What is a DVR?
Digital video recorders (DVR) allows video images to be saved onto a computer hard drive. It is a revolutionary technology that is replacing old “time lapse video” due to DVR’s better reliability, better image quality, better capabilities, better viewing options and better access and storage of video data.
Choosing the right DVR
There are many factors that go into choosing the right DVR (digital video recorder) that must be decided before purchasing. To start with, you will want to consider how many channels you will need. Each channel is a camera input and most DVRs come with 4, 8, 16 or 32.
Secondly, the size of the hard drive comes into play. While it is impossible to say exactly how much time you can record with any given hard drive, you can estimate that at maximum settings with a typical DVR you get about 1 hour per channel per gigabyte. So with a 16 channel DVR you are using 16 gigs per hour with the highest settings. By lowering the resolution, recording only on motion, or lowering the frame rate you can greatly increase the amount of time recorded allowing you to get a week or even a month’s worth of video before it begins to record over itself. The other advantage of motion detection recording is you no longer need to spend wasted time watching countless hours of useless video waiting to see if something happened.
The next deciding factor is networkability. A lot of the current DVRs are set up to be accessible remotely so you will want to think about whether or not you want to be able to see the cameras from another office, or home or perform remote backups. This also means you won’t need to purchase additional monitors to be able to view all of the cameras. Instead, each PC workstation can just access it on their individual computers.
