H.265 IP Camera and H.264 IP Camera difference

As increasingly demand in users on the surveillance video quality, high-definition video applications in the security surveillance is becoming increasingly popular, which brought a sharp increase in storage space and costs. Compared with the H.264 encoding technology is now being used, a high compression rate characteristic of H.265 can save about half of the storage space, thereby significantly reducing the cost of storage of the video. Compared with H.264, H.265 best advantage is under the premise of maintaining the image quality, make data transmission bandwidth is reduced to half of H.264. At the same time it supports up to 7680 × 4320 resolution, so even 2160P even higher levels of ultra-high-definition video can be encoded by H.265  format.

Due to limitations H.264 macroblock, resulting in the video processing load is also increased significantly. HD eventually face the problem of the high frequency treatment, bloated feeling. And with respect to the H.264, H.265 macroblock type in the full lifting of a hierarchy, the original module type 16X16 raised to the highest 32X32,64X64, even 128X128 macro blocks. Thereby reducing the number of high-definition digital video macroblock, the macroblock is used to describe the content of reducing the parameter information, and the transform block size corresponding shaping expanded repeat the compression efficiency of the device.

In addition, H.265 is also used to update the motion vector of the test. In addition to the above-mentioned aspects, H.265 achieve a more breakthroughs in multicore parallelism ,in some new technology under the WPP, such that it can be a higher degree of parallelism in order to meet a variety of needs under the premise, can achieve high compression efficiency in the work process.

 

Through technical analysis above, we find that H.265 has a lot of technology to over than H.264. In terms of functionality and performance, H.265 is better than H.264 , H.265 come to world just a time .

In short, H.265 bring new hope  to us for high-definition monitor, many areas can not wait  for it. From this perspective, although the current application status for H.265 popularity is still very far away, but birth of H.265 is also destined ,and for problems it may bring also  waiting for solve, but H.265 in the future dominance is the undisputed facts.

Mobile NVR Instead of mobile DVR

3G Mobile NVR + HD IPC  is becoming popular

3G Mobile NVR  It's mainly driven by the trend of HD  surveillance and popular network , 720P, 1080P or higher resolution monitor products have become the mainstream of surveillance market , and network also replaces the traditional analogue transmission, has become a carrier of high-definition  , although this time analog surveillance play a leading role in traditional vehicle monitoring system, But Car NVR + HD IPC monitoring  is changing the landscape of this market.

Portable NVR is typical used incars, trucks, busses, trains, airplanes, boats, ships and external applications suiting public transport & law enforcement solutions.
WiFi and 3G mobile broadband options also available for instant communications for live video
feeds & real time data.

NVR Manufacture - Cloud Storage NVR

Sysvideo Recently Released Cloud StorageNVR ,It can storage snapshot automatically and video clips manually .

NVR cloud storage solution was a mainstream storage technology

Video surveillance as an important important of proof of time,it’s widely used in  bank,  judiciary, the application and safe cities, and with the development of technology and the needs of the times, there are many places are installing a high-definition camera. The data in these areas need to store time in 1-3 months or six months or more. The arrival of high-definition era, requires not only that the clarity of high-definition camera, but also hhigh-definition picture storage , which is a great challenge for storage technology.

HD monitor storage requirements

According to modern security monitoring storage requirements can be simply summed up as "high five":

High capacity: HD brings storage capacity soared, needs a stable and reliable high-capacity storage: increase the capacity of a single system: extended by cascading multiple SAS JBOD, support 3TB, 4TB hard drives, enhance RAID robustness; using clustered storage systems : Enhanced storage system elastic scalability, reliability compensate for the lack stand-alone

;

High performance: high-definition monitor  has great requirement on storage bandwidth and storage performance to be tuned according to the monitoring features: Performance optimization: stream high-definition big concurrent data streams in different modes (read-write, edge deletion and writing, RAID rebuild) the IO performance optimization, NAS performance optimization; application combining: NVR software is embedded in the application processing power, a reasonable allocation of system resources;

Energy-efficient: Behind the massive storage deployment is a lot of energy consumption, high cost, low power monitoring equipment should be designed: the DVR era, monitor manufacturers to reduce power consumption by hard holiday, extend life, and network storage can use MAID energy savings, but more suitable for a backup archive MAID environment; considering monitoring applications is 7 * 24 uninterrupted, choose high power conversion efficiency (80Plus power supply or DC power supply) is more valuable, can decreased energy consumption on the condition of not affect the application .

High Density: basic security monitoring demand for storage is to reduce the cost per TB, the cost per slot: After the popularity of high-definition monitor, the original 3U16-bay equipment, limited storage capacity of a single, high-bay storage can support more cameras; 4U24 bit more high-density disk storage, each slot can effectively reduce costs, increase the storage capacity of a single, saving rack space;

High Application: Storage must be designed based on actual demand, solving customer pain main concern in order to survive: excessive file fragmentation results in performance degradation, vulnerability of the file system after a power failure, streaming direct writing, efficient indexing structure; improve NVR embedded applications convenience and compatibility, support for Windows / Linux software, provides API interfaces with external monitoring subsystem, to achieve high efficiency analysis, rapid positioning in massive data; in UIT's SV1000G2 example, from product design to run through. "5 high ", using end SAS6Gb technology, Intel latest SandyBridge platform to improve performance, 4U24 / 4U36 high-density design, support 3TB hard drives to increase storage capacity of a single system, reducing the cost per slot; applicable conversion efficiency up 90% of 80Plus power supply, you can save more energy, reduce system operating costs; may be more closely integrated with the monitoring system through architecture optimization.

Factors Affecting the Quality of Surveillance Camera Video Images

Factors affecting the quality of surveillance camera video images

Main role: to enhance color purity degree at day, improve night vision effect, so that images during the day and night look clear and realistic.

Human eye can see a variety of wavelengths of light in nature, but the imaging element of the camera can only see part of the wavelength, so there are differences in the camera screen color and eye to see. No IR-CUT daytime surveillance cameras will become pale green, red objects become very pale color, lack of light at night, often a black screen.

IR = infrared = IR

CUT = filter, minus

IR-CUT dual filter switch is made: filter (an infrared cut filter and an all or absorbed through the spectral filter) + dynamic part (may be electromagnetic, electrical or other power source) form.

IR-CUT double filter in the camera lens group put a set of filters, according to various wavelengths of nature, to block or release the light through, get the best imaging light. When infrared sensors to detect the point outside the lens changes in light intensity, the built-in IR-CUT filter can be followed automatically, switches automatically switch according to the external light intensity. That is, during the day or night, double filter can automatically switch filters, therefore, whether in daylight or darkness, can get the best imaging results.

Infrared filter technology

The main role: to improve the image color cast problems, so the monitor screen color close to the naked eye, more real.

Infrared cameras on the market no filtering technology, the technology is green sub-wood out independent research. Mainly for monitoring color cast problems during the day on the basis of IR-CUT improved on. The imaging element of the camera, like the human eye can not feel like the various wavelengths of nature, so many wavelengths can not be reflected on the screen. Ordinary camera monitor screen becomes gray green screen color fades, screen cast serious. Infrared filter technology is set in the lens you can block certain long infrared bands through cause image distortion. All cameras’ screen without distorting true colors.
