Video Surveillance: Protecting Your DVR Investment
But there’s no doubt that digital video recorders or DVRs have created a solid niche. And then there’s network video recorders (NVRs) starting to play the “Kill Bill” role. Still the transition deserves a contemplative business decision-making process. Selecting the right equipment in the rapidly changing DVR market can be daunting. You can justify and protect your investment by carefully analyzing a few key factors, according to Gareth McClean, director of R&D, American Dynamics, San Diego.
Resolution will depend upon what is recorded. If you simply want to capture an image of a car in a parking lot using an analog camera, for example, one CIF will do. With one CIF, you would be able to determine if there is a vehicle in the camera’s view, but would not be able to capture finer details, such as the license plate number. Two CIF should be used to record more detailed images, such as a license plate number or a person’s face. However, two CIF also requires twice as much disk space so it’s important to take those storage costs into consideration, said Gareth McClean.
