Linksys is a popular company that produces top-of-the-line security cameras. They recently released the new the Wireless-G WVC200 PTZ Camera with Audio, more popularly known as the Linksys wireless PTZ Internet camera, and it’s been receiving good reviews.

This web-controlled wireless camera is an appealing and nicely appointed security cam that comes with a unique design and distinct features. From afar, it looks like a small astronaut with its clear astronaut-helmet bubble that protects the actual camera from dust and damage. On the front panel are the LCD display and Led lights, which display the IP address. The plastic bubble case and the IP address are what sets the Linksys wireless PTZ Internet camera apart from the thousands of Internet cameras in the market.

The camera also has practical features, such as a removable stand and holes on its flat back for easy set up. With the stand, you can place the camera on top of tables and shelves. Want it to hang on your wall instead? Just remove the stand, and the holes make it easy for you to mount it up. With its built-in server, you won’t need to connect the camera to a server of PC and up to 10 users can have access to the camera simultaneously.

Setup and Configuration

Setting up the Linksys wireless PTZ Internet camera is not so difficult, since it comes with a setup wizard. The first thing you need to do is to plug the camera into the router through the Ethernet. This is only required during the setup phase.

After doing so, you’ll find the camera on your network. Then you’ll see the camera setup page where you must assign a fixed IP address before you can choose between Infrastructure mode or Ad-Hoc, and Fixed IP or DHCP. After settling on your choice of settings, the final step is to transfer these setting to the camera. If you get more problems, you can easily contact Linksys Technical Support by opening a “live chat”.

Cam Quality

The Linksys wireless PTZ Internet camera uses Mpeg-4 and MJPEG video compression. The 640×480 video quality is good. The images appear smooth with minimum lag. You can also check the video settings where you’ll find that the video’s 25 frames per second is perfect, with the sound enabled, for over-the-net viewing.

The only downside to the picture quality is the off colors. Though you get smooth, clear pictures, the colors are inaccurate. But if you’re strictly using the camera for surveillance, color fidelity shouldn’t matter too much, right?

The cam also comes with a built-in microphone which provides clear audio recording. It also has a plug for an external microphone so you can choose to attach one when you want maximum audio quality.

Cam Features

The Linksys wireless PTZ Internet camera comes with good pan, tilt, and zoom capabilities. What’s even better about it is that you can create position and which you can cycle at preset intervals or choose such options as “on-image pan tilt” which allows you to click on any point on the video and have the camera focus on that position.

Another cool feature on the Linksys wireless PTZ Internet camera is its motion-detector, which prompts the camera to record a short video clip every time it detects movement within its range, and send the clip to your email for notification.

Not all computer memory upgrades are the same.

Generally speaking, computer memory upgrades (not including Flash memory cards or USB drives) can be divided into two different types:

Type 1: Generic upgrades. These are made by a plethora of manufacturers and are made to a speed and form factor specification, such as a DDR-333 200 pin SO-DIMM, or a DDR2-667 240 pin DIMM. Generic upgrades are made without regard to the particular requirements of the computer they are being installed in. Generic upgrades are usually cheaper and supplied by 1000’s of resellers worldwide.

Type 2: System specific upgrades. (Also known as ‘branded’ memory). This is memory that is made to a particular speed and form factor specification, and further tested to function in particular brand / model computers and motherboards. The most well known manufacturer of system specific upgrades is Kingston.

In recent years other memory manufacturers have also chosen to compete in the branded memory market, such as Transcend, Corsair, A-data, and Patriot. All offer similar guarantees of compatibility, however Kingston is arguably the most trusted brand, especially amongst those who work in the IT sector. Kingston also have close relationships with the major OEM’s like IBM, such that technicians will service onsite Kingston memory products that have been installed in IBM computer systems.

If you purchase a system specific module(s) for your computer, Kingston will guarantee it to be compatible. System specific upgrades are generally a little more expensive than generic upgrades because the design is customized to meet the memory requirements of the computer system the module is designed for. Kingston also also tests the module in the end system using popular applications that people use every day (email clients, web browsers, etc), operating systems and the original equipment manufacturer’s own system diagnostic program.

So, let’s say you own a Dell Latitude D830 model laptop and you want to upgrade the memory. You have referred to your owners manual and you’ve figured out that your computer takes DDR2-667 (also known as PC2-5300) 200-pin SO-DIMMs. You could now just find the retailer with the cheapest DDR2-667 SO-DIMMs on the internet and duly purchase them. I see this as a lottery. Chances are you may be lucky and the modules may work. However, like many people who buy the cheapest memory they can find, and then end up purchasing the correct upgrade from RamCity, you may have problems with modules made using a lower quality manufacturing process. In many cases these people lost their money because their purchase came without any warranty as to compatibility and the reseller argued that their purchase was not faulty, just incompatible.

