當(dāng)前,許多領(lǐng)域都正在發(fā)展無(wú)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(jì)環(huán)境中無(wú)疑是非常流行的。第二,無(wú)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(wú)需再挖開(kāi)路面。第三,無(wú)線技術(shù)能夠用于臨時(shí)的視頻監(jiān)控工程,這種靈活度是有線監(jiān)控方案無(wú)法提供的。在當(dāng)前經(jīng)濟(jì)緊縮的情況下,隨時(shí)移動(dòng)攝像機(jī)到你需要用到它們的地方,是比買(mǎi)一個(gè)新的攝像機(jī)更有吸引力的選擇。 最后,最適合使用無(wú)線基礎(chǔ)設(shè)施的終端用戶(hù)產(chǎn)業(yè)是城市監(jiān)控,它恰恰是視頻監(jiān)控成長(zhǎng)最快的垂直行業(yè)。事實(shí)上,最近城市監(jiān)控市場(chǎng)的增長(zhǎng)潛力被海康威視的公告點(diǎn)亮,??低暿且粋€(gè)以中國(guó)為市場(chǎng)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(guó)重慶一個(gè)價(jià)值8億美元的平安城市項(xiàng)目的總承包商。
在其他地區(qū),如中東,無(wú)線基礎(chǔ)設(shè)施也被用來(lái)把監(jiān)控視頻實(shí)時(shí)地從警車(chē)傳送到指揮中心。這種把移動(dòng)和固定位置相結(jié)合的方式十分有潛力,它可以提高對(duì)犯罪偵測(cè)和預(yù)防,使用該技術(shù)可以為警察機(jī)關(guān)提供更準(zhǔn)確的情報(bào)。
那么,還有什么能減緩無(wú)線視頻監(jiān)控的成長(zhǎng)呢?根據(jù)IMSResearch的研究,主要存在的問(wèn)題,是系統(tǒng)集成商安裝無(wú)線視頻監(jiān)控所要具備的無(wú)線知識(shí)和技能。然而,由于城市監(jiān)控中的機(jī)遇不斷增加,越來(lái)越多的集成商將掌握無(wú)線技術(shù),而且看起來(lái)在未來(lái)幾年,無(wú)線監(jiān)控將會(huì)是視頻監(jiān)控行業(yè)的主要增長(zhǎng)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.
