Spy Gadgets For Fun and Security

As a kid, were you intrigued by the enticing ads in your comic books? You know the ones I mean, gadgets that would enable you to see around corners, or listen to conversations right through walls? We could not resist the appeal, especially since they only cost a dollar or two. Before we knew it, we'd be sealing our hopes, as well as our money in an envelope, eagerly awaiting the day our special spy toys would arrive in our mailbox.

Since those days, we've enjoyed thriller spy movies, and endless crime shows on television, where investigators employ every trick in the book to solve the latest case. We are amazed by the speed and accuracy of intranet lab work, digital enhancements, and computer imaging. As cutting edge as all of this is, there are some techniques that have been around a long, long time.

Did you ever try using invisible ink when you were a child? This was a fun thing to do that rated right up there with magic and card tricks. By mixing up a special ink of milk, lemon juice, or sugar water, your secret message would only be visible when the paper was heated. Invisible ink is still used today, but instead of exposing the message to heat, a prescribed wavelength of ultraviolet light is used.

We all have a yard of spy satellites that circle the globe gathering information from high above the earth. Before satellites, airplanes were used for intelligence missions in World War II, which enabled military leaders the chance to monitor allied and enemy movements. It is astounding to think that even way back in the American Civil War, observation balloons were floated by both sides in the conflict, to observe their own, and enemy troop locations.

Movies are ripe with many measures taken by spies as they alter their appearance in order not to be recognized. We've seen hair being cut and dyed, women dressing as men, and in one instance in 1754, Chevalier d'Eon de Beaumont was sent to St. Louis. Petersburg posing as Mademoiselle Lia de Beaumont. As improbable as it may seem, the ploy worked, and Tsarina Elisabeth was persuaded to forgo a strategy with Britain, and side with Austria and France instead.

In some old films we see bandages being slowly unwrapped on a surgically rearranged face. Or in some flicks, complete latex masks with hair attached, completely change the facial appearance of a character. Today, with the use of facial recognition software, spies may have to forgo a mask or simple change of attire, and revert to plastic surgery once again.

Today, digital technology has resulated in devices that are so small and effective that the modern day spy can literally mostly on gathering information remotely. Without the agent absolutely has to, there is no need for elaborate disguises. Devices can simply be put in place and activated, which means that we can all become spies if need be.

Just about any everyday item can be used as a camera. A light fixture, a calculator, or a smoke detector can have a tiny camera inserted into it, so that photos can be taken without the slightest hint of what's going on. Spy Cams can help protect your business and your home. They can also keep people honest. Just knowing that areas are being monitored makes us all safer.

There are devices that can be installed on your computer to monitor what's being watched and messages that are being sent and received. The SIM card can be removed from a cell phone and inserted into a special device that displays all the deleted text messages. All these items have become completely affordable, easy to obtain, and use.

A really exciting development is the GPS tracker. With a personal tracker you can monitor your children, ensuring that they are safe at all times, and knowing their location if they suddenly need help. Then there is another version that you can use for your vehicles. Car theft is rampant and on the rise. If one of your cars is stolen, this device will greatly aid the police in returning your property to you.

This time, however, you will not need to consult the back pages of your comic book. Today, with just a few clicks of your mouse, you can access spy shop catalogs online, and order some neat spy gadgets conveniently from your computer.

Embedded DVR

In most surveillance operations using a DVR, the commonly used method is to link the DVR card to a computer containing the software. This has serious limitations in the event of a virus attack or power failure, because the surveillance system could have thrown off gear. In order to overcome these problems, a new type of DVR called the "embedded DVR" has been launched.

The embedded DVR works with very little or no help from the computer. It is a plug and play meaning that installation is very easy and recording can start as soon as the device is installed. Embedded DVRs can support 4-16 cameras, and a television screen can be added for viewing live pictures. Embedded DVRs provide all the features that come with computer based DVR systems including network support options that allow you to share the recorded data. The motion of the camera can be controlled based on motion and playback and search option are also available.

