras: When looking at security cameras, understand what you are trying to do. Are you looking for license plate recognition? If so, then you need to select a camera lens that will allow the plate to be at least 1/3 of the image. This means that a surveillance camera with a wider field of view can not do license plate recognition. The same goes for facial recognition. If you are trying to cover a parking lot with a narrow entrance, you will have to use two surveillance cameras. Very wide entrances can make this very, very hard. Selecting the right camera lens: Selecting the right camera lens is pretty easy. Note where you are going to place the camera and select the point where you want the best picture. Measure the distance from there to the camera. That is your focal distance. Then measure the width of the picture you want to see. Once you have these numbers you can feed them into a CCTV lens calculator. Looking at the F-stop will give an idea of how well that lens will work at night. Infrared or No?: Infrared cameras are wonderful for covering areas of complete darkness. But many of the all-in-one camera/emitter units are fairly limited in range. This chart can help with deciding if you need to go the infrared route or not. Direct sunlight: 100,000 - 130,000 lux Full daylight, indirect sunlight: 10,000 - 20,000 lux Overcast day: 1,000 lux Indoor office: 200 - 400 lux Very dark day: 100 lux Twilight: 10 lux Deep twilight: 1 lux Full moon: 0.1 lux Quarter moon: 0.01 lux Moonless clear night sky: 0.001 lux Moonless overcast night sky: 0.0001 lux Focusing the video camera: This is a simple and easy trick to help with focusing the video cameras. Use a BNC to RCA plug and a small television set to focus the video camera. The ideal time to focus the video cameras is in twilight because it will give the best compromise between the light and dark settings of the auto-iris lens. Cable types: There are a few types of cable called RG-59. Copper vs. Aluminum sheet and 75% braid vs. 95% braid. For CCTV system work, you should always use copper shielding. Aluminum shielding is meant for modulated signals like cable and allows too much interference for CCTV systems. 75% braid and 95% braid measure how tightly and how much copper is used in the copper sheathing. 95% copper braided cable is more expensive but worth the extra expense. It is much more effective at preventing interference, and much more forgiving of mistakes. We only sell 95% braid copper shielded RG-59 Cable runs and Ground loops: Coax cable should be kept at least 12" away from any power lines and power conduits. The AC power creates a field of interference that will appear like snow on the screen. This can create havoc with motion detection. Ground loops can be caused by securing cameras to metal structures that have a different electrical ground then the power supply. This will cause bands to move through the screen. Solving this is a matter of eliminating contact between the cameras and the source of the ground. Sony Cameras: Sony has a line of CCTV surveillance cameras, but all of them are clearly marked Sony. You will see a lot of sites offer "Sony" cameras when they don't say Sony on them. The reason for this is that Sony makes about 75% of the worlds CCD chips, which are used in everything from Camcorders to digital cameras to CCTV security cameras. The CCD is an important part of the security camera and has an impact on the resolution, but the electronics behind the CCD also have a big role in how good your image is. What determines how good my image is?: How good your image is depends on quite a few things. It depends on how good your lens is, how well it is focused, what the resolution is, and how good the S/N (Signal to noise) ratio is. When looking at a camera, you generally want both the highest resolution and the highest S/N ratio you can find. The Signal to noise ratio is a Logarithmic scale so the difference between 46 dB and 48 dB is a rather large difference. If forced to select between a camera with a slightly lower resolution and a high S/N ratio or a camera with a higher resolution and lower S/N ratio, try to select the one with the better S/N ratio if you are doing longer (500 ft+) cable runs. For shorter runs going with the higher resolution is okay. How many FPS do I need?: Many manufacturers and distributors will try to push their highest frame rate DVR's and Cards on you because those items have the best profit margins. But high frame rates may not be in your best interests from both a storage and budgetary perspective. For most applications 3 to 7 fps is fine. If your goal is to identify theft or vandals then 3 fps is almost always enough. The only time one should consider more then 15 fps is if you have to watch for sleight-of-hand like watching a register. The reason to avoid higher frame rates is that they take up more drive space, reducing the total storage time of the system. It can also divert budget away from selecting the right cameras which is far more important and more likely to generate usable evidence then a higher frame rate. Audio Recording: Don't do it! In many states it is illegal, period. It does not matter if it is your home or other private property. The law only cares about if the people being recorded are aware that they are being recorded. A number of people tend to think "Well, I'll put it in anyway, it's not like someone is going to report me." The problem with that line of logic is that if you ever submit video as evidence to a court and you are in violation of your state's laws or federal laws, then you have just given proof to the courts that you also committed a crime. The best possible outcome is that the court throws out the recording and you don't go to jail. But if you can't use your recordings to help convict a person that has wronged you then what good was the money you spent? CSI: As a general rule of thumb, anything you've seen done on television or in the Movies with video enhancement is simply not possible in the real world. You can't make data appear where there is none. There is no magic trick to make that work.
