There are several key differences between DVRs and VCRs that result in significant advantages for DVR users. The most notable difference between the DVR and VCR is the medium used for recording the video images. VCRs record images on magnetic tapes, while digital systems use HD drives, DATs or DVDs. This differentiation has significant implications in terms of the video image quality, speed of information retrieval, image transmission speed, and remote monitoring capabilities. Digital video systems using DVRs can be accessed over LAN, intranets, and the Internet. This permits security personnel to monitor remote sites across the street, town, or locations hundreds or thousands miles away. Using an Internet browser or other application software on any PC or laptop allows security with personnel or corporate management to view recorded digital video images at a secure IP (Internet protocol) address from anywhere in the world.
Security systems using Smart DVR can play a major role in alarm verification. Having the ability to perform video assessment from remote locations means the system can be used to prevent false alarm responses by security and police personnel. The ability to remotely and instantly view the alarm site means that if a review of the video images indicates there are no intruders, a false alarm can be declared and no law enforcement personnel need be notified. The digital video images are stored on HD drives similar to those used in the PC industry and have storage capacities measured in hundreds of megabytes or gigabytes, providing a low cost storage media for the compressed video files. Small and medium-size systems use several HD drives, while large enterprise systems use a large number of HD drives. These HD drives are synchronized and shared to store images from many video cameras reliably, and available for rapid access by the user. The DVR has high reliability as compared to the VCR recorder. The DVD provides higher image quality as compared to its VCR predecessor. The rearview mirror camera images can be downloaded to an external medium. The Zip file/disk or an email over the Internet is the easiest for the DVR.The technology difference between analog and digital recording is that the analog tape recorder incorporates a magnetic field to align the magnetic particles on the surface of the VHS tape to correspond to the video signal image. In contrast, the DVR converts the analog signal into a digital signal of ones and zeros, compresses this digital signal, and then stores it on the magnetic DVR HD drive, DVD, or DAT. The combination of affordable image compression technologies and large capacity HD drives has made the development of the DVR a reality. Although HD DVR recording like VHS still uses a magnetic recording medium, the digital nature of the data insures that all retrieved footage is an identical copy of the originally recorded signals. Standard DVRs have some shortcomings when used in mid-range and large size Enterprise systems. Since video inputs are local to the DVR, and a smart rearview mirror source has to be wired at the location of the DVR, this results in a significant investment in cable.More information at http://www.jimilab.com/.

Just like software vendors, GPS manufacturers find bugs and add enhancements to their products. New versions of a GPS receiver’s operating system can be upgraded through the receiver’s firmware (the updatable, read-only software that’s embedded in a hardware device).
Check that your GPS receiver’s firmware is current every few months or so, especially if your receiver is a newly released model. GPS manufacturers offer free downloads of firmware upgrades on their Web sites, and these bug-fixes or new features can definitely make your GPS receiver perform better.
To upgrade your firmware
Check the current version of your GPS receiver firmware.
Sometimes this is displayed when the GPS receiver is turned on, or it might be shown on an information page. Consult your user’s guide or the manufacturer’s website for specific instructions on how to get this information for your model.
Visit the manufacturers’s Web site and go to the software updates section.
Here are the URLs of the major GPS manufacturers:
- Garmin: www.garmin.com
If you have a Garmin GPS receiver, you can sign up for automatic e-mail notification of firmware upgrades at the Garmin Web site. I expect other GPS manufacturers to start offering this service.
Lowrance: www.lowrance.com
Magellan: www.magellangps.com
Find your GPS receiver model and check its manufacturer’s website for the latest firmware version.
If your firmware is older than the current version on the website, follow the online instructions to download the firmware installer. Usually, the higher the version number, the more recent the firmware version. Make sure that the firmware installer you download is for your GPS receiver model. If you upload firmware designed for a different model, plan on the GPS receiver not working until you load the proper firmware.
Follow the installation instructions that come with the downloaded file.
Usually firmware installation files come in two forms:
A standalone program that runs on your computer, connects to the GPS receiver, and sends the upgraded firmware to the receiver. You need to have a PC interface cable attached to both the computer and the GPS receiver.
A special file that you copy to a memory card. When the GPS receiver starts, it searches the card to see whether a firmware upgrade is present. If it is, the receiver uploads the upgrade. After the upgrade is successful, you can erase the firmware upgrade file from the memory card.
Upgrading a GPS receiver’s firmware is pretty easy; not too much can go wrong. About the only thing that can get you in trouble is if the GPS receiver’s batteries die midway through a firmware upload. A firmware upgrade usually only takes a few minutes to complete, but make sure that your batteries aren’t running on empty before you start.
Some firmware update software works only on COM ports 1 through 4. If you’re using a USB adapter, (which is usually set to COM port 5 or higher) and are having problems connecting to the GPS receiver, try reassigning the existing COM ports to numbers higher than the USB adapter’s port; then set the adapter’s port number to 1. Refer to online Windows help (choose Start➪ Help) and perform a search for device manager to get more information on changing device settings.

