4 Main Differences Between Nvrs and Dvrs

More and more people feel the need of extra security at home and at the office. Whether you’re looking for that comfort feeling while at home or interested in protecting your business while nobody is at the office, one thing is clear: you need to learn more about surveillance cameras. The industry has experienced a boost in the last few years, which explains the big number of options available. Most people will discuss around megapixel/IP cameras but you should not oversee recording and storage either. I know that it already seems a bit confusing, so I’ll begin by telling you more about NVRs and DVRs, the two main types of surveillance cameras now on the market and two of the most popular choices. Here is what you should know.

A DVR or digital video recorder is a surveillance device that basically works like a video encoder. The DVR uses an analog CCTV camera in order to obtain an analog video signal and it then compresses the signal and stores it on a hard disk drive. The NVR or network video recorder is a device that works like a computer program, relayed over a network cable. The NVR can only be linked to IP cameras using either an internet network or a LAN.

Now that you have a more clear idea about what the NVRs and the DVRs are, we think that it is important to get a better understanding about the differences between them. Both surveillance camera types represent a good choice in the right environment, so it is important for you to understand when and where each of these represents a wise investment. Here are 4 of the main differences between NVRs and DVRs. Keep in mind that it is with the help of this nvr dvr comparison that you will wisely invest your money in a system that fits the needs of your house or business.

  1. When you select a Network Video Recorder, the video input comes, just as the name itself says it, from the network. This means that the video has already been encoded at the cameras in use. For those who don’t know, encoding means converting a digital video file from one format to a new format.
  2. When you select a Network Video Recorder, you can place it anywhere on the network. The benefit is that you get good protection against network failure, as the NVR can be placed anywhere to provide duplication.
  3. Access is another feature that makes the difference between NVRs and DVRs. To view a video recorded with a DVR, you need to actually be at the DVR while with the NVR, you can view the video remotely.
  4. Last but not least, keep in mind that NVRs are more restrictive than DVRs when it comes to compatibility with security cameras, so make sure that you read all the compatibility instructions before you make the purchase.

Now that you have all these details, we think that it will be much easier to make a choice that you won’t regret.
