smcctv 0 Posted February 10, 2014 Hi, I have been asked to install a Tannoy system to work through the DVR using a mic. Could you experienced installers advice on how to set this up and what type of cable to use. The customers office is down on the ground floor and the Horn speaker is to be installed on the 3rd floor. Cabling to be run outside the property in water tight conduit. DVR will also be fitted into a secure unit on the 3rd floor. Your advice would very much be appreciated.
