goalie 0 Posted June 10, 2005 I was first thinking of using Video motion detection to record intruders in an outdoor (fenced off) area. Lots of false alarms so I thought maybe to incorporate PIRs or something like that. Any recommendations for what I need? Share this post Link to post Share on other sites
baywatch 1 Posted June 10, 2005 We use outdoor PIR units manufactured by Voltec for low budget systems & Redwall units for higher value installations. Both units can be obtained in anti-pet form. We also use a perimeter detection system that can be physically mounted on the fence to detect movement & this is much less liable to false alarms than PIRs, costs a lot more however.

rory 0 Posted June 10, 2005 Are you in the US or UK ..? In the US, Optex for normal outdoor beams, id stay away from their PIRs as they still fasle alot, or dont work half the time if you have them in PET or turn their sens down. I use beams on most jobs. Redwall if you want ultimate protection. Or like what Baywatch said about the fence sensors ... Share this post Link to post Share on other sites
goalie 0 Posted June 11, 2005 I'm in Canada or the 51st State. Does optex make the fence sensors too? I noticed they had some photoelectric beams on their site, is that what it is? Share this post Link to post Share on other sites
rory 0 Posted June 12, 2005 No, a beam is just an Invisible beam that goes from one to the next, when it is crossed, sends a signal to trigger the alarm. Ive never used the fence systems, never had a need to down here, but: http://www.safeguards.com/index.cfm?pg=10&level=3&sid=0 The buried sensors are also quite neat.

baywatch 1 Posted June 12, 2005 We use a systems made by a company called Senstar Stellar, their website is: http://www.senstarstellar.com/Main.cfm?URLPage=Home&URLSubPage=Main Or look at the videos on: http://www.senstarstellar.com/Main.cfm?URLPage=ProductsLists&URLSubPage=Video They explain the different systems quite well. The buried system is almost totally undetectable. Share this post Link to post Share on other sites
