Quad application scope and difference with screen splicing
Quad, also known as monitoring Quad, 4-split, 9-split, 16-split several, 4, 9, 16 months of surveillance camera images can be displayed simultaneously on the monitor can also be sent to the VCR on records. Quad is one of the most commonly used equipment, its cost performance is also better image quality and continuity to meet most of the requirements. 9 divisions and 16 divisions more expensive, and after the split Each image resolution and continuity will decline, videos ineffective. In addition there are six division, eight-divided, double four segmentation device, but the image ratio, clarity, continuity is not ideal, low utilization of the market, most of the splitter can simultaneously display images, the single screen can also be displayed time and the characters, settings can be superimposed automatically switch alarm equipment.
Basic working principle
The image compression and digital processing of the method, several picture compression by the same proportion in the screen of a monitor. Some also comes with built-in sequential switcher functionality, this feature can be input each surveillance camera full screen rotation order and interval output switch the screen on the monitor (like switching host turns that), and available recorders press The above sequence and time interval recorded. Interval is adjustable.
Quad Scope
The number of surveillance camera CCTV surveillance systems in large buildings, up to hundreds, but the number of monitors by the limit of the engine room area is much smaller than the number of surveillance camera. And the number of monitors, too much is not conducive to comprehensive inspections of the duty officer. To panoramic surveillance surveillance camera signals can be displayed on the monitor screen, you need to use more than Quad. This device is capable of multiple video signal synthesis into a single output, enter a monitor screen, so you can display more than one screen at the same time. Split ways often 4 screens, 9 screens and 16 screens. Multi-Quad monitor simultaneous viewing of multiple surveillance camera signal, and it can use a VCR while recording multiple video signals. Some preferred multi Quad also having a single channel playback function, i.e. any way to select the multi-channel signal of the video signal recorded on the monitor screen full discharge.
Screen splicing (splicing controller) distinction
Can support multi-screen splicing is a complete image signal into N blocks assigned to the the N video display unit (such as rear projection unit), complete with multiple video unit composed of a large screen dynamic image display, kinds of video equipment access, such as: DVD surveillance camera satellite receiver set-top box standard computer A signal video wall processor can achieve more multi-screen processor physical output combined into a superposition of a resolution of ultra-high resolution display output, the screen wall constitutes a super-high-resolution, ultra-high brightness, large display size of the logical screen to complete multiple signals source (network signals RGB signals and video signals) zoom in the screen on the wall fenestration mobile and other display function of ways.
Quad to panoramic surveillance surveillance camera signals can be displayed on the monitor screen, you need to use more than Quad. The device is capable of multiple video signal synthesis output all the way to enter a monitor screen, so you can display more than one screen at the same time. Split ways often 4 screens, 9 screens and 16 screens. Multi-Quad monitor simultaneous viewing of multiple surveillance camera signal, and it can use a VCR while recording multiple video signals. Some preferred multi Quad also having a single channel playback function, i.e. any way to select the multi-channel signal of the video signal recorded on the monitor screen full discharge.