So, if you are in the market for a RAM upgrade, and want some peace of mind and reassurance that it is going to work the first time, be sure to ask your reseller if they sell system specific memory upgrades. Also check if they offer a guarantee that their modules will work in your computer, or happily refund your money in full.

People can often be put off from buying security camera systems because of concerns about the complexities of security camera system installation. Even though installing security camera systems can have its hassles, you can avoid most of them by the adequate planning described in this installation checklist.

Before you buy your Security Camera

Ensure you are buying the right security system for your property. If you are unsure then a paid professional can do a survey and advise you of the best suited equipment and solve any potential problems you may have.

Check your Power Source

One of the most common problems with security cameras is the lack of an appropriate power source. This problem is especially common in an outdoor security camera installation. It’s no very encouraging to walk outside to install your CCTV to then realize you can’t plug it in.

Know where your outlets are before you buy. If you know potential power problems up front, you can get good advice from sales representatives or even CCTV installers before you buy. Their expert suggestions may take you in an entirely different direction than you might have gone without it.

If access to a power source is a challenge to your CCTV installation, you have several options. You can have power outlets installed near where you plan to install your cameras. Alternately, you can run hidden wiring into an outlet inside your garage. Or you can opt for a camera that draws power from a plug-in battery pack.

Security Lighting

With any outdoor security camera system installation lighting is another important consideration. If you want to monitor an area at night, you must ensure the area has enough lighting for the camera to display images clearly. You can either do this by installing some outdoor floodlights, or you can choose a camera with low light ratings (known as lux), or even a camera with infrared capability.

Weather and Climate factors

A sturdy weather proof protective casing is an essential option for any outside security camera system installation.

Depending on the climate in your location, you may need to consider the temperature ranges your system will need to endure. Not many CCTV cameras can work in extreme temperatures in hot climates, or very low temperatures in cold climates. Make sure the system you choose to install will work all year round in your climate.

Cables or Wireless?

The final factor to preplan in any security camera installation is cables. Running cables from your camera to your control point can be the most time-consuming task for CCTV installers.

With the ever improving reliability of wireless camera systems, wiring may not be required. However, if you are planning to install wireless CCTV cameras, you still need to plan your installation beforehand.

The signal range of wireless cameras is normally adequate for most installations. Ranges do vary though and can be reduced by walls and obstacles between the receiver and the camera. Don’t be put off by the presence of walls or objects, just bear in mind the more objects there are, the shorter the distance can be between the receiver and the camera. You therefore need to plan beforehand what distances and what obstacles are in the path of the signal. If you are worried, go for wireless security systems with stronger signal strengths.

Ultimately, installing security cameras is well within the ability of a competent do-it-yourselfer. Complications arise mainly when a buyer brings home a system that doesn’t fit their situation and then struggles to make it fit. If you determine your needs ahead of time and get competent advice, your CCTV installation should be manageable, whether you do it yourself, or use professional CCTV installers.

Some testimonials may talk about the limitations of the software. In any event, testimonials are helpful because it will highlight software’s strengths and weaknesses. Product reviews are the opinions of professionals such as programmers, punters, tipsters, and statisticians. This is equally helpful because their opinions are highly scientific and objective. You must strike a delicate balance between user testimonials and software reviews to have a definitive opinion on what software you should use.

Look For Screenshots and Demos

The rule of thumb in choosing all kinds of software is this: make sure that that it is easy to use. Because, after all, predicting the winning horse all boils down to statistics. So you can expect the horse racing software to show you all kinds of numbers such as odds, probabilities, race position, betting banks, and profits. The good ones will see to it that these numbers are properly labeled and highlighted. When you visit websites that sell horse racing software, make sure that there are screenshots of its interface.

If you base your bets solely on your gut, chances are you would lose. That is why you need horse racing software so that your bets will be more precise and scientific. When the software works, you’ll be assured that your bets will always be on the winning horse.

The high tech, elaborate cell phones that many people use in the modern world are a far cry from the first mobile phones. Yet if it was not for these earlier versions of mobile communication devices, we would not have the option of cell phones and the many phone feature that we take for granted.

