The advent of digital video recorders (DVR) has made some significant changes in surveillance procedures and advantages. DVRs can, for example store substantially more data than could be stored on VCR tapes that were in wide use until recently. The video data can be easily stored on discs and is very portable, making it ideal when there is an issue of storage space.

In addition, the data can be transmitted over the Internet, allowing the viewer to access the video from remote locations such as a home computer or hand held. The video can be viewed by multiple users with password protection. Computer software programs can also add the application of monitoring employee or family-member Internet access and other computer activities such as emailing.

DVR Technology - A Step Into the Future

In surveillance, the clearer the image, the better the information. DVR far out performs real-time monitoring and VCR technology to the extent that identification is much more reliable than with either of the older methods. DVRs also offer live-action stop and restart features that allow for easier viewing when something questionable is observed.

This is virtually the same technology that is available for home use as advertised under a variety of brand names. When you need to see what's going on at remote locations at your business site, or when you simply want to keep track of what your children are doing on their computers, DVR technology can supply you with the video or data you need. The cost is reasonable, and it is easy to learn how to use the technology.
