When it comes to Walkie Talkies, many folks get confused by claims of manufacturers about range. It probably would help if someone cleared the air on this, to help out those trying to sort out the ridiculously high claims of range on many Walkie Talkies. The chart below will simplify things for most folks:
Range Claim Power Actual Urban Range Minimum Range
8-12 Miles 1 watt 1/2 to 1 Mile 200 Yards
18-20 Miles 2 watts 1 mile 500 Yards
27-30 Miles 4 Watts 2 miles 1000 Yards
Keep in mind that very challeging radio environments will quickly cut your range to the absolute minimum ranges seen here, or to something between this and the urban limits. Only lots of height will get you to the maximums claimed by manufacturers. In any case, I’m told the manufacturers test their radios under decidedly unrealisitic conditions, using facilities in the unobstructed flatlands of Florida equipped with elevated testing platforms.

Night vision goggles give you the ability to view images in near total darkness. In the past, night vision goggles have been used exclusively by law enforcement agencies and the military. Now, they are also available to the wider public.
If you click through to lookoutsurveillance.com.au you will find a wide range of other surveillance items that are available to you.
How night vision works:
Did you know that the majority of night vision goggles have three main components:|
1. image intensifier tube|
2. water proof frame|
3. mounting mechanism?
They work in the near infrared band, detecting ambient light reflected on the area being viewed. The image intensifier tube in the night vision goggles then amplifies faint light by use of the photoelectric effect. The technology of these night vision goggles is truly amazing. Take the tube for example. Photons of light go directly to a deflector plate and then this deflector plate ejects a number of electrons. Those electrons are then amplified into a surge of more electrons. The electrons are pulled towards a phosphor screen by an extremely powerful electric field and so at the electron impact point, light is produced. This allows the phosphor screen to produce a bright image.

If you are an amateur film director, you know well that technology means all for your movies.
Whether it is high definition, or special effects added to your scenes, having the possibility to use the latest developments of cinema technologies can only hep improve the quality of your images.
And if you are into documentary movies, you may want to add aerial views of the ground, or in-flight images, to provide a different point of view.
To do this, you no longer need to invest large sums in renting small aircraft and expensive equipment, since all you need is a small Air Camera.
An Air Camera, as the name goes, is a digital videocamera mounted on a small helicopter which, depending on models and characteristics, can fly up to 20 minutes, with a video camera range up to approximately 700 meters.

Portable power packs have been around for a while but are starting to gain in popularity; partly because their cost has come down and because they are extremely useful products. I personally own a Xantrex 300 plus and have used it on several occasions. Once on a hot summer day at a shopping mall, a fellow having a bad day ask if I could help him jump start his car. I pulled out my Xantrex Power Pack 300, that had been in the trunk for almost a year, attached the included jumper cables to his car and volia, his is car started right up.
A portable power pack is a device that has a powerful sealed battery, an inverter, jumper cables, a DC outlet (cigarette lighter style) and an AC outlet. It also includes a bright fluorescent light with two tubes and a small pump with pressure gauge, to inflate your tires. The 20 amp hour rechargeable battery (in the 400 and 300 plus) will power a cordless telephone for up to 40 hours, a laptop for 6 hours and a portable stereo for up to 25 hours on a fully charged battery. They can be recharged from a standard wall outlet with the included AC charger.

When televisions
first came out, they were very basic and most of the time could be serviced in the viewers home. The first televisions had a very washed out picture that wasn’t very crisp at all. Maintaining a good signal involved adjusting the antenna numerous times during the coarse of a viewing day.
Earlier televisions in most cases could be serviced in the home by the owner of the television. Inside the set there were a series of transparent glass tubes the size of salt & pepper shakers. If one of these tubes went bad, it was usually apparent by the tube showing a fogged glass or chrome like burn mark inside the glass. Replacing the tubes were very easy. They simply unplugged from the inside of the set as easily as unplugging a lamp, then plugging the new tube in, in it’s place. For tubes that were a little harder to diagnose as bad, you used a device called a tube tester. Back in the early days tube testers were available in all television repair shops and most major drug stores and were free to use by the public.
Earlier televisions also had another feature that was rather un-enjoyable to deal with compared to the sets of today. This feature was known as the fine tuner. This was usually a ring dial located around the channel selector knob and was responsible for fine tuning the signal for it’s strongest reception.

Abstract
When looking to select an infrared camera, it is extremely important to better understand the attributes of these cameras that most impact the quality of the infrared images that are produced. This paper covers the three primary areas that influence thermal image quality: pixel resolution, thermal sensitivity and fixed pattern noise. Each area has a significant impact on thermal image quality.
If you’ve purchased a digital camera in the past, your purchase was likely influenced by your belief that the number of pixels was the most important specification when trying to judge image quality between all the camera choices offered. For anyone that reads Consumer Reports™ and their detailed evaluation of digital cameras you’ll appreciate that camera performance includes careful analysis of much more than the pixel count. Because a thermal camera is basically an image converter (radiant thermal energy to visible image), you need to understand what are the primary attributes that determine thermal image quality and how they each contribute to the image quality that you may be experiencing in your application.
Pixel Resolution
The first consideration is the number of pixels. Today there are three resolution standards (some manufacturers’ cameras deviate slightly)
* Low Resolution - 160×120 (19,600 pixels)
* Medium Resolution - 320×240 (76,800 pixels)
* High Resolution - 640×480 (307,200 pixels)

When it comes to saving energy and electric bill in a household, big items like washing machines, refrigerators and air conditioners usually come to our mind. These are appliances with some of the biggest consumption of electricity in a typical home. They are indeed good places to start looking for opportunities to make substantial energy savings.
Having said that, it is also important not to overlook the electrical consumption of various electronic items around the house. Many of these units may look small with few mechanical moving parts. Intuitively you may think that they can’t possibly use that much electricity. However, this is not always true. In fact, using an electricity monitor, some folks found that their particular combination of TV and cable box actually used up more energy than their refrigerator. So seemingly small electronic equipments can spring surprises in terms of energy consumption. Furthermore, even if these electronic items individually are small users of electricity, their collective energy consumption adds up to a considerable amount because there is usually a fair number of them in a typical household.

Buying a television these days is no simple task. When you walk into a showroom or begin to browse the vast selections online, most of us become overwhelmed by the seemingly endless
choices. Where do we begin?
With all of the changes in television technology these days, it pays to have a little understanding of the key developments & features before heading out with the credit card. Below we will attempt to explain the advantages of the LCD technology so that you may be an informed buyer & therefore be happy with your final purchase.
What exactly is a Liquid Crystal Diode?
LCD technology is relatively complex and improving all the time, but is based upon the fact that liquid crystals are in their natural state, twisted. The ability of the crystals to allow light through can be altered by applying electric current. Very simply put, a light source is shone through a liquid containing crystals held between two polarized screens. By applying the correct quantity of light passing through, the desired display is produced.
