Guest barrett90 Posted October 6, 2005 Share Posted October 6, 2005 Can anyone suggest a good loudspeaker that could be triggered from the alarm output on a Dennard external dome? something compact and decent looking would be preferred as its for a domestic install. There is preinstalled co-ax to the tower positions which means all equipment for the speaker and message must be located at the camera tower position. It only needs to be able to give a short voice warning message. Link to comment Share on other sites More sharing options...

ian.cant Posted October 9, 2005 Share Posted October 9, 2005 Do Dennard domes have alarm outputs? i thought they were inputs actually? Link to comment Share on other sites More sharing options...
Brian c Posted October 9, 2005 Share Posted October 9, 2005 I don't think the domes have inputs or outputs, but the drx receiver has both. If you don't know......ask. Link to comment Share on other sites More sharing options...
ian.cant Posted October 9, 2005 Share Posted October 9, 2005 Well i just checked the PDF's on 2060 domes and DRX receivers and there are no outputs, only inputs. Thinking about it why or from what would you need or trigger an output from a dome? Link to comment Share on other sites More sharing options...
Brian c Posted October 9, 2005 Share Posted October 9, 2005 I checked the drx pdf and it showed 1 alarm output. I think the theory is you wire the detectors to the inputs to drive the ptz, then the output activates to trigger recording or transmission, with the ptz at the appropriate preset. If you don't know......ask. Link to comment Share on other sites More sharing options...

ian.cant Posted October 9, 2005 Share Posted October 9, 2005 Cant with you or the reasons why, i cant find anything like that and cant say ive ever seen an output from a dome or the receiver. But there you go, the other reason would be to trigger a message generator....... Link to comment Share on other sites More sharing options...
Guest Gordon Posted October 18, 2005 Share Posted October 18, 2005 Would a little unit with a PTZ address to activate/deactivate a relay be worth designing ? Also N R Bardwell in Sheffield sell small cheap modules with a built in alert voice but they require + and - 9 volts. Link to comment Share on other sites More sharing options...
