What is a DVR system? 5 Best

Over the years, the need for video surveillance has increased both at commercial and residential levels. Video surveillance plays a vital role in different critical situations; it helps deter and prevent crime and keep a close watch on an area.

Gone are the days when video surveillance are only found in commercial areas. These days, most homes install cameras to watch what is happening within and outside the home closely.

So if you are shopping for a video surveillance system, you will most likely come across two types of systems – NVR and DVR. Although both systems perform the same function to record video footage, they record the footage differently. This article will be centered on the DVR system, what it means, features, pros, and cons.

What is DVR?

Digital Vidoe Recorder (DVR) is an analog streaming device designed to record video digitally. It works with analog cameras to stream raw video footage to recorders using coaxial cables. The recorder processes the video footage once a connection is established.

To view the footage on a DVR, you can connect your smartphone, computer, laptop, tablet, etc., to the DVR. A DVR is quite affordable, unlike the NVR system. And they are suitable for small and domestic applications which do not involve long-distance data transfer or remote viewing.

Most DVR systems in the market come with tons of outstanding features. Some DVR systems are capable of recording footage from up to 16 CCTV security cameras simultaneously. Also, while some DVR system comes with hard drives that enable users to store and back up recorded footage, others do not.

In addition, some advanced DVR systems support cloud storage and mobile app integration, so you do not miss any moment. With the mobile app and cloud storage, you can access footage in real-time remotely.

Components of a DVR System

A DVR system has three components, which are:

  • Analog Camera

A DVR system uses an analog camera which is responsible for streaming an analog single to the recorder. Once the streaming is done, it processes the video data for viewing, downloading, and transferring.

  • Coaxial Cables

With a coaxial cable, you can connect the analog camera to the DVR system. Although this cable does not support power supplying devices on the same line, it allows data transfer.

If you use a coaxial cable with your DVR system, you might need another cable to transmit electrical signals. This is to enable audio transmission as most coaxial cable does not support audio transmission.

  • AD Encoder

DVR systems rely on AD encoders to process the raw data streaming from the camera into viewable footage. So, every camera must be connected to both the recorder and a different power source for this security system to function correctly.

Pros of DVR Systems

  • Affordable
  • Easy to set up and use
  • Great for observing
  • Signal stability
  • Great image quality
  • Minimal bandwidth usage

Cons of DVR Systems

  • Requires extra cables and wires
  • Lower frame rates
  • Requires separate power source
  • Less coverage
  • It cannot record audio

5 Best DVR Systems

DVRs are essential components for the setup of your security camera. They help save and store footage from your CCTV camera, hence making accessing the footage very easy. Most newer models of DVRs support multi-channel recording. This means you can connect multiple security cameras ad record simultaneously.

In most cases, you can connect up to 16 cameras. With multiple cameras and simultaneous recording, you can be sure to cover every detail and inch of your premises. However, note that with multiple cameras, you will be recording tons of footage.

So, the best DVR should offer large and dependable hard drives that can retain all of the recordings your cameras capture. Alternatively, to improve your storage, you can include a backup solution to save your footage.

Once you are running out of space, you will be informed. In addition, most DVR system features apps that you can download to remotely monitor camera footage in real-time. Also, they support cloud storage.
