當(dāng)前，許多領(lǐng)域都正在發(fā)展無線基礎(chǔ)設(shè)施。首先，相較于傳統(tǒng)的挖掘和鋪設(shè)線纜，它減少了基礎(chǔ)設(shè)施的成本，這在目前的經(jīng)濟環(huán)境中無疑是非常流行的。第二，無線基礎(chǔ)設(shè)施提供的聯(lián)網(wǎng)在文化領(lǐng)域有重要意義，在某些情況下，這甚至是唯一的選擇，比如城市的中心和歷史遺跡，這些地方無需再挖開路面。第三，無線技術(shù)能夠用于臨時的視頻監(jiān)控工程，這種靈活度是有線監(jiān)控方案無法提供的。在當(dāng)前經(jīng)濟緊縮的情況下，隨時移動攝像機到你需要用到它們的地方，是比買一個新的攝像機更有吸引力的選擇。 最后，最適合使用無線基礎(chǔ)設(shè)施的終端用戶產(chǎn)業(yè)是城市監(jiān)控，它恰恰是視頻監(jiān)控成長最快的垂直行業(yè)。事實上，最近城市監(jiān)控市場的增長潛力被海康威視的公告點亮，?？低暿且粋€以中國為市場基礎(chǔ)的視頻監(jiān)控設(shè)備供應(yīng)商，它已經(jīng)被指定為中國重慶一個價值8億美元的平安城市項目的總承包商。
在其他地區(qū)，如中東，無線基礎(chǔ)設(shè)施也被用來把監(jiān)控視頻實時地從警車傳送到指揮中心。這種把移動和固定位置相結(jié)合的方式十分有潛力，它可以提高對犯罪偵測和預(yù)防，使用該技術(shù)可以為警察機關(guān)提供更準確的情報。
那么，還有什么能減緩無線視頻監(jiān)控的成長呢?根據(jù)IMSResearch的研究，主要存在的問題，是系統(tǒng)集成商安裝無線視頻監(jiān)控所要具備的無線知識和技能。然而，由于城市監(jiān)控中的機遇不斷增加，越來越多的集成商將掌握無線技術(shù)，而且看起來在未來幾年，無線監(jiān)控將會是視頻監(jiān)控行業(yè)的主要增長領(lǐng)域。

City Surveillance Looks to Wireless Video
Wireless infrastructure has a number of things going for it right now. Firstly, it reduces the cost of infrastructure when compared with the traditional trenching and laying of cable, which in the current economic environment is unsurprisingly popular. Secondly, wireless infrastructure offers networking in areas of cultural significance, such as city centres and historic sites, without the need to dig up roads – in some cases, it is the only option. Thirdly, wireless technology can be used in temporary video surveillance installations to provide a degree of flexibility that a wired solution just cannot offer. In these days of austerity, moving cameras when and where you need them is a more attractive option than buying new cameras.Finally, the end-user industry that suits wireless infrastructure best is city surveillance (municipalities) which happens to be the fastest growing vertical market for video surveillance. In fact, the growth potential for the city surveillance market was highlighted recently by the announcement that HikVision, a China-based video surveillance equipment manufacturer, has been appointed general contractor on an $800 million safe city project in Chongqing, China.
In other regions, such as the Middle East, wireless infrastructure is also being used to stream video surveillance live from police vehicles to command centres. This integration between mobile and fixed locations has the potential to improve crime detection and prevention, providing more accurate intelligence to the police agencies using the technology.
So what, if anything, will slow the growth of wireless video? The main issue, according to IMS Research, is the knowledge and skill set of the systems integrators that install wireless video surveillance. However, as the opportunities continue to increase in city surveillance, more and more integrators will get on-board with wireless technology and it looks set to be a major growth area in the video surveillance industry over the next couple of years.
