Click here to know more Common Features And Characteristics Of Digital Video Recorder Servers By Nahshon Roberts As you may know, a digital video recorder server is used in DVR surveillance systems of large public places such as hospitals, sports stadiums, shopping malls, office, and office buildings. These security systems are so large that a machine should be powerful enough to handle as much as 64 video channels! Amazing, isn't it? Here are some characteristics of DVR servers. Operating System and Compression Algorithms Most DVR servers are Linux-operated and they use H.264 video compression technology to provide real-time video recording and playback. Most machines can display video resolutions of up to 720 x 480. This means that your surveillance videos are clear and sharp. The number of channels that a digital video recorder server can handle varies on its design and use. Machines used in small stores can accept at least 8 channels, while those that monitor very large places can hold up to 64 channels. However, the graphical interfaces of some machines can only display 8 channels at a time, so you may have to scroll your way down to get to channel number 64. Common DVR Server Features No matter what the brand or make of a digital video recorder server, you should look for these necessary features: live recording and playback speeds of 480 frames per second (fps), digital watermarking, object count, motion detection, multi-channel display, CD and DVD burning, and pre and post alarm recording. The storage capacity of servers vary with its purpose and use. The longer the monitoring time, the larger disk storage you may need. Cameras, Data Back-up, And Internet Connectivity As mentioned before, an excellent digital video recorder server will always use the most advanced video compression algorithms for the clearest surveillance videos. If you are shopping for a DVR server, always ask if the machine has H.264 compression hardware. Also, most machines come with 18x DVD-RW drives so that you can burn those surveillance videos into DVDs. In terms of Internet connectivity, most servers have remote desktop features and TCP/IP protocols for local area networks (LAN) or wireless area networks (WAN). Any pan-tilt-zoom (PTZ) camera today is compatible with any DVR server. Of course, most machines support multi-viewing protocols. Some can also set presets Digital Photography Success How to improve your digital photos from average to professional standard even if you've never used a digital camera before.

Some are even kept in climate-controlled rooms to make sure that the server does not exceed its temperature thresholds. You might be wondering why. Well, if the server crashes because of too much cold or heat, the whole DVR surveillance system will be completely paralyzed, defeating its purpose. The machine may have its own ventilating system, but the professionals will always tell you not to take any chances. You can always find a different machine with features that are not mentioned here. But it comes with a higher price tag than your garden-variety DVR server. It is always good to evaluate and reassess your security needs so that you will be spending your money right.

With all the DVRs out today, it is important to get one that would suit your needs. Here are a few matters to consider. Number of Surveillance Channels You may have to ask yourself this: "How many channels do I need to monitor?" The number of surveillance channels of your home security system will really trim down your choices. If you want webcams over your living room, kitchen, the master bedroom, and the kids' bedroom, you should get a 4 channel digital video recorder. If you want to monitor more than 4 rooms in your home, you have to get a DVR which can support more than 4 channels. To be sure, consult with a professional for the right specs to get your security system running. Make Sure That Your DVR Has Lots Of Disk Space The more channels that you have for your security system, the greater disk space you will need. You will feel really secure if your DVR can at least save a night's worth of video surveillance. You might be thinking of buying a DVR with loads and loads of disk space. Keep in mind that machines with large storage capacities are considerably very expensive. So make sure to get a machine that answers your video storage needs. Optical Drive Support It would be good if your DVR can burn your surveillance videos unto a CD or a DVD to free up some disk space. When you buy your 4 channel digital video recorder, for example, ask the techies at the computer or electronics shop if the machine can support CD and DVD writers. It also would be great if you can add more hard drives to the DVR. Features and Add-Ons Above it all, you have to know if you can easily operate your 4 channel digital video recorder. With a professional's help, you should buy a very user-friendly and intuitive machine with great security features such as motion detection, colored coded video bars, high quality video recording and playback, and remote viewing. If you need a 4 channel digital video recorder, look for a machine that does not need mad computer skills to operate even the most basic of functions. Look At The Price The best machines and electronic devices do not come cheap, especially those that come with great features and 24/7 customer support. If you can afford the expensive machines, go for it. For sure, a pricier 4 channel digital recorder works so much well than affordable ones. Indeed, you have to shell out the dough to get your system running, but the promise of having a very secure home is really worth the price.
