·         DVRs utilize proprietary PC based devices containing analog to digital capture cards.

·         NVRs utilize ‘off the shelf’ PCs with a standard Ethernet interface for receiving video and controlling PTZ devices.

·         The least expensive PC available today running as an NVR can outperform most DVRs.

·         Remote video access is accessible thru the actual DVR only.

·         NVR technology allows secure, direct access to the video feeds independent of the NVR itself.

·         Multiple PCs can be loaded with NVR software for additional capability at no additional licensing cost.

·         DVR failures require the DVR manufacturer to service the unit or replace it.

·         NVR failures can be repaired or replaced by the user, PC manufacturer or retail point of purchase very quickly.

·         DVR performance is basically fixed. It can not be easily augmented and has physical limits. Performance augmentation requires premium cost components sold by the manufacturer.

·         NVRs can be replaced and upgraded in a matter of minutes. Performance can be significantly augmented over short periods of time. This allows new technology offerings to be immediately implemented.

·         Retired NVRs are completely viable PCs which can be sold or used for other services.

·         DVRs require manufacturer approved components and accessories.

·         NVRs can implement most any device compatible with the generic PC platform.

·         DVR maximum resolution is limited by analog camera technology and capture card design. Native analog resolutions have approached their limits.

·         NVR maximum resolution is effectively unlimited. As camera resolutions continue to increase, NVRs can receive and decode the images without modification.

·         NVR systems support Power over Ethernet standards. This allows cameras to be cabled with a single connection each, eliminating the need for a power drop.

·         NVRs can implement multiple IP Camera devices and most any analog camera or PTZ device simultaneously.

·         NVRs can operate via any IP network topology including low cost wireless transmission systems from most any wireless vendor.

·         NVR technology is based on multiple standards from cabling to PC operating systems.

·         Installation costs of NVR systems can be significantly lower than comparable analog based cabling installations.

·         NVR technology has shown long term reliability in Federal prison environments, municipal, educational any most every other professional and private discipline.
