A digital video recorder (DVR) is a high-quality compact recorder that combines the functions of a recorder and multiplexer into one unit. Having no tapes to maintain, replace, or rewind means that this recorder can be set up once and virtually forgotten about until a review of the video becomes necessary. It also dramatically reduces the downtime for maintenance or repair that is generally associated with VCRs.
Storage and recording time vary between models however the larger the hard drive, the longer the images will be stored.
Many DVR systems allow for connection from a personal computer. If the proper ports are open in the firewall, and a static IP (or DDNS) is employed, the connection can be viewed remotely outside the office as well.
A DVR has an operating system and a hard drive (like a computer) so it is important to surge protect and battery backup (UPS) the system to avoid damage and downtime.
