Some of the benefits of a well-designed and installed camera system are prevention of internal and external theft, use in preventing and in litigation of Workmen's Compensation cases (even just to make sure all safety rules are being obeyed). Also it has always been a factor in increasing productivity, not to mention the ability of a supervisor to better manage the entire site. Camera systems using Digital Video Recorders now act like small computers with larger than normal hardrives. These new smart "DVR's" may be programmed to record only when there is motion on screen. This not only stretches the recording time tremendously but allows easier retrieval of an event by zeroing in on times when the screen was active. Viewing cameras over your high speed internet connection is easily achieved by the use of high security software.
