Each year sees the launch of numerous video surveillance cameras. Each being designed specifically to bring functionality, plus a plethora of new features to users worldwide. This year won't be any exception, with buyers hungry for the release of the newest options in video surveillance systems. The technological advancements of this new breed of cameras, including; wireless, multiplexers and DVR's, is creating a buzz throughout the industry.
The aim of this article is to look at the many aspects of video surveillance, and the impact these new systems will have on a world wide audience.
Video Surveillance: The Wireless Generation
Like many of the surveillance systems before, there has always been a strategic lead up to the launch of new surveillance equipment. Where the leading companies such as Pelco, Sony, Panasonic and Toshiba fight “tooth and nail” to get ahead in the race to dominate the market.
Wireless technology was introduced back in 2005, at a technology conference in Japan. Since it's genesis, wireless surveillance systems have increased in popularity, and seem to be the first choice in many homes. This is largely due to the ease in which the system can be implemented and administered.
Another benefit of wireless security is the ability to function anywhere, plus giving the system a higher secrecy level due to the exclusion of any wires. Many also come equipped with with a full range of movement e.g. tilt, pan and zoom. The top of the range systems if used by linking to a computer, feature MPEG-4 for high quality images and frame rates.
Multiplexing
Hand in hand with the video surveillance system comes the use of “multiplexers.” These devices allow multiple signals to share one resource. Multiplexers usually require a demultiplexer. This breaks the multiple data streams back into a lower rate stream of data.
So what this basically means in relation to surveillance cameras is that multiplexers can enable the system to send back a live stream, while also recording other streams ready for video playback.
Digital Video Recorders
Any good surveillance system needs a DVR to enable the user to record the data streams sent by the cameras themselves. There are many systems on the market, some come equipped with high quality hard disk recording and a multiplexer built in. So in monetary terms these systems can cost a lot less then a traditional VCR and multiplexer combo.
As you can probably tell by now, these are some of the reasons why the new breed of video surveillance cameras have received so much attention. With advancements in technology increasing almost daily, these systems will continue to be a source of security and peace of mind for years to come.
