Same as three-dimensional T304 four-way real-time USBVideo capture card, With high picture quality and high audio effects, and the efficiency is currently common on the marketUSB capture card4 times. With four-channel video signal input, four-channel audio signal input, with complete and three-dimensional video monitoring software, using USB2.0 interface. It can be easily used in both desktop computers and notebooks. It is a USB capture card with excellent performance, easy to use, and multi-channel simultaneous capture.
T304 four-channel USB video capture card has four Video video inputs, and can be captured at the same time. It is widely used in video capture and video surveillance, and can be connected to various video source equipment such as DV machines, DVDs, VCDs, digital set-top boxes, digital cameras, etc. .
Same as the three-dimensional T304 external USB interface capture card for its easy installation, eliminating the cumbersome opening and dismantling of the main computer box, and the advantages of carrying, it is favored by customers. However, the current USB capture card adopts the USB2.0 high-speed interface and has a total bandwidth of 480M, which cannot realize multi-channel video real-time transmission. Therefore, all USB capture cards currently on the market are 1 channel real-time 4 channel non-real-time products.
With the latest technology, Tongsanwei Electronics breaks through the bottleneck of computer USB bandwidth and realizes USB real-time collection of 4 or even 8 channels of video. The T304 four-channel USB video capture card has four channels of video capture and four channels of audio capture. It is directly connected to the main board through the USB interface, and it does not need to be connected to a sound card to realize the simultaneous capture of video and audio. The installation is simple and does not require an external power supply. Below we introduce the main parameters of this four-channel USB video capture card:

Graphics card requirements | There is no requirement for the graphics card, support for independent display, integrated display, and no video memory requirements (It is recommended not to use counterfeit graphics cards, because counterfeit graphics cards are modified from old graphics chips, and the driver is actually wrong) |
【Description】: USB bandwidth. At present, our technology can break through the transmission of 4 channels of D1. That is to say, if you only do 4 channels of real-time video capture, you can achieve the effect of D1 (4CIF) on each channel. If you need to achieve 8 channels in real time, each channel Only HD1 (2CIF) real-time can be achieved. If 16 channels of real-time are needed, each channel can only be CIF real-time.
Product question answer:
1. Is there no four-way USB capture card currently on the market? What is the difference between your products?
Answer: The USB capture cards currently on the market use a single-channel chip solution. When doing one channel, it can achieve a D1 (4CIF)/25 frame effect, or two channels of 12.5 frames/4 channels of 6 frames CIF effects, audio There is only one input. The same three-dimensional uses industrial-grade chips with powerful performance and high stability. It does not need an external power supply to realize 4-channel D1 (4CIF) video 25-frame real-time acquisition. The efficiency is 4 times that of ordinary USB capture cards on the market. At the same time, we also launched a product that can capture 8 channels of video in real time, and through the two combinations, meet the various needs of 8, 12, and 16 channels.
2. Do you need to install a driver for your USB capture card? What is the function of the capture software?
Answer: Our products use professional chips for image processing and need to install drivers before they can be used. The acquisition software adopts our mature and stable same three-dimensional acquisition software, which is powerful and stable. It supports remote network monitoring without the need to register a second-level domain name. You need to log in to the domain name, enter the user name and password to remotely monitor.
3. Does it support WIN7 system?
The current driver supports Windows 2000/Windows XP/Windows 2003/Vista/Win7
4. USB and DVR capture card comparison:
The USB video capture card is small in size, popular in design, compact and beautiful in appearance, and easy to carry.
It can be plug and play, support hot swap, install and use without disassembling the case, with advanced USB2.0 high-speed interface, can capture high-quality dynamic and static images, support laptops with built-in USB 2.0 interface, can easily convert The video content in the DV camera, video recorder, and player is collected into the computer for production and cutting.
The USB capture card is an external video capture card that does not require disassembly and assembly of the board. It is powerful and easy to install. It does not require an external power supply and is powered by the USB interface. It has good compatibility and can be used on desktops and laptops. You can watch the video output from video, VCD, DVD, camcorder and other equipment on your desktop or laptop.
Due to the USB2.0 interface, it has support for D1 acquisition and good compatibility. It is suitable for the monitoring of small systems, or using a notebook for monitoring, which is very convenient and practical. Using the popular H264 compression technology, the image is clear, the unique electronic zoom function of the monitoring software, and the disk pre-distribution system make it convenient for users to use.
This four-channel USB video capture card has undergone 7× 24 hours endurance testing, and is widely used in video surveillance, video capture and other fields. It has realized a four-channel image display and a video capture card with audio input. Consultation hotline: 010-51295660.
