Q:There are hard disk video recorder also need video server, what is the difference between the two, do a large monitor with which

DVR and video encoder principle is the same, are analog video signals into digital signals, easy to store;

Q:16-channel digital hard disk recorders require several cameras

16-channel digital hard disk video recorder, as long as there is less than and equal to 16 of the camera can be used. More than 16 normal use, but more of the camera does not show it.

Q:Hard disk video recorder forgotten, how do?

First, turn off the host, cut off the host power input, follow these steps: 1, remove the cover screws, open the chassis cover 2, in the front panel next to the microcontroller to find J4 pin (marked with Password Clear or Password Reset characters)

Q:What is an embedded digital network DVR?

There is a network function of the hard disk video recorder, embedded machine is said that the machine is placed in a chip inside, unlike the computer, the system is placed inside the hard disk,

Q:Hard disk video recorder started to load what is going on

You can also upgrade the system under the test If your hard disk video recorder is Shenzhen Shian An you can use U disk upgrade to update the system

Q:Dvr video recorder and nvr video recorder difference

DVR: DigitalVideoRecorder (DVR), that is, digital video recorders, compared to the traditional analog video recorders, using hard disk video, it is often referred to as hard disk recorders, also known as DVR. It is a set of computer systems for image storage processing, with the image / voice for a long time recording, recording, remote monitoring and control functions.

Q:Embedded digital hard disk recorders (DVR) what electronic components

First of all your question so that I can not laugh, you even DVR architecture are not clear, but also their own DVR? DVR is divided into hardware and software two parts, so to speak, just like a computer, installed after the machine also installed operating system. DVR development process roughly under: research market, to determine what the development of the product ------ selected the most appropriate development platform, which is the chip manufacturers which program -------- PCB layout, Software development at the same time -------- hardware and software testing and modification ------- trial production -------- and then modify --------- production.

Q:The traditional difference between digital hard disk recorders

Embedded DVR system based on the integration of the hardware structure, the entire video and audio compression, display, network and other functions can be achieved through a single board, greatly improving the overall system hardware reliability and stability. The main functions of the DVR include: monitoring function, video function, playback function, alarm function, control function, network function, password authorization function and work schedule function.

Q:Video probe, optical, digital hard disk recorders 3 how to connect? More than a Guangduan Ji do not know how to connect! Solution, thank you!

2, multi-site multiple camera connection method, each station's camera with video cable connected to the local video Guangduan Ji, and then converged through the optical transceiver to the control center, all the video signal connected to the video matrix, and then connected to the hard disk video recorder.

Q:DVR digital hard disk recorders and NVR network video recorders

DVR video effects depend on the camera and DVR's own compression algorithm and chip processing capabilities, and NVR video effects are mainly dependent on the IP camera, because the IP camera is the output of digital compressed video, the video reaches the NVR, no analog conversion , And do not need to be compressed, just storage, when you want to show and play back you need to extract.
