No. A conventional time-lapse recorder can be directly replaced in a CCTV system, giving all the advantages of digital recording immediately, and simply for the cost of the recorder. Maintenance costs for a VCR are very high, is the maintenance cost of a digital recorder even higher? One of the key advantages of digital recorders is that the maintenance costs of are virtually negligible. The recording is made on a hard disk, and hard disks are some of the most reliable electro-mechanical products on the market, with incredibly long MTBF's. No routine planned maintenance is required. Bosch digital recorders have a full 3 years' warranty. What are some of the key concerns in determining what type of digital recorder is needed? The type and use of the recording is critical. To simply replace a time-lapse recorder a single channel DVR is the obvious choice. For multichannel time-lapse recording with occasional event recording with network possibilities, the Divar is ideal. If the highest quality (real time) or alarm recording is the goal then an MPEG2 based recorder such as Hi-Q can be selected. Extending the recording or archive time is usually by adding storage arrays. When building a larger or distributed recording system the network accessibility and control is of paramount importance.
