Standard Notions of Surveillance Networks
Before you install surveillance equipment into your home, it is important that you understand the core concepts of remote observation. Recording visual data plays a vital role in enforcing security on the premises. A top-notch system must thus be implemented and maintained by the guard company. Here are four definitions that you can use in preparation for selecting a business to watch over you.
CCTV - Closed Circuit Television is made up of an array of cameras that transmit visual data to a central location. This data can only be seen by devices on the circuit and so provides a more secure visual link for the owners.
Wired/Wireless - Closed circuit television networks come in two different operations. A wired system uses a series of wires to transmit the data from the location to the control station. However, this requires a lot of money and time to install a device and its wires in the selected areas. Wireless television transmits its data over radio frequencies, however, there is the possibility that the frequencies may be tapped into and the information used to spy on you in return.
DVR - A Digital Video Recorder can be used in conjunction with closed circuit television to preserve surveillance data in mass storage. This allows video data to be preserved and transferred with relative ease from point to point.
Hidden Camera - Also known as a nanny cam or a spy cam, this is a device which is usually inconspicuously placed or concealed. This adds an extra layer of security to your home, since potential vandals may not notice and destroy the device.