The development of talking on radio waves started with Reginald Fessenden, a Canadian inventor who began working with Thomas Edison in 1886. On December 23, 1900, Fessenden successively transmitted speech approximately 1.6 kilometers, the very first audio radio transmission. By December 21, 1906, the inventor successfully demonstrated his new alternator transmitter, showing its utility for point-to point wireless telephony. He also demonstrated his interconnection of his stations to the wire telephone network. Fessenden made the first two-way transatlantic radio transmission in this same year.

Soon after Fessenden’s demonstrations, the first wireless phone was patented in 1908. The patent was given to Nathan B. Stubblefield of Murray, Kentucky who was an inventor as well as the founder of Teleph-on-delgreen Industrial School. He applied the patent to a “cave radio” telephone which was a more primitive design of wireless telephones.

During World War II, radio telephony grew in popularity as the choice of communication in the military. Towards the end of the war in 1945, the zero generation of mobile phones were introduced. These phones worked off a single, powerful base station and covered a wide area. They operated by monopolizing one channel in that particular area while the phones were in use. In 1947, Bell Lab engineers at AT&T invented the first cells for mobile phone base stations and continued to develop these cells well into the 1960s.

On April 3, 1973, Martin Cooper, who was a researcher and executive at Motorola made the first call on a handheld mobile phone. Sixteen years later, on May 1, 1979, a United States patent was given to Charles A. Gladden and Martin H. Parelman, both of Las Vegas, Nevada. If you carefully read the patent, these two inventors were beginning to combine all the elements that led to the next development in radio telephony, the Analog Cellular Telephone. In that same year, NTT of Japan launched the first commercial citywide cellular network.

In 1983, the Motorola DynaTAC was the first approved mobile phone by the FCC. In, 1984, basing their work on the 1979 patent of Gladden and Parelman, Bell Labs developed the modern cellular technology that involves the utility of cell sites, each providing service to an individual cell. At this same time, fully automated cellular networks were introduced.

In 1991, the first modern network technology was introduced by Radiolinja in Finland, leading to the Nordic Mobile Telephone system going online. This was the first instance of competition between cell phone providers as this company set itself up against Telecom Finland. This development also led to an increase in mobile phone usage in northern Europe.

As the years have passed, cell phone companies have become booming businesses as the demand for these devices continues to increase at an astronomical rate. If not for the efforts of the early inventors and engineers, this technology would have not been possible. We as a society on the whole owe these men and women our thanks.

Since the terrifying events of September 11, 2001, there had been pressure on cell phone providers to integrate some kind of GPS tracking system so that a suspicious cell phone call could be traced to the location of the caller. At the end of 2005 all cell phone service providers were mandated to update their equipment so that they would have the capabilities to trace any cell phone calls within 100 meters of the location where the phone was being used. Instead of incurring the extra expense of restructuring their whole tower network, these companies decided to put the GPS technology in place in the cell phones themselves. These built-in tracking devices are not available for personal use, however. Most of these systems require assistance from a wireless network and are only put into use if a 911 call is made or if it is a law enforcement matter.

There are certain models of cell phones that have the GPS feature included on them. When deciding to purchase one of these phones you should keep in mind that it is illegal to track someone without his knowledge as this is an invasion of his privacy. You must have the cell phone subscriber’s permission before you can enable a GPS device. In matters of the person’s personal safety, however, a judge can waive the need for this permission, such as in the case of an elderly person who is known to “wander” off and become lost and disoriented. A GPS tracking system could be the difference between life and death and would probably be allowed in this situation. This law is also not in effect when you are tracking your children, as long as the cell phone is in your name. For children over eighteen years of age, however, it is probably is not a good idea.

As well as tracking seniors and children, there may be times when you need to be tracked yourself. If you are an avid outdoorsman who enjoys going off into the wilderness alone, it is a good idea to give your spouse or a close friend permission to track your cell phone in case of an emergency situation where you may be alone and miles away from any help. This is also a good idea if you are traveling in bad weather, especially if your vehicle does not have a GPS system of its own. In these cases, it is better to take the extra precautions than to suffer for it later.

Some of the companies that offer GPS tracking are T-Mobil and Sprint. Some of the cell phones available with this feature that are on the market include Motorolla, iDEN, and Blackberry. Disney Mobile and Wherify Wireless both offer their own versions of GPS cell phones. Most of these companies have a call center and a Web site that enables you to pinpoint a person’s location easily.

Again, GPS tracking devices and cell phones are wonderful tools to use to track someone when it involves a safety issue. Using it for the wrong reasons, however, is illegal as well as unconstitutional. You should use your best judgment when deciding to make use of a GPS system.