Embedded DVRs can be programmed to record at specific times. With an alarm facility available, fast detection of any intrusion can be detected. On integration with a web server, remote audio / video monitoring and recording is facilitated. Data storage is usually in MPEG format. If there is a problem with storage, a back up plan is activated where the data is written onto CD disks. Embedded DVRs also have remote storage facility meaning storage of information can be done at a location away from where the input device is located. This can minimize data pilferage or theft.

Embedded DVRs are now used extensively in the transport sector. Specifically developed embedded DVRs have in built features like impact resistance, shock & vibration resistance are now found in trucks, school and city buses, airport shuttles, cars, taxis, etc. These DVRs are compact and take inputs provided by camera located in different parts of the vehicle. It can also provide the driver with a view of the road and / or passengers at all times. In such a system, the storage device is often a replaceable hard disk drive. In some cases, a USB mobile hard disk enclosure is also provided. Use of DVRs in public and private transport devices can increase the security of passengers and cargo.

With enhanced emphasis on security, embedded DVRs have become an irreplaceable component of industrial and corporate security systems. In the near future, the embedded DVRs may find new applications many areas. The full potentials of this device are still to be realized and it may not be a surprise to see them used by everyday people for everyday living.

All About Your 3G Internet Service

In the technology circle, there is much hue and cry about 3G internet services. It is a known fact to everyone that 3G stands for "3rd Generation", but very few are aware of this technology from its core. Basically, it's an initiative taken by the International Telecommunication Union to create a global wireless standard for mobile internet access. However, it requires a minimum mobile internet access speed which is comparable to DSL (Digital Subscriber Line) internet speed. To meet the technology standards, there needs to be high-volume voice services.

Unlike its predecessor 2G (2nd Generation) technology, which was discovered around voice applications including talking, call-waiting and voicemail, 3G technology emphasizes on internet and multimedia based applications that facilitate web browsing, music downloads, video conferencing etc. However, to access 3G network, your device need to support an information transfer rate of at least 200 Kbit / s. With the increased demand for high-speed internet services, the popularity of 3G is also surmounting. The technology has multiple benefits to offer, some of which are discussed below:

High-speed Internet on the Go: Before the advent of this technology, it was almost a dream to get access to high-speed internet on the go. Modern developments in mobile technology coupled with 3G has created great opportunities for users to surf internet at a blazing fast speed, even while they are traveling.

Reaches Remotest Corners: It's easy to find 3G access at places where wired connectivity is difficult to install. This helps minimize the gap in internet access in rural areas or areas with limited connectivity. The speed sometimes exceeds the speed of dial-up internet services.

Affordability: 3G standards benefited the rural people to a great extent. While it's expensive to set up wired connections at homes, the wireless internet costs less and offer better speed to the users. With the development of this telecommunication technology, users can now get high-speed connectivity even on their mobile devices.

Multimedia Usage: Both corporate and personal consumers benefit from the service as it facilitates the use of diverse multimedia applications and enhancements the wireless internet experience. It enables real-time video conferencing, music download at a faster speed, uploading and downloading files at a speed that equals to wired broadband services.

Stay Entertainment: Internet offers multiple ways to keep the users entertained. For lightning fast internet speed and seamless network availability, users can enjoy online gaming, listen to their favorite music or watch movies online with their 3G internet connection.

Although, 3G internet technology is getting momentum both in urban and rural areas, there are still some places where this technology is not as effective as metropolitan cities like New York and San Diego. While telecommunication experts are hopeful to enhance the reach of both 3G and 4G (4th Generation) networks and make the services more affordable for the users, the increased traffic and the usage of mobile devices are the two main issues of concern for the tech experts. Moreover, to sustain a balance in the environment, there needs to take more precautions, as wireless rays often cause harmful radiation, which have adverse impact on the environment.
