Consider These Features Before Purchasing A CCTV Digital Video Recorder

Are you struggling to narrow down on one particular CCTV digital video recorder (DVR)? Since there are different specifications to consider, it can get rather difficult to decide which DVR is good for your CCTV system. You may be sure about the cameras that are going to be used in the system but selecting a DVR can pose problems. In this blog, we’re going to tell you some of the key things to consider when shopping for a DVR. We have listed down some points for this purpose. Let’s take a look at them.

  • The first thing you should look for in a DVR is the number of video channels it can handle. By channels, we are referring to cameras that a DVR can record simultaneously. Most DVRs in the market offer 4, 8, or 16 channels. Most buyers go for DVRs that can record 8 channels at the same time. Keep in mind that audio channels are separate and there are certain recorders that only record audio from one of the channels
  • The next thing is the resolution. You can expect to get max resolution of 720x576 pixels from most DVRs sold online. But there are some recorders in the market, for instance 8CH Titanium TVI/AHD/CVI/IP Hybrid DVR manufactured by ENS Security, that can work with both analog and IP security cameras at the same time and record in 1280x720. But before you focus on getting the best resolution, make sure you know about the following points
  • You should also look at the frame rate of the recorder. DVRs with a frame rate of 25fps can deliver flawless recording with virtually no jerkiness. However, if you need to get the best quality, then you need to get a DVR that can record 25fps per camera at max resolution. Do look for this specification properly as some recorders available online say that they have a good frame rate but they record only at half resolution. So, do check whether the frame rate of the recorder will work fine in max resolution
  • There is a built-in HDD in DVRs. So, when shopping for a DVR, consider the size of the hard drive as well. This is dependent on the frame rate of the recorder, resolution, number of channels, etc. Ideally, it is best to go with a DVR of 500GB drive. If you’re using more channels, high frame rate, and resolution, then there are DVRs that offer 1TB or even 2TB drive as well

Apart from these, you can check whether a DVR offers online access or not, which means can it allow you to see the footage from the channels via the Internet or on a mobile device. Also look for motion detection and scheduled recording modes. At Affordable Home Electronics, you can buy DVRs that can offer 8 CH TVI/ AHD video input; CVI video input; multiple mode recording such as manual, time, and motion; remote control via IE or CMS; H.265 high profile compression format, etc.
