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 be 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 by 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. Specially developed embedded DVRs have in built features like impact resistance, shock & and 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 automobile. It can also provide the driver with a view of the road andor 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 yet to be realized and it may not be a surprise to see them used by everyday people for everyday living..
Free Satellite TV
Television that comes through communication satellites is referred to as satellite television. Digital signals are beamed from satellites to users and these are of three primary types: signals received directly by the viewer, that received by local television affiliates for distribution, or reception by headends for distribution through cables.
Of the many satellite TV systems Dish Network and Direct TV are the main players. Both offer "free" satellite TV systems for four rooms with a bouquet of other services like over 250 program selections.
What is free to a first time user is the equipment needed to capture the TV signals. Otherwise one has to pay for viewing and choose a package that suits personal requirements. Many companies and online sites offer free services and enticing satellite TV deals but most of these are scams.
Beware of traps and believe in the maxim "nothing in life is for free."