In these instances, all the maps and GPS receivers must use the same datum. If the datums are different, the location ends up in two different physical places even though the map coordinates are exactly the same. This is a common mistake: GPS Vehicle Tracking Device use the WGS 84 datum by default, and USGS topographic maps use the NAD 27 datum. If you mix the datums, your location can be off by up to 200 meters (roughly 200 yards, if you’re metrically challenged). Utilities can convert coordinates from one datum to another (some are described in Chapter 11) but it’s easier just to get all the datums on the same map. A GPS receiver alarm can transmit a tone or display a message when you approach a location that you specify. This feature can be especially useful when you’re trying to find a place and visibility is limited by darkness or inclement weather — or you’re busy doing something else and aren’t looking at the GPS Mini Tracker screen. Every GPS Mini Trackerhas an information page that shows waypoints and tracks. The page is a simple map that plots travel and locations. It doesn’t show roads, geographic features, or man-made structures. Figure 3-4 shows two GPS receiver screens: simple location plotting on the left, and a more sophisticated, uploaded map on the right. GPS receivers that display maps use proprietary map data from the manufacturer. That means you can’t load another manufacturer’s or software company’s maps into a GPS receiver. However, clever hackers reverse-engineered JIMI’s map format. Programs on the Internet can create and upload your own maps to JIMI Vehicle GPS Locator; GPS mapper is popular. A handheld GPS receiver’s screen is only several inches across. The limitations of such a small display certainly don’t make the devices replacements for traditional paper maps. All GPS receivers can tell you which direction you’re heading — that is, as long as you’re moving. The minute you stop, the receiver stops acting as a compass. To address this limitation, some GPS receivers incorporate an electronic compass that doesn’t rely on the GPS satellites.GPS tracking devices you can go to http://www.jimilab.com/products/gt350-mini-personal-gps-tracker.html.

IN WHICH you are introduced to facts and concepts relating to the NAVSTAR Global Positioning System and have your first experience using aGPS Tracking Device.A sports club in Seattle decided to mount a hunting expedition. They employed a guide who came well recommended, and whose own views of his abilities were greater still. Unfortunately, after two days, the group was completely, totally lost. “You told me you were the best guide in the State of Washington,” fumed the person responsible for hiring the guide. “I am, Iam” claimed the man defensively. “But just now I think we’re in Canada.” Stories like the one above should be told now (if at all), before they cease to be plausible. Actually, even at present, given the right equipment and a map of the general area, you could be led blindfolded to any spot in the great out-of-doors and determine exactly where you were. This happy capability is due to some ingenious electronics and a dozen billion dollars 1 spent by the U.S. government. I refer to NAVSTAR (NAVigation System with Time And Ranging; informally the “Navigation Star”)–a constellation of from 24 to 32 satellites orbiting the Earth, broadcasting data that allows users on or near the Earth to determine their spatial positions. The more general term in the United States for such an entity is “Global Positioning System” or “GPS.” The Russians have such a navigation system as well, which they call GLONASS (GLObal NAvigation Satellite System). (One might reflect that, for some purposes, the cold war lasted just long enough.) A more general, recent acronym for such systems is GNSS, standing for Global Navigation Satellite Systems. In the western world, GPS usually implies NAVSTAR, so I will use the two designations interchangeably in this text.
With GPS, the earth’s surface becomes the digitizer board; the tracking device antenna becomes the puck. This approach inverts the entire traditional process of GIS data collection: spatial data come directly from the environment and the map becomes a document of output rather than input. At sea, or flying over unlit bodies of land at night, captains and pilots used methods that provided absolute coordinates. One’s position, within a few miles, can be found by “shooting the stars” for a short time with devices such as sextants or octants.Tracking devices for people , then, gives people an easy method for both assigning and using absolute coordinates. Now, humans can know their positions (i.e., the coordinates that specify where they are); combined with map and/or GIS data they can know their locations (i.e., where they are with respect to objects around them). So the GPS concept–finding an earthly position from bodies in space–is not an entirely new idea. But the ability to do so during the day, almost regardless of weather, with high accuracy and almost instantaneously, makes a major qualitative difference. As a parallel, consider that a human can move by foot or by jet plane. They are both methods of locomotion, but there the similarity ends.More information at http://www.jimilab.com/.
