Spy Devices Such As Spy Phone Software Will Help You In More Ways
When people have problems like cheating spouse and unruly children, exercising strictness and severity will only harm their relationship rather than doing any good. So what should be done in such a scenario? Well one pertaining solution is to bring into play spy phone software which actively spy on their activities without their knowledge. Novices, who are inexperienced in working with mobile phone spy, more often than not have the predicament whether or not the spy devices work perfectly.

In the current international financial crisis, video surveillance is one of a small number of adverse economic growth of the industry. Market Research institutions ABIResearch predicted in 2009 there will be two types of sustained and rapid growth of electronic products, which include video surveillance, in particular, IP-based video surveillance applications. According to iSuppli Company Expected, and video surveillance applications is closely related to the China Security Industry from 2012 revenue of 15.1 billion U.S. dollars in 2007 increased to 24.7 billion U.S. dollars.

In the current international financial crisis, video surveillance is one of a small number of adverse economic growth of the industry. Market Research institutions ABIResearch predicted in 2009 there will be two types of sustained and rapid growth of electronic products, which include video surveillance, in particular, IP-based video surveillance applications. According to iSuppli Company Expected, and video surveillance applications is closely related to the China Security Industry from 2012 revenue of 15.1 billion U.S. dollars in 2007 increased to 24.7 billion U.S. dollars.

In fact, the global video surveillance market in 2008 Sell Amount to achieve a 30% to 40% growth, driven by digital video surveillance technology continues to mature and the government Safe City Construction and related industries investment-led. Traditional video surveillance equipment focused on the financial, transportation, public facilities, industrial markets, with the Monitoring equipment Threshold lower and lower prices, especially in large-scale wireless IP video applications, the future monitoring system will be gradually extended to businesses and even home users.

Current 3G mobile Communicate Network has been the major countries around the world to deploy a large area, while increasingly popular WiFi hotspots, wireless broadband IP-based video surveillance applications will show the potential blowout. Wireless IP video surveillance network build flexible and convenient, the city can provide safe, emergency command, Environmental protection Monitoring, monitoring of SMEs, home monitoring for different target user's personal solutions.

Now, including 100 000 000 Victoria East, Hefei and other domestic priorities, as the leading provider of video surveillance design of wireless video surveillance products will be as one of key directions for 2009. In addition to the growth of wireless application development trends, as the large-scale surveillance applications, and network, and intelligent video surveillance system will be an inevitable trend in the development of another. Analysis capabilities with a new generation of intelligent monitoring system will greatly expand the video surveillance applications, in addition to traditional security applications, human behavior (off-site inspection, walking test) and Intelligent Transportation will open a large number of emerging applications.

Blackfin wireless application solutions to meet functional and performance requirements higher Traditional video surveillance applications to industrial users mainly use MCU + ASIC program, such video surveillance applications often achieve a low resolution video signal processing, basic control and data transfer, image quality and poor function was simple. With advances in technology and video surveillance applications demand growth, higher body concept video, wireless IP connectivity and intelligence analysis capabilities to make such applications trend is facing an embarrassing performance stretched.

Wireless and wired transmission biggest difference is the instability of wireless network bandwidth, DSP-based programs are implemented by software, can adjust the video bandwidth, the size of stream, frames, etc. Features optimized video compression for wireless channels algorithm, so no matter how the network, can guarantee the smooth video, unlike the program with MCU + ASIC common phenomenon of mosaic and broken frames. Wireless applications, usually due to a more diverse environment, the wireless module itself is large power consumption and heat dissipation, and even some mobile applications are battery-powered, low-power processor with high demands. MCU + ASIC (or MCU + DSP) chip architecture dual processor determines the power consumption for wireless mobile wireless applications in particular, is relatively high.

In addition, as technology advances, IP-based video surveillance gradually to include more high-definition video experience features of the trend of development, and the result is more complex algorithms, as well as the main processing chip set higher requirements. Traditional surveillance camera CIF format based on pixel resolution, compression standard low complexity, and thus the main chip processing performance not ask for much. But with the rapid development of IP video surveillance and related video standards of progress, people expect a higher image resolution and higher fps, such as the D1 (704 × 576), or higher resolution. Meanwhile, with the popularity of wireless IP video surveillance, also need to consider how the transmission process uses less bandwidth, the MPEG4 and H.264 are becoming mainstream. These higher video resolution and compression format has greatly increased processing power core processors demand. The traditional MCU + ASIC's program to achieve a higher resolution video, usually need to increase co-processor.

In addition, face recognition, active tracking of moving objects, flow statistics and other intelligence have started to extensive commercial. Intelligent image analysis required for such specific applications, traditional solutions can not complete the video analysis requires a large number of computing processing to be beyond the increase in the MCU + ASIC co-processor, this complex solution both BOM cost power consumption is difficult to develop both paltry. Video surveillance system network and distributed processing requirements, and installation of large-scale works on cost, size and power constraints and non-standardized intelligent video analysis, software design enables a flexible and powerful DSP processing capability with more significant advantages.

However, although simple DSP processor has a very flexible approach, graphics processing is relatively strong, but these devices are commonly used in signal processing of traditional architecture, but not for video surveillance and optimal design, which usually occupy more system resources, for some control functions require a higher and higher bit rate the same competitive situation.
