Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
The maximum synchronous transmission rate of the original SCSI standard was 5MB / S (scsi-1, also known as narrowscsi, in 1986, the maximum support for seven devices, the clock frequency was 5MHz), and the later SCSI II specified two options for increasing the speed. One is to increase the frequency of data transmission, namely fast SCSI (in 1994, the maximum support for 7 devices) is 10 Mb / S (10 MHz) because the frequency is doubled; the other is to double the transmission frequency and increase the width of the data path from 8 bits to 16 bits. The maximum synchronous transmission speed of widescsi is 20MB / S (the clock frequency is 10MHz, in 1996, the maximum support for 15 devices).

1. IP network remote control users can remotely control it via standard IP networks. It can be used as a primary or secondary camera for a wide range of visual imaging applications ranging from video conferencing to remote monitoring and higher education.
2, 3G-SDI interface Compared with HDMI, using 3G-SDI interface output supports long cables, making the camera particularly suitable for integration in large rooms.
3, 1/2.8 ExmorTM CMOS Imager 60fps High Frame Rate This camera is equipped with a mature 1/2.8 Exmor CMOS imager, which can record extremely low noise even in poor lighting conditions. High-definition video and high horizontal resolution. The 60fps high frame rate operation ensures the natural and clear picture quality of the moving target being shot.
Excellent low light sensitivity (as low as 0.4 lx in high sensitivity mode)
Makes this camera an ideal choice for applications in dark environments.
5, Sony's unique View-DR technology to expand the dynamic range, to ensure that in harsh backlight conditions and low light or dark and other extreme scenes shoot clear images. XDNR technology reduces image noise and ensures that still or moving objects are clearly reproduced in poorly lit rooms, even with digital zoom.
6, 16 preset camera positions, 12X optical zoom The camera's wide-angle lens makes it easier to cover everyone in the room during a video conference. Smooth, quiet pitch, pan, and zoom operations with 16 preset camera positions make it easy and fast to reproduce sharp images without any disruption to the speaker or other audience. The combination of a 12x optical zoom and a 12x digital zoom further enhances the zoom factor, allowing the camera to shoot high quality close-ups from a distance, such as shooting a speaker close-up on the other side of the auditorium.
7. Control by VISCA Command Protocol To improve flexibility, the user can also control the camera by using the VISCA command protocol of the standard IP network.

The third generation of SCSI appeared around 1995, but there was no unified standard
1. Ultra SCSI with maximum synchronous transmission speed of 20MB / S (also known as FAST-20 SCSI, clock frequency of 20MHz);
2. Ultra wide SCSI with maximum synchronous transmission speed of 40MB / S (same as 1);
3. Ultra2 SCSI with maximum synchronous transmission speed of 40MB / S (also known as fast-40 SCSI, clock frequency of 40MHz, 1997).
Later, some newer SCSI standards appeared
1. Ultra2 widescsi with maxmum synchronous transmission speed of 80mb / S (clock frequency of 40MHz);
2. Ultra 3 SCSI with maximum synchronous transmission speed of 160MB / S (also known as ultra-160 or fast-80 wide SCSI, clock frequency of 40MHz plus double data rate, 1999);
3. Ultra 320 SCSI with maximum synchronous transmission speed of 320mb / S (also known as ultra 4 SCSI, clock frequency of 80MHz plus double data rate, 2002); 4. Ultra 640 SCSI with maximum synchronous transmission speed of 640MB / S (clock frequency of 160MHz plus double data rate, 2003, is the latest SCSI standard)
This interface is a convenient interface standard for system integration, cost reduction and efficiency improvement. More and more devices will use the SCSI interface standard. Therefore, there are many hard disks and SCSI CD-ROM drives with SCSI interface. However, due to the cost problem, they are mainly used on medium and high-end servers and workstations.
Sony's latest SRG-HD1 conference camera seven highlights the most beautiful
The SRG-HD1 as Sony's latest product has attracted attention since its launch. Compared to products that are also 3G-SDI video outputs, the SRG-HD1 has almost all the advantages of a Sony videoconferencing camera, such as: 12x optical zoom, 71 degree horizontal wide angle , 2.1 million effective pixels 180/60p resolution. Sony SRG-HD1 application areas: recording and broadcasting classrooms, higher education ladder classrooms, training rooms, etc. 7 highlights:
