Security is a priority for all businesses, and neglecting it creates an unsafe working environment that is hardly conducive to productivity. There are many advanced video monitoring devices that can be implemented into almost any business setting for security purposes. A modern system can eliminate the need for hiring a large security staff.
The latest video technology for security today is wireless video surveillance. This allows the business owner to monitor their commercial property from anywhere. Their laptop or desktop computer serves as the monitor for the camera that can be controlled from the keyboard or with the mouse. Some devices allow business owners to secure their property while at home or on vacation.
Networking video uses both private and public internet resources. It allows authorized customers viewing access to real time video anywhere by means of a video feeder, provided they have proper security credentials. Private networking is usually sourced by Ethernet or LAN. In the last several years video equipment has increased in both sales and capability.
Networking Video Management Systems (NVMS) are suitable for both on and off site monitoring and can make the feed accessible from multiple stations. Enterprise systems may add extra features to monitor, record, and analyze functionality and deliver information in an accurate and timely manner. When these features are present in the smaller (NVR) systems they offer more productive, and substantially advantageous functionality features.
In some instances a Network video system can be of more use than the DVR-based system. They tend to be more cost efficient, which is always a factor to consider when choosing a system. They are usually categorized into four main points of interest: Lower cost of ownership, Internet Protocol Technology, Transmission and Storage capabilities, and reduced Bandwidth compression, for Improved Management Capabilities. It is essential that the provider is not only knowledgeable in technical sales, but also in security integrated systems.
With the vast amount of security technology on the market today, there is no need for any business to be without protection. There is definitely something to fit every budget. Small business owners can benefit just as much as commercial business owners. The need to save money and secure business investments are part of every company, regardless of industry or size.
Keep in mind that the most expensive system is not necessarily the best, nor should one settle for the least expensive system. An audio/video professional can help you choose the best system for your property and make the installation process quick and easy.
So-called nanny cams are also part of the video technology for security systems that are widely used. Daycare owners are able to spot negligence and accidents as they happen, without letting safety issues get out of control. Hospitals use these video surveillance cameras to ensure patient safety and to provide 24 hour monitoring of on the ground premises. Jailhouses, prisons, and work release centers use highly integrated security systems that provides continuous feedback from several video feeders. Although these more advanced video security systems can feel expensive, they pay for themselves when thefts, accidents, and fires are prevented.

Bluetooth Technology
BLUETOOTH
The convergence of computing and communications has led to the development of Bluetooth technology. Taking the short-range wireless data usage to a new level, this technology is predicted to dominate both the home and business markets.
Now no more complicated tangle of cables and wires are required to connect electronic equipment. A revolutionary technology called Bluetooth allows for the replacement of the cumbersome cables used today to connect a laptop to a cellular phone with one universal low-cost, short-range radio link. Printers, PDAs, desktops, fax machines, keyboards, and virtually any other digital device can be a part of the Bluetooth system. Bluetooth is faster than mobile phones, including the upcoming third-generation, or 3G, high-speed wireless data transmission.
The technology
Bluetooth is a universal radio interface in the 2.45GHz ISM frequency band to function on a worldwide basis.
The interface consists of hardware using ICs, a radio frequency chip, and a baseband chip. These parts work together to put a radio signal into the air that can communicate to another chipset imbedded in other product. This makes it easier to do everything, from networking different types of computers to transferring data between digital telephones.Bluetooth can transmit through solid, non-metal objects. Its nominal link range is from 10 cm to 10 m, which can be extended to 100 m by increasing the transmit power.
Designed to operate in a noisy radio frequency environment, the Bluetooth radio uses a fast acknowledgement and frequency hopping scheme to make the link robust. Bluetooth radio modules avoid interference from other signals by hopping to a new frequency after transmitting or receiving packet.Short range and fast hopping limit the impact of domestic and professional microwave ovens. Use of forward error correction (FEC) limits the impact of random noise on long-distance links. The encoding is optimized for an uncoordinated environment.
The Bluetooth baseband protocol is a combination of circuit and packet switching. Slots can be reserved for synchronous packets. Each packet is transmitted in a different hop frequency. A packet nominally covers a single slot, but can be extended to cover up to five slots.
The technology supports both isochronous and asynchronous services; easy integration of TCP/IP for networking. It can support an asynchronous data channel, up to three simultaneous synchronous voice channels, or a channel which simultaneously supports asynchronous data and synchronous voice. Each voice channel supports 64kbps synchronous (voice) link. The asynchronous channel can support an asymmetric link of maximally 721 kbps in either direction, while permitting 57.6 kbps in the return direction, or a 432.6kbps symmetric link.

How it works
A Bluetooth system comprises a radio unit, a link controller, link manager, and software.
The Bluetooth radio interface is based on a nominal antenna power of 0 dBm . The air interface complies with the FCC rules for the ISM band at power levels up to 0 dBm. Spectrum spreading facilitates optional operation at power levels up to 100 mW worldwide. It is accomplished by frequency hopping in 79 hops displaced by 1 MHz, starting at 2.402 GHz and stopping at 2.480 Hz. The bandwidth is controlled by an internal software switch. The maximum frequency hopping rate is 1,600 hops/sec.
The baseband describes the specifications of the digital signal processing part of the hardware the Bluetooth link controller, which carries out the baseband protocols and other low-level link routines.
A piconet is a group of two to eight devices connected via Bluetooth technology. Before any connections in a piconet are created, all devices are in standby mode. In this mode, an unconnected unit periodically listens for messages every 1.28 seconds. Each time a device wakes up, it listens on a set of 32 hop frequencies defined for that unit. The number of hop frequencies is 32 for most countries, except Japan, Spain, and France.
Any of the devices becomes the master by initiating the connection procedure.
Technology developers
Bluetooth technology is being developed through the combined contributions of the members of the Bluetooth Special Interest Group. Intel brings architectural knowledge, advanced silicon technology, manufacturing expertise, and software components to the group. Ericsson contributed the basic radio technology. Nokia contributed the radio technology and mobile handset software. IBM and Toshiba developed a common specification for integrating Bluetooth technology into mobile devices. Microsoft, Lucent technologies, Motorola, and 3Com have signed on as primary Bluetooth promoters. Many smaller companies worldwide have also signed up for royalty-free rights to the emerging standard.
The final word
Bluetooth technology is being developed as an open specification, and will be licensed royalty-free to all companies who sign up to become members of the Bluetooth initiative. This will allow a quick proliferation of the technology through a wide-range of mobile products and devices. Products integrated with Bluetooth radios are expected to hit the market shortly.
