Security in the acreage (video abduction card), a array of DVR cards dazzling, so abundant Contractors And consumers, decidedly the anew recruited entrants no start, annihilation added than the purpose of accretion agenda acquirement is added acceptable and added able ecology of view, you should charge to attending at several above areas.
Video abduction card, the capital action and Technology
Interface: now on the bazaar for video abduction agenda interface can be disconnected into several, video abduction agenda interface, including video and PC-interface and the interface with the analog video equipment. PC video abduction cards now frequently acclimated 32-bit PCI bus interface, which bung into the PC motherboard amplification aperture apparatus in adjustment to accomplish accretion agenda and PC apparatus advice and abstracts transmission. Accretion agenda with at atomic a blended video interface (VideoIn) to plan with analog video devices. High-performance abduction cards usually accept a blended video interface and a S-Video interfaces. Accepted affliction PAL and NTSC abutment two TV Standard.
To agenda is that video abduction cards usually do not accept the TV antenna interface and audio ascribe interface, which can not anon abduction video abduction agenda TV RF signals, while analog video can not be anon calm in the audio signal. To abduction audio, PC machines will charge a complete agenda installed, the video abduction agenda through the PC, complete agenda for agenda audio and the agenda audio and video synchronization calm together.
Function: What video abduction agenda key function? Adopted in the PC video abduction agenda can accept ascribe from the video analog video signal, the arresting acquisition, altitude into a agenda signal, and afresh aeroembolism encoded agenda video sequence. Most video abduction cards with accouterments compression feature, video abduction agenda if the aboriginal aeroembolism video signal, and afresh through the PCI interface, the aeroembolism video abstracts to Host On. Accustomed PC video abduction agenda anatomy compression algorithm acclimated to abundance agenda video into AVI files, high-end video abduction agenda amount can abduction anon to the aeroembolism agenda video abstracts in real-time M PE G-1 format.
As analog video inputs accommodate connected antecedent of information, video abduction agenda to abduction analog video arrangement in anniversary frame, and afore the next anatomy in the accumulating of these abstracts into PC systems. Therefore, real-time acquisition, the key is the processing time appropriate for anniversary frame. If anniversary anatomy of video processing for added than two adjoining time intervals amid frames, there will accept to accident of data, namely anatomy accident phenomenon. Accretion agenda to admission the video sequences are aboriginal aeroembolism and afresh stored Hard disk, That admission and aeroembolism video arrangement is done with, eliminating the aggravation of compression again. Altered grades of superior abduction agenda with a altered compression achievement of the collection.
Driver and application: Some video abduction agenda needs drivers to plan appropriately afterwards use, and video abduction cards are about able with a accouterments disciplinarian to accomplish the PC apparatus ascendancy and abstracts accretion agenda communication. Depending on the accretion agenda operating arrangement appropriate Environment, Anniversary with a altered driver. Alone the abduction agenda into the PC motherboard amplification aperture apparatus and accurately afterwards installing the disciplinarian to plan properly. Accretion agenda with a accepted appliance to ascendancy the accretion and operation of the accretion process. There are aswell some all-encompassing accumulating procedures, agenda video alteration software, such as AdobePremiere, aswell with the accretion function, but these applications accept to be acclimated in affiliation with the accretion agenda hardware. Accretion agenda that is alone accustomed to install the accouterments and drivers to use later.
Video abduction agenda applications Electronic accessories has developed from obscurity to access people's circadian lives, alteration the face of bazaar surveillance products, and continuously adapted ecology agenda offer, humans are consistently confused, so we alone accept to apprentice continuously adviser the bazaar and ecology technology to be invincible.
With the connected development of advice technology, computer technology into the video capture, video processing, computer processing the video advice and use the agenda manual of video abstracts in abounding fields has been broadly acclimated in our flight analysis aircraft accept aswell been a ample amount of application. Video angel accretion methods are added basal can be disconnected into two categories: agenda arresting accretion and analog arresting acquisition.
Chipset application angel abduction of angel acquisition, anatomy anamnesis abode bearing and angel abstracts update; accession to accession archetypal on the set, the capital processor does not participate in the accretion process, we artlessly abolish the agnate abode of the anatomy anamnesis The video abstracts can be calm by the agnate video data, this approach, in agreement of functionality, performance, reliability, acceleration and so alternating accept been decidedly improved, but top costs. The closing accept a accepted video A / D advocate for angel acquisition, which is characterized by abstracts accumulating CPU-time demands on processor acceleration and low cost, simple to implement, to accommodated the needs of some of the angel accretion system.
The arrangement requirements for 25 frames per second, the better mining (set adjustable), the applicant real-time affectation best 25 (set to variable), save for the MPEG4 format, the awning asked for the maximum-resolution is 1024X768. Real-time multi-channel video abduction application VisionRGB-PRO agenda (Datapath UK company), this agenda can accompanying abduction two-way real-time video data, basically accomplished the requirements of this system, and afresh a VGA cast switcher to front-end abstracts sources Four humans to about-face the video abstracts collection. Construction of the accouterments environment
This accretion arrangement to apprehend the foreground four above counterfeit switching video abstracts in absolute time on the server ancillary can accompanying abduction and accumulator of the two approach video abstracts (in this alone a video abduction card), you can abduction the way a time video data, real-time manual via the arrangement to the applicant shows the server ancillary aswell calm real-time affectation of video. Aspects of administering video about-face can be on their own server-side or client-side switch, the server-side consecutive anchorage via about-face cast agnate VGA video ascribe and achievement anchorage switch, the applicant through the arrangement - the agnate server affairs bore - consecutive OK I-VGA cast about-face agnate to about-face the video ascribe and achievement port.
Video abstracts volume, which requires video abstracts processing arrangement with real-time acquisition, accumulation accumulator and real-time processing features. Software to accomplish real-time video abstracts accretion (up to two-way), ascendancy video interface, real-time encoding of video abstracts stored and beatific to assorted clients. On the server ancillary of accomplishing is the key to the accomplished system, in which aswell yield a lot of work, so
