In recent years, h.264 has been superceded by new, more efficient compression methods which include H.264+, H.265 and H.265+.Įach new generation of compression means that the same amount of data can be saved in half the space.Īnd the reason that compression technologies have evolved is because of the rise in resolution and frame rate. This is beneficial to businesses who store massive digital video files as part of their operations. In addition, it reduces the bandwidth requirement when sending video file over the network, so it does not eat up the available bandwidth.īecause of the reduction in the size of video files, you can save 50 percent on storage space. H.264 is more efficient as it can provide low transmission bandwidth for videos streamed online in real time. In H.264 format, there is a significant improvement in perceptual quality and at the same time, it can provide a DVD-quality video at less than 1Mbps. This means that it can stream high-quality videos over the web in half the size of the existing formats commonly used like MPEG2, MPEG-4, DivX, etc. H.264, also known as Advanced Video Coding (AVC), is the current video encoding standard that can achieve high-quality videos with greater compression. Many of DVR and NVR kits in my comparison use H.264 What does H.264 mean? Now the capacity of your HDD is an important factor when considering storage but another issue is how the video is “compressed.”Ĭompression is a way of making any video footage smaller and therefore easier to store.Ī gold standard in compression is the H.264 system.

You will just need to buy and install the HDD yourself. Most of the systems in my comparison come with a 2 TB HDD pre installed.īut if you want more storage, all the video recorders are compatible with HDDs with more capacity, many up to 6 TBs. Hard Disc Drives (HDD)Īnother way that DVRs, NVRs and desktop computers are the same is that they all contain amongst many other components a hard disc drive (to store data.)Īnd because video takes up lots of storage space, any system will come with a bare minimum of a one terabyte (TB) HDD. In that way NVRs and DVRs are very similar to desktop computers. There is a VGA and/ or HDMI socket in order to connect an external monitor.Ī USB socket to connect a mouse (and a USB back up.)Ī network socket to connect it to a router.Īudio sockets to connect external speakers and a socket for a power supply. Now, lets take a look at the back of an NVR.Īn NVR doesn’t have those sockets because the cameras connect to it wirelessly.īut most of the other sockets at the back of a DVR and NVR are the same. This DVR can have up to 8 cameras plugged into it. The red box shows the location of the sockets where the cables from the cameras plug into the back of it. The only way to tell an NVR from a DVR is to look at the sockets at the back.

In this they are similar to a TV set top box which also come in all shapes and sizes.
Some are larger than others, some are white and others are black. It would be very difficult to distinguish a DVR from an NVR just by looking at their size and shape. Wireless DVR systems don’t exist but wireless security cameras with NVR are two a penny and since the two systems are almost identical, the switch will be a painless one. What is the difference between an NVR and a DVR?Īnd the one key difference is that DVRs are connected to individual cameras via a CCTV or BNC cable, whereas NVRs are connected to individual cameras wirelessly. What are DVRs and NVRs?įor all intents and purposes they are almost identical with one key difference.ĭVRs and NVRs are used for storing and managing video footage collected from security cameras. However, if you are looking for wireless security camera with DVR, you are out of luck. It will allow you to save hundreds of hours of high quality footage from multiple cameras and to view it remotely all for a one off cost.ĭoesn’t that sound a lot better than the relentless drain of monthly cloud subscriptions? Have you considered a Digital Video Recorder (DVR)? Are you on the look out for a new set of cameras for your business that records all the footage to a local device instead of to the cloud?
