Video Cassette Recorders (VCR)

Video cassette recorders (VCR) receive video input and capture data onto analog or digital videotape. Consumer-grade products are not included in this category. Video cassette recorders (VCR) are used to record audio and video signals from television broadcasts and can be programmed for a high-quality standard play (SP) format or a lower quality long play (LP) format. The play format selected determines the speed at which the tape is processed through the video cassette recorder. The LP format allows for more recording time on one videocassette or tape.

Video cassette recorders (VCR) use a tape format known as video home system (VHS). VHS uses a .5 in. wide tape wound between two spools to pass it back and forth over the playback and recording heads of a video cassette recorder. An advanced analog standard, super video home system (S-VHS), was introduced in the 1980s. S-VHS increases the screen resolution from 240 lines to 400 lines.

Video cassette recorders (VCR) are used in video surveillance systems for recording data from a variety of cameras configured through a facility or building. VCRs for video surveillance can also be used for monitoring access to restricted areas and monitoring personnel and visitors to a facility. Video cassette recorders (VCR) give organizations an opportunity to monitor traffic patterns or building usage, and can provide evidence of a breach of security by unauthorized personnel. Many secure facilities use closed circuit television (CCTV) systems along with VCRs. These organizations also maintain a video storage library of the activity in particular rooms or areas.

Digital video cassette recorders (VCR) offer a variety of benefits to organizations using video surveillance or recording equipment. Digital video recorders (DVR) offer more storage capability, easier retrieval of footage and the opportunity to share footage through a computer network. The availability of broadband Internet connectivity has made it more efficient and cost-effective to use a digital video recorder (DVR) as part of a monitoring or recording system.
