The Global Positioning System (GPS) is the only fully functional Global Navigation Satellite System (GNSS) which is a satellite based navigational technology. GPS is widely known as automobile tracking system that allows the firms with large fleets of vehicles spread across a huge territory to keep a track of the whereabouts of their vehicles.

GPS is very advantageous and is considered as a better fleet tracking system. This is because the connection between GPS satellites and GPS fleet tracking receivers remains unbroken

irrespective of the presence of skyscrapers, high disturbance or high interference.

There are several benefits attached to GPS fleet tracking system and that is why, several companies opt for GPS fleet tracking system to regulate an employee tracking system based on time cards and driver-written mileage records. The vehicle’s travel summary can be stored directly into a computer using this automobile tracking system. This system allows determining the time that each of the drivers takes. This helps the firm to keep a check on drivers’ performance and service.

At the time of emergency such as accident, carjacking etc., people can use the panic button of GPS vehicle tracking system. Once the button is pressed, an operator at the nearest GPS carrier will automatically start listening the entire incidence. The GPS automobile tracking system is a boon in case of a complete break down of the vehicle.

The most common use of GPS vehicle tracking system is in a condition where the vehicle is stolen. In such situation, the victims should inform their GPS carriers about the entire scene. The GPS carriers will immediately trace the vehicle’s location, its racing speed and inform the police to complete the recovery formalities for their users.

Manufacturers are choosing to label their digital cameras with the total (optical x digital) zoom which is confusing the consumers. Total zoom is actually the combination of Optical Zoom and Digital Zoom.

In this article, we discuss about the optical zoom vis-à-vis digital zoom. Read on.

Optical zoom uses the lens (optics) of the camera to bring the subject closer.

On the other hand, digital zoom is not exactly zooming. Digital zoom enlarges a portion of the image, ‘stimulating’ optical zoom.

Optical zoom doesn’t affect the picture quality whereas, when a picture is enlarged by digital zoom, the image loses its quality.

 Higher optical zoom is beneficial for your camcorder. This is because; a higher optical zoom will produce clearer pictures. The pictures are enlarged by the actual lenses. This allows you to capture a video from farther distance effectively, without affecting the quality of the pictures.

On the other hand, a digital zoom enlarges a picture, but reduces the overall picture quality. The picture is artificially enlarged by the digital zoom (hence the name “digital”).

However, we should not strictly ignore digital zoom. It is perhaps an inevitable part of all digital cameras. By zooming digitally in camera, you get to see what your subject is doing and thus can capture the shot at the right moment.
