Secware_Tech6 Posted October 1, 2009 Share Posted October 1, 2009 I dont know of a reflective unit that can do more than 11m Can you get power of any sort at the other side, or could you use a passive based system? James Quote Link to comment Share on other sites More sharing options...
sparky Posted October 1, 2009 Author Share Posted October 1, 2009 its one of them jobs im afraid there is no chance of getting a cable to the other side a pir system might work if i can find a sensor wich will not pick up a large dog or false alarm on badgers or foxes like in the past do you have any thing in mind Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted October 1, 2009 Share Posted October 1, 2009 NOt with 30m range no. Things that spring to mind are pet tolerant risco external detector or a heavily masked opal / voltek pir. Mounting height would be critical though. Quote Link to comment Share on other sites More sharing options...
