text: DVRs and NVRs have a single point of failure with all video being recorded on that device. If the recorder fails, a hard-drive fails or the recorder has connectivity issues, video evidence is lost. Enterprise solutions that include RAID technology and a failover server can get very expensive. Fortunately, cloud backup can provide an always-available, highly secure backup of your video. Kastle Systems includes 24x7 on-site recording PLUS event video backed up to the cloud, from 3 days to 2 years depending on your needs. The best part is, this video is at the highest resolution supported by the camera, and does not consume much bandwidth.
