2010年5月的時(shí)候高清已經(jīng)做好了準(zhǔn)備，但是網(wǎng)絡(luò)視頻監(jiān)控市場(chǎng)向更高分辨率發(fā)展的步伐有多快呢?2010年大家肯定看到了高清和百萬(wàn)像素網(wǎng)絡(luò)攝像機(jī)出貨量已經(jīng)大幅增長(zhǎng)，然而，標(biāo)清網(wǎng)絡(luò)攝像機(jī)的出貨量仍然比它們的更高分辨率的同行來(lái)的高，約為4：1。
在IMS Research的《世界CCTV及視頻監(jiān)控設(shè)備市場(chǎng)-2010年版》報(bào)告中，預(yù)測(cè)在2011年HD和百萬(wàn)像素?cái)z像機(jī)的出貨量可占到網(wǎng)絡(luò)攝像機(jī)出貨總量的30%。展望未來(lái)，IMS Research預(yù)測(cè)高分辨率安防攝像機(jī)當(dāng)中，HD攝像機(jī)所占比重要高于百萬(wàn)像素?cái)z像機(jī)。
高分辨率攝像機(jī)的需求不斷增加，HD解決方案讓人嘗到甜頭。HD可以提供更高的分辨率，但并沒(méi)有達(dá)到讓存儲(chǔ)和帶寬的成本變得難以控制的程度。此外，在消費(fèi)電子領(lǐng)域中對(duì)高清的偏好已經(jīng)帶動(dòng)了視頻監(jiān)控市場(chǎng)對(duì)高清的需求。
高清網(wǎng)絡(luò)安防攝像機(jī)的銷(xiāo)售量大大超過(guò)標(biāo)清網(wǎng)絡(luò)攝像機(jī)的臨界點(diǎn)在什么地方呢?IMS Research預(yù)測(cè)，到2015年，超過(guò)網(wǎng)絡(luò)安防攝像機(jī)的出貨量的60%將是由高清和百萬(wàn)像素貢獻(xiàn)的。

Looking Into the High Definition Crystal Ball
2010 may have been HD ready, but how fast did the network video surveillance market move towards higher resolution cameras? 2010 certainly saw significant growth in the number of HD and megapixel network security cameras shipped; however, standard definition network camera shipments still outsold their higher resolution counterparts at a factor of four to one.
In IMS Research's “World Market for CCTV and Video Surveillance Equipment – 2010 Edition” report, HD and megapixel cameras are forecast to represent nearly 30% of network security camera shipments in 2011. Going forward, IMS Research forecasts an increasing proportion of high resolution security cameras will be HD rather than megapixel types.
The requirement for high-resolution cameras is increasing and HD has emerged as the resolution sweet sort. HD offers increased resolution but not to the extreme level where the cost of storage and bandwidth becomes unmanageable. Furthermore, the preference for HD in the consumer electronics space has driven the demand for HD in the video surveillance market.
At what point will the tipping point occur when a larger number of HD network security cameras are sold than standard definition network cameras? IMS Research forecasts that by 2015, over 60% of network security cameras shipped will be HD and megapixel resolution.
