As you may know, a server digital video recorder is used in DVR surveillance systems of large public places such as hospitals, stadiums, shopping malls, offices, office buildings. These security systems are so great that the machine must be powerful enough to handle up 64 channels of video! Amazing, is not it? Some features of DVR servers.
On the operating system algorithms and compression
Most servers are Linux-based DVR and they use the H.264 video compression technology to provide registration real-time video and reading. More machines can display video resolutions up to 720 x 480. This means that your surveillance tapes are clear net and. The number of channels of digital video recorder server can handle varies in its design and use. The machines used in small shops can accept at least eight channels, while those who oversee high places can accommodate up to 64 channels. However, the graphical interfaces of certain machines can only display 8 channels at once, so you might have to scroll your way down to get the channel number 64.
Characteristic Commons DVR Server
No matter what brand or make of a server digital video recorder, you should look for these features needed: a live recording and playback speed of 480 frames per second (fps), digital watermarking, a number of objects, motion detection, simultaneous multi-channel, CD and DVD burning, and pre and post alarm recording. The storage capacity of servers vary depending on its purpose and its use. The more time monitoring, storage disk bigger than you might need.
Cameras, data storage and internet connectivity
As mentioned previously, an excellent digital video recorder server always use the most advanced algorithms for video compression for video surveillance clearest. If you are shopping for a DVR server, always ask if the machine has hardware H.264 compression. In addition, most machines are equipped with DVD-RW 18x so you can burn these surveillance tapes to DVD. In terms of Internet connectivity, most servers have features and remote desktop protocols TCP / IP local area networks (LAN) or wireless networks (WANs). Any pan-tilt-zoom (PTZ) camera is now compatible with any DVR server. Of course, most machines support multi-display protocols. Some can also set presets and operation templates for your security cameras.
Ventilation
Indeed, a digital video recorder server is a machine very sensitive. Some are even kept in temperature controlled rooms to ensure that the server does not exceed the threshold temperature. You might ask why. Well, if the server crashes due to too much cold or heat, all DVR surveillance system will be completely paralyzed, defeating its purpose. The machine can have its own ventilation system, but professionals will always tell you not to take risks.
You can always find a different machine with features that are not mentioned here. But it comes with a price tag higher than your garden-variety DVR server. It is always good to assess and reassess your security needs so that you spend your money right.
