Why doesn the computer monitor come with the Digital Video Recorder?
We don’t supply the computer monitor with the DVR because frankly you can get one cheaper and easier locally. Large computer stores such as Best Buy or CompUSA sell these monitors practically at cost. And due to thier heavy weight, they are very expensive to ship (and subject to damage). Also, we found that many of our customers have spare computer monitors available. How does a CCTV digital video recorder work? A CCTV digital video recorder (or “DVR” for short) is essentially a computer that saves security video images to a hard drive. Most security cameras in use today capture an analog picture. The DVR converts the analog signal to digital and then compresses it. Digital compression results in a much better picture than analog compression and its more efficient. Many cameras can be connected to one DVR. DVRs generally come with 4, 8, 16, or 32 camera inputs. The DVR will allow you to view all of these images at once or one at a time, and all of the video is saved to the hard drive.
