Monitor 256 into 32 video matrix video switching server host to send keyboard software positive ..

Video surveillance matrix what role the matrix effect is the use of the limited monitoring equipment can see more images, while remote control PTZ related to clearly see the need to monitor the situation! ! Random matrix with the keyboard to switch the image to any input on any output terminal, and can control the PTZ up and down, left and right, the lens distance, the length and the camera switches. Now in the security industry has emerged DVR, I personally think it is partially replaced the function matrix, and can replace the original old-fashioned VCR, as well as Quad. But do not think that can replace hard disk video recorders matrix switcher, which is due to limited resources 1. After the computer; 2. DVR uses a computer-controlled, and its development will be restricted computer development; 3. Any one development of things to the last will of a single work, so as to make the system stable. Now we just too focused on the development of DVR, it ignored the existence of the matrix switcher, but also due to the matrix switch has not converted to digital, so it makes more and more people believe that as long as there is on the line DVR , but we should not forget that 64 DVR can only be done in, and the matrix into 4096 now can be done, this advantage is a short time for the DVR can not! 256 into 32 monitoring matrix switching matrix switcher host Product description: Matrix main features: ● Each video outputs with OSD display ● use (optional) Built-in IP control module and video server design, through IP network ● host matrix operations and switching view the video, and the camera and remote control of the system access ● 2U card using high-density module structure, easy expansion ● You can set the keyboard combination of monitor, camera authority; the system can be partitioned Set ● hot backup host matching design, more secure stability of the host ● audio / video input and output ports and communication interfaces have surge protection measures and anti-lightning interference design ● system can be more than one multi-level matrix network via RS485 ● An external 16 sub-control keyboard and supports a variety of networking features three or more ● comes with full English menu, various functions can be carried out after a pre-set matrix ● alarm can be linked to automatically turn on the camera and lights, automatic switch preset point and start recording ● image can be preset to any zone alert mode: time, manual, often arm / disarm and alarm records query ● Built-in 16 channel alarm input, 2 Lujing output, alarm interface units can be cascaded alarm expansion. ● switch matrix system can be divided into free, program switching, synchronous switching, switching and alarm changed into 5 groups system switching mode.
