Q:There are hard disk video recorder also need video server, what is the difference between the two, do a large monitor with which: Design large-scale monitoring, then look at the budget and network layout: relatively speaking, hard disk video recorder front-end storage model, the cost will be lower, the network pressure will be relatively small; video server as a result of centralized storage, the network requirements will be higher The On the current video surveillance network, digital trends, the video server or network camera is the first choice, improve image clarity, more convenient for future expansion.

Q:Matrix, computer, hard disk video recorder, how to connect the TV wall: And can then be monitored via a network connection to local monitoring or remote monitoring to a DVR and a digital IP matrix.

Q:Monitor the hard disk video recorder how to pick up the computer: VCR behind the network cable jack is connected to the Internet, the video recorder network after an ip address (such as 192.168.0.2) computer also have networking, the computer network to open a web page, the address bar into the video camera ip192.168.0. 2, will be able to visit

Q:Hard disk video recorder dedicated hard drive and ordinary computer with the hard disk What is the difference: In general, the performance of the dedicated hard disk is about the same as the server hard disk, because the server and the work characteristics are very close. But the monitoring industry's data throughput as the server, so the speed is only flat and ordinary hard drive. Life than ordinary hard drive durable, of course, any product may be a failure, monitoring dedicated hard drive is not every one will use ten years eight years without failure.

Q:Hard disk video recorder forgotten, how do?: 6, re-turn off the host, cut off the host power input 7, unplug the short circuit block, re-J4 pin 1, 2 legs (near the resistance R5) placed in the open state 8, fixed on the chassis cover, password cleared.

Q:16-channel digital hard disk video recorder 1TB hard drive can save how long video?: The other with the default settings on it.

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:Dvr video recorder and nvr video recorder difference: In simple terms, through Nvr, you can watch, browse, play back, manage, store multiple webcams at the same time. Out of the computer hardware to tie him down, no longer have to face the tedious. If all the cameras are networked, then the only way is to have a centralized management core.

Q:Digital DVR parameters: Video output: one composite video output (BNC interface, 1VP-P, 75Ω) PAL system (625 lines) NTSC system (525 lines)

Q:What is the amount of data per channel for a digital video recorder? What is the hard disk space occupied by CIF and D1 machines per hour per hour? Column formula: Here in addition to 1024 is the M conversion into G if 8 channels * 200M / hour * 24 hours * 30 days / 1024M = 1125G. Using D1 resolution, usually the value is 500MB / hour D1 formula is the same
