I currently have a sensormatic system. The multiplexer is 16 channels and a simplex that has 9 channels. I want to purchase a dvr but am on a budget and was thinking I could use a single channel dvr the same way I use the time lapsed vcr that is with the system. Is this possible can a single channel dvr be used in this application as to where I can keep all my cameras and record from the multiplexer and simplex in place of the time lapsed vcr.
