Digital Video Recorder: Not Just Your TiVo
When you think of a Digital Video Recorder (DVR), the first thing that comes to mind is more than likely the TiVo sitting on a shelf near your TV. However, a DVR doesn’t just record television shows. Specific types of CCTV DVRs can be used to record the video (and audio) that your surveillance cameras capture. Of course you have to own a DVR that is specifically made for this purpose.
The types of DVRs used for security are the PC-based and standalone DVR. It is a good idea to be familiar with the basics behind these when choosing a security DVR for your home or business.
Let’s take a look at both.
PC-based
The PC-based DVR can come in either a tower (normal PC) or a rack mount form. It includes all of the same components as your household or work computer, as well as a video capture card, or cards, which is the device that captures the video and audio from your cameras. The PC typically runs on a Windows operating system. This type is easier to upgrade and modify in the future. It also offers better video recording quality, more advanced features and can easily be integrated with your alarm or POS system. A PC-based DVR is good if you plan on setting up a surveillance system for large projects, such as casinos, banks and airports.
Standalone
A standalone DVR looks like and is about the same size as a standard DVD or VCR player. All of the software and components are built-in, and the DVR runs on either a Linux-based or proprietary-based operating system. Because a standalone only runs one application, it is less likely to experience software failure. These systems are easy to install and use, offer a variety of functions and are less expensive than PC-based DVRs. If you are installing a security camera system in your home or small office, a standalone DVR is the way to go.
As you continue to build your home or business surveillance system, it is important to compare between the two types and decide which will be best suited for your operation.
