Digital Video Recorder (DVR) - Unlike VCRs, Digital Video Recorders (DVR) record video to a computer hard drive or other media such as a CD or DVD. This makes a Digital Video Recorder DVR easy to maintain because there are no bulky tapes to change or the risk of losing video quality when recording over previous footage. Except for the World's Smallest DVR, all of our other Digital Video Recorders can be operated and monitored remotely from anywhere in the world using the Internet. While the surveillance video data is stored on the DVR it can be protected from loss caused be operating errors, tampering and accidents. Covert (Hidden) and Standard systems are available.NOTE: If you require more information, want an estimate, or a surveillance system installed in a business or home anywhere in the United States, call us today for more information at 877.509.2721.
