GM Security Groups DTR8 is an automatic telephone recorder designed to effortlessly record all of your incoming and outgoing phone calls. As soon as the handset is picked up or the phone is activated the DTR8 will automatically begin recording. As soon as you finish with the call and hang up the phone the DTR8 will go back to stand by mode. This allows you to record all of your conversations throughout the day without having to fumble for your recorder every time you make or receive a call you would like to record. This Telephone recorder is also completely silent on the telephone line. The party you are talking to will not hear any buzzing, hums, or clicking that they would with a cheap consumer recorder.
