------------- found some ultrasonic since I wrote this --- But if any of you have some options I would be interested in knowing about them
We use one of our PLC 5/20s for security in addition to other control functions.
We also send signals to a Hikvision NVR via a 1771-OW16. It captures an image of the detection zone and sends it to our email, DropBox image directory, phones etc.
We have been looking for another sensor to provide outdoor intrusion detection in an area. PIRs either send tons of nuisance alarms or don't trip when they should.
We prefer something like that but have not found a PIR that is good for security.
IR is not really what we want. We want to use something that detects something moving in a zone. I have heard of some sonic devices using inaudible signals but have not found any.
Anybody have some ideas?
Thank you!
